JavaScript - Uncaught Typeerror: Cannot Set Property 'onreadystatechange' Of Undefined
The line "xmlHttp.onreadystatechange = function()" Does the following error, i dont know whats wrong.
The code: Code: function MakeRequest() { var xmlHttp = getXMLHttp(); var page = document.getElementById("page").value; var content = document.getElementById("code").value; xmlHttp.onreadystatechange = function() { if(xmlHttp.readyState == 4 && xmlHttp.status==200) { HandleResponse(xmlHttp.responseText); } } xmlHttp.open("POST", "edit.save.php", true); xmlHttp.setRequestHeader("Content-type","application/x-www-form-urlencoded"); xmlHttp.send("page="+page+"&content="+content+""); } function getXMLHttp() { var xmlHttp try { //Firefox, Opera 8.0+, Safari xmlHttp = new XMLHttpRequest(); } catch(e) { //Internet Explorer try { xmlHttp = new ActiveXObject("Msxml2.XMLHTTP"); } catch(e) { try { xmlHttp = new ActiveXObject("Microsoft.XMLHTTP"); } catch(e) { alert("Your browser does not support AJAX!") return false; } } } } function HandleResponse(response) { document.getElementById('SavedFile').innerHTML = response; } Similar TutorialsWhat i'm trying to accomplish is two things. To select the page i want to load in each tab then select how many of thoughs tabs i wish to open. When the number of tabs is selected i want it to launch. i also have a refresh button that works i just can't get the windows to load. by the way for this project i want it to open the same url that is selected on all of the tabs. Here is what i have: <html> <head> </head> <form name="myform"> <select name="mySelectbox"> <option value="">Choose a destination...</option> <option value="http://www.yahoo.com/">YAHOO</option> <option value="http://www.google.com/">GOOGLE</option> <option value="http://www.altavista.com/">ALTAVISTA</option> <option value="http://www.amazon.com/">AMAZON</option> </select> </form> <form name = "myform2"> <select name = "numberWindows" onchange = "openThem()"> <option value = "0">Choose....</option> <option value = "1">TEST</option> <option value = "2">2</option> <option value = "3">3</option> <option value = "4">4</option> <option value = "5">5</option> </select> </form> <script> function open_win() { var myurl = parseInt(document.myform.myselectbox.value); window.open("myurl"); } </script> <script type = "text/javascript"> var i; function openThem() { var val = parseInt(document.myform2.numberWindows.value); for (i =0; i < val; i++) { open_win(); } } document.write('<form><input type=button value="Refresh To Do Again" onClick="history.go()"></form>') </script> </body> </html> Can someone please help. I'm just trying to learn how this is done. Thanks. Good day! Here is the problem, setting the slider to the site, here's an example: http://wowslider.com/best-jquery-sli...near-demo.html and do not connect different effects on this slider, such as buttons on the sides and smooth shifting slides. When you see the code generates this error: Uncaught TypeError: Cannot read property addEventListener' of undefined I do not know what this error, help, error on this site: http://uh219381.ukrdomen.com/ Or here's the code: http://uh219381.ukrdomen.com/themes/...1/wowslider.js sorry for my English I've been using this javascript (menu.js) for a drop down navigation menu for my site. Everything works well on it but in multiple browsers I get this error occurring on line 7 and 16 which is the d.className = "menuHover"; and d.className = "menuNormal"; Code: function expand(s) { var td = s; var d = td.getElementsByTagName("div").item(0); td.className = "menuHover"; d.className = "menuHover"; } function collapse(s) { var td = s; var d = td.getElementsByTagName("div").item(0); td.className = "menuNormal"; d.className = "menuNormal"; } Im new to this whole thing. What needs to be done to solve this? Appreciate the help. Hi, This is my first post while learning Javascript and jQuery as total noob. I have something like this: Code: var desc = "This is your title and here is even more that might be added so that we can get at least 60 characters or so"; var desc = desc.trim().substring(0, 40).split(" ").slice(0, -1).join(" ") + "...more"; alert(shortText ); It is actually being used on a page that calls a description from a MySQL table, but this example fails in exactly the same manner. Although FF and other browsers successfully initiate the script with errors, but IE loops endlessly and freezes up. FireBug reports "reference to undefined property a[d]". Using jQuery 1.6.2. I'm not really sure what property is undefined here and how this can work without freezing IE. Thanks in advance for any help! AJ Hello, I'm hoping someone can help me with this. I have 3 pages that I need to put into my framework, they are products, shopping cart and billing. At the moment they work perfectly fine. Here is a live example - http://www.cems.uwe.ac.uk/~r4-george...g/products.php Now, I have a framework for a whole website that I need to put these pages into. (http://www.cems.uwe.ac.uk/~r4-george/wp4/index.php) The index uses a switch statement to go between pages. Here is the index.php PHP Code: <?php # index.php /* * This is the main page. * This page includes the configuration file, * the templates, and any content-specific modules. */ // Require the configuration file before any PHP code: require_once ('./modules/config.inc.php'); // Validate what page to show: if (isset($_GET['p'])) { $p = $_GET['p']; } elseif (isset($_POST['p'])) { // Forms $p = $_POST['p']; } else { $p = NULL; } // Determine what page to display: switch ($p) { case 'about': $page = 'about.inc.php'; $page_title = 'About This Site Again'; break; case 'products': $page = 'products.inc.php'; $page_title = 'Products on this site'; break; case 'this': $page = 'this.inc.php'; $page_title = 'This is Another Page.'; break; case 'that': $page = 'that.inc.php'; $page_title = 'That is Also a Page.'; break; case 'contact': $page = 'contact.inc.php'; $page_title = 'Contact Us'; break; case 'search': $page = 'search.inc.php'; $page_title = 'Search Results'; break; // Default is to include the main page. default: $page = 'main.inc.php'; $page_title = 'Site Home Page'; break; } // End of main switch. // Make sure the file exists: if (!file_exists('./modules/' . $page)) { $page = 'main.inc.php'; $page_title = 'Site Home Page'; } // Include the header file: include_once ('./includes/header.inc'); echo "<div id=\"content\">"; // Include the content-specific module: // $page is determined from the above switch. include ('./modules/' . $page); // Include the footer file to complete the template: include_once ('./includes/footer.inc'); ?> It uses the .inc.php files located in the modules folder to switch between pages. Here is my products.inc.php - PHP Code: <? include("includes/db.php"); include("includes/functions.php"); if($_REQUEST['command']=='add' && $_REQUEST['productid']>0){ $pid=$_REQUEST['productid']; addtocart($pid,1); header("location:shoppingcart.php"); exit(); } ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Products</title> <script language="javascript"> function addtocart(pid){ document.form1.productid.value=pid; document.form1.command.value='add'; document.form1.submit(); } </script> </head> <body> <form name="form1"> <input type="hidden" name="productid" /> <input type="hidden" name="command" /> </form> <div align="center"> <h1 align="center">Products</h1> <table border="0" cellpadding="2px" width="600px"> <? $result=mysql_query("select * from products"); while($row=mysql_fetch_array($result)){ ?> <tr> <td><img src="<?=$row['picture']?>" /></td> <td> <b><?=$row['name']?></b><br /> <?=$row['description']?><br /> Price:<big style="color:green"> £<?=$row['price']?></big><br /><br /> <input type="button" value="Add to Cart" onclick="addtocart(<?=$row['serial']?>)" /> </td> </tr> <tr><td colspan="2"><hr size="1" /></td> <? } ?> </table> </div> </body> </html> This is EXACTLY the same code as the working example. The products get listed correctly but the problem I have is the 'Add to Cart' button fails to work. Live example - http://www.cems.uwe.ac.uk/~r4-george...php?p=products Everything is in the right directory. When I inspect the 'Add to Cart' button in chrome I get the following - Quote: Uncaught TypeError: Cannot set property 'value' of undefined addtocart index.php:51 (anonymous function)index.php:83 onclick Any help is really appreciated, I'm struggling to see what I have done wrong. I don't know whether it's a Javascript problem. If you need any of the code from other pages I can post it too. Thanks in advance. I do not really understand what is happening to my code but it just tell me the following: Code: document.getElementById("#movingword") is null How could the movingword be null when I have declared it in my code?

Now most of the class works it can send the data("POST" or "GET") cross domain the only problem seems to be firing the onreadystatechange PHP Code: this.open = function(sMethod, sUrl){ this._readyStateUpdate(); this._handle.onreadystatechange = this._readyStateUpdate; this._handle.ontimeout = this.ontimeout(); this._url = sUrl; this._method = sMethod; } As you can see i have its set to fire the _readyStateUpdate on the onreadystatechange so why is it not fireing, This is tested in FireFox 3.5, ComitBird(Firefox 3.2 Core), Google Chrome and IE and it dose not work in all of them as i know there is a bug with FireFox 3.5 and Firebug wich im a developer i have got it but thats why im testing in GG and IE Any help would be greatly appreciated I'm trying to diagnose the javascript part of an ajax script: Code: <form> <ul id='May120128AM' name='apt_time' value='May120128AM'> <input type="hidden" id='May120128AMhidden' name="user_id" value='May120128AM'> </form> <script type="text/javascript"> <!-- var request; request = new XMLHttpRequest(); function checkData() { alert(request.readyState); } var apt_time = encodeURIComponent(document.getElementById(May120128AM').value); var userid = encodeURIComponent(document.getElementById(May120128AMhidden').value); var parameters = "apt_time"+apt_time //+"&"+"user_id"+userid; request.open("POST", "/cgi-bin/my_script.php", true); request.onreadystatechange = checkData; request.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); request.send(parameters); //--> </script> The checkData script puts each readyState in an alert box, so I know the javascript is firing. If I change the red line of code to this, the alert boxes no longer pop up, so I assume the javascript is not firing: Code: var parameters = "apt_time"+apt_time+"&"+"user_id"+userid; I thought name/value pairs were written like this: Code: name1=value1&name2=value2 I though that was exactly what the red line of code was doing. Does anyone know why it isn't firing? UPDATE: This works: Code: var parameters = "apt_time=+apt_time+&user_id=+userid"; I don't know why the above works and the other doesn't. They both look like they do the same thing - this: Code: apt_time=value1&user_id=value2 Hey all, This is a problem that I've tried various ways round - consider the following code: Code: if (window.XMLHttpRequest) { this.xhr = new XMLHttpRequest(); } else if (window.ActiveXObject) { this.xhr = new ActiveXObject("Microsoft.XMLHTTP"); } this.xhr.onreadystatechange = function () { if(this.readyState == 4) { if(this.status == 200) { editor.loadObject.doLoad(); } else window.console.log("Loader: Loader Error code " + xhr.status); } } the code is called from my "loader" object which in turn is loaded from another object in this case "editor" (editor initiates the loader object by this.loadObject = new loader(this.ident + "loader");). In the example above I have had to hard-code the variable "editor" (i.e. the original object) because when I define this.xhr.onreadystatechange as a function, anything outside the function is outside of it's scope, so I can't for example define this.callerObject and put it in place of editor. This is a nuisance as you can imagine - Any ideas how to do this? Many thanks Edd I am trying to figure out that if the function "xmlhttp.onreadystatechange=function()" returns true the whole function "function checkUser(str)" should return true as well....so not sure how to do it. i have banged my head since long so please advise! Here is the code below: -------------------------------------------------------- function checkUser(str) { var sp = document.getElementById("msgs"); if (str=="") { document.getElementById("msgs").innerHTML="Username cannot be empty."; return false; } if (str.length <= 6) { document.getElementById("msgs").innerHTML="Username cannot be less than 6 characters and must not start with a number or a special value"; return false; } if (window.XMLHttpRequest) { //code for IE7+, firefox, chrome, opera, safari xmlhttp=new XMLHttpRequest(); } else { //code for old IE xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { if (xmlhttp.responseText === 'FOUND') { sp.style.color = "red"; sp.innerHTML = "[ERROR]: The username \"" + str + "\" already exist. Please try a different name."; return false; } else if (xmlhttp.responseText === 'NOT FOUND') { sp.style.color = "blue"; sp.innerHTML = "Username: VALID"; return true; } } } xmlhttp.open("GET", "checkUser.php?q="+str,true); xmlhttp.send(); } I've been working on a web-site and I've run into a problem. None of the buttons I've created will access the functions that they're supposed to access. When I used the JavaScript console in Chrome it threw the error Uncaught ReferenceError: (function) is not defined I've looked over it for syntax errors, but I couldn't find any. Am I missing anything?

Hey folks. I am needing some help with an error I'm getting from a project I'm working on. First off let me preface this all with the fact that I'm a total javascript noob. I'm really trying to understand what I'm doing wrong. So any help or advice is MORE than welcome. Here's what is happening. I found this code that will duplicate a row in a table and modifiy the name of a input in the row. Well for my purposes I have two different tables I need to work with. (each one idividually) So I changed the code a bit to make it accecpt a variable to use for the table name. (before it was static) and now I'm getting a error. Code: Error: uncaught exception: [Exception... "Component returned failure code: 0x80004003 (NS_ERROR_INVALID_POINTER)" nsresult: "0x80004003 (NS_ERROR_INVALID_POINTER)" location: "JS frame :: http://www.tourandtravelnow.com/admin/scripts/faxPageScript.js :: addRow :: line 14" data: no] This is the old code that would work (only for one of the tables) Code: var clone; function cloneRow(){ var rows=document.getElementById('mytab').getElementsByTagName('tr'); var index=rows.length; clone=rows[index-1].cloneNode(true); var inputs=clone.getElementsByTagName('input'), inp, i=0 ; while(inp=inputs[i++]){ inp.name=inp.name.replace(/\d/g,'')+(index+1); } } function addRow(){ var tbo=document.getElementById('mytab').getElementsByTagName('tbody')[0]; tbo.appendChild(clone); cloneRow(); } onload=cloneRow; and here is my code that doesn't work. Code: var clone; function cloneRow(mytab){ var rows=document.getElementById(mytab).getElementsByTagName('tr'); var index=rows.length; clone=rows[index-1].cloneNode(true); var inputs=clone.getElementsByTagName('input'), inp, i=0 ; while(inp=inputs[i++]){ inp.name=inp.name.replace(/\d/g,'')+(index+1); } } function addRow(mytab){ alert(mytab); var tbo=document.getElementById(mytab).getElementsByTagName('tbody')[0]; tbo.appendChild(clone); cloneRow(mytab); } onload=cloneRow(mytab); So like I said any help would AWESOME! have a great day. Kevin. I can't get any info from Firebug except that one line, uncaught exception [object Object]. The code fully worked, then I needed to make it dynamically create Sortables from the scriptaculous library based on how many X were in a table in my database, which I've done, and I'm thinking it may be a simple slight parse error of some type, I'm not too good with Javascript, because now my script barely works. I've double checked the script's source code, the PHP variables are exactly what they should be. Code: print<<<HERE Sortable.create('sortlist$box', { tag: 'img', overlap:'horizontal',constraint:false, containment: $list, dropOnEmpty: true, onChange: function(item) { var list = Sortable.options(item).element; if(changeEffect) changeEffect.cancel(); changeEffect = new Effect.Highlight('changeNotification', {restoreColor:"transparent" }); }, onDrop: function(item) { var thing=Sortable.options(item).element.identify(); var anchors = document.getElementById(thing).childNodes.length-2; if(anchors > 20){ alert('This box had 20 creatures in it already, your last action has not been saved.'); window.location.reload(); } else{ new Ajax.Request("saveImageOrder.php", { method: "post", parameters: { data: Sortable.serialize("sortlist$box") } }); } } }); HERE; $box++; } ?> }); </script> if you solve this I'll send ya $10 via paypal I am and seem to remain newbie ... I have a JS script that presents a series of "pages" with different questions inside a single HTML file, by rewriting certain <div>s. I have an object like this that contains the questions and information about answer labels etc (the idea is that this should be easy to modify for someone who doesn't know JS): Code: var Questions = [ { "question" : "How good is this?", "labels" : ["excellent","very good","good","bad","very bad","awful"], "page" : 0 , "random" : false , "type" : "default", "varname" : "allgood" }, { "question" : Change[curCase]+"What do you think now?", "labels" : BetterLabels, "page" : 1 , "random" : true , "type" : "default", "varname" : "betteradapt" } ] This object is initialized when the page loads, and a function reads the total number of pages by getting the maximum number of the "page" property across elements. Later, the object is accessed by thenextQuestion() function which uses the "page" property to looks whether each element belongs on the current page , then reads out the properties and presents the question. This works okay. Now the tricky bit: For some questions, their text should be different depending on which case is currently on the screen (Change[curCase]). curCase is different on each page, an integer between 0 and Change.length. I cannot get this to work for the Questions object, probably because the Questions object has been already initialized when the page loaded. How can I get my function nextQuestion() to "re-evaluate" the property "question" for all the elements of the Questions objectwhen nextQuestion() is called , using the current value of "curCase"? nextQuestion() is longer, but the (i think!) crucial bits are he Look whether question belongs on current page and push it onto new array: Code: for (i=0; i < Questions.length; i++) { Questions[i].page = Questions[i].page; if ( Questions[i].page == BlockNum ) { // if the q belongs on the current page QuestionsObjectThisPage.push(Questions[i]); } } Then, extract an array containing the questions, which will then be presented: Code: for (i=0; i < QuestionsObjectThisPage.length; i++) { QuestionsThisPage.push(QuestionsObjectThisPage[i].question) ; } So what I'm looking for is something to change either of these two Object.push() functions so they don't simply take the value they find in the Questions (or QuestionsThisPage) object, but to re-evaluate the code for the "questions" property, taking into account the current value of curCase Phew. I found that really hard to describe; hope it's somewhat clear. I have this simple manual photo slide show. It shows four photos and when you click the next button and it moves one photo over and one photo back for the previous button. I have to moving by changing the CSS property of 'left' by 195 pixels each move. So for it to move next it will subtract 195 pixels from the left property and for moving back it add 195 pixels to the left property. I have the code setup so when you click it changes the property of left to either -195 or 195 pixels but I need it so it actually does the math, not just give it a set value. But I don't know how to do that. Code: function MM_changeProp(objId,x,theProp,theValue) { //v9.0 var obj = null; with (document){ if (getElementById) obj = getElementById(objId); } if (obj){ if (theValue == true || theValue == false) eval("obj.style."+theProp+"="+theValue); else eval("obj.style."+theProp+"='"+theValue+"'"); } } function nextPhoto() { MM_changeProp('fanThumbWrapOne','','left','-195px','DIV') } function prevPhoto() { MM_changeProp('fanThumbWrapOne','','left','195px','DIV') } so where you see -195px and 195px in the functions for nextPhoto and prevPhoto I need those to actually be functions where it subtracts 195px or adds 195px. I am sorry the following code is a bit of a mouthful, but I can't find a better way to display the problem. The code works as expected in Chrome, but not in IE and FF. In IE the error is "Object doesn't support this action" and in FF "setting a property that has only a getter". In Chrome there is no error in the console. There are three javascript <script>...</script>s that exist to display a <td> row in a table with a particular graphic depending on the screen width. The odd thing is that in both IE and FF (and of course Chrome), the first two scripts display perfectly well. Why does the third <script> produce an error? It has exactly the same form as the two before it. I can only guess it has something to do with where it occurs Googling the FF error, it has something to do with trying to set a read-only property, but then why do the first two <scripts> work? They are no different (at least I can't see a difference.) Code: <table border="0" width="100%" cellpadding="0" style="border-collapse: collapse" id="table3768"> <script> if (screen.width > 1280) { document.write("<td valign=\"top\" background=\"..\/..\/img\/lesson2.gif\" width=\"840\" height=\"301\">"); } else { document.write("<td valign=\"top\" background=\"..\/..\/img\/lesson.gif\" width=\"369\" height=\"301\">"); } </script> <p> </p> <div align="left"> </table> <table border="0" style="border-collapse: collapse" cellpadding="15"> <tr> <td width="40"> </td> <script> if (screen.width > 1280) { document.write("<td width=\"300\">"); } else { document.write("<td width=\"165\">"); } </script> <font face="Trebuchet MS" color="#808000">Today's lesson is about setting goals...</font></td> </tr> </table> </div> </td> <td rowspan="3"> <table border="0" cellspacing="0" style="border-collapse: collapse" cellpadding="0" id="table3920"> <tr> <td><img border="0" src="../../img/teltopw.jpg" width="550" height="9"></td> </tr> <tr> <td background="../../img/telbarw.jpg"> <p align="center"> <iframe name="ITV" src="lesson1TV.html" marginwidth="0" marginheight="0" scrolling="no" border="0" frameborder="0" width="480" height="376"> Your browser does not support inline frames or is currently configured not to display inline frames. </iframe></p> </td> </tr> <tr> <td><img border="0" src="../../img/telbotw.jpg" width="550" height="11"></td> </tr> </table> </td> <td align="center"> <a rel="nofollow" target="_blank" href="http://www.apple.com/quicktime/download/"> <img border="0" src="../../img/quicktimeani.gif" width="129" height="184"></a></td> </tr> <tr> <script> if ((screen.width = 1440) || (screen.width = 1400)) { document.writeln("<td valign=\"top\" width=\"100%\" background=\"\/images\/101online\/listening\/lesson16\/notebot2.gif\" width=\"450\" height=\"50\">"); } else if (screen.width <= 1280) { document.writeln("<td valign=\"top\" width=\"100%\" background=\"\/images\/101online\/listening\/lesson16\/notebot.gif\" width=\"294\" height=\"50\">");; } </script> </td> <td valign="bottom"> </td> </tr> <tr> <td valign="bottom" width="100%"> <div align="right"> <table border="0" cellpadding="5" style="border-collapse: collapse" id="table3926"> <tr> <td align="center"> <a onmousedown="soundManager.play('piano','../../media/mp3/piano.mp3'); return true;" href="javascript: goFull('FULLSCREEN/lesson1full.html','info','width=1020,height=760,left=0,top=0,toolbar=no,scrollbars=no,status=no,directories=no,menubar=no,location=no,resizable=no');"> <img src="../../img/poster1ani.gif" border="0" width="95" height="29"></a> <b><font size="1" face="Arial" color="#000080"> ON DISK</font></b></td> <td align="center"><b><font size="1" face="Arial" color="#000080">OR </font></b> <a onmousedown="soundManager.play('piano','../../media/mp3/piano.mp3'); return true;" href="javascript: goFull('CDRIVE/lesson1Cfull.html','info','width=1020,height=760,left=0,top=0,toolbar=no,scrollbars=no,status=no,directories=no,menubar=no,location=no,resizable=no');"><img src="../../img/poster7.bmp" border="0" width="53" height="30"></a> <b><font size="1" face="Arial" color="#000080"> DRIVE</font></b></td> </tr> </table> </div> </td> <td valign="bottom"> <iframe name="sounds" src="../../pagesounds.html" width="160" height="66" marginwidth="1" marginheight="1" scrolling="no" border="0" frameborder="0"> Your browser does not support inline frames or is currently configured not to display inline frames. </iframe></td> </tr> </table> Any light on this would be most welcome! For some reason I run my script and its saying missing } after property list. But I'm not seeing it.

When you search for something on that page and have a display of results, each result has a link that changes a table row's display to visible, and hides the row when clicked again. It doesn't do that in IE7. There are no errors or warning in Firefox's Error Console. But IE7 has an "Error on Page" notice (which does NOT appear in IE8 emulating IE7), that says: Line: 59 Char: 11 Error: Could not get the display property. Invalid argument. The script in question is this, with what would be line 59 indicated: Code: <script type="text/javascript"> <!-- function toggle_visibility(id) { var e = document.getElementById(id); var f = document.getElementById(id + "b"); if(e.style.display == 'table-row') e.style.display = 'none'; else e.style.display = 'table-row'; <<-- This is line 59 if(f.style.display == 'table-row') f.style.display = 'none'; else f.style.display = 'table-row'; } //--> </script> I really don't know what to do, or where to begin. Everything in my limited knowledge seems to be working just fine. Most of my site's visitors use IE8, but enough use actual IE7 that I really need to fix this. Thanks for any help or advice! Liam |
