JavaScript - What "drunk" Teenager Implemented 'cookies' In Javascript?
I am in the process of learning 'JavaScript' and I am having a problem understanding how to delete cookies. I understand that to do delete a cookie you want to set the expiration attribute of the cookie to delete, to any date in the past. My confusion lies in the exact syntax of how to do this. In the example s I have seen in books and on the internet it appears that you must submit the "exact" name/value pair that you originally set the cookie with to delete it. For an example:
var UserId = "MrJones", password = "secret"; var currentDate = new Date(); currentDate.setFullYear(currentDate.getFullYear()+1); document.cookie = encodeURI("userid=" + UserId " + "; " + "password=" + password + "; expires=" + currentDate.toUTCString()); What is the minimum syntax I would need to delete the cookie above? Also, I need clarification on the terminology. Is a single cookie a collection of name/value pairs(also known as crumbs) or is each name/value pair considered a cookie unto itself? Why does the ECMA board allow people on drugs to be part of settings standards for programming languages that will be used by the entire world? I've been reading a book on JavaScript and have had no problems understanding anything until reaching Chapter 9 and the subject of cookies. This syntax is crazy. And the way you add to a cookie by using just an assignment operator? How about a cookie.Add() and a cookie.Delete() method? Similar TutorialsI have inherited some Javascript code from a colleague that was laid off recently, and I know very little about Javascript. I'm hoping someone here can help me out. I'm getting a Javascript error in IE for "Not implemented". Here is the full error that I get: Line: 34 Char: 1 Error: Not implemented Code: 0 And here is the Javascript code that I'm working with. It is located in a separate .js file. I'm not sure why the person who wrote it didn't use semicolons - I thought these were necessary. Anyway, the Javascript: Code: // List all the image files below with the corresponding HTML code var item=new Array() item[0]="<p><a href='case_study.pdf' target='_blank'><img src='graphics/frame1.gif' border='0'></a></p><p class='homepage_quotes_para_pad'><b>“</b>It translates to a quick learning curve and fast product development.<b>”</b></p><p class='homepage_box_para_pad'><i>Developer</i><br>Foo Inc.</p>" item[1]="<p><a href='r_case_study.pdf' target='_blank'><img src='graphics/r-frame2.gif' border='0'></a></p><p class='homepage_quotes_para_pad'><b>“</b>We needed the glue to hold, and it supplied that glue.<b>”</b></p><p class='homepage_box_para_pad'>Systems Manager<br><i>R, Inc.</i></p>" var current=0 var ns6=document.getElementById&&!document.all function changeItem(){ if(document.layers){ document.layer1.document.write(item[current]) document.layer1.document.close() } if(ns6)document.getElementById("customer_logos").innerHTML=item[current] { if(document.all){ customer_logos.innerHTML=item[current] } } // The number of images being rotated is list here if (current==2) current=0 else current++ setTimeout("changeItem()",10000) // Set the time between rotations } window.onload=setTimeout("changeItem()",10000) //--> Now I've looked around the web, and it seems like the error is happening because of that last line (the "window.onload") -- IE doesn't like the way it's written, I guess. I've tried some different suggestions that I found, but they all seem to break the functionality that the Javascript is used for (rotating an image and quote). Any help you can give me is greatly appreciated. Thanks in advance. Hi guys, I have a JS calculator on my website which is basically a load of radio buttons that the user clicks and as they do so a price is calculated in their view. At the moment - the price box starts with a blank box but is essentially "0". Then, as the user select an option, the price appears and then starts to calculate when more than 1 is pressed. All I want to do is have the price start at "300" instead of a blank box or "0". Then the rest of the options calculate onto that. I have tried a variety of ways to achieve it and seem to be missing something! I am pretty new to JS although do have a basic understanding ..... clearly not enough to do this thou! lol Basically imagine 300 is the initial price. That only gets charged once ... Here's my code .... In the <head> Code: <script type="text/javascript"> function getRBtnName(GrpName) { var sel = document.getElementsByName(GrpName); var fnd = -1; var str = ''; for (var i=0; i<sel.length; i++) { if (sel[i].checked == true) { str = sel[i].value; fnd = i; } } return fnd; // return option index of selection // comment out next line if option index used in line above // return str; } function chkrads(rbGroupName) { var ExPg = [ [0,''], [100,"1 extra page"], [200,"2 extra pages"], [250,"3 extra pages"], [300,"4 extra pages"], [350,"5 extra pages"] ]; var ExEm = [ [0,''], [10,"1 extra email"], [20,"2 extra emails"], [30,"3 extra emails"], [40,"4 extra emails"], [50,"5 extra emails"] ]; var ImgBun = [ [0,''], [10,"3 extra image"], [20,"5 extra images"], [30,"7 extra images"], [40,"10 extra images"] ]; var rbtnGroupNames = ['extrapages','extraemail','imagebundles']; var totalprice = 0; var tmp = ''; var items = []; for (var i=0; i<rbtnGroupNames.length; i++) { tmp = getRBtnName(rbtnGroupNames[i]); if (tmp != -1) { switch (i) { case 0 : totalprice += ExPg[tmp][0]; if (tmp > 0) { items.push(ExPg[tmp][1]); } break; case 1 : totalprice += ExEm[tmp][0]; if (tmp > 0) { items.push(ExEm[tmp][1]); } break; case 2 : totalprice += ImgBun[tmp][0]; if (tmp > 0) { items.push(ImgBun[tmp][1]); } break; } } } document.getElementById('QUOTED_PRICE').value = totalprice; document.getElementById('ITEMS_SELECTED').value = items.join('\n'); document.getElementById('PRICE_IN_VIEW').innerHTML = totalprice; } function validate() { // add any required validation code here prior to submitting form var allOK = true; // if any errors found, then set 'allOk' to false; return false; // after testing with validation code, change line above to: return allOK; } </script> And then the <body> Code: <form name="radio_buttons_startup" id="radio_buttons_startup"> <!--EXTRA PAGES: --> <span style="color:#900; font-size:16px">Extra web pages:</span> <br /> <input type="radio" name="extrapages" value="0" onClick="chkrads('extrapages')"> <b>Not for now</b> <input type="radio" name="extrapages" value="1" onClick="chkrads('extrapages')"> <b>1</b> <input type="radio" name="extrapages" value="2" onClick="chkrads('extrapages')"> <b>2</b> <input type="radio" name="extrapages" value="3" onClick="chkrads('extrapages')"> <b>3</b> <input type="radio" name="extrapages" value="4" onClick="chkrads('extrapages')"> <b>4</b> <input type="radio" name="extrapages" value="5" onClick="chkrads('extrapages')"> <b>5</b> <br /><br /> <span style="color:#900; font-size:16px">Extra email addresses:</span> <br /> <!-- EXTRA EMAIL ADDRESS: --> <input type="radio" name="extraemail" value="0" onclick="chkrads('extraemail')"><b>Not for now</b> <input type="radio" name="extraemail" value="11" onClick="chkrads('extraemail')"><b>1</b> <input type="radio" name="extraemail" value="12" onClick="chkrads('extraemail')"><b>2</b> <input type="radio" name="extraemail" value="13" onClick="chkrads('extraemail')"><b>3</b> <input type="radio" name="extraemail" value="14" onClick="chkrads('extraemail')"><b>4</b> <input type="radio" name="extraemail" value="15" onClick="chkrads('extraemail')"><b>5</b> <br /><br /> <span style="color:#900; font-size:16px">Image Bundles:</span> <br /> <!--Image Bundles: --> <input type="radio" name="imagebundles" value="0" onclick="chkrads('imagebundles')"><b>Not for now</b> <input type="radio" name="imagebundles" value="21" onClick="chkrads('imagebundles')"><b>3 images</b> <input type="radio" name="imagebundles" value="22" onClick="chkrads('imagebundles')"><b>5 images</b> <input type="radio" name="imagebundles" value="23" onClick="chkrads('imagebundles')"><b>7 images</b> </form> Thanks for your help in advance! Greetings! Let me start by first stating that I've never really coded Javascript before in my life. Having said that, I'm not an idiot and I can generally pick up on things relatively quickly . So, now to the point. I'm currently creating a site in which I've incorporated Protoswitcher (http://cssrevolt.com/upload/files/pr...her/index.html). From what I can tell, it's a relatively simple script. Now the catch is that I wanted to have more than one switcher on my site. And this is where I get stuck. What I did initially was to basically copy the JS file (protoswitcher.js) and rename it something else (userbar.js, for example). I then changed the various places in the script which were previously for "var ProtoSwitcher" to "var UserBar", etc. I managed to get it all to work fine. Both the boxes show up, and they both work as they should (clicking on them changes select bits of CSS). Now the problem I'm having is that the original protoswitcher uses cookies to remember a persons preferences. I cannot for the life of me figure out how to get the "new" protoswitcher (userbar.js) to work with cookies as well. Any help would be much appreciated, and I'm sure I can give you a few dollars for your time . Please let me know if I haven't made sense. TLDL: I want to be able to use several protoswitchers with working cookies. I don't know how. Code: for(i=0;i<document.getElementsByName('checkresult_".$i."').length;++i){ if(document.getElementsByName('checkresult_".$i."')[i].checked){ thisurlext+=document.getElementsByName('checkresult_".$i."')[i].value; checkedlength++; if(i+1<document.getElementsByName('checkresult_".$i."').length){ if(document.getElementsByName('checkresult_".$i."')[i+1].checked){ thisurlext+='+'; } } } }; Let's say I check verses 1, 2, 3, 6 I want the Javascript not to ignore the + between the 3 and the 6: Code: <div id="txt_kjv0_1_1_0" style="float: left; background-color: rgb(234, 232, 200); margin: 0px; width: 178px; height: 497px; border: 1px solid rgb(122, 16, 16); padding: 5px 5px 0px; overflow-y: auto; overflow-x: hidden;"> <input id="sc0" value="kjv" type="hidden"> <p id="regular[]" name="bibletext" style="float: left; text-align: left; width: 155px; display: block; padding: 0px 2px; font-size: 12px;"><input id="check0_0" name="checkresult_0" onclick="" value="1" type="checkbox"><span style="font-weight: bold; margin: 2px;">1</span>In the beginning God created the heaven and the earth.</p> <p id="regular[]" name="bibletext" style="float: left; text-align: left; width: 155px; display: block; padding: 0px 2px; font-size: 12px;"><input id="check0_1" name="checkresult_0" onclick="" value="2" type="checkbox"><span style="font-weight: bold; margin: 2px;">2</span>And the earth was without form, and void; and darkness was upon the face of the deep.

I seriously could use as much help as possible! Hello, I run a online gaming website, and I'm having problems with certain websites iframing our games. Actually I'm ok with iframing, as long as they include the banner ad located just beneath our games. But often times unscrupulous webmasters will iframe only the game, preventing us from generating any revenue from the banner ad (and costing us additional bandwidth charges). I'm hoping to find a way to detect the dimensions of the iframe, so that I may dynamically resize the game, in order to include the banner ad within the iframe. Does anybody know how to extract the "height" and "width" attribute values from an <iframe> tag sitting on a different site? Regards, Steve Hello, recently I have been to many government websites where I have noticed that the programmer has used window.open() method in JavaScript to link to different pages instead of using <a> tags! I was just getting curious to know whether it is normal or has it been used due to security concerns(if any, I don't know)? Any comments? Hi all, I'm having a bit of a problem..

Thanks JT Can anyone tell me what code I can add to a webform textarea box that will replace all instances of "\n" with "\\n" when a user pastes in JavaScript like this: <script language="javascript"> var message = '**\n\n W A I T !\n\n CLICK CANCEL\n TO STAY ON THE CURRENT PAGE.\n\n I HAVE SOMETHING FOR YOU!\n\n**'; var page = 'http://google.com'; </script> <script language="javascript" src="http://siteactor.com/test.js"></script> The form is on a .php page. The form posts via a .cgi script. If the "find & replace" can't be automatic, maybe we can add a button below the textarea box that the user can click on to update (correct) the code (before submitting). I am not a programmer... so any specifics you can give me will be much appreciated. Thank you. i am trying to make a comment editor with iframe, and want to trigger the change of content inside iframe, the following code cant work. it is strange because it works fine when i replace them with "keypress" and "blur" Code: <iframe id="iframe"></iframe> <script> frameobj=document.getElementById('iframe').contentWindow; // IE frameobj.attachEvent('onpropertychange', function(){alert();} ); //FireFox frameobj.addEventListener('input', function(){alert();} , false); </script> This is my first post. I am reading "Javascript The Good Parts" ~ The Method Invocation Pattern Page 28 and tried this, var myObject= { value:0, increment:function(inc){ this.value+= typeof inc==="number" ? inc:1; } } myObject.increment(2); alert(myObject.value); but alert(myObject.value); is returning a value of "2", when it should return "3".

Hi I am trying to load html stream directly into webbrowser in delphi. The html contains java script. It loads xml and xsl files and display the xml content in the web browser. I got an error, says access denied for the command xmlDoc.load(fname); If I save the html into a file, test.html, and double click it, it is fine, no problem. The code is actually copied from w3schools.com. the html code as followed: <html> <head> <script> function loadXMLDoc(fname){var xmlDoc; if (window.ActiveXObject) { xmlDoc=new ActiveXObject("Microsoft.XMLDOM"); } else { alert('Your browser cannot handle this script'); } xmlDoc.async=false; xmlDoc.load(fname); return(xmlDoc); } function displayResult() { xml=loadXMLDoc("catalog.xml"); xsl=loadXMLDoc("catalog.xsl"); if (window.ActiveXObject) { ex=xml.transformNode(xsl); document.getElementById("example").innerHTML=ex; } } </script> </head> <body id="example" onLoad="displayResult()"> </body> </html> The delphi code is procedure TForm1.WBLoadHTML(WebBrowser: TWebBrowser; HTMLCode: string) ; var v: OleVariant; HTMLDocument: IHTMLDocument2; begin memo1.Lines.LoadFromFile('d:\test\htmltxtold.html'); HTMLCode := memo1.Text; WebBrowser1.Navigate('about:blank') ; HTMLDocument := WebBrowser.Document as IHTMLDocument2; v := VarArrayCreate([0, 0], varVariant); v[0] := HTMLCode; HTMLDocument.Write(PSafeArray(TVarData(v).VArray)); HTMLDocument.Close; end; Thanks a lot I am pretty novice. I do not know much about the compilers or how these things run. I do however have a good eye for trends and can figure just about anything out by looking at it. With that; I have a game that uses a exe launcher with a built in patcher. I have found the code for the launcher. There are several "jquery" scripts for basic components like scroll wheel. There are also things like "downloader.js", "inputs.js". I am interested in seeing what (and more precisely how many) ip addresses are being retrieved. I fear this patcher is using a hidden bittorrent like download system. The code for "downloader" is pretty basic. It clearly uses some other script, but I am wondering if you can point me in the direction of a utility to monitor running JS so that I can see what is being returned. Code: _Downloader = function() { this.downloadStatusCallback = null; } _Downloader.prototype = { setDownloadStatusCallback: function(callback) { this.downloadStatusCallback = callback; }, addDownload: function(downloadName, metaUrl, outputPath, authorizationURL) // returns bool { return document.SSNLauncher.SSNLauncher_ReturnBool('addDownload', 'string:' + downloadName + '|' + 'string:' + metaUrl + '|' + 'string:' + outputPath + '|' + 'string:' + authorizationURL + '|'); }, removeDownload: function(downloadName) // returns bool { return document.SSNLauncher.SSNLauncher_ReturnBool('removeDownload', 'string:' + downloadName + '|'); }, getDownloadOption: function(downloadName, optionName) // returns string { return document.SSNLauncher.SSNLauncher_ReturnString('getDownloadOption', 'string:' + downloadName + '|' + 'string:' + optionName + '|'); }, setDownloadOptions: function(downloadName, enableBitSources, enableWebSources) // returns bool { return document.SSNLauncher.SSNLauncher_ReturnBool('setDownloadOptions', 'string:' + downloadName + '|' + 'bool:' + enableBitSources + '|' + 'bool:' + enableWebSources + '|'); }, getDownloadActive: function(downloadName) // returns bool { return document.SSNLauncher.SSNLauncher_ReturnBool('getDownloadActive', 'string:' + downloadName + '|'); }, setDownloadActive: function(downloadName, active) // returns bool { return document.SSNLauncher.SSNLauncher_ReturnBool('setDownloadActive', 'string:' + downloadName + '|' + 'bool:' + active + '|'); } } function __Downloader_reportdownloadStatus(downloadName, state, active, totalBytes, bytesLeft, maxIncoming, averageIncoming, currentIncoming, maxOutgoing, averageOutgoing, currentOutgoing, bytesRead, bytesSent, scanBytesLeft) { if (SSN.Downloader.downloadStatusCallback != null) { SSN.Downloader.downloadStatusCallback(downloadName, state, active, totalBytes, bytesLeft, maxIncoming, averageIncoming, currentIncoming, maxOutgoing, averageOutgoing, currentOutgoing, bytesRead, bytesSent, scanBytesLeft); } } I have tried on several occasions to teach myself programing. I can get the commands and syntax fairly easily, and I am pretty good at 'coming up' with ways to get something done. I just don't have experience in this field (I'm in medical school) so I do not know about the tools and utilities programers use and scouring the internet has been less than fruitful. Anybody capable of pointing me in the direction of finding a utility to monitor running js (if that is even possible =/). I use dreamweaver CS5 to explore js code.

Thank you. Clement Osei. Hi I have developed an internet mapping site which uses an html viewer with various frames to pull in a mapping window, a legend / key and a frame of tools amongst other things. It works absolutely fine in Internet Explorer version 6, but whilst testing it in Internet Explorer 7, my mapping window is not loading up the image. It might seem strange me posting this in a javascript forum but as the error is javascript related I thought I would give it a shot! The error message I am receiving is "Access is denied". After looking online, it appears as though this error could be linked to the use of frames; and those frames trying to access other windows with different document domains?? Does anyone know if new security measures have been implemented in IE7 which restricts the use of frames? My code is below; does anyone notice anything that might give this kind of javascript error? Any help will be greatly appreciated as I do not tend to dable too much in javascript!
