JavaScript - Onblur/onfocus Event Problem
Realizing that form input placeholders aren't universally recognized among browsers, I began changing all of mine using onblur and onfocus handlers instead. As an example, I used the following code, which works in most cases:
Code: <input type="text" name="example" maxlength="5" value="Example" onblur="if(this.value=='') this.value='Example';" onfocus="if(this.value=='Example') this.value='';"/> At first, I coded all of the inputs without a value attribute. But, when the page initially loaded, the fields would load empty, and the value/placeholder wouldn't appear until the field had been "focused" and then "blurred" again. Adding the value attribute seemed to correct that problem, again, for the most part. I have some text fields that appear only after I select a particular radio button or select option. Problem is, when the radio is clicked, the field appears, but even with the value attribute in place, the field appears void. I'm not sure what is different, or what I'm doing wrong. Here's the javascript code with the radio button (note:everything works except that the "placeholder" doesn't show when the field first appears): Code: function showfield() { document.forms[0].otherRelation.value = ""; document.getElementById("newBox").style.display = "none"; var r = document.forms[0].relation; var len = r.length; for (var i =0; i<len; i++) { if (r[i].checked && r[i].value == "Otherrelation" ) { document.getElementById("newBox").style.display = "inline"; } } } <input type="radio" name="relation" value="Otherrelation" onclick="showfield()"/>Other <span id = "newBox" style="display:none">: <input type = "text" name="otherRelation" size="35" value="Your Relationship" onblur="if(this.value=='') this.value='Your Relationship';" onfocus="if(this.value=='Your Relationship') this.value='';"/> </span> Thanks for any help. Sorry so long. Similar Tutorialsgreetings, i have a function that sets the onfocus and onblur event for every item in a table which then tells it to the change the class name. for some reason this doesn't seem to be working with the <select> inputs. i have heard it has something to do with how the option list re-loads itself??? Code: function setTableActivation(){ tableDiv = document.getElementById("tables"); tables = tableDiv.getElementsByTagName("table"); count = tables.length; for(var h=0;h<count;h++){ var table = tables[h]; table.accessKey = h; table.onfocus = function(){tables[this.accessKey].className = "activeTable";}; table.onblur = function(){tables[this.accessKey].className = "searchreal";}; for(var i=0;i<table.rows.length;i++){ row = table.rows[i]; row.accessKey = h; row.onfocus = function(){tables[this.accessKey].className = "activeTable";}; row.onblur = function(){tables[this.accessKey].className = "searchreal";}; for(var j=0;j<table.rows[i].cells.length;j++){ cell = table.rows[i].cells[j]; cell.accessKey = h; cell.onfocus = function(){tables[this.accessKey].className = "activeTable";}; cell.onblur = function(){tables[this.accessKey].className = "searchreal";}; for (var k = 0; k < cell.childNodes.length; k++) { if (cell.childNodes[k].nodeType == document.ELEMENT_NODE) { cell.childNodes[k].accessKey = h; cell.childNodes[k].onfocus = function(){tables[this.accessKey].className = "activeTable";}; cell.childNodes[k].onblur = function(){tables[this.accessKey].className = "searchreal";}; if(cell.childNodes[k].tagName == "SELECT"){ } } } } } } } Hi, can someone show me why I cant get the onfocus and onblur to loop thru the function showTextContent() when entering the words one, two, three or four. I have tried for days, googled and lost a lot of hair trying to figure it out. http://www.data-affiliates.com/DL234...5/attempt.html Code: <html> <!-- Created on: 08.08.2009 --> <head> <meta http-equiv="Content-Type" content="text/html;

All it will do is go out and find every textarea, then change the onblur/onfocus functions to something that I created. Here's my problem, when I am going through each textarea object, I can't seem to find a way to reference the object from within the function. See down in that for loop? When I say tAreaSniffer(i), the i ends up being overwritten each time. This makes the value of i in each object to be 3(since there are 3 textareas). I have used javascript in the past, however now I am getting back into it and having trouble. Thanks guys, Here's my code: Code: <html> <head> </head> <body> <form> <textarea name="t1" rows="4" cols="20"></textarea> <textarea name="t2" rows="4" cols="20"></textarea> <textarea name="t3" rows="4" cols="20"></textarea> </form> <script type="text/javascript"> var sniffer; var textareas = document.getElementsByTagName('textarea'); var counter = 0; function tAreaSniffer(tArea)//, oldCont) { alert(tArea); //var curCont; = tArea.value; counter++; sniffer = setTimeout(function(){tAreaSniffer(tArea)}, 1000); } for(var i=0; i<textareas.length; i++) { textareas[i].onfocus = function(){tAreaSniffer(i);};//, textareas[i].value);}; textareas[i].onblur = function(){clearTimeout(sniffer);}; } alert("HEYO"); </script> </body> </html> Hi all, I am working on a site which is in a frameset. There is content area, a footer and a workqueue on the right. Now what I do is poll the workqueue every 30 seconds, check if there are any changes to any queues and if so, I make them go bold and red and play a beep. That's no problem, that works fine. The trouble is I am trying to make the title flash "New Item" if the window is out of focus (Minimised would be better but dont think that is possible to detect). The flashing bit is no problem, it's the triggering when the windows out of focus that is a problem. Applying events to the window object doesn't work. The closest I have come to making it work is this, but it doesn't work in firefox... Code: var debugwin = window.open("", "newwin", "width=300, height=300, scrollbars=1"); debugwin.document.open(); debugwin.document.write("<HTML><TITLE>Debug Window</TITLE><BODY>"); debugwin.document.write("</BODY></HTML>"); debugwin.document.close(); function addDebug(msg) { debugwin.document.body.innerHTML = msg + "<BR/>" + debugwin.document.body.innerHTML; } <!--<frameset onblur="workitemAlerts.setItemAlerts(false);" onfocus="workitemAlerts.setItemAlerts(true);" id="titleframeset" rows="<%= HEADER_FRAME_RESTORED %>,*,<%= FOOTER_FRAME_HEIGHT %>" framespacing="0" border="0" frameborder="0">--> <frameset onblur="addDebug('Blur 1st frameset');" onfocus="addDebug('Focus 1st frameset');" id="titleframeset" rows="<%= HEADER_FRAME_RESTORED %>,*,<%= FOOTER_FRAME_HEIGHT %>" framespacing="0" border="0" frameborder="0"> <frame onblur="addDebug('Blur frame 1');" onfocus="addDebug('Focus frame 1');" noresize scrolling="no" framespacing="0" border="0" frameborder="0" id="titlebar" name="titlebar" src="<wfmt:headerpage />"> <frameset onblur="addDebug('Blur 2nd frameset');" onfocus="addDebug('Focus 2nd frameset');" id="mainframeset" cols="10,*,<%= MAIN_FRAME_RESTORED %>" framespacing="0" border="0" frameborder="0"> <frame onblur="addDebug('Blur frame 2');" onfocus="addDebug('Focus frame 2');" noresize framespacing="0" border="0" frameborder="0" name="leftpad" src="mainColourFill.jsp" scrolling="no"> <frame onblur="addDebug('Blur frame 3');" onfocus="addDebug('Focus frame 3');" noresize name="windmain" src="<wfmt:postloginpage />" scrolling="auto"> <frame onblur="addDebug('Blur frame 4');" onfocus="addDebug('Focus frame 4');" noresize framespacing="0" border="0" frameborder="0" name="queues" src="workqueues.jsp" scrolling="no" style="BORDER-RIGHT: gray 1pt solid;"> </frameset> <frame noresize scrolling="no" framespacing="0" border="0" frameborder="0" name="footerbar" src="footer.jsp"> </frameset> I have popped up a little window to help me view debug away from the window so I can focus and blur and still see the output to see what events are triggering.

TIA, Dale Hi I've just found out that a piece of code is not working as expected in certain browsers - but the way in which it goes wrong is not consistent, so maybe it's something wrong with my code. Oddly enough, it works exactly as I was expecting when viewed in IE. Here's the code... any help would be much appreciated. Thanks Code: <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>Untitled Document</title> <script type="text/javascript"> function fillboxAddress() { if (document.getElementById('tbAddress').innerHTML == '') { document.getElementById('tbAddress').innerHTML = 'Address'; } } function clearboxAddress() { if (document.getElementById('tbAddress').innerHTML == 'Address') { document.getElementById('tbAddress').innerHTML = ''; } } </script> </head> <body> <p><textarea name="tbAddress" rows="2" cols="20" id="tbAddress" onfocus="clearboxAddress()" onblur="fillboxAddress()">Address</textarea></p> </body> Hi, I'm having some problems with some javascript events firing in the wrong order under certain workflows. Here's the gist of it: I have a form with many fields, mostly input type = text. Each field as an OnBlur and OnFocus event tied to javascript functions. IE's website (http://msdn.microsoft.com/en-us/libr...=vs.85%29.aspx) states that "The onblur event fires on the original object before the onfocus or onclick event fires on the object that is receiving focus." and that is exactly what happens when tabbing through the fields. The tricky part is that it doesn't perform this way when CLICKING to another field. When clicking to another field it performs the new field's OnFocus first, and then the first field's OnBlur event after. This is bad because the OnFocus sets a global variable's value to whatever value is in that box at the time it gets focus and if the onblur validation fails, that value is inserted back into the box. So what's happening is the validation for field 1 fails and the value from field 2 is then written into field 1. This also seems to only happen when the page is opened as a modal window as opposed to just opening the page on it's own. It doesn't happen in FireFox, I've only been able to get it to happen on IE 8 + (haven't tried any other browsers.) Anyone else have this happen to them? Does it sound like an IE bug? Thanks I have an onfocus event that makes a textarea large and then an onblur event that sets it back to a smaller textarea. If I click the textarea the onfocus event is triggered but if I go straight to submit the form the onblur event is triggered and the form is not submitted unless i hit submit twice. How can i get the form to submit? Can i put an "if" statement in the onblur event to see if the form is being submitted then just submit the form otherwise run the onblur event? Code: <style type="text/css"> .textarea { background-color: #ffffff; color: black; font-family: Arial, sans-serif; font-size: 8pt; font-weight: normal; border-style: solid; border-width: 1px; border-color: aaaaaa; height: 18px; width: 50%; overflow: hidden; } .textarea2 { background-color: #ffffff; color: black; font-family: Arial, sans-serif; font-size: 8pt; font-weight: normal; border-style: solid; border-width: 1px; border-color: aaaaaa; height: 100px; width: 50%; overflow: auto; } </style> </head> <body> <script> function enlargeBox(v,n,c){ document.theForm.elements[n].className='textarea2'; } </script> <form method="POST" name="theForm" action="newProcess.php"> site<br> <textarea class = "textarea" name = "site" onblur = "this.className='textarea'" onfocus = 'enlargeBox(this.value,this.name,this.className)' rows="1" cols="20"> this is a test for this new texfield to textareathis is a test for this new texfield to textareathis is a test for this new texfield to textareathis is a test for this new texfield to textareathis is a test for this new texfield to textareathis is a test for this new texfield to textareathis is a test for this new texfield to textarea</textarea> <br> Contact:<br> <input type="text" onclick="this.select();" name="contact" value="" class="textfieldlp" size="50"> <p> </p> <p><input type="submit" value="submit" name="B1"></p> </form> Hi, I have a problem in javascript, where entering a value in the textbox during onblur I am doing a refresh to bring in the updated records from the DB , before the on blur refresh is completed if the user clicks the search button (onclick) during the first click nothing is happening as the refresh is still going on. During the second click when the on blur refresh is completed it will open a popup. The problem here is I am unable to disable/inactivate the search button untill the refresh is completed as well as I dont have any control over the refresh time as well. This is like already an event is in progress and where we are invoking another event which is not having any effect. In such case how i can handle this scenario? Thanks. Hi everyone, The following code has an onblur event in the input fields so that if someone clicks out of the field without typing something in it, the original label, ie. 'First name' is reinserted into the field. The field is also being validated by some php code, however the onblur event creates a problem because the form still submits even if a name isn't typed into the field. It's assuming that 'First name' is an entry and therefore isn't validating it correctly. It was suggested that on the submit event of the form, there would be a function that checks if the value is First Name then return false, but then otherwise return true. As my javascript skills are very basic, I wondered if someone could help me with this code to solve this issue? Appreciate any help. Code: <input id="firstname" name="firstname" type="text" value="First name" onfocus="if (this.value == 'First name') this.value=''" onblur="if (this.value == '') this.value='First name'" /> <?php if (ValidatedField('index_965','index_965')) { if ((strpos((",".ValidatedField("index_965","index_965").","), "," . "1" . ",") !== false || "1" == "")) { if (!(false)) { ?> <span style="color: red"> First name is required </span> <?php //WAFV_Conditional index.php index_965(1:) } } }?> Hello all, As this is an active javascript programming forum...i'm really hoping i'll get a solution for my problem...please help me out....

Hello The onFocus events I have come across seem to deal with changing the background colour of the field on a Web form, so that the active field is a different colour to the background field of the other form elements. But how would I use onFocus simply to have the cursor moving in the active field (on a Web form it might be the 'name' field for example)? The code I have at the moment looks like this: Code: <!DOCTYPE etc <head> <title>Janko</title> <style type="text/css"> body { font-family: Arial, Sans-Serif; font-size: 13px; } #inputArea { font-family: Arial, Sans-Serif; font-size: 13px; background-color: #d6e5f4; padding: 10px; width:310px; } #inputArea input, #inputArea textarea { font-family: Arial, Sans-Serif; font-size: 13px; margin-bottom: 5px; display: block; padding: 4px; width: 300px; } .activeField { background-image: none; background-color: #ffffff; border: solid 1px #33677F; } .idle { border: solid 1px #85b1de; background-image: url( 'blue_bg.png' ); background-repeat: repeat-x; background-position: top; } </style> <script src="jquery-1.2.6.min.js" type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function(){ $("input, textarea").addClass("idle"); $("input, textarea").focus(function(){ $(this).addClass("activeField").removeClass("idle"); }).blur(function(){ $(this).removeClass("activeField").addClass("idle"); }); }); </script> </head> <body> <h2><a href="www.jankoatwarpspeed.com">Janko At Warp Speed</a></h2> <p>This example is from the article <a href="http://www.jankoatwarpspeed.com/post/2008/05/22/CSS-Message-Boxes-for-different-message-types.aspx">Enhance your input fields with simple CSS tricks</a></p> <div id="inputArea"> <label for="txtName"> Name</label> <input id="Text16" type="text" /> <label for="txtEmail"> Email</label> <input id="Text17" type="text" /> <label for="txtWebsite"> Subject</label> <input id="Text18" type="text" /> <label for="txtComment"> Message</label> <textarea id="Textarea6" rows="4" cols="30"></textarea></div> </body> </html> Many thanks Steve Hi all, I have a REALLY strange problem - maybe a new set of eyes can help me. Look at these pieces of code: This generates the code Code: <!-- BEGIN code_open --> <dl class="codebox"> <dt>{L_CODE}: <a href="#" onclick="autoSelect(this.parentNode.nextSibling); return false;">{L_SELECT_ALL_CODE}</a> </dt> <dd> <pre onfocus="doTest(this)"> <!-- END code_open --> <!-- BEGIN code_close --> </pre> </dd> </dl> <!-- END code_close --> Test JS just for now Code: var doTest = function(a) { alert(a); } The HTML as seen by Firebug Code: <dt>Code: <a href="#" onclick="autoSelect(this.parentNode.nextSibling); return false;">Select all</a></dt><dd> <pre onfocus="doTest(this)"> Test Test Test </code></pre></dd> One little problem... it doesn't work!!! And yes the function being called is accessible. For that matter, simply putting "alert('hello')" into the "onfocus" also fails. I even checked at W3CSchools to verify that: (1) The <pre> element supports "onfocus" (it does). (2) I ran their "Try it" and "onfocus" is working in my browser (Firefox 3.6.17, WinXP 32). What the heck??????????? Any ideas? Thanks! -- Roger Hi All, Need a bit of help here, need this SELECT to submit the page and end up at the below URL, correctly passing the GET values through the string. <code> <select name="dir-fact-misma" id="dir-fact-misma" class="text100" tabindex="" onChange="alta_nueva.action='alta.php?page=p2#alta'; return true;"> <option value="Si" <?php if(!isset($_POST['dir-fact-misma']) || $_POST['dir-fact-misma'] == 'Si') print "Selected='Selected '"; ?>>Si</option> <option value="No" <?php if(isset($_POST['dir-fact-misma']) && $_POST['dir-fact-misma'] == 'No') print "Selected='Selected '"; ?>>No</option> </select> </code> the form in which this SELECT is placed needs to be submitted so that other fields in the form are not lost, they are saved in Session Variables. the same javascript but activated through an onclick event works perfect elsewhere in the same form with the following code, i think its the onChange that doesn't work for some reason. <code> <input name="p1" type='submit' id="p1" onclick="alta_nueva.action='alta.php?page=p1#alta'; return true;" value='1' /> </code> the page is programmed in PHP.

I wanted to call 2 functions inline, but I can't seem to do it. So I have added the function (add_event_listeners) to the function (load_doc) that is usually called. JavaScript debugger is saying: Code: Uncaught TypeError: Cannot read property 'addEventListener' of null JavaScript: PHP Code: //Get httpobject function getHTTPObject() { var http = false; if (window.XMLHttpRequest) { http = new XMLHttpRequest(); } else if (window.ActiveXObject) { http = new ActiveXObject("Microsoft.XMLHTTP"); } return http; } //This function attaches events to elements. var addEvent = function( elm, evt, fun ) { if ( elm.addEventListener ) { elm.addEventListener( evt, fun, false ); } else if ( elm.attachEvent ) { elm.attachEvent( 'on' + evt, fun ); } else { elm [ 'on' + evt ] = fun; } }; function load_doc(doc, parent) { add_event_listeners(); document.getElementById(parent).innerHTML = "Fetching data..."; var http = getHTTPObject(); if (http != undefined) { http.onreadystatechange = function() { req_doc(doc, parent, http); }; http.open("GET", doc, true); http.send(""); } } function req_doc(doc, parent, req) { if (req.readyState == 4) {//only if req is loaded if (req.status == 200) {//And if its okay document.getElementById(parent).innerHTML = req.responseText; } else { document.getElementById(parent).innerHTML = "Error fetching data: " + req.status + "\n" + req.statusText; } } } //Script used to hide elements.

When you touch / move in the element, the console.log is being fired. If you continue to drag / move outside the element, the console.logs still continue to fire. So it seems that once the event is started it's no longer confined to the element its being assigned to. Any ideas on how to keep it bound to the element? Here is the code: Code: $('#someElm').bind('touchmove',function(e){ e.preventDefault(); var touch = e.originalEvent.touches[0] || e.originalEvent.changedTouches[0]; console.log(touch.pageY+' '+touch.pageX); }); Thanks in advanced. Hello, I have a script I am using which works great, except when I copy the code and have multiple events it only shows the first one. This I believe is because it's calling the first class name of it's kind. I want the class's to be named the same thing (css styling) and because the site is going to be dynamically driven, but is there a way to modify my script so that instead of looking for the first class it recognizes the right class associated with the button clicked. If anyone can help me fix this problem I am having I would be most appreciative.. Code: <script language="javascript"> function toggle() { var ele = document.getElementById("commpopup"); if(ele.style.display == "block") { ele.style.display = "none"; } else { ele.style.display = "block"; } } </script> <div class="togglecomment"> <div class="popup" id="commpopup"> <div class="commentbtn"><a href="#"><img src="images/commenticon.png" align="absmiddle" />Comment</a></div> </div> <div class="button"><a href="javascript:toggle();"><img src="images/comment_btn.jpg" /></a></div> </div> I'm trying to simulate a textfield on a canvas; that is when clicking on the text box a cursor appears and blink. My problem here is when I create more than one object, the event listener will work only on the last object created. Here is my code: Javascript Code: var canvas; var ctx; var MousePosX; var MousePosY; var Cursor_Width = 1; var Cursor_Height = 21; var Height = 27; var LapseTime = 800; function init(CanvasName) { canvas = document.getElementById(CanvasName); ctx = canvas.getContext("2d"); } /* Create Textfiled */ function Textfield(x, y, w) { Textfield.prototype.x = x; Textfield.prototype.y = y; Textfield.prototype.w = w; Textfield.prototype.Cursor_PosX = x + 3; Textfield.prototype.Cursor_PosY = y + 3; // draw rectangle ctx.beginPath(); ctx.rect(this.x, this.y, this.w, Height); ctx.closePath(); ctx.stroke(); // listen for mouse click event canvas.addEventListener("mousedown", function(evt) { // calculate mouse coordination on canvas MousePosX = evt.clientX - canvas.offsetLeft; MousePosY = evt.clientY - canvas.offsetTop; // if mouse coordination is within texfield display cursor if((MousePosX > Textfield.prototype.x && MousePosX < (Textfield.prototype.x + Textfield.prototype.w)) && (MousePosY > Textfield.prototype.y && MousePosY < (Textfield.prototype.y + Height))) { Textfield.prototype.cursor(); } }); } /* Cursor for textfield */ Textfield.prototype.cursor = function() { // alert("good"); ctx.beginPath(); ctx.strokeStyle = "black"; ctx.rect(this.Cursor_PosX, this.Cursor_PosY, Cursor_Width, Cursor_Height); ctx.closePath(); ctx.stroke(); setTimeout("Textfield.prototype.animate_cursor()", LapseTime); }; /* Change color of cursor to white to make blinking effect */ Textfield.prototype.animate_cursor = function() { ctx.strokeStyle = "white"; ctx.stroke(); setTimeout("Textfield.prototype.cursor()", LapseTime); }; HTML Code: <!DOCTYPE HTML> <html> <head> <style> #MyCanvas { border: 1px solid #000000; } </style> <script src="widgets1.js"></script> <script> window.onload = function () { init('MyCanvas'); var tf1 = new Textfield(10.5, 10.5, 150); var tf2 = new Textfield(10.5, 50.5, 150); }; </script> </head> <body> <br /><br /><br /> <center> <canvas id="MyCanvas" width="700" height="500"> </canvas> </center> </body> </html> What i want to achieve here is have my event listener on any textfield created on the canvas. Hello all, I'm wondering if anyone can offer advice on a simple (or so I thought!) Javascript menu I'm trying to create. I'm creating 5 buttons, using event handlers (onmouseover etc) which exchange 1 image for another. I did the first one fine - it worked perfectly, but as soon as I added the rest they all stopped working properly. The best I have got, is that the last link will do what it's supposed to regardless of which link I hover over! Which is strange. So the browser seems to be actioning the last thing on the list if that makes sense. It seems to me that I need to add an "if" type attribute, so "if" I hover over the home button, the home images change, as opposed to the last one on the list. This is the code I have so far for a single link - the rest are copies of this with adjustments made to the imgname and image sources obviously..... <div style="width:80px; height:20px;margin-top:20px;margin-left:85px;"><a href="about.html" onMouseOver="return changeImage()" onMouseOut= "return changeImageBack()" onMouseDown="return handleMDown()" onMouseUp="return handleMUp()" ><img name="aboutbutton" src="img/aboutn.png" width="80" height="20" border="0" alt="javascript button 1"></a> <script language="JavaScript"> upImage = new Image(); upImage.src = "img/abouth.png"; downImage = new Image(); downImage.src = "img/aboutc.png" normalImage = new Image(); normalImage.src = "img/aboutn.png"; function changeImage() { document.images["aboutbutton"].src= upImage.src; return true; } function changeImageBack() { document.images["aboutbutton"].src = normalImage.src; return true; } function handleMDown() { document.images["aboutbutton"].src = downImage.src; return true; } function handleMUp() { changeImage(); return true; } </script></div> Any suggestions on where I am going wrong would be wonderful. Thanks so much in advance! All the best |
