JavaScript - Strange Blur Behaviour
Hi all,
A piece of code I have been working on has a small issue with bluring off a div and I can't working out why. Basically what I do is append divs to the DOM and on double click I make them editable and when I blur they are none editable and I append a new div into the document. I have quickly knock up a small piece of code to illustrate the problem ... Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<style text="text/css">
.dropArea {
color:#757575;
font-weight:bold;
display:block;
margin:0px;
border: 1px dashed #999999;
background-color:#DDDDDD;
left:10px;
right:10px;
/*width:auto;*/
text-align:center;
line-height:20px;
}
.textEditArea {
display:block;
margin-bottom:10px;
border: 1px dashed #999999;
background-color:inherit;
left:10px;
right:10px;
padding:5px;
width:auto;
}
</style>
<script>
function makeEditable(activeZone) {
if (activeZone.className == "dropArea") {
activeZone.innerHTML = "";
}
activeZone.contentEditable = true;
activeZone.className = "textEditArea";
}
function doneEditing(activeZone) {
// if no HTML added, make it a drop zone
if (trim(activeZone.innerHTML) == "") {
activeZone.className = "dropArea";
activeZone.innerHTML = "Drop items from or double click to add text";
} else if (activeZone.addDropZoneAlready == undefined) {
// add a new drop zone underneath
activeZone.title = "Double click to edit text";
activeZone.addDropZoneAlready = "true";
activeZone.zoneType = "textDisplay";
addNewDropZone();
}
activeZone.contentEditable = false;
}
function addNewDropZone() {
var dropArea = document.createElement("div");
dropArea.className = "dropArea";
var appendTo = document.body;
appendTo.appendChild(dropArea);
dropArea.ondblclick = function () { makeEditable(dropArea); };
dropArea.onblur = function () { alert('done'); doneEditing(dropArea); };
dropArea.innerHTML = "Drop items or double click to add text";
}
</script>
</head>
<body onload="addNewDropZone();">
<div onDblClick="this.contentEditable=true;" onBlur="this.contentEditable=false;alert('Done!');" style="background-color:#C0C0C0; width: 500px; height:200px;"></div>
</body>
</html>
The div in the body already works as expected, it alerts "Done!" however divs I append into the document have to blur twice before the onblur fires? I just don't undestand why its doing it. Anybody have any ideas as to what is happening? Thanks, Dale Similar TutorialsHi, I am trying to make an xml file download from my website, so the saveAs window will be open, I checked the forum and found the following code. but instead of saving the xml file it saves the html file. any clue??? are there other ways to do it ? Code: <html>
<script type="text/javascript">
function forceSaveAs (filename){
document.execCommand('SaveAs',null,filename)
}
</script>
<a href='/DVEConfiguration.xml' onclick=\"forceSaveAs('DVEConfiguration.xml_export'); return false\">Download</a>
</html>
I also try to send the xml with the following header but with no success Code: print "Content-type: application/octet-stream\n\n"; print "Content-Disposition: attachment; filename=file.xml;" Dear all I have been working with with window.promt() and i noticed a weird behaviour. In some cases (i do not known why) my prompt cannot get over a certain limit of characters. But in some other cases it can get as many characters as i want. Anyone know about this? Thanks Alex for some reason on my site 2 javascipts are acting strange there is obviously a conflict in them but I have no idea when it comes to javascript. My site can be viewed at www.actioncomputing.co.uk The images on the right hand side use a script which makes them open a window with the enlarged image in, the revolving image below just cycles through other jobs i have done. now problem is when the side images are clicked everything else on page should go dark including the revolving image but it doesnt it stays light and even goes over the top of my close button ( please try clicking on the sds asbuilt image you will see what i mean. my html code is below but i dont think there is a issue here Im thinking there must be a variable thats conflicting between the 2?!?!?

Major thanks to anyone who can help Hi, please can someone help I wanted to blur the text in my formfield when a user clicks on it?! Code: <script language="javascript">
function cbevent()
{
var xx = document.loginform.myusername.blur();
}
</script>
<form name="loginform">
<input type="text" name="myusername" onMouseClick="cbevent()" value="Enter your email address here" />
Hi, I have do a calculation when an user enters the value in the textbox during onblur event. But during the onblur event I need to capture the tabkey (keyCode) and if it is 9 do the calculate else not do that. But the problem is we cannot detect a keyCode for tab in onblur. But for sure I need to use onblur in this case and cannot use onkeydown as this will have impact on the UI screen for this particular scenario. How to go about this? in the textbox I am calling onblur = "test()" Please provide a helping hand. Thanks. I have been working on this code for days and I cannot get it right!!! Can anyone please give me any pointers. It should have an error message that pops up on same line as text boxes when into is not entered property! Thanks in advance!

Please see a simple example below: Code: <script language="javascript" type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.js"></script>
<select name="select1" id="select1" onfocus="$(this).blur();">
<option value=""></option>
<option value="">1</option>
<option value="">2</option>
<option value="">3</option>
<option value="">4</option>
</select>
This all works fine in IE and FF but in chrome the options are still shown after clicking the element. I've been racking my brains for hours on this and, no matter what method I use, I can't get this to work correctly in Chrome. Can anyone suggest a way I can get this to work? Thanks in advance! I have these "editable" divs in my document. When you click them, a text box comes up and you type something and push enter. It changes what's in the div. There is also a blur event associated with the text box. When the user tabs or clicks away, it fires the blur event. Here lies the problem. I have other elements on the page that are clickable. I don't want those clickable things to fire their events if the user is clicking away from the text box, ie. the blur event. This isn't a problem is the user pushes tab, for instance. So my thought was that if i know how the user blurred (via keyboard, or clicking) i could take the appropriate action. Any ideas? I have a JavaScript that remembers the values of a form by creating cookies for each input element onblur. I cannot figure out though how to exclude one input field from being remember. It would be document.getElementsByTagName('input')[15] Every time I try to add an if/else statement in using that line, the script doesn't work altogether. Code: window.onload = function() {
rememberFormInputs('rma', 'input-');
}
/**
* Set a cookie
* @param string cookie name
* @param string cookie value
* @param string cookie expiration counter in days
* @param string cookie path
* @param string cookie domain
* @param bool secure?
*/
function setCookie(name, value, expires, path, domain, secure) {
var today = new Date();
today.setTime(today.getTime());
if (expires) {
expires = expires * 1000 * 60 * 60 * 24;
}
var expires_date = new Date(today.getTime() + (expires));
document.cookie = name+"="+escape(value) +
((expires) ? ";expires="+expires_date.toGMTString() : "") +
((path) ? ";path=" + path : "") +
((domain) ? ";domain=" + domain : "") +
((secure) ? ";secure" : "");
}
/**
* Get a cookie value
* @param string cookie name
*/
function getCookie(name) {
var start = document.cookie.indexOf(name + "=");
var len = start + name.length + 1;
if ((!start) && (name != document.cookie.substring(0, name.length))) {
return null;
}
if (start == -1) return null;
var end = document.cookie.indexOf(";", len);
if (end == -1) end = document.cookie.length;
return unescape(document.cookie.substring(len, end));
}
/**
* Remebers form inputs after you fill them in
* @param string form id to remember fields
* @param string a prefix to prepend to all cookie names. (prevent naming conflicts)
*/
function rememberFormInputs(form_id, prefix) {
var form = document.getElementById(form_id);
var els = document.getElementsByTagName('input');
for (var i = 0; i < els.length; i++) {
var el = els.item(i);
if (el.type == 'text') {
el.onblur = function() {
var name = this.name;
var value = this.value;
setCookie(prefix + name, value, 90);
};
var old_value = getCookie(prefix + el.name);
if (old_value && old_value != '') {
el.value = old_value;
}
}
}
}
Does anyone have a solution? I would really appreciate it :] Hello. I'm using the keyup event for an input box to check for the Escape key (keyCode 27). I'm then using this to hide a related select element. It works okay apart from IE(8) of course . How can I prevent IE carrying on with its normal Escape behaviour? If tried a number of things, most recently: Code: e.cancelBubble = true; if ( e.stopPropagation ) e.stopPropagation(); return false; but it, IE, is insistant. I tried switching to 'keydown' but it went a bit wonky.. Andy. Hi I'm banging my head against this problem and I'd really appreciate some help. I think the problem is cause by my lack of understanding of how the browser (firefox 3.6.3) handles focus. A simplified version of my problem is: I've defined the function Code: function two_focus()
{
document.getElementById("two").blur();
alert("hello");
}
then in the body I have the form with two text boxes Code: <input id="one" type="text"><input id="two" type="text" onfocus="two_focus();"> When the page is loaded and I click in the second textbox I get the alert, all well and good. I OK the alert box, but when I click on box 1, or anywhere on the page for that matter, the function is called and the alert comes up. I just don't understand why the focus is being returned to the second box when I click anywhere in the browser window. Any comments will be gratefully received. Hey all, I have a rather complicated program so I'm going to try and make it a little simpler - the problem is with the following function: Code: this.onInsertSuccess = function (paramsArray) {
var result = Array();
result[0] = {};
result[0][this.params.idfield] = paramsArray.id;
result[0][this.params.titlefield] = "NEW ITEM";
result[0][this.params.displayfield] = 1;
console.log(this.displayArray.length);
for (x = 0; x < this.displayArray.length; x++) {
this.displayArray[x][this.params.displayfield] = x + 2;
result[result.length] = this.displayArray[x];
newParams = {idfield:this.params.idfield, id:this.displayArray[x][this.params.idfield], table:this.params.table, displayfield:this.params.displayfield, order:(x+2)};
this.load.updateItem(newParams);
}
this.displayArray = Array();
for (x = 0; x < result.length; x++) {
this.displayArray[x] = result[x];
}
this.display();
}
Here's a simplified version: Code: onInsertSuccess = function (id) {
var result = Array();
result[0] = {};
result[0][this.params.idfield] = id;
result[0][this.params.titlefield] = "NEW ITEM";
result[0][this.params.displayfield] = 1;
for (x = 0; x < this.displayArray.length; x++) {
this.displayArray[x].displayorder = x + 2;
result[result.length] = this.displayArray[x];
}
this.displayArray = result;
// this just updates the display and has no effect on displayArray
this.display();
}
What's happening is that the first time this is called, displayArray appears to update correctly and a "NEW ITEM" appears at the top of my list. The next time the function is called, displayArray consists of only two results - each "NEW ITEM" - this continues to be the case when the function is called again. the initial displayArray is this: Code: this.displayArray = [{'clid': "1", 'name': "Yorkshire Digital Awards", 'displayorder': "1"}, {'clid': "2", 'name': "Screen Yorkshire", 'displayorder': "2"}, {'clid': "3", 'name': "SureStart Selby District", 'displayorder': "3"}, {'clid': "4", 'name': "Mencap", 'displayorder': "4"}, {'clid': "5", 'name': "York St. Johns", 'displayorder': "5"}, {'clid': "6", 'name': "Mobstar Media", 'displayorder': "6"}, {'clid': "7", 'name': "Wheatfields Hospice", 'displayorder': "7"}, {'clid': "8", 'name': "The National Railway Museum", 'displayorder': "8"}];
I've left the original function in because I fully appreciate that it may be another function that's causing this problem! I thought also it could be to do with accidentally assigning references rather than values (hence the adaption of the result assignment at the end of the function in the full code). Any ideas? Many thanks Edd Hi I'm looking for solutions to play a movie file (it can be any format) on a keyboard press. I have this 'textsizer' code so far which I have adapted to work with swapimage but wondered if it would be possible to adapt this to play a movie too. function textsizer(e){ var evtobj=window.event? event : e //distinguish between IE's explicit event object (window.event) and Firefox's implicit. var unicode=evtobj.charCode? evtobj.charCode : evtobj.keyCode var actualkey=String.fromCharCode(unicode) if (actualkey=="a") MM_swapImage('Image1','','marta3.jpg',1) if (actualkey=="z") MM_swapImgRestore('Image1','','marta.jpg',1) } document.onkeypress=textsizer Hope someone can help Thanks I have 9 boxes which I can drag around an invisible grid however when the onMouseDown function is called for the first time on each of the boxes, they behave erratically, then once all boxes have been clicked once, the entire script works as it should. I've tried using default values when declaring the variables however it doesn't seem to do anything. Does this happen with anyone else, anything obvious I'm missing. Code: <html>

Hi. I have a JavaScript that resizes an image held within an Iframe. It works perfectly, BUT only works if there is an alert box in the code. /*Image resizing scripts - Dependant on page size!*/ /////////////////////////////////// function Im_Resize() { var imheight = 550; /*Change the IFrame CSS*/ iframeheight = imheight + 15; /* +15px for the x-axis scroll bar*/ var IFrame = document.getElementById('MainFrame'); IFrame.style.height = iframeheight + 'px'; alert('after iframe size - before im change'); /*Change the Image CSS*/ var innerdoc = IFrame.contentDocument || IFrame.contentWindow.document; Image1 = innerdoc.getElementById('MainImg1'); Image1.style.height = imheight + 'px'; } If I take the alert box out the code just doesn't work?? I thought that it was that during the loading of the page an element hadn't been loaded yet, but a delay doesn't work either. If I press 'ok' on the alert box too quick it doesn't work either. In terms of HTML this script is run whenever the page is loaded and is also fired when a click event is detected on one of the divs on the page. Any help would be great Ed Im using an anchor tag with a class specified. When i click the anchor tag which i have displayed using C# it opens as a popup with background disabled. But when i clikc the anchor tag which i displayed using javascript it redirects to the url mentioned and does not open as a popup. C# Code ----------------- Code:
builder.Append("<a href='EditLevelValues.aspx?levelId=" + levelId + "&levelValueId=" + levelValueId + "&levelName=" + levelName + "&levelValueName=" + levelValueName + "&levelValueDescription="+levelValueDescription+"&placeValuesBeforeTB_=savedValues&TB_iframe=true&height=300&width=500&modal=true&' class='thickbox obox'>");
trLevels.InnerHtml = builder.ToString();
JAVASCRIPT CODE ------------------------- Code: strLevelValues += "<a href='EditLevelValues.aspx?levelValueName=" + lvlValueName + "&levelId="+lvlId+"&levelValueId=" + lvlValueId + "&levelValueDescription="+lvlValueDescription+"&levelName=Projects&placeValuesBeforeTB_=savedValues&TB_iframe=true&height=300&width=500&modal=true&' class='thickbox obox'>"; trProjLevel[0].innerHTML = strLevelValues; Sorry if the title is not so good! Im trying my best. I got my new website in jquery and js, but it behaves very strange. It like bugging, and the fading feels not so smooth as it should. Maybe someone know what the problem is? If you go to www.webblord.se/sv/index.php and then click on the first image at the left-panel menu, its a green button with a home image. You will see that the new content dosn't load raelly smooth, more bugging up. And the loading function dosn't disspear... Why :S? I find this strange, basically the alert is displaying the doc_form[i] ID. But i'm getting a JavaScript error come up in a debugger saying: Code: Uncaught TypeError: Cannot read property 'id' of undefined when trying to get the ID for the variable... PHP Code: //Get HTTP object ready var http = getHTTPObject(); var mysql_q; //Count how many fields are in the form var doc_form = document.guess_word_form; for ( var i = 0; doc_form.length; i++ ) { alert(doc_form[i].id); mysql_q += "&" + doc_form[i].id + "=" + document.getElementById(doc_form[i].id).value; } alert(mysql_q); I have an interval set that runs indefinitely (backgrounds switching) or until the viewer stops it. I've noticed that when I close a tab while it's running and revisit the page, it "doubles" the interval and the backgrounds get mixed up. Refreshing the page returns it to normal. Does anyone know how to fix this? I've tried clearing the interval with window.onunload and window.onbeforeunload. I'm thinking it has something to do with firefox not clearing its cache for the tab. I'll look into disabling that. |
