JavaScript - Nested Contenteditable Element Prevents Hyperlink Default Behavior
I've got the following problem. In IE if a contenteditable element is nested inside a hyperlink, clicking on the element prevents the hyperlink default behavior, i.e. navigation to another document. In FF it works fine. How can I solve the problem? Just removing the contentEditable attribute is not a solution since I want this behavior (navigation to another document) only when user clicks the content-editable element with pressed Ctrl key.
Thanks. Similar TutorialsThe code below is supposed to cancel the default form behavior when it finds certain info missing. Currently, however, in spite of detecting missing info it allows the form submission to continue. Anyone see what wrong? Thanks. Code: var DOM = YAHOO.util.Dom;
YAHOO.util.Event.onDOMReady(init);
function init() {
YAHOO.util.Event.addListener("contact_form", "submit", checkForm);
}
function checkForm() {
var fName = DOM.get('f_name');
var lName = DOM.get('l_name');
if (fName.value == "") {
DOM.get('f_name_error').innerHTML = "This field is required!";
fName.focus();
return false;
}
Code: function offPar(){
alert(this.offsetParent.id);
}
function init(){
var mine = document.getElementById("mid");
var other = document.getElementById("inner");
mine.addEventListener("click", offPar, false);
other.addEventlistener("click", offPar, false);
}
window.addEventListener('load', init, false);
HTML :
<div id = "content">
<div id = "mid">
<div id = "inner">
<p class = "par">
</p>
</div>
</div>
</div>
I can add an event listener to the #mid div but I can't to the #inner div. Anyone now why this is? Sorry I can't provide more info. That's all I Know! TTFN John I am working on a function that will style text in a contenteditable div. For example, when Ctrl+b is pressed, <b></b> tags will be inserted around the currently selected text. The problem is that, unlike a textarea, a contenteditable div is not made up of a single text node. Code: function moobar(element,e){
if(e.keyCode == "17"){ //IF CTRL IS PRESSED
var selectionStart = window.getSelection().anchorOffset ;
var selectionEnd = window.getSelection().focusOffset ;
var range = document.createRange(), selection = window.getSelection();
var foobar = document.createElement('div');
if(selectionStart == selectionEnd){
//NO TEXT IS HIGHLIGHTED
//I'LL DEAL WITH THIS PART LATER
} else {
if(selectionStart > selectionEnd){
foobar.innerHTML = element.innerHTML.substring(0, selectionEnd );
element.innerHTML = element.innerHTML.substring(0, selectionEnd ) + "<b>" + element.innerHTML.substring( selectionEnd , selectionStart ) + "</b>" + element.innerHTML.substring( selectionStart );
} else {
foobar.innerHTML = element.innerHTML.substring(0, selectionStart );
element.innerHTML = element.innerHTML.substring(0, selectionStart ) + "<b>" + element.innerHTML.substring( selectionStart , selectionEnd ) + "</b>" + element.innerHTML.substring( selectionEnd );
}
range.setStart( element.childNodes[foobar.children.length+2] ,0);
}
range.collapse(true);
selection.removeAllRanges();
selection.addRange(range);
}
}
Might there be a possible way to find out which child of the editable div the offsets are in? For example, if div1's innerHTML was "Some <b>bolded</b> text" and "ex" was highlighted, would there be a way to find out that anchorOffset is inside div1.childNode[2]? If not, then what I really need are just some general suggestions about where to go from here? I have a div tag that is contenteditable so that users can type in the div. There is a function that adds a link into the div when the user presses a button. I would like the caret to be positioned after the link so that users can continue to type. The link can be inserted many times. Example Code: Code: <div id="mydiv" contenteditable="true" tabindex="-1">before <a href="#">link</a> after</div> I require this code to work in: IE, Firefox, Opera, Safari and Chrome. Can anyone offer any help? Consider the following test page: Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Contenteditable Test</title>
<style>
.test {} [contenteditable="true"] { outline:1px solid red; }
</style>
<script>
function listen(id, eventName, func) {
el = document.getElementById(id);
if (el.addEventListener)
el.addEventListener(eventName, func, false);
else
el.attachEvent('on'+eventName, func);
}
window.onload = function() {
listen('root', 'click', toggle);
listen('test', 'click', toggle);
}
function toggle(e) {
var el = getTarget(e).parentNode;
if (el.id == 'test') {
el.setAttribute('contenteditable', 'true');
} else {
el.setAttribute('contenteditable', 'false'); /* The style of the element should change accordingly. *** BUT *** it DOESN'T!!!! */
alert(el.getAttribute('contenteditable')); /* Confirm that contenteditable is 'false'. */
}
}
function getTarget(e) {
return (window.event == undefined ? e : window.event).target;
}
</script>
</head>
<body>
<div id="root">
<h1>Contenteditable Test</h1>
<div id="test" contenteditable="false">
<p>The quick brown fox jumps over the lazy dog.</p>
</div>
</div>
</body>
</html>
The desired behaviour is: When you click on the test div, the content should become editable (and the style of the div should change accordingly - the test div gets a red outline). When you click outside the test div, the content should become not-editable (and the style of the div should change accordingly - the test div loses its red outline). When you click on the test div, its contenteditable attribute is set to 'true' and it becomes editable, as expected. When you click outside the test div, its contenteditable attribute is set to 'false', as expected, BUT its style does not change accordingly. I would expect it to change because the red outline style is predicated upon contenteditable being 'true' for the element, but the red outline remains even when contenteditable is no longer 'true'. By the way, I have tried 'false', false and 0, all to no avail. Obviously, I can force the style of the element when it is 'deselected', but that is a very ugly hack and will cause a headache if/when I want to change the contenteditable style in the future (I don't want to have to do it in several places - it should be possible to do it just in the CSS). Any ideas why this is happening? Hey all, Whenever firebug detects a js error on a page, it prevents you from interacting with the page, so you can't scroll, you can't click, you can't do anything except close the window. Anyway around this? Thanks. Please advise me: I've successfully called a variety of functions that have no parameter value such as: function expand() //expand() in this line is merely an example But I'm unsuccessful calling a function with a paramter value such as: function expand(id) Here is the the call line: document.addEventListener("DOMContentLoaded", expand(id) , false); Here is the Function: function expand(id) { for (var i = 1; i<=10; i++) { if (document.getElementById('smenu'+i)) { document.getElementById('smenu'+i).style.display='none'; } } if (id) { id.style.display='block'; } } The bit of code in bold in the code below is giving me this error in IE: Error: Code: Webpage error details User Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; Trident/4.0; Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1) ; SLCC1; .NET CLR 2.0.50727; Media Center PC 5.0; .NET CLR 3.5.30729; Tablet PC 2.0; InfoPath.2; OfficeLiveConnector.1.4; .NET CLR 3.0.30729; OfficeLivePatch.1.3; MSN OptimizedIE8;ENGB) Timestamp: Tue, 16 Mar 2010 15:07:11 UTC Message: HTML Parsing Error: Unable to modify the parent container element before the child element is closed (KB927917) Line: 0 Char: 0 Code: 0 URI: http://www.mateinastate.co.uk/users/mateinastate Code: Code: if(document.getElementById('msn1').innerHTML=="")

What it's saying isn't actually true (I don't think)... this is how the section is laid out: Code: <div id="submenu1" class="anylinkcss"> <ul> <li class="contact-pm"><a href="/index.php?do=pm&act=new&to=$RateViewProfileUserName$&returnurl=$ReturnURL$">PM me</a></li> <li class="contact-email"><a href="/index.php?do=email&id=$RateViewProfileUserId$">E-mail me</a></li> <li class="contact-msn" id="msn1">$RateViewProfileUser-profile_msn$</li> <li class="contact-yahoo" id="yahoo1">$RateViewProfileUser-profile_yahoo$</li> <li class="contact-skype" id="skype1">$RateViewProfileUser-profile_skype$</li> <li class="contact-facebook" id="facebook1"><a href="$RateViewProfileUser-profile_facebook$"><span id="fbook-add"></span></a></li> </ul> </div> <script type="text/javascript" src="/html_1/js/contact-information.js"></script> Does anyone know why this might error in just IE? Hi, I'm relativly new to JS and brand new to the forum so you might need to dumb down your replys for my slightly lacking knowledge. That being said I do have a very solid grasp of html, css and am getting there with JS and its various frameworks. I'm integrating wordpress into an existing site for a friend and currently have the main blog page appear in a DIV. This is the best way to integrate in this case due to many reasons mostly of way the site is constructed. Code: <div class="scroll-pane" id="scrollbox"> WORDPRESS BLOG </div> My issue is that links within that DIV, in the blog, when clicked redirect the page. The simple answer to this would be to have them just open in a new page, which I can easily do with the below code. Code: function Init()
{
// Grab the appropriate div
theDiv = document.getElementById('scrollbox');
// Grab all of the links inside the div
links = theDiv.getElementsByTagName('a');
// Loop through those links and attach the target attribute
for (var i=0, len=links.length; i < len; i++) {
// the _blank will make the link open in new window
links[i].setAttribute('target', '_blank');
}
}
window.onload = Init;
But what I'd rather it do is have any link clicked inside the DIV to reload in that same DIV, similar to an iframe, but obviously without using an iframe, due to it's compatibility issues. Is this possible by editing the above code? If not what do I need? Thanks in advance for any help! Hi, I am trying to figure out how the get the featured area at http://blueoceanportfolios.com to link to webpages rather than displaying it within the featured box on the left . This area is using JS file to display the videos on content in the featured box when different items on the menu are clicked, here is the working example : http://www.blueoceanportfolios.com/company/ Okay , The problem: Loading a new webpage rather than displaying the content at featured box at http://blueoceanportfolios.com Tried solutions: linking to javascript functions like onclick="window.location="http://someplace.com";" etc but still the content loads up in the featured box , try clicking on 2) it displays http://www.codingforums.com rather than loading new page. Any suggestions I have been testing regex test string to match the following pattern (- <any number with/without . decimal point>) ( -[#[.#]] ) here is the code that works the best: Code: var testStr = '99999+((-25.533) - 5)/99*(-25.533)';
var negValTestStr = new RegExp('\\(\-{1}[0-9]*\.?[0-9]*\\)', 'g');
var test = testStr.match(negValTestStr)
alert(test);
The question is: Why does it only work when the open and close parenthesis are double escaped: '\\(' and '\\)' When I use one backslash to escape, it will find -25.533, -5 and -25.533 With two backslashes for escape sequence: (-25.533), (-25.533) Also, I have to escape the - to get just one -. If I do not escape the -, -?; which should read - {0, 1} will match --# without escaping - Thanks for thoughts on this JK Hi everyone Im new here nice forum Hope someone can help out with my problem http://www.testingremote.ucoz.com/ When you click on anything other than home on the nav bar it messes up the appear/fade behavior that I added with dreamweaver any solutions ? Please help ! 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. Since it is not clear to me where this post should fit in the forum, I'm just posting it here. Is it possible to create a tracking code that would allow me to: (1) a) Find out the identity of visitors to a certain website (a website unrelated to me and the visitors did not visit my website) b) The identity of those who recently searched for a certain keywords and/or... (2) Find out what websites certain individuals have recently visited (or visiting in real-time)? Ok, so I wanted to use the following object to copy the contents of the Report array at index [file][entry]. Code: Selected = {
fileIndex : file,
entryIndex : entry,
Entry : Report[file][entry]
}
This was done so that the user may perform modifications to the entry without updating the entry until I have run validation on the input. Then I used Code: if(valid) Report[Selected.fileIndex][Selected.entryIndex] = Selected.Entry to finish up. I noticed that the Report array was getting the new input even when I didn't validate. I used the following to view all the contents of the Report Array in real time Code: window.setInterval('SHOW_ARRAY();',200);
Report=[];
function SHOW_ARRAY(){
HTML('ReportDebug','') //Reset "ReportDebug" HTML element
for(var t in Report){
for(var y in Report[t]){
for(var u in Report[t][y]){
HTML('ReportDebug','<span style="position:relative ; border:2px solid black">'+Report[t][y][u]+'</span>',1) // last argument signifies to append HTML element
}
}
HTML('ReportDebug','<br />',1)
}
}
And what I discovered was that whenever I stored values in Selected.Entry the Report array would update with those values! This is my first attempt to create an object in this fashion, so my only guess is that Selected.Entry is not independent from Report[file][entry], but instead some kind of pointer... Where have I gone wrong, and how can I accomplish my goal? Let me know if my code samples were too brief. hi i am using an image scroller and i have it on three pages, the pages use the same header, the same css and the same basic structure. such as table content footer the problem is that the scroller works fine on two of the pages but does not work at all on the one page. here is what i am getting on that page Code: Message: 'ElementExtensions' is null or not an object Line: 1898 Char: 3 Code: 0 URI: http://www.mysite.com/lightbox_slideshow/prototype.js Message: Object doesn't support this property or method Line: 705 Char: 41 Code: 0 URI: http://www.mysite.com/lightbox_slideshow/lightbox.js Message: Array length must be assigned a finite positive number Line: 464 Char: 5 Code: 0 URI: http://www.mysite.com/lightbox/js/prototype.js the only common denominator i can see is that the page it does NOT work on is in fact a photo manager page, the other two (that DO work dont deal with photos) i checked the array and the js vars and stuff are different from my photo manager vars (php) so i was thinking maybe there might be a clash of some kind accessing the queries at the same time when the page loads but i dont get any errors other than these. by the way the scroller is black not grey like the others for background. does it sound like from the errors that i am getting that it might be a db query clash of somekind or do you know anything about those errors above that might give me a clue whats going on. thanks I am attempting to implement a Close icon which responds to mouseover, mouseup, mousedown, and mouseout. The problem is that the first DIV I display, using this code, works as intended, i.e. all the button states work. I can close and reopen the same DIV and everything is still fine. If I open a second DIV, which uses the reuse code below, the button states do not appear, although the DIV will close properly. If I step through the debugger all of the state images load properly but do not appear. Once I have tried to use the button in the second DIV, all of the DIV's fail to display the button states but close properly. Additionally all of the pages where this is used are generated using XMLHttpRequest(). The DIV's using this are generated when the site loads and then shown and hidden as needed with their contents being generated via XMLHttpRequest(). Anyone have any ideas? The intent is to reuse the following in a number of DIV's: Code: rtn = "<div id='closepanel' class='closepanel'><img src='images/closebutup.png' name='closebut' width='20px' height='20px' border='0px' onmouseover=\"swapbuttonstate('closebut','over')\" onmouseout=\"swapbuttonstate('closebut','out')\" onmousedown=\"swapbuttonstate('closebut','down')\" onmouseup=\"closePanel('"+this.msDivid+"')\" ></div>";
On startup I preload the images using : Code: if (document.images) {
closebutup= new Image();
closebutup.src="images/closebutup.png";
closebutover= new Image();
closebutover.src="images/closebutover.png";
closebutdown=new Image();
closebutdown.src="images/closebutdown.png";
}
The swapbuttonstate function is defined as: Code: function swapbuttonstate(buttonname, state) {
switch(state) {
case "over":
if (document.images) {
butover=eval(buttonname + "over.src");
document[buttonname].src= butover;
}
break;
case "out":
case "up":
if (document.images) {
butup=eval(buttonname + "up.src");
document[buttonname].src= butup;
}
break;
case "down":
if (document.images) {
butdown=eval(buttonname + "down.src");
document[buttonname].src= butdown;
}
break;
}
}
and closePanel is defined as: Code: function closePanel(divid) {
document.getElementById(divid).style.display='none';
}
Any help would be greatly appreciated. Hi, I used the code on the following example: http://www.w3schools.com/php/php_ajax_livesearch.asp Instead of xml I use mysql but it works the same way. My problem is with this character '#' (shift 3 - on my keyboard, or otherwise known as 'sharp'). Some of the words in my database table contain this character but when I type it, it acts like nothing was typed. Any idea on what to do to make this work like any other character? Thanks have a look at this website. www.projectorhire.ie in the contactDetails div the number appears for a split second and then disappears.. it only happens in firefox.. Can anyone tell me what the prob could be? Hi! I couldn't find any information about this topic in the internet and I really wonder, how come people do not discuss it anywhere? Okay, jQuery works really great and offers many interesting effects, but what if you have JavaScript disabled? I mean I've browsed through several websites powered by jQuery with JS disabled and they doesn't work or behave weird. I know there aren't much people, who disable JS, but well I do want my page to be seen by all people in the end. I managed to do it with slider on my page (however I want to use other jQuery effects), but, for example, http://www.flowplaye...ools/index.html doesn't provide any information about this. Try to disable JS and see that nothing works. I can use <noscript></noscript> tag, but I have to make two main pages. And what if I want to view it on one page? What would you do? Regards, Aleks. |
