I want to be able to disallow images (and other stuff) from being dropped into a content editable div across browsers. I see how to do it for Chrome and IE. Firefox stubbornly refuses. The code snippet at http://jsbin.com/oqozo3 has an example which shows that the event is firing, I am cancelling it, and in Firefox the image still appears.
Basically, The following fails to work in Firefox:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>ContentEditable fails in FF</title>
<script type="text/javascript">
function init() {
var target = document.getElementById("target");
if (target.addEventListener) {
target.addEventListener ("dragenter", all, false);
target.addEventListener ("dragover", all, false);
target.addEventListener ("drop", all, false);
target.addEventListener ("dragdrop", all, false);
} else {
target.attachEvent ("ondragenter", all, false);
target.attachEvent ("ondragover", all, false);
target.attachEvent ("ondrop", all, false);
}
}
function all(event) {
if (event.preventDefault) { event.preventDefault();}
return false;
}
</script>
</head>
<body onLoad="init();">
<div id="target" style="border: 1px solid black; height: 100px;" contenteditable="true">This is editable content</div>
<div>
<p>I don't want the image to be draggable to the above div. Works in IE,
Chrome, not firefox.</p>
<img src="http://mozcom-cdn.mozilla.net/img/firefox-100.jpg">
</div>
</body>
</html>
I have already looked at: ContentEditable DIV - disabling drag and drop, but the suggestions there also don't work in Firefox.
