Question

I have a <div contenteditable="true> that I am trying to use to get text from users. I would use a simple <textarea>, but I need line-breaks and eventually lists and tables etc. I am trying to build something that is semi a rich-text editor, but not a full fledged one. I do not want to use a rich text editor.

I am trying to eliminate the attributes on <span> tags from the text that is typed into the <div contenteditable="true> . Is there a way to do that with Regexp? I was having difficulties coming up with a Regexp because I can’t figure out how to make it so that the string starts with <span and ends with > and any number of characters can be in between. Is there a way to combine that in one Regexp? I came up with /^<span >$/ but that does not work because there is no division between the two strings. Would something like this work: /^[<span][>]$/g?

Use DOM functions for it. Here’s some code using jQuery to make it easier and nicer to read:

$('#your-div span').each(function() {
    var elem = this, $elem = $(this);
    $.each(elem.attributes, function(i, attr) {
        if(attr) {
            $elem.removeAttr(attr.name);
        }
    });
});

However, in your case you might want to remove attributes not only from spans but from all elements unless the attribute is e.g. align or href.

So, here’s some JS for that: http://jsfiddle.net/ThiefMaster/qfsAb/1/

$('#your-div').children().each(function() {
    var elem = this, $elem = $(this);
    $.each(elem.attributes, function(i, attr) {
        if(attr && attr.name != 'href' && attr.name != 'align') {
            $elem.removeAttr(attr.name);
        }
    });
});
