jQuery selector comparing element's attributes (and/or properties) between them

Question

The thing starts from my previous question: Using jQuery is it possible to compare two attributes in a selector? I mean something like:

$(\'element[atribute1!=at         


        

Answer 1

No. If you look through jQuery's documentation, you'll see there's no such selector.

Also defaultValue is a property, not an attribute.

You can do this:

var changed = $('input').filter(function() {
    return this.value !== this.defaultValue;
});

Answer 2

You can use the jQuery filter() function, like this:

var different = $('input').filter(function()
{
    return $(this).attr('data-default-value') != $(this).val();   
});

Then, you can test different.length > 0.
