Question

I have an attribute which might look like this abcjQuery12345, these numbers are just an example.
Is there a way to determine an attribute which contains a substring in jQuery?

E.g. abcjQuery12344353452343452345="12"

The only thing I know is that the attribute will contain abc.

You can loop through all the attributes and check if they contain the string you are looking for. With:

​<div customAttr="12" title="me"></div>
<div anotherAttr="Bear"></div>
<div yetAnotherAttr="Elephant"></div>

You could use:

var m = /another/i; //will look for 'another' in the attribute name (i-flag for case-insensitive search)

$('div').each(function(){
    var $this = $(this);
    $.each(this.attributes,function(){
        if (this.name.match(m)){
            $this.addClass('selected'); //either select the matching element
            $this.text(this.name + ' : ' + this.value); //or use its custom-attribute's value
        }
    });
});​
