jQuery endsWith for attributes

using jQuery, I'm trying to see if a random id ends 开发者_如何转开发with a certain string using the following pseudo code:

var node = $('#foobar');

if (node.attr('id').endsWith('bar')) {
 // do stuff
}

I know for node selection you can go $(id?='bar') , but I need something that works for $.attr().

Any ideas?

If you already have the desired object and therefore also have the id string as in your example, then this is just a question about matching something at the end of a string so you could just match the id string vs. a regular expression:

if (node.attr('id').search(/bar$/) != -1) {

}

Try this

if (node.filter("[id$='bar']").length > 0){
   //do stuff
}

<div id="foo-bar">asd</div>

if ($("div[id$='bar']")) {
 // do stuff
}
