I need to select all elements have "user" word in their ID.

in attribute I will do it by $= but how can I do it by element ID?

You want something like this

$('[id*="user"]')

selects all elements

[id with an id

*="user" that contains user

Example: http://jsfiddle.net/jasongennaro/QXGen/2/

Here is more info on the attribute contains selector: http://api.jquery.com/attribute-contains-selector/

You'd do it with the use of the *= selector:

$('[id*="user"]').doStuff();

---

Use the contains variant of the named attribute selector with the id attribute.

$('[id*="user"]')...

---

An attribute selector like $('[id*="user"]') will match elements with the id 'user', 'users', 'superuser', 'abusers', 'user-details', etc.

If you had a more rigid structure for your IDs and wanted to only match things like 'user' and 'super-user' etc., you could try something like:

var userWordTest = RegExp("\\b" + "user" + "\\b");
$('[id]').filter(function() { return userWordTest.test(this.id); })
