javascript - Add class to selected div (div is not unique) -

i have different divs have id="item". when select 1 of divs, new class should added a div has been selected. there way when ids not unique?

html:

<div class="something" id="item">    <a href="#" class="something">...</a> </div> <div class="something" id="item">    <a href="#" class="something">...</a> </div> <div class="something" id="item">    <a href="#" class="something">...</a> </div> <div class="something" id="item">    <a href="#" class="something">...</a> </div> 

javascript (what have tried, not work):

// changes links on website $("body").delegate('#item', 'click', function() {       $( "a" ).addclass( "active" ); }); 

edit: using delegate function because create divs php, otherwise click event not registered.

don't ever have non-unique id, not valid. invalid ids aside, not working since using $("a") targets links, rather specific one.

html:

<div class="something" id="item1">    <a href="#" class="something">...</a> </div> <div class="something" id="item2">    <a href="#" class="something">...</a> </div> <div class="something" id="item3">    <a href="#" class="something">...</a> </div> <div class="something" id="item4">    <a href="#" class="something">...</a> </div> 

js

// doubt actual site uses in both cases, // made more explicit. $("body").on( 'div.something', 'click', function() {        $('.active').removeclass( 'active' );      // use add active div     $( ).addclass( "active" );      // use add active link     $( ).find( 'a' ).addclass('active");  }); 

also note changed delegate on assuming using latest version of jquery - if not go delegate
