Getting custom tag value using jquery

Question

<select id="selTest"> <option custom="123" value="abc">111</option> <option custom="456" value="def">222</option> <select> 

... using jQuery, how do I get option.custom where option.value = selTest.val ()

In other words: if selTest.val = def, then $ x = 456 (I'm trying to get the custom value in $ x)

Answer 1

Try the following:

 var selectedCustomValue = $("select#selTest option:selected").attr("custom"); 

Answer 2

 var selectElement = $("#selTest")[0]; alert(selectElement.options[selectElement.selectedIndex].getAttribute("custom")); 

Answer 3

Try to execute

 $('#selTest').change(function() { var value = $(this).val(); var custom = $('option[value="' + value +'"]').attr('custom'); ... });
