You can try like dis

Var data=$("input[id*=ddlPortfolioName]").val();

alert(data);

or

alert($('#<%= ddlPortfolioName.ClientID %>').val());

or if its in child page..den u hv to pass the server side ID..for example my server side id is

alert($("#ctl00_MainContent_ddlPortfolioName").val());

You need to select selected option and then get its value.use:

$('#<%=ddlPortfolioName.ClientID %> option:selected').val()

Simply use ID Selector (“#id”) you do not need attribute selector with wild card if you have only one item to get. As ClientID gives you complete and exact id of element.

alert($('#<%= ddlPortfolioName.ClientID %>').val());

If you are using framework 4 or above you can use Control.ClientIDMode to keep the Server id as ClientID

alert($('#ddlPortfolioName').val());

If you have dropdown in grid or repeater or listView then you will have to use contains wild card with attribute selector.

 $('[id*=ddlPortfolioName]').each(function(){
       alert($(this).val());
 });
