jquery to select a dropdown list control in asp.net

Question

I am using ASP.net and have a dropdown control.

 <asp:DropdownList runat="server" ID = "fieldReadOnlyContent" Enabled="false" class = "attribute"><asp:ListItem value = "0">False</asp:ListItem><asp:ListItem value = "1">True</asp:ListItem></asp:DropdownList>

I wanted to adjust the dropdown control via the clientside controls qith jquery. I get the value which it needs to be set to.

//d[3] will be either true or false.
$("#fieldReadOnlyContent").val(d[3]);

the above attempt didnt seem to set the item to properly enabled. HOw would i do this?

Try this:

$("#<%=fieldReadOnlyContent.ClientID%>").val(d[3]);

this will work but you will no longer be able to dynamically add/modify controls onthe page, if that where required...

The item is not getting set because $("#fieldReadOnlyContent").val(d[3]); will check for the value.

For your case

if(d[3]=='false'){
 $("#fieldReadOnlyContent").val('0');
}
else
{
 $("#fieldReadOnlyContent").val('1');
}

@Fallenreaper : No issues. I had got into the same problem a week ago. Hence I knew what was the issue

fieldReadOnlyContent is not necessarily the ID given to the client-side HTML element.

You can use ClientIDMode="Static" server-side to control the client-side ID in .net4.0 (source), or <%= fieldReadOnlyContent.ClientID %> to inject the client id directly into the javascript otherwise.
