if you want to set the value based on text then use this else val('value') should work fine.

JavaScript

var text = data[0].Type;
          $("#ddlCustType option").filter(function () {
              return this.text == text1;
          }).attr('selected', true);

keep an alert box for text and see whether you are getting the Id or Text or undefined.

Solution 1

I think what you are looking for is this.

To get selected text:

JavaScript

$("#ddlCustType option:selected").text();

Or to get selected value:

JavaScript

$("#ddlCustType option:selected").val();
