JavaScript - ...Dropdown list in jqery.

Asked By shah zeb on 25-Nov-11 07:15 AM
I need an example in jquery in which,
there should be a dropdownlist list loaded from through jquery.
On selecting a value from the dropdownlist. It should add the value to a textbox.
When reselecting value it should populate values other than the selected values and so on...
Any or a short demo is required.


Regards,
shah

Try this to get the selectedValue

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

Try this:


$("#myselect :selected").text();


For an ASP.NET dropdown you can use the following selector:


$("[id*='MyDropDownId'] :selected")

It works But my main question was,
When i reselect values from the dropdownlist it should select only those values that are not already selected.
Example
drop downlist shows A , B  and C.
if i select B and then reload it should only show  A and C.
This is the main question.

    success: function(msg) {
      $("#ddlGender").get(0).options.length = 0;
      $("#ddlGender").get(0).options[0] = new Option("Select gender", "-1");  
  
      $.each(msg.d, function(index, item) {
        $("#ddlGender").get(0).options[$("#ddlGender").get(0).options.length] = new Option(item.Display, item.Value);
