Question

I don’t how to resolve this situation. I have this first dropdown menu with ID = PK1. I will force it to some value which goes off with cgi.perl and alters the second drop down menu with ID=#PK1_DEVICE_NAME_SELECTION based on some mysql lookup.

My coding below to force the val(‘$TEMP{DEVICE1_NAME}’) doesn’t work!

If I put an alert between the middle these 4 lines, it works. How do I resolve this?

                // FORCING VALUES FOR THE DROP DOWN MENU 1
                \$("#PK1").val('$TEMP{PDK1}');
                \$("#PK1").trigger('change');

                \$("#PK1_DEVICE_NAME_SELECTION").val('$TEMP{DEVICE1_NAME}');
                \$("#PK1_DEVICE_NAME_SELECTION").trigger('change');

Put it in your ajax callback. Something like this:

$("#PK1").val('$TEMP{PDK1}');
$("#PK1").trigger('change');

$('#PK1').change(function(){
    $.ajax({
        url:'whatever.cgi',
        success:function(data){
            $("#PK1_DEVICE_NAME_SELECTION").val('$TEMP{DEVICE1_NAME}');
            $("#PK1_DEVICE_NAME_SELECTION").trigger('change'); 
        }
    });
});
