attr help

[Troy Clemons]

i am trying to disable a drop down list control

here is the code

$("#payment").attr('disabled', 'disabled');

this does not seem to happen at all

here is the payment control

<label for="payments">Payment Type:&nbsp;&nbsp;&nbsp;</label><input id="payment" data-bind="value: payment" name="payment" />

and the code load the datasource

$.ajax({

                                url: 'dsr.asmx/get_Payment',

                                async: true,

                                cache: false,

                                timeout: 30000,

                                contentType: 'application/json; charset=utf-8',

                                data: "{}",

                                type: 'POST',

                                dataType: 'json',

                                success: function (msg) {

                                    $("#payment").val("revpay").kendoDropDownList({

                                        index: 0,

                                        optionLabel: "Select Payment Type",

                                        dataTextField: "Description",

                                        dataValueField: "Code",

                                        filter: "contains",

                                        suggest: true,

                                        minLenght: 1,

                                        change: onPayChange,

                                        dataSource: {

                                            data: msg.d

 

                                        }

                                    });

                                }

                            });

and the function to disable the control by another drop down list choice

function onResChange() {

               var res = document.getElementById("result").value;

               switch (res) {

                   case 'c':

                       alert('Canceled');

                       $("#payment").attr('disabled', 'disabled');

                       break;

                   case 'cb':

                       alert('Call Back no Sale');

                       break;

               }

           }

the alert's work but the .attr is never firing

i found it under the documentation for the drop down list under configuration

Drop Down List Configuration

here is the answer

var dropdownlist = $("#dropdownlist").data("kendoDropDownList");

// disable the dropdown

dropdownlist.enable(false);
