How to get selected value of Kendo DropDownList in jQuery?

Kendo UI is a popular JavaScript framework that provides a wide range of powerful widgets for building modern web applications. One of the commonly used widgets is the DropDownList, which allows users to select a single value from a predefined list of options. In this article, we will discuss how to retrieve the selected value of a Kendo DropDownList using jQuery.

How to get selected value of Kendo DropDownList in jQuery?

To get the selected value of a Kendo DropDownList in jQuery, you can use the following code:

“`javascript
var dropdownlist = $(“#myDropDown”).data(“kendoDropDownList”);
var selectedValue = dropdownlist.value();
“`

The code above demonstrates how to retrieve the selected value of a Kendo DropDownList using jQuery. We first use the jQuery selector `$(“#myDropDown”)` to select the DropDownList by its ID. Then, we use the `data()` method to retrieve the DropDownList widget instance. Finally, we call the `value()` method on the widget instance to obtain the selected value.

Let’s take a closer look at the code:

– `$(“#myDropDown”)` is the jQuery selector that targets the DropDownList. Make sure to replace `”myDropDown”` with the ID of your DropDownList element.
– The `data(“kendoDropDownList”)` method is used to retrieve the DropDownList widget instance. This will allow us to access the methods and properties specific to the widget.
– `value()` is a method provided by the Kendo DropDownList widget. It returns the selected value as a string.
