How to reset Asp.Net DropDownList or HTML dropdown using jquery

jQuery to reset Asp.Net DropDownList or HTML dropdownIntroduction:  In this article I am going to explain with example How to reset or clear dropdownlist or html dropdown selected value to set it back to its initial/default state using jquery.

Description: We all know that in we can clear dropdownlist using the server side code i.e. DropDownList1.ClearSelection() method. Same functionality can be achieved at client side using jquery very easily. There are a number of ways to reset dropdown list back to default state. I am going to share some of them through this short article.

First Method

Set the value of DropDownList to 0 which is the first item in our list. 

If the value of first item in dropdownlist is 1: 

If the value of first item in dropdownlist is -1 :

If the value of first item in dropdownlist is “—Select--” :

Second Method

Set the very first item of the list as selected.
If using 1.6 or higher version of jquery

$('#ddlMonths').find('option:first').prop('selected', 'selected');
$('#ddlMonths').find('option:first').prop('selected', true);

If using lower than 1.6 version of jquery

$('#ddlMonths').find('option:first').attr('selected', 'selected');
$('#ddlMonths').find('option:first').attr('selected', true);

Third Method

Set the very first item of the list as selected.
If using 1.6 or higher version of jquery

$('#ddlMonths option:eq(0)').prop('selected', 'selected');
$('#ddlMonths option:eq(0)').prop('selected', true);

If using lower than 1.6 version of jquery

$('#ddlMonths option:eq(0)').attr('selected', 'selected');
$('#ddlMonths option:eq(0)').attr('selected', true);

Fourth Method

Set SelectedIndex of DropDownList to 0, which is the first item in our DropDownList 

$('#ddlMonths').get(0).selectedIndex = 0;

Implementation: Let’s check these methods by implementing it.
