Introduction

Here I will explain how to get dropdownlist selected value or selected item text using JavaScript in asp.net.

Description:
  
In previous article I explained Fire Dropdownlist selectedindexchanged event  and many articles relating to JavaScript. Now I will explain how to get dropdownlist selected value using JavaScript in asp.net.

If we want to get dropdownlist selected value or selected item text in JavaScript we need to write the code like as shown below


<script type="text/javascript">
function GetCountryDetails() {
// Get id of dropdownlist
var parm = document.getElementById("ddlCountry");
// Get Dropdownlist selected item text
document.getElementById('lbltxt').innerHTML = parm.options[parm.selectedIndex].text;
// Get Dropdownlist selected value item
document.getElementById('lblid').innerHTML = parm.options[parm.selectedIndex].value;
}
</script>
If you want check this code in sample check below code

Example:

<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title>Get Dropdownlist selected value and text in JavaScript</title>
<script type="text/javascript">
function GetCountryDetails() {
// Get id of dropdownlist
var parm = document.getElementById("ddlCountry");
// Get Dropdownlist selected item text
document.getElementById('lbltxt').innerHTML = parm.options[parm.selectedIndex].text;
// Get Dropdownlist selected value item
document.getElementById('lblid').innerHTML = parm.options[parm.selectedIndex].value;
}
</script>
</head>
<body>
<form id="form1" runat="server">
