Preselect html select/drop down value based on text in


In this article I am going to explain about how to preselect asp drop down or html select value based on a text.


In some cases we are in the situation to preselect the drop down or html select option based on some text. Here I am explaining this process using javascript code. For the explanation purpose I have a form. In that form I have a html select with id “select_cities”. This select have three options and each option have some values. In this scenario I am supposed to select the option with the text “Kanna”. For this I have written a javascript function “test”.Below is the code used.


<%@ PageLanguage=”C#”AutoEventWireup=”true”CodeBehind=”Default.aspx.cs”Inherits=”WebApplication1._Default”%>
<!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Transitional//EN” “”>
<html xmlns=””>
<head runat=”server”>
    <form id=”form1″ runat=”server”>
        <select id=”C”>
            <option value=”0″>select name</option>
            <option value=”1″>kanna</option>
            <option value=”2″>dasan</option>
    <script type=”text/javascript”>
        window.onload = test;
        var name = “kanna”;
        function test() {
            for (var i = 0; i < document.getElementById(“select_cities”).length; i++) {
                if (document.getElementById(“select_cities”).options[i].text == name) {
                    var a = document.getElementById(“select_cities”).options[i].value;
                    document.getElementById(“select_cities”).value = a;
In the above code the javascript function through the for loop first gets the option value of that particular  text. After that set the options value to that value.
