Compare two dropdowns in ASP.NET

[ganeshshegde]

Hi,
How can i compare values of two dropdown lists in .aspx page using javascript?

I used following code-
[code=javascript]

function ValidateFlightR equest()
{
var vFromCombo = igcmbo_getCombo ById("ctl00_Sea rchBar1_ddlLeft searchFrom");

var vToCombo = igcmbo_getCombo ById("ctl00_Sea rchBar1_ddlLeft searchTo");

if(vFromCombo.g etSelectedIndex () == vToCombo.getSel ectedIndex())
{
alert("From Airport and two airport cann't be same");
return false;
}
}[/code]

Hi Ganeshshegde!
Welcome to theScripts, I hope you like it here!

Why would you want to do this using JavaScript?
Please note that people can easily by-pass JavaScript checks and submit invalid data to mess up your program.

Anyways, I would do this check server side on button click.
If it the arports match you could just set an error message in a label instead of using a JavaScript alert box.

Is it absolutely necessary to use JavaScript for this?
