How to write javascript on asp.net page

Question

How to write javascript code on asp.net page such as (input box) to get value in a better manner .... or another controls message boxes (alert,confirm,...... (please if you can, give me an example? )

the best option is to put all the javascript functions in a separate .js file and while deloying the application minify the .js and use it. — Aravind

@Aravind: minifying is sometimes just too overrated... at least you've got the browser cache :) if you'd really like to optimize, you'd better create one big file to minimize the requests! — user57508

@Andreas one cannot generalise it and have to deal with it on a case to case basis. — Aravind

@Aravind: neither you can... so throwing "MINIMIZE!" in is as stupid as my suggestion :) — user57508

as you would on a "normal" html page :)

you can enhance your scripts - no, sometimes you MUST - with eg.

<%= this.inputBox.ClientID %>

i would recommend jQuery for such enhancements ... its feature rich, easy to learn, ...

you could do eg.

var $inputBox = $('#<%= this.inputBox.ClientID %>');
$inputBox.hide();
var oldValue = $inputBox.val();
$inputBox.val('now it has no value');

.. and many more!

there are many tutorials on the net... to give a very rough overview, try this

You can use the ClientID property. Example

<img src="images\cal.gif" 
onclick="openCalendar(<% = txtDate.ClientID %>, 150, -150);return false;" />
