How to get control value on home page using jQuery?

I have hidden field control in MasterPageand I want to get the value of hidden field control using jQuery on a page using MasterPage.

I have the following javascript that gets called if the hidden field on the page has a value:

if(!$('input[type=hidden]').val().length == 0 ) { }

What kind of javascript will I need to check the value of the hidden field in MasterPagefrom the page?

There is no difference between your page and the main page. Both of these concepts are at your ASP.NET level, and the browser simply receives one HTML document.

The master page simply displays with the child page as one HTML code, so you just have to access it on the client side as usual.

Try rewriting this:

if(!$('input[type=hidden]').val().length == 0 ) { }

and

if ($('input[type=hidden]').val()) {}

which is a simpler condition if the hidden field matters. I'm not sure if !combined with ==does what you want it to perform logically. In any case, $('input[type=hidden]').val()a more readable IMO.
