How to Access of hiddenfield value in external .js file

Question

Hi,

 

I have a asp hidden field on my web form. I set the hidden field value from the code behind. I want to access this value from a javascript function in external .js file.

 

This is the asp hidden field

 

 

I set the value in code behind

 

HiddenField1.Value = "xyz";

 

How can I access HiddenField1.value in external .js file.

 

Give me example...

 

Thanks
