Server Side Calling Method From Javascript

[khKamel]

Hello, When i want to call a server side from javascript i used to use the alert('<% MethodName() %>') which returns a specific string. Now i want to apply this in Jscript.js File which can't be done. My question is how could i use that type method calling from a js file. Please note that the method is found a another place such as (Master Page) Many Thanks

By using <%= MethodName %> you are not really using JavaScript to call the server, this is done by ASP.NET while processing the page, this is why it only works in an ASP.NET page and not from an external file.
