Please follow below any item:

1. Write a function in code behind with public/protected modifier and then call as below:

<%= YourCodeBehindFunctionName() %>

2. If you want to call a function from your business layer then call the function as, the function must be static:

<%= NamespaceName.ClassName.YourFunctionName() %>

in your function (with the one in javascript)

function alertMe() {
var box = document.getElementById("myTextBox");

<%=nameOfTheFunction()%> //this function is in your c# side which you wanted to call.
}

This is simple and usefull to call a c# side function in your javascript.

Not able to call..it says 'name 'functionname' does not exists in the current context.'
I tried but failed :-)
