hi,Can anyone tell me how to return a variable from a jquery function in view to controller?
for example this is what i have written in my view file :

Code:

[removed]

var i=0;

$("button").click(function () {
         myFunction();
         alert(i);
         [b]return i;[/b]             [i]how to return this i variable to controller[/i]  
    });

function myFunction()
{    
    i++;
    $("button").after('<input type="text" name="n"/>',i);
}
