Question

I want set result to variable from MVC controller method.

function someFunction(){ 
    var result;
    $.Ajax{    
        //??? 
    }
    return result; 
}

//In comparison to c++

int f() { //just! return result; }

P.S.: It is not async, it should be sync function call in order to return value to the function body.

Answer 1

set up a controller

public ActionResult Foo(){

return Content("Hello Anton");
}

set up the ajax request, remember to make it async:false, which is by default true, in order to return the value

function greeting(){
   var x= $.ajax({
            url:'/ControllerName/Foo',
            async:false,    
          });
   return x.responseText();
}

now you can call the function like

var v = greeting();
alert(v); //if every thing goes well you will see "Hello Anton"
