How to pass the params value through ajax ?

Answer 1

Something like this.. Let me know if further guidance is needed..

var request= new XMLHttpRequest();
        request.onreadystatechange= function(){
             if (request.readyState == 4 && request.status == 200) {

             }
        };
        request.open("POST", "/home", true);
        request.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
        request.send("userAction=loadHomePage");
    };

To set the model object:

    var formData= new FormData();
    formData.append('username' , 'payal');
    formData.append('id' , 123456);
    request.send(formData);
