Sure. Give an Id to the submit button so that we can use that for jQuery selection later.
<input type="submit" id="ajaxSubmit" value="Add">
Now in javascript, listen for the submit button click and get the form and serialize it and send it to your action method.
$(function(){
$("#ajaxSubmit").click(function(e){
var _this=$(this);
e.preventDefault();
var _form=_this.closest("form");
$.post("@Url.Action("Create","User")",_form.seriazlize(),function(result){
//do something with the result
});
});
});
Assuming your action method parameter is good to receive the serialized form.
