MVC jQuery submit form (without page refresh) from JavaScript function

Is that Ajax.BeginForm that you need to use, not Html.BeginForm ?

This is how I do that with jquery:

function DoAjaxPostAndMore(btnClicked)
{
       var $form = $(btnClicked).parents('form');

        $.ajax({
            type: "POST",
            url: $form.attr('action'),
            data: $form.serialize(),
            error: function(xhr, status, error) {
                  //do something about the error
             },
            success: function(response) {
                 //do something with response
                LoadBooks();

            }
        });

  return false;// if it's a link to prevent post

}

I assumed that btnClicked is inside of the form:

<input type="button" value="Submit" onclick="DoAjaxPostAndMore(this)"/>

if link:

  <a href="/url/something" onclick="return DoAjaxPostAndMore(this)">linktext</a>

If link is not inside for the form you just have to use jquery selectors to find it. You may set id to the form and then find form like this:

var $form = $("#theformid");
