Use jQuery to make an ajax post.
//ajax
$.ajax({
type: "POST",
url: "/object/update/",
data: ({ postData1: postData1Value }),
cache: false,
success: function (data)
{
if (data.Success) //requires Success to be part of the returned object
{
}
},
complete: function ()
{
},
error: function (data)
{
}
});
