等待__doPostBack（）函数完成

Question

I don't have the source code of a web application in .Net neither the access to the database.

And with Greasemonkey I use JavaScript.

In the source code of HTML I have :

<input ... onclick="javascript:__doPostBack('ctl00$MidContent$GridView4','Page$10')">

So in greasmonkey script I put

__doPostBack('ctl00$MidContent$GridView4','Page$10');
/* others instructions */

But the others instructions doesn't wait the __doPostBack() function to complete.

I want nothing to execute until the __doPostBack() have not finish.

PS: I'm not good at .NET just with JavaScript

This is a good way:

$.ajax({
        type: "POST",
        data: 
        {
            '__EVENTTARGET': '<%=YourButtonName.ClientID %>'
        }
    }).done(function (data) {
        alert("ok");
    }).fail(function (p1, p2, p3) {
        alert("error");
    });
