Popup blocked when created in jQuery ajax success callback

Question

Google Chrome seems to be blocking a popup I am creating via jQuery. After some investigation, it appears to be an issue with calling window.open in the success event of an ajax call. Is there a way around this? My jQuery ajax call returns the URL to be opened. So I am bit stuck.

It works if I place the window.open outside the ajax call; but, inside (i.e. in the success event) it is blocked. I think it is something to do with CONTEXT but I am unsure.

Here is what I have:

     window.open("https://www.myurl.com");  // OUTSIDE OF AJAX - no problems 
                                            // with popup

     $.ajax({
        type: "POST",
        url: "MyService.aspx/ConstructUrl",
        data: jsonData,
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function(msg) {
            // Normally loads msg.d which is the url returned from service
            // static url below is for testing
            window.open("https://www.myurl.com");  // THIS IS BLOCKED
        },
        error: function(msg) {
            // alert(error);
        }
    });

Answer 1

As several people have pointed out, the accepted answer no longer works. Based on the comment by aidiakapi, I used a workaround by first opening the window.

window.open("about:blank", "myNewPage");

Then doing the ajax business and in the done() function, open the page with that name.

window.open("/foo.html", "myNewPage");

This also doesn't matter if you do it async or not.

Simply open the new window in the success callback:

 $.ajax({
    type: "POST",
    url: "MyService.aspx/ConstructUrl",
    data: jsonData,
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function(msg) {
        window.open("https://www.myurl.com"); 
    },
    error: function(msg) {
        //alert(error);
    }
});

Note you might have to set $.ajax's async option to false for that, otherwise the code following the $.ajax call could be evaluated before the response is received.
