After the AJAX request succeeds, window.open () is handled by the browser blocker pop-up window

I have been using window.open (URL) to open a new switch card loading page, and I found this situation when I used the Opera browser test today.

The first thought was window.open () browser compatibility issues, so try a-tag click, Form form submission, and window.open () to add "_blank" parameter of the way not.

Later, it might be a question of the AJAX request callback. Finally, Baidu told me a solution, as follows.

Workaround:

1, asynchronous to synchronous, that is: Async:false

2. Point the new window to an object, and then modify the object's URL, for example:

$ ('. Task '). bind (' click ',function() {    var w = window.open ();    $.ajax ({        ' POST ',        '/surveytask '        ,        ' json ',function  () {            w.close ();        },        function(res) {            = res.url;        }    

After the AJAX request succeeds, window.open () is handled by the browser blocker pop-up window
