问题描述

Google Chrome 似乎阻止了我通过 jQuery 创建的弹出窗口.经过一番调查，在 ajax 调用的成功事件中调用 window.open 似乎是一个问题.有没有解决的办法?我的 jQuery ajax 调用返回要打开的 URL.所以我有点卡住了.

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.

如果我将 window.open 放在 ajax 调用之外，它会起作用；但是，在内部(即在成功事件中)它被阻止了.我认为这与 CONTEXT 有关，但我不确定.

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.

这是我所拥有的:

     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);
        }
    });

推荐答案

只需在成功回调中打开新窗口即可:

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);
    }
});

请注意，您可能必须为此将 $.ajax 的异步选项设置为 false，否则可能会在收到响应之前评估 $.ajax 调用之后的代码.

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.
