Popup blocked when created in jQuery ajax success callback

问题

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);
        }
    });

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.

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.

Your code returns these in firefox and chrome:

Firefox: "Firefox prevented this site from opening a pop-up window." Chrome: "Pop-up blocked"

To fix this issue just add async:false to your ajax call.

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

});

Just be careful that async:false will force javascript to wait for jQuery ajax result. It means it freezes javascript until ajax call is completed.

Firefox does popup blocking based on the event that causes the javascript code to run; e.g., it will allow a popup to open that was triggered from an onclick, but not one that was triggered by a setTimeout. It has gotten a little bit complicated over the years as advertisers have tried to circumvent firefox's popup blocker.

回答5:

You can still have the code in the success event but async will need to be false.

回答6:

Follow the method described in this post:

window.open without popup blocker using AJAX and manipulating the window.location

In a nutshell, the approach is:

Your code must be initiated by an onclick event.
Open a new window, perhaps initially with no content, with window.open --- and store a reference to the window so that you can use it later.
In the success callback from your AJAX operation, use window.location.replace to manipulate the URL of your already-open window with the desired URL.

 if you put async:true then you must do the following:

 var safariOP = window.open("https://www.myurl.com");  // DEFINE BEFORE AJAX CALLBACK 

 $.ajax({
    type: "POST",
    url: "MyService.aspx/ConstructUrl",
    data: jsonData,
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function(msg) {
      if(safariOP){
         safariOP.focus(); // IT'S OK ON SAFARI
      }
    },
    error: function(msg) {
        //alert(error);
    }
});

if you put async:true then you must do the following:

var safariOp = window.open("https://www.myurl.com"); //define before callback ajax contains url .
 $.ajax({
    type: "POST",
    url: "MyService.aspx/ConstructUrl",
    data: jsonData,
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function(msg) {
        //it's ok on safari
        safariOp.focus();
    },
    error: function(msg) {
        //alert(error);
    }
});

this works for me.

$(document).ready(function() {
        $('#myLink').on( "click", function() {
            var myNewTab = window.open('about:blank', '_blank');
            $.ajax({
                method: "POST",
                url: "ajax.php",
                data: { name: "John", location: "Boston" },
            })
            .done(function( msg ) {
                myNewTab.location.href = "google.com";
            });
        });
    });
