Opening Popup from website without Popup Blocker c

2019-09-22 03:45发布

i have a strange query, i want to open a new window (a popup), when the browser/tab is closed using asp.net, Jquery, but i want to bypass the popup blocker which blocks the window, can anyone help me with this, how can i open a popup when user closes the browser/tab, or any other alternatives which can help me achieve the same. the main problem is i want to ignore the popup blocker. on one the SO Post

i read the below example could help:

jQuery(function($) {
  // This version does work, because the window.open is
  // during the event processing. But it uses a synchronous
  // ajax call, locking up the browser UI while the call is
  // in progress.
  $("#theButton").click(function(e) {
    e.preventDefault();
    $.ajax({
      url:      "http://jsbin.com/uriyip",
      async:    false,
      dataType: "json",
      success:  function() {
        window.open("http://jsbin.com/ubiqev");
      }
    });
  });
});

i replaced the click event with $(window).unload but that too didnt helped. the popup does not opens, but when i remove e.preventDefault(); the popup opens, but require the popup-blocker be enabled.

I don't think there's a way to go around pop-up blockers.

You should change the approach and try to open the content in a jQuery UI modal dialog box, instead of using an actual browser window popup.

You have to open the window inside the same function as the $.ajax, otherwise some browsers will still reject the popup.

jQuery(function($) {
  // This version does work, because the window.open is
  // during the event processing. But it uses a synchronous
  // ajax call, locking up the browser UI while the call is
  // in progress.
  $("#theButton").click(function(e) {
    // use success flag
    var success = false;
    e.preventDefault();
    $.ajax({
      url:      "http://jsbin.com/uriyip",
      async:    false,
      dataType: "json",
      success:  function() {
          success = true; // set flag to true
      }
    });
    if (success) { // and read the flag here
        window.open("http://jsbin.com/ubiqev");
    }
  });
});

This is the only reliable way to make sure the uriyip gets called AND popup a window when it's done loading; so it freezes the browser, too bad.

Popup blockers are designed to prevent this behavior.

I would suggest using a modal window instead of an actual browser window. I don't think that these get blocked because they are opened within the page itself.

As for the event... You could do something like...

window.onbeforeunload = function whatever() {
       //Do code here for your modal to show up.
 }

If you are just trying ot give a warning or something you could do

window.onbeforeunload = function showWarning() {
       return 'This is my warning to show';
 }
