Open window and close immediately

In JS, there is a way to open a window and close it immediately so that it does not open in a new tab , I just want to open a window (for example, in the background, if possible) do some checking and close it immediately, without the effect of opening a new tab , maybe is it?

Something like this, but without opening the window ...

var popup = window.open("http://www.google.com"); popup.close();

UPDATE: Here is a solution that I found, but it sometimes changes, and I want to avoid it ...

 function goNewWin() { var TheNewWin = window.open("http://www.yahoo.com", 'TheNewpop', 'toolbar=1,location=1,directories=1,status=1,menubar=1,scrollbars=1,resizable=1'); TheNewWin.blur(); TheNewWin.close(); }

Your problem is window.postMessage() using the window.postMessage() function. child used to notify parent that the window has been loaded, and also works on cross domain .

Child

 $(window).load(function(){ this.opener.postMessage({'loaded': true}, "*"); this.close(); });

Parent

 $(window).on('message', function(event) { alert(event.originalEvent.data.loaded); });

There is also another method described in this stackoverflow thread.

Even if you call close immediately after window.open , and even if you try to find the pop-up window outside the screen or make it zero size, you will see that it quickly blinks on the screen:

 var popup = window.open("", "Popup", "left=10000,top=10000,width=0,height=0"); popup.close();

For security reasons, window.open cannot position the pop-up outside the screen and cannot make it smaller than the minimum. Here is a fragment of window.open in the MDN documentation :

The requested position and the requested measurement values ​​in the list of functions will not be respected and will be corrected if any of the requested values ​​does not allow the entire browser window to be displayed within the workspace for user operating system applications. No part of a new window can be originally placed off-screen. This is the default in all versions of Mozilla-based browsers.

Similar restrictions apply in Internet Explorer, as indicated in this document . The minimum size is 250 times 150 in Internet Explorer , and the minimum "internal" size is 100 × 100 in Firefox .

If you absolutely want to avoid the popup popup, you can use one of the following methods:

  • Instead of testing with window.open display a warning on the page to tell the user that the pop-up blocker should not be activated (as suggested here by UncaAlby)
  • Let the application start and warn the user after the fact if the real popup cannot be displayed
  • Use an alternative to window.open , for example, a dialog widget from the jQuery user interface or modals from Bootstrap

// The code for the page from which you want to open the popup window will open a small popup window in the lower right corner.

 var popup = window.open("popup.html", "Popup", "height=1, width=1, status=no, toolbar=no, menubar=no, location=no, top = 100000, left=100000 ");

// In your popup.html add follwing code

 this.close();

How about dynamically creating an iframe in the current window. Then you can open any page on it, later you can destroy the iframe element at any time.

If you don’t want the user to know that you have done some process at some URL, use the AJAX call and the process

or you do it

 <script type="text/javascript"> var popup = window.open("http://www.exampleurl.com/popup.html", "Popup", "height=10, width=10, status=no, toolbar=no, menubar=no, location=no, top = 1, left=1"); </script>

here in popup.html you can write code to close it.

This is an open window in stealth mode. not visible to user. Hope this helps you.

 window.open(path.html,'_blank','toolbar=no,status=no,menubar=no,scrollbars =no,resizable=no,left=10000, top=10000, width=10, height=10,visible=none', '');

I do not think that you can avoid the flickering of opening a new window. You can check the popup and save the state in a cookie. Then wrap your popup check in a simple if statement with the value of this cookie as logic. This avoids the popup checking that loads each page.

  var popUpCookie = "getCookie"; if(!popUpCookie){ var newWin = window.open("http://www.example.com"); if(!newWin || newWin.closed || typeof newWin.closed=='undefined') { //POPUP BLOCKED - Create Cookie }else{ //POPUP NOT BLOCKED - Create Cookie } }
