JQuery: How To Detect If Popup Window Is Closed?

I want to detect if the user pressed the browser's close button on a popup window in my application. By searching around I found this solution: $(window).bind('beforeunload',

Solution 1:

Can you try this, You can use the below code to check the browser popup closed status.

var yourwindowname; // add in Global    

/*Added this for to open a browser popup window */ 
if(yourwindowname==undefined){
    var param= "toolbar=no,scrollbars=1";
    yourwindowname=window.open("your url here", 'yourwindowname', param);
}else{
    yourwindowname.focus();     
}

/* Added this to Check the popup closed status - In your case on ajax success event  */
var timer = setInterval(function() {   
    if(yourwindowname.closed) {                             
        clearInterval(timer);  
        //do your process here
        alert("Popup Closed");
    }else{
       yourwindowname.close();
    }  
}, 1000); 

Updated code for your working project: Use the below code instead of your current javascript functions.

function popup (url) {          
    if(win==undefined){
        win = window.open(url, "Fenster",    "width=1200,height=600,resizable=yes,menubar=no,toolbar=no,status=no,location=no,directories=no"); 
    }else{
        win.focus();
    }       
    return false;
}

function checkWindowClosed(){
    var timer = setInterval(function() {
        if(win.closed) {
            clearInterval(timer);
            progress();
            alert("Popup Closed");
        }else{
            win.close();
        }
    }, 1000);
}

  $.ajax({
        type: "POST",
        url: "acquisition_cleanup.php",
        data: dataStr,
        success: function () {
            checkWindowClosed();
        }
    });
