Timed popup with PhoneGap/Cordova InAppBrowser?


I'm using PhoneGap (Apache Cordova) with the InAppBrowser plugin (cordova-plugin-inappbrowser). In order to display a popup window, I'm using the following function:

function popup(url) {
  var win = cordova.InAppBrowser.open(url, "_blank", "location=no");
  win.addEventListener("loadstop", function() {
    var loop = window.setInterval(function() {
      win.executeScript(
        {code: "window.shouldClose"},
        function(values) {
          if(values[0]) {
            win.close();
            window.clearInterval(loop);
          }
        }
      );
    }, 200);
  });
}

What I really need is a function whose spec is:

function Popup(url, maxTimeToWaitIfResponseIsSlow)

Any ideas how to achieve this?


Solution

  • So I've found an answer after some research and testing. Here is the modified function, with "double defense" in the client side:

    function popup(url) {
      var elapsed = 0;
      var loadstopFired = false;
      var win = cordova.InAppBrowser.open(url, "_blank", "location=no");
      setTimeout(function() {if (!loadstopFired) win.close();}, 2000);
      win.addEventListener("loadstop", function() {
        loadstopFired = true;
        var loop = window.setInterval(function() {
          elapsed += 200;
          win.executeScript(
            {code: "window.popupStatus"},
            function(values) {
              if (values[0]=="closed") { win.close(); window.clearInterval(loop); }
              else if ((values[0]!="loaded") && (elapsed>2000)) { win.close(); window.clearInterval(loop); }
            }
          );
        }, 200);
      });
    }
    

    While the server side (the url called) looks like:

    ...
    <body onload="window.popupStatus='loaded';">
      ...
      <img src="close.png" onclick="window.popupStatus='closed';" />
      ...
    </body>
    ...
    

    Any comment appreciated.
