Custom JavaScript examples

[Erwin van der Zwart]

Another nice custom Javascript feature: Back to startpage after x seconds when there is no user input:

The startpage will be automaticly linked to the first page of the visu that is loaded.

Paste this code into your custom Javascript and adjust time (SE_Timeout) if needed.

Code:

$(function() {
 
 // Back to Start after x seconds (in miliseconds)
 var SE_Timeout = 90000; // adjust this timer value if needed (90 seconds in miliseconds)
 var SE_Startpage = currentPlanId; // First page that is loaded
 var eventlist = 'vclick vmousedown vmouseout touchend';
 
 // Timer function no usage detected
 function No_Usage_Detected(callback, timeout, _this) {
   var timer;
   return function(e) {
       var _that = this;
       if (timer)
           clearTimeout(timer);
       timer = setTimeout(function() {
           callback.call(_this || _that, e);
       }, timeout);
   }
 }

 // Back to start function when timer elapsed
   var SE_Goto_Startpage = No_Usage_Detected(function(e) {
   if ( currentPlanId != SE_Startpage ) {
    showPlan(SE_Startpage);
   }
 }, SE_Timeout);
 
 // Add event listener to document to detect user input
 $(document)
 .on(eventlist, function() {
   SE_Goto_Startpage();
 });

 // Add event listener to all iframes to detect user input inside iframes
 $('iframe').load(function() {
   var iframe = $('iframe').contents().find('html');
   iframe.on(eventlist, function(event) {
    SE_Goto_Startpage();
   });
 });

});
