There are some issues that are unclear in your question.
1) What do you mean when you say "Screen is clicked" ?
- Anywhere in the open browser window?
- Anywhere in the open browser window including the iframe?
2) Is your IFRAME 100% of the width and height of the browser window?
Regardless, below I break down your problem and hopefully give you a solution...
How do we refresh a webpage?
You can refresh a webpage using:
location.reload(true);
How do we refresh an iframe?
You may refresh an IFRAME using the code here:
Refresh an iframe
<iframe id="myiframe" src="http://google.com"></iframe>
document.getElementById("myiframe").src = "http://www.google.com?"+(+new Date());
How do we detect the click?
You can use the solution here:
https://stackoverflow.com/a/2622026/1688441
document.onclick= function(event) {
// Compensate for IE<9's non-standard event model
//
if (event===undefined) event= window.event;
var target= 'target' in event? event.target : event.srcElement;
alert('clicked on '+target.tagName);
};
Remaining issues:
What happens if user clicks within IFRAME?
If the user clicks within the IFRAME, and we control the code of the IFRAME we can have a click listener within the HTML/JAVASCRIPT of the IFRAME and trigger a refresh.
If we have different domains, due to security reasons there is not much that can be done.
