DOM - More than 5 'window' objects on one page

I'm trying to extract data from o开发者_Python百科ne of my websites using Greasemonkey. Problem is, the script runs 6 times because apparently the page loads content from 6 different servers.

So if I put in an alert ("Hey"); the code runs 6 times and I get 6 alerts.

How can I wait for the entire page to load and then start playing with the DOM. Also, I'm using jQuery.

Thanks

Do you mean that the page is loading other pages via iFrames? as far as I know that is the only way that what you explain can happen.. So if that is true, try:

(function(){
  //ignore any window/iframe that is not the top window
  if(window.parent != window) return;

  // the main function
  var mainFunction = function(){
    alert("Hey");
  }

  if(document.readyState=="complete"){
    // for google chrome
    mainFunction();
  }
  else{
    // wait until the load event
    window.addEventListener("load", mainFunction, false);
  }
})();
