javascript - DOM Events - Progress Indicator for Iframe location change -

-

i looking solution show progress indicator when iframe page changes, but prior iframe loading completely.

there 100's of pages on stackoverflow going on differences between jquery ready(), javascript window.load, document.load, domcontentready, on('pageinit'...) , after reading differences on these various techniques i'm bit stuck on how accomplish trapping event within iframe.

so far have succeeded in capturing when iframe has changed once dom built. able detect when page load have sort of indicator/spinner in header.

this have far (capturing iframe change on onload):

..... <iframe id="rssid" src="http://feeds.reuters.com/reuters/oddlyenoughnews"    onload="blerg()" style="width: 800px; height:600px"/> ...... $(document).on('pageinit','#index', function(){       alert('pageinit');  //gets called on first load  }); $(document).on('pageinit','#rssid', function(){       alert('pageinit rssfeed'); //nothing happens. }); function blerg() {     var myiframe = document.getelementbyid("rssid");     myiframe.onload = func; };  function func() {    alert("changed"); }

it appear pageinit correct path have no idea on how trap within iframe. prefer not using jquery, i'm not sure possible without huge amounts of code.

one final: need use die("pageinit");

thanks million!
