JQuery postmessage mismatch

I am trying to use Ben Almans jquery postmessage to resize an iFrame. I more or less use his example with different servers and dynamic content.

I also posted a question on this site, but it may actually be too new.

I have a job sending messages as a cross domain, but resizing just doesn't work. I'm just retelling what I wrote as Toby here:

I can not get iFrame to resize sequentially in browsers. Is this a touch you've come across? I added a timestamp to know when each function is called, and its rather strange ...:
- Firefox works fine - the child page starts up to the parent page.
- Chrome 7 will expand, not shrink. Timestamp = child to parent
- IE 8 ... the parent runs to the child ...! and the iframe is incremented by 30, each click on the links.

Does anyone have any experience?

Adding two pages for link to code:
Parent

<html> <head> <script language="javascript" src="jquery-1.4.2.min.js" type="text/javascript"></script> <script language="javascript" src="jquery.ba-postmessage.js" type="text/javascript"></script> <script> $(function(){ // Keep track of the iframe height. var if_height, // Pass the parent page URL into the Iframe in a meaningful way (this URL could be // passed via query string or hard coded into the child page, it depends on your needs). //src = 'http://oslsrv03/cross_remote/cross_remote.htm#' + encodeURIComponent( document.location.href ), src = 'http://oslsrv01/crosstest/child_postmessage.html#' + encodeURIComponent( document.location.href ), // Append the Iframe into the DOM. iframe = $( '<iframe " src="' + src + '" width="100%" height="100" scrolling="no" frameborder="1"><\/iframe>' ) .appendTo( '#zshop' ); //alert(src); // Setup a callback to handle the dispatched MessageEvent event. In cases where // window.postMessage is supported, the passed event will have .data, .origin and // .source properties. Otherwise, this will only have the .data property. $.receiveMessage(function(e){ // Get the height from the passsed data. var h = Number( e.data.replace( /.*if_height=(\d+)(?:&|$)/, '$1' ) ); if ( !isNaN( h ) && h > 0 && h !== if_height ) { // Height has changed, update the iframe. iframe.height( if_height = h ); } console.log("beskjed mottat og høyden vi fikk er: " + h); var currentDate = new Date() console.log("tid parent: " + currentDate.valueOf()) // An optional origin URL (Ignored where window.postMessage is unsupported). }, 'http://oslsrv01' ); // And for good measure, let send a toggle_content message to the child. $( '<a href="#">Show / hide Iframe content - dette sender beskjeden til iframen.<\/a>' ) .appendTo( '#nav' ) .click(function(){ $.postMessage( 'toggle_content', src, iframe.get(0).contentWindow ); return false; }); }); </script> </head> <body style="background-color:orange"> <div id="nav"></div> <div id="test"> <div id="zshop" style="border: 3px solid red"></div> </div> dette er slutten </body>

Child

 <html> <head> <script language="javascript" src="jquery-1.4.2.min.js" type="text/javascript"></script> <script language="javascript" src="jquery.ba-postmessage.js" type="text/javascript"></script> <script> $(function(){ // Get the parent page URL as it was passed in, for browsers that don't support // window.postMessage (this URL could be hard-coded). var parent_url = decodeURIComponent( document.location.hash.replace( /^#/, '' ) ), link; // The first param is serialized using $.param (if not a string) and passed to the // parent window. If window.postMessage exists, the param is passed using that, // otherwise it is passed in the location hash (that why parent_url is required). // The second param is the targetOrigin. function setHeight() { $.postMessage({ if_height: $('body').outerHeight( true ) }, parent_url, parent ); //alert("barn sender beskejd og høyden som sendes er: " + $('body').outerHeight( true )); console.log("barn sender beskejd og høyden som sendes er: " + $('body').outerHeight( true )); var currentDate = new Date() console.log("tid child: " + currentDate.valueOf()) }; // Bind all this good stuff to a link, for maximum clickage. link = $( '<a href="#">Show / hide content<\/a>' ) .appendTo( '#nav' ) .click(function(){ $('#toggle').toggle(); $('#stor').toggle(); setHeight(); return false; }); // Now that the DOM has been set up (and the height should be set) invoke setHeight. setHeight(); // And for good measure, let listen for a toggle_content message from the parent. $.receiveMessage(function(e){ if ( e.data === 'toggle_content' ) { link.triggerHandler( 'click' ); } }, 'http://oslsrv03' ); //http://127.0.0.1 }); </script> </head> <body style="background-color:white;border: 3px solid black"> <div id="nav"></div> <div id="toggle"> nå fra oslsvr03 <div style="height:200px; background-color:blue;"></div> </div> <div id="stor" style="height:800px; background-color:orange; display: none">Denne skal ikke vises hele tiden!!!</div> </body>

Forgot to add doctype to iframed content. Now it works like a charm in my test case. A bit less charming in the real world script, but I'll see what I did goofed there ...
