if i have something that looks like this ...

main.html
<body>
  <div id='sample' style='height:100px';>Sample Content</div>
  <div id='loadObj' style='height:150px';></div>
</body>
<script type='text/javascript'>
  $(document).ready(function(){
    $('#loadObj').load('load.html');
  });
</script>

Open in new window


load.html
<body>
  <div id='mainObj'>Loaded Content</div>
</body>
<script type='text/javascript'>
  $(document).ready(function(){
    var h = $('#loadObj').height();
    $('#mainObj').css('height',$('#loadObj').height()+'px');
    alert(h); 
  });
</script>

Open in new window


This wont work. The loaded doc seems to have it's own, separate DOM. In this scenario, the alert would be null. Why ? And how do I get around it.

I'm working on a project, and it relies pretty heavily on ajax & loading documents. This is causing problems for me in a handful of locations ...

Please help Experts - Thanks !!!

try removing body tag and make it

<div id='mainObj'>Loaded Content</div>
<script type='text/javascript'>
    var h = $('#loadObj').height();
    $('#mainObj').css('height',$('#loadObj').height()+'px');
   //alert(h);
</script>

check this then

make main.html as

<body>
  <div id='sample' style='height:100px';>Sample Content</div>
  <div id='loadObj' style='height:150px';></div>
</body>
<script type='text/javascript'>
  $(document).ready(function(){
    $('#loadObj').load('load.html', function(){
         $('#mainObj').height( $('#loadObj').height() );
    });
  });
</script>

load.html should be simply
<div id='mainObj'>Loaded Content</div>

what about :
<body>
  <div id='sample' style='height:100px';>Sample Content</div>
  <div id='loadObj' style='height:150px';></div>
</body>
<script type='text/javascript'>
  $(document).ready(function(){
    $.get('load.html', function(page) { $('#loadObj').html(page); });
  });
</script>

Hey Leakim, been a while since I've gotten one of your responses ... Maybe I'm actually learning & asking less questions these days !!?? lol

That worked out, but I ended up just kind of embracing what I was viewing as a problem.

I'm keeping the code separate on the loaded pages intentionally at this point, it's helping to keep the code much more organized, and i'm also only loading functions that relate to the body content at hand. My main functions.js is getting rather lengthy, so by keeping the code at the footer of the loaded pages, its keeping functions.js short - I'm only putting site-wide generic code in there, while I put the page specific code on each page.
