    <p>I'm implementing an infinite-scroll, which means I'm appending chunks of content into the DOM (via jquery and javascript).</p> <p>To make this feel smooth for the user, we need to do some manual scrolling to keep the content window "in the same place", especially as we prepend text in front of what the user is seeing. To accomplish this (prepend a chunk, then scroll the content down by the exact amount we prepended) we need to be able to determine the HEIGHT of the content we just prepended. This is where Firefox and IE differ. Firefox handles this correctly, and scrolls to the correct place in my content, but IE is reporting about 600px as the height when the true value is around 2400px. </p> <pre><code>var h1 = $(document).height(); //take the height before appending $('#textChunks').prepend(newContent); // prepend stuff on top var h2 = $(document).height();//take the height again... alert(h2-h1); </code></pre> <p>The alerted value is consistently wrong in IE (off by a factor of 3), and it's consistent no matter how I take the measurement (I could instead measure the height of the 'newContent' after it's in the DOM and IE still reports it wrong, but consistently). Even other 'built in' javascript functions such as .scrollIntoView() seem to be off by exactly this amount in IE. </p> <p>As a sanity check, I can create a stand-alone html file on my desktop with a sample of my content, and in this situation it works. So the problem seems to be only with content added after the pageload. </p>

    1. COFor what it's worth, it sounds like you have a css issue where the box module is shorter. Another issue could be a missing closing tag, or, well there is no code so 50 places to guess. I'd be left wounding why there was such a dif in value and that may be cause your css is not correctly accounting for the box module in borwsers that don't auto correct for you. Just a thought.

    2. COQuestion: Is your page in strict mode or quirks mode? What `doctype` are you using and is that doctype the very first thing at the top of your HTML? IE often does really weird things in quirks mode that are best forgotten about....

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
