    <p>Okay, this is following on from my previous question reguarding performing a simple ajax request that, once the request has returned a readyState of 4 and a status of 200 it inserts the response into a div and slides it down nicely. I don't want it to be performed using a toolkit such as jQuery or scriptalicious.</p> <p>here is the original question:<br /> <a href="https://stackoverflow.com/questions/1531951/ajax-with-slide-effects-onready-witout-using-a-toolkit"><a href="https://stackoverflow.com/questions/1531951/ajax-with-slide-effects-onready-witout-using-a-toolkit">Ajax with slide effects onready witout using a toolkit</a></a></p> <p>So far I have managed to get it all working quite nicely. However I have the problem that, the text returned is shown and then the div expands. I need it to work with the div and text expanding together.</p> <p>Here is my code</p> <pre> function slideDown() { document.getElementById('slideDiv').style.visibility = 'hidden'; xmlhttp.open("GET", "parse.php?what=main", true); xmlhttp.onreadystatechange = function() { if (xmlhttp.readyState == 4 && xmlhttp.status == 200) { document.getElementById('butt').value = 'hide'; document.getElementById('slideDiv').innerHTML = xmlhttp.responseText; document.getElementById('slideDiv').style.display = 'block'; var fHeight = document.getElementById('slideDiv').offsetHeight; document.getElementById('slideDiv').style.height = '0'; document.getElementById('slideDiv').style.visibility = 'hidden'; function timeIt() { function bar() { timeSlide(fHeight); } setTimeout(bar, 10); } timeIt(); } } xmlhttp.send(null); } function timeSlide(fHeight) { var fHeight; var diff; document.getElementById('slideDiv').style.visibility = 'visible'; var cHeight = document.getElementById('slideDiv').clientHeight; if (cHeight &lt; fHeight) { cHeight = cHeight + 3; document.getElementById('slideDiv').style.height = cHeight+'px'; function timeIt() { function bar() { timeSlide(fHeight); } setTimeout(bar, 10); } timeIt(); } else { endSlide(); } } </pre> <p>I <em>think</em> this is happening due to using the following to put the returned get request into the div.</p> <pre> document.getElementById('slideDiv').innerHTML = xmlhttp.responseText; </pre> <p>Can someone please put me in the correct direction with this? I'm not particularty good with JavaScript and I'm probably going the complete wrong way about it so any pointers would be great! Thanks in advance!</p>

    1. COIn slideDown(), where you call document.getElementById('slideDiv') many times, I think you can improve readability (and probably performance) by setting `var slideDiv = document.getElementById('slideDiv');` at the top, then using that instead.

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.
