Hi All,
I'm seeing a strange issue with my code below. The content received thru the xmlHttpRequest, is not being displayed in IE8, after clicking the link. It is displayed only after moving the mouse/cursor, after clicking the link. Anyone sees what could be the problem here ? Please help. -
<html>
-
<head>
-
<script type="text/javascript">
-
-
var xmlHttpfunction;
-
function ShowHint(id)
-
{
-
xmlHttp = GetXmlHttpObject();
-
-
if (xmlHttp == null)
-
{
-
alert ("Browser does not support HTTP Request");
-
return;
-
}
-
-
var url = "myurl.php";
-
url = url+"?id="+id;
-
xmlHttp.onreadystatechange = stateChanged;
-
xmlHttp.open("GET",url,true);
-
xmlHttp.send(null);
-
}
-
-
function stateChanged()
-
{
-
if (xmlHttp.readyState === 4)
-
{
-
document.getElementById("elementRight").style.display = "block";
-
document.getElementById("elementRight").innerHTML = xmlHttp.responseText;
-
}
-
}
-
-
</script>
-
</head>
-
<body>
-
<div id="elementLeft">
-
<ul >
-
<li>
-
<a href="#" onclick="ShowHint("1");"> Item1 </a>
-
</li>
-
<li>
-
<a href="#" onclick="ShowHint("2");"> Item1 </a>
-
</li>
-
<li>
-
<a href="#" onclick="ShowHint("3");"> Item1 </a>
-
</li>
-
</ul>
-
</div>
-
<div class="element" id="elementRight">
-
</div>
-
</body>
-
</html>
-
The css for 'element' is - -
.element {
-
overflow:hidden;
-
border:1px;
-
border:#7CAFBE solid 1px;
-
height:50%;
-
width:79%;
-
float:right;
-
padding:0 0 0 10px;
-
padding-left:1px;
-
z-index:1000;
-
}
-
Many Thanks,

csoft,
I am surprised that you're seeing anything at all, considering the apparent syntax errors in lines 38, 41, and 44, where you have apparently violated HTMLs quoting rules. For example: - <a href="#" onclick="ShowHint("1");"> Item1 </a>,
Should probably be: - <a href="#" onclick="ShowHint('1');"> Item1 </a>,
Nevertheless, since it is working, that is not the fundamental problem that you're encountering...
The second problem I see is that you aren't stopping the anchor link in your code snippet. You probably should add a return false; to each of the events, like this: - <a href="#" onclick="ShowHint('1'); return false;"> Item1 </a>,
Luck!
Oralloy
Oralloy,
Thanks for responding.
This was a typo, while copying the code - -
<a href="#" onclick="ShowHint("1");"> Item1 </a>
-
Sorry about that.
I now have the following, as you suggested - -
<a href="#" onclick="ShowHint('1');return false;">
-
Item1
-
</a>
-
But, I still see the same result.
Actually, when I click on the link 'Item1', a dotted border around 'Item1' appears and only when I move the mouse arrow out of this dotted border, the content is loaded. Has this got anything to do with the anchor tag itself ? The following is the css for the anchor tag - -
a {
-
color:#000000;
-
text-decoration: none;
-
font-family: verdana;
-
font-size: 11px;
-
padding:0 0 0 10px;
-
text-align: center;
-
cursor: pointer;
-
}
-
Thanks Again,
csoft

You may be running into variable scoping rules with xmlHttp.
Try hoisting the onreadystatecha nge to an anonymous function, like this: - function ShowHint(id)
-
{
-
xmlHttp = GetXmlHttpObject();
-
-
if (xmlHttp == null)
-
{
-
alert ("Browser does not support HTTP Request");
-
return;
-
}
-
-
var url = "myurl.php";
-
url = url+"?id="+id;
-
xmlHttp.onreadystatechange =
-
function(){
-
if (xmlHttp.readyState == 4)
-
{
-
document.getElementById("elementRight").style.display = "block";
-
document.getElementById("elementRight").innerHTML = xmlHttp.responseText;
-
}
-
}
-
xmlHttp.open("GET",url,true);
-
xmlHttp.send(null);
-
}
Also, I changed the state comparison from absolute equality (===) to simple equality (==).
Luck!

Hi Experts.
Please put the code sample below into an html document and take a look
at in NN6+. One span should be shown while the other is hidden.
Clicking the button should reverse this. However it doesn't.
Removing the table structure from around the text fixes it, but I need
the table structure (this is very simplified example).
Hope someone can provide an alternative?

I need to change the style of an element changing its padding-left property (got it in firefox but IE is a different battle..). I can use document.getElementById().style.XX
to everything i need, except with padding-left, as it is separated by a ' - ' and it is not correct to use it as it was supposed to:
document.getElementById('el').style.padding-left = '5px'
will throw 'invalid assignment left-hand side', as expected..
Any help...

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
