Hello
In aspx, I need to hide a <div> with javascript, based on certain condition.

I tried to code:

<SCRIPT language="javascript">
 function ShowHide(xx) {

            if (xx == 'condition') {
                return "display:none;";
            }
            else {
                return "";
            };
        }	
</SCRIPT>

<div  style='javascript:ShowHide("condition");'> 
               Hello
</div>     

Open in new window

But no success. Word Hello is still showing.

Javascript events must be in something like 'onclick', not in a style attribute.  More info here: http://www.w3schools.com/jsref/dom_obj_event.asp

Try this one:
<!DOCTYPE HTML>
<html>
<head>
<meta charset="utf-8">
<title>Untitled Document</title>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script>
<script>
$(document).ready(function(e) {
    var myval=$('#mydiv').attr('style');
	if(myval=='condition'){
		$('#mydiv').show();
	}else{
		$('#mydiv').hide();
	}
});
</script>
</head>
<body>
<div id="mydiv" style="condition">Hello</div>     
</body>
</html>

No success.
Is there a way to hide or show a div programmatically not with server code but with client code?

If all you are trying to do is show/hide, there is no need for a "condition" parameter.  You can extract the css display property from the target element (the element you are trying to show/hide) and based on its value, you either show it or hide it.  The code below is client side code.
<script type="text/javascript">
function ShowHide(targetElement, triggerElement) {
	targetElement.style.display = targetElement.style.display=='none'?'':'none';
	triggerElement.value = targetElement.style.display=='none'?'Show':'Hide';
}	
</script>
<input type="button" value="Hide" onclick="ShowHide( document.getElementById('theDiv'), this )" />
<div id="theDiv"> 
               Hello
</div>

Try this:

<SCRIPT language="javascript">
 function ShowHide(id) {

 	var box = document.getElementById(id);
 	var xxx = box.style.display;

    if (xxx == 'none') {
       box.style.display = "block"
    }
    else {
       box.style.display = "none";
    };
}	
</SCRIPT>

<div id="example">Hello</div>     

<a href="javascript:ShowHide('example');">Show/Hide</a>

If you just want to always hide it, just put this at the bottom of the page:
<script type="javascript/text">
document.getElementById('your_id_goes_here').style.display = 'none';
</script>

Open in new window


Ideally, this would go into a document-ready or window-load function as described above.

Or... use the ShowHide function previously posted Zeikcan and place a call to that function as described in the code sample above.

Here is the working code:
<SCRIPT language="javascript">
 function ShowHide(obj, xx){
            if (xx == 'condition') {
                obj.style.display = 'none';
            }
        }	
</SCRIPT>

<div onClick='ShowHide(this, "condition");'>
    Hello
</div>
