hi there,

(i am using jquery-1.3.2.min.js and mvc)

I have several labels and textboxes in my page.  
50% of them have the word "Sdc" in the id  - i.e "SdcStartLabel" "SdcEndLabel" "SdcTextbox" etc etc

After the page has loaded, if a certain value is false - i want to disable all the labels and textboxes  that have "Sdc" in their id.

When i say disable - for the labels - i want to make the back ground grey - and put "N\A" and for the text inputs - to actually disable them.

Is this possible to do in one statement - rather than explicitly call every label and text box.

If so could someone show me how.

thanks

Hi

var trlist = $('tbl_registration').getElementsByTagName('label');
            var arrTr = $A(trlist).findAll(function (node){return node.id.match("^Sdc")});
            arrTr.each(function(node){
                  node.style.display = action ;
            });

Hi,

where action = block or none .
which would do show and hide

u can even pass these parameter thru ur function so that only one function can be used to both label and ur textbox or checkbox and anything else

Try this (replace variable cond with your condition):
<head>
<style>
.disable { 
background-color:#bca; 
border:1px solid green;
}
</style>
<script src="http://code.jquery.com/jquery-latest.min.js"></script>

<script>
var cond = false; //your conditon

$(document).ready(function () {
 if (!cond)
 {
	$('*[id^=Sdc]').each(function (){
		if ($(this).attr("tagname")=="LABEL")
			$(this).attr("className", "disable");
		if ($(this).attr("tagname")=="INPUT")
			$(this).attr("disabled", true);
	});
 }
});

</script>
</head>
