Okay, first this seems to be a javascript issue not a php issue so I've reported it so that it can be moved to the correct forum - you;ll get better help that way,
Second, you need to answer the following questions:
1. What is the code doing that it should not do?
2. What is the code not doing that it should do?
3. Are you getting any error message? - If so please give them.
I assume this JS function is called from some sort of onchange event handler on the text box.
Cheers

Please friend post the Html code on which you are operating the code.
As I can observe from your code is that you have sets of text fields.And there is button
if the user has not enter any of the field then on pressing that button it should give alert
to fill at least one .
So this could be the solution to your code: - function validation()
-
{
-
var chks = document.getElementsByName('rr[]');//here rr[] is the name of the textbox
-
var flag=0;
-
for (var i = 0; i < chks.length; i++)
-
{
-
if (chks[i].value!="")
-
{
-
flag=1;
-
}
-
-
-
-
}
-
-
if (flag==0)
-
{
-
alert("Please fillup atleast one textbox");
-
return false;
-
}
-
else return true;
-
-
}
Can u please tell me what is the content of the textbox "rr[ ]" wether rr[ ] is the name of a single textbox or are u having many text box with the name "rr".
If you are having a single text box means, here is your answer. Use Id instead of name.
[HTML]//HTML code
<input type="text" id="myText" onblur="validat e()">[/HTML]
//JS code
[HTML]function validate()
{
if(document.get ElementById('my Text').value==" ")
{
alert("Please Enter the Value");
document.getEle mentById('myTex t').focus();
}
}[/HTML]

It's not enough just to say it's not working. That could mean absolutely anything.
Having said that, I think the solution provided by Rsmastermind should work for you.

mageswar005, as a full member now, you should know that we expect your code to be posted in [code] tags (See How to Ask a Question).
This makes it easier for our Experts to read and understand it. Failing to do so creates extra work for the moderators, thus wasting resources, otherwise available to answer the members' questions.
Please use the tags in future.
In addition to this, please do not double post your questions.

You don't need to Focus on an element to check if it has content.
You can retrieve all of the Input elements on your page, loop through all of the elements check if the type is a text box...if the text box's name contains "rr"...and if that text box contains anything as it's value.
For example -
function validation()
-
{ var allElements=document.getElementsByTagName('input');
-
var len=allElements.length;
-
for(var i =0; i < len; i++
-
{
-
var checkElement = allElements[i];
-
if(checkElement.type=="text")
-
{
-
/* You know that the checkElement variable contains
-
a text box element....
-
here check if the text box's name contains rr
-
and check if the text box contains any value
-
Keep a count of the number of text boxes contains a value
-
and only display the alert if this number is 0 after you finish
-
looping through all of the elements.
-
*/
-
}
-
}

}

Hello,
This is the only line in my entire code that does not validate in
XHTML :

However, it is valid HTML,since I've defined the function color in the
javascript section of the <head> tag.
