Re: Javascript Checkbox Problem...
There is 2 type Checkbox...
ChkGrp and ChkPil (Array of Checkbox) ....
If I check "ChkGrp", I want ChkPil[0] was checked too... (only index 0 )...
So I call function Cek01 on ChkGrp...
But It doesn't work...EXCEPT if change name of "ChkPil[]" to "ChkPil"...
But IF I CHANGE NAME to ChkPil.... when I send to other Page... with :
$_POST["ChkPil"]; It's only return 1 value
But with "ChkPil[]" when I send to other page , i can make array of this variable :
$test=$_POST["ChkPil"];
$text="";
for($i=0;$i<sizeof($test);$i++)
{
$text = $text . $test[$i];
}
Just like that...

Re: Javascript Checkbox Problem...
have you tried, using getElementByName or getElementById to access the element to change the value of it?

Re: Javascript Checkbox Problem...
Doesn't works...  (
if i'm using
Code:
alert("document.forms['FrmCheck'].ChkPil+'[0]'.checked);
it will show alert "NaN";
If i'm using Javascript Console on Firefox , it will show :
"Invalid assignment left-hand side"...

Re: Javascript Checkbox Problem...
that will be either outputing True or False
and i don't think js will try to convert that to 0 or 1
so i think that's why you get NaN(Not a Number)

Re: Javascript Checkbox Problem...
I think it should be
Code:
alert(document.getElementByName('ChkPil[0]').checked);
There should be no data type conversion happening. See what that returns.

Re: Javascript Checkbox Problem...
Also, if you want to get a form element:
Code:
document.forms[0].elements['ChkGrp[]'];
If it is a list of checkboxes you'll get an array of elements.
