Array help!!

[kenvin007]

Hi,
Please help. Here is the situation. I've tried to create a radio button
when clickeck by a user, a function will automatically check all
checkbox in a form. I've tried to do this using a for loop but I did
not have any luck.

My intention was when a user click on the radio button, checkbox for
testa,testb,testc,and testd will be checked.

<form name="myForm">
check all<input type="radio" name=alert value=all
onclick="checkAll(this)">
<font color="oliveDrab" size=1%>testa </font><input
type="checkbox" name=aix64testd value=aix64testd>
<font color="oliveDrab" size=1%>presto </font><input
type="checkbox" name=aix64testa value=aix64testa>
<font color="oliveDrab" size=1%>psyn </font><input
type="checkbox" name=aix64testb value=aix64testb>
<font color="oliveDrab" size=1%>psynim </font><input
type="checkbox" name=aix64testc value=aix64testc>

<script type="text/javascript">

function checkAll(Array1) {
var myArr = new
Array('aixtestd','aix64testa','aix64testb','aix64t estc');
for(var i; i<myArr.length;i++) {
document.myForm.myArr['+i+']=true;
}
}
<script>

Thx, -Christie

Why are you sending the object to the function? It is not needed the way it
is coded.
<script type="text/javascript">

function checkAll(Array1)
You never reference Array1. If this is the full code, you can remove it.
Don't forget that if you remove it from the call, you need to remove it from
the function and vice versa.

{ var myArr = new
Array('aixtestd','aix64testa','aix64testb','aix64t estc');
for(var i; i<myArr.length;i++) {
document.myForm.myArr['+i+']=true;

document.myForm.elements[myArr[i]].checked = true;

Try that.
Oh, and put attributes (like names and ids) in quotes. It can save a headache
later if you do odd things like use brackets, spaces, or start the attributes
with a number. i.e. checkbox name="aix64testa"

Note: this is not at all how I'd code this sort of thing, but hey. :)
