Je ne suis pas devin !

Without knowing what dooes the function : no solution !
If something in the function stops it in error whith IE, probably
'false' is not returned ?

always to prefer the solution in form tag

<form onsubmit="return check_proc_sel()" blah >
....
<input type=submit class="btn" value="Terminate">
</form>

OT, but according to Dr Who it should be:

<form action='

'>
<input type=submit class="Dalek" value="Exterminate">
</form>

The function is as follows:

function check_proc_sel(){
var field = document.procs.process_checked;
var count = 0;
for (i=0;i&lt;field.length;i++){
if (field.checked==true){
count += 1;
}
}
if (count == 0){
alert("No process selected to Terminate or Kill")
return false;
}
else{
return true;
}
}

Try :

var field = document.procs.process_checked;
if(typeof field == 'undefined')
{
alert('no such field');
return false;
}
var count = 0;
for (i=0, n = field.length; i<n; i++)
{
if (field.checked) count++;
}
if (count == 0)
{
alert("No process selected to Terminate or Kill")
field.focus();
return false;
}
return true;
}


And use the onsubmit in tag form
instead of onclick in submit button

IE script debugger shows error in the following line

line ===> field.focus();
error ===> object doesn't support this property

doesn't understand that IE didn't display the message
"not such field" ? !

is(are) this(these) 'process_checked' is(are) checkbox(es) ?

try :

alert ("No process selected to Terminate or Kill");
if(field[0]) field[0].focus();
return false;

 

[Thomas 'PointedEars' Lahn]

var field = document.forms["procs"].elements["process_checked"];

if (!field)

(You are dealing with a host object here.)

window.alert(...);

for (var i = field.length; i--

(Order does not matter here, and this is faster.)

{
if (field.checked) count++;
}
if (count == 0)
{
alert("No process selected to Terminate or Kill")
field.focus();
[...]

Suppose count == 0, then no checkbox was selected. In that case you are
trying to focus *the checkbox group*, which is bound to fail. You need to
remove this statement or change it to field[0].focus() and the like. As
always, you should feature-test host object's method son runtime before you
call them.

Please trim your quotes as you can see here.

Is it neccessary to do it this way?

How about:
<form ..... onsubmit="check_proc_sel()">
...
</form>

<script type='text/javascript'>
function check_proc_sel()
{
I'm checkin but I don't like what I find so...
return false;
}
</script>
