enumerate checkbox counting issue

[leahyj]

Hello:

For some reason, my code is returning my checkboxes(values) twice. Same result using for loop and do while loop.

function paynow()
{

var elems = document.lienslist_frm.elements;
var i = 0

do
//for(i=0; i<elems.length; i++)
//trying do while loop this time instead of for loop
{

if(elems[i].type=="checkbox" && elems[i].name=="chkPayNow" && elems[i].checked){ 

	alert(document.lienslist_frm.elements[i].value);
	alert(elems[i].type); 
	alert(elems[i].name); 

	}
i++
}
while(i<elems.length)
return true;
}

This is my form:

<form name="lienslist_frm">
<td><font size="2">A11348000463</font></td>
<td><font size="2">&nbsp;</font></td>
<td><font size="2">2004</font></td>
<td align="right"><font size="2">$27.59&nbsp;&nbsp;</font></td>
<td align="center"><font size="2">No</font></td>
<td><font size="2"><input type="checkbox" name="chkPayNow" value="A11348000463"></font></td>
</tr>
</table>
</form>

Thanks in advance.

this works fine...

<script type="text/javascript"><!--
function paynow() {
    var elems = document.lienslist_frm.elements;
    for(i=0; i<elems.length; i++) {
        if(elems[i].type=="checkbox" && elems[i].name=="chkPayNow" && elems[i].checked){
            alert(document.lienslist_frm.elements[i].value);
            alert(elems[i].type);
            alert(elems[i].name);
        }
    }
    return true;
}//--></script>

it helps to indent your code, so you can see what different blocks are doing.

it also helps to post your ACTUAL code. if that was really your code, then your function was never being called.

To cLFlaVa:

Thanks.

I am calling my function from a button in another form.

Anyway,

for some reason, I get the values twice.


Thanks.

 

[cLFlaVA]

still? then you have two checkboxes in your HTML.

guess what:

I had my function being called from the <form onsubmit="javascript:return paynow();"> tag and the <input onclick="paynow();"> tag.

That's why it was happening twice.

As long as I got your attention, is there any preference or difference?

 

[cLFlaVA]

my preference is the onsubmit event, because you can return false properly to cancel the submission if need be.
