ajax, posting multiple checkbox values 1

[snowboardr]

I am trying to post multiple checkbox values... (they all have the same name different value) but its not working... IE says Object expected
I have checked my form names / ids etc... I have tried different methods to return the values... but its not working.

Regards

	function status(intstatus)
	{ 
	var str = "id=" + document.getElementById('mailchecks2') + "&status=" + intstatus; 
	var url = "/ajax/mail/mail_status.asp";
	xmlHttp=createRequestObject()
	xmlHttp.open("POST",url,true);
  	xmlHttp.setRequestHeader("Content-Type","application/x-[URL unfurl="true"]www-form-urlencoded;[/URL] charset=UTF-8");
	xmlHttp.send(str);
	LoadMAILHtml('0');
	}

how do you want them passed? as comma-delimited values? you'll need to loop through each checkbox and append the value to the querystring.

I didn't know you could submit multiple checkboxes with the same name. I usually do it with an array name in html

<input type="checkbox" id="mumu[0]" value="john">
<input type="checkbox" id="mumu[1]" value="ralph">
<input type="checkbox" id="mumu[2]" value="steve">

If they are checked and submitted as POST I'll have a POST array $_POST['mumu'] which is then accesses by
$_POST['mumu'][0]
$_POST['mumu'][1]
$_POST['mumu'][2]
etc . . .

How can i do this "loop through" in the javascript?

here's an example...

var cbCollection = document.forms['YourFormName'].elements['YourCheckboxName'];

for ( var i = 0; i < cbCollection.length; i++ ) {
    if ( cbCollection[i].checked ) alert( "Checkbox " + i + " is checked!" );
}

i wouldn't use getElementById - because IDs are supposed to be unique, therefore only of of your checkboxes should have the ID you're using.

Thanks for your help Cory... you will have to excuse me for my lack of javascript skills... but I am picking it up pretty well... I hated this language for the longest time... but then i found Ajax ... Hey i am having trouble removing the first letter of a string.... any why this doesn't work...

datacollecting = datacollecting + "&status=" + intstatus;
var datalength = Len(datacollecting);
datacollecting = Mid(datacollecting,2,datalength-1);

to get the length of a string, use this:

var datalength = datacollecting.length;

to gte the "mid" of a string, use this:

datacollecting = datacollecting.substring(2);
