New Window w/ Form Submission 1

Hi,

I have a form that is being built dynamically with a recordset.

Code: 
<form name='frmReportGen' action='report.asp' method='post'>
<input type='checkbox' name='chkAddToReport' value='" & objRS("ID") & "'>
.
.
.
<input type="submit" value="Generate Report" onclick="validateForm(); return false;">
</form>

When the user submits the form, it generates a report built from which items the user checked in the form (e.g. it builds a recordset based on which IDs (checkboxes) were selected). I want the report to open in a new window. Here lies the problem.

I can get the report to open in a new window, but it ignores any checkboxes that were selected. The report generates correctly when I target the same window. You can see I'm also checking to make sure at least one checkbox was selected too.



Thanks for any help!

Code: 
function validateForm() {
	var checkFound = false;
	for (var counter=0; counter < document.forms['frmReportGen'].length; counter++) {
		if (document.forms['frmReportGen'].elements[counter].checked == true) {
			checkFound = true;
		}
	}
	if (checkFound != true) {
		alert("You must check at least one item before running a report!");
		return false;
	} else {
		document.forms['frmReportGen'].target = 'myRptWin';
		var winLeft = (screen.width - 800) / 2;
		var winTop = (screen.height - 675) / 2;
		windowName = "myRptWin";
		var windowFeatures = "width=800,height=675,status,scrollbars,resizable,left=" + winLeft + ",top=" + winTop 
		newWindow = window.open('report.asp', windowName, windowFeatures);
		newWindow.focus();
	}
}

What is this:

Code: 
    for (var counter=0; counter < document.forms['frmReportGen'].length; counter++) {
        if (document.forms['frmReportGen'].elements[counter].checked == true) {
            checkFound = true;
        }
    }

Supposed to be doing?

Forms[''].length should give you a value of 1.

That (supposedly?) loops through all the checkboxes in the form and indicates whether or not there are no checkboxes checked. There can be possibly many checkboxes in the form.

If you don't mind a slight re-write...

Code: 
var checkFound = false;

// get all form elements
var els = document.forms['frmReportGen'].elements;

// loop through each element
for (var i = 0; i < els.length; i++) {
    // if this element is a checked checkbox
    if (els[i].type == 'checkbox' && els[i].checked)
        checkFound = true;
}

Take this simple example:

Code: 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
	"[URL unfurl="true"]http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">[/URL]

<html>
<head>
<title>Untitled</title>

<script>
function doSomething(f) {
    var w = window.open('','myWin','height=400,width=400');
    f.target = 'myWin';
}
</script>

</head>

<body>

<form name="f" onsubmit="doSomething(this);">
<input type="submit" />
</form>


</body>
</html>

It works fine. Try opening the window first. And there's really no need to open it to "report.asp" since I assume you're calling this from the onsubmit event of the form.

Am I correct?

Thanks much for the help...

Yes, I am still getting the same error...

Here's the source of the page that generates the form:

Code: 
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<link href="includes/style.css" type="text/css" rel="stylesheet">
<script>
function validateForm() {
    var checkFound = false;

    // get all form elements
    var els = document.forms['frmReportGen'].elements;

    // loop through each element
    for (var i = 0; i < els.length; i++) {
    // if this element is a checked checkbox
        if (els[i].type == 'checkbox' && els[i].checked)
            checkFound = true;
    }
    if (checkFound != true) {
        alert("You must check at least one item before running a report!");
        return false;
    } else {
        document.forms['frmReportGen'].target = 'myRptWin';
        var winLeft = (screen.width - 800) / 2;
        var winTop = (screen.height - 675) / 2;
        windowName = "myRptWin";
        var windowFeatures = "width=800,height=675,status,scrollbars,resizable,left=" + winLeft + ",top=" + winTop
        newWindow = window.open('report.asp', windowName, windowFeatures);
        newWindow.focus();
    }
}
</script>
</head>

Three slight changes got it working for me:

#1
Code: 
newWindow = window.open([red]''[/red], windowName, windowFeatures);

#2
Code: 
<form name='frmReportGen' ... [red]onsubmit="return validateForm();"[/red]>

#3
Code: 
<input type="submit" value="Generate Report">

Try those changes.
