loop

**higginbt** · 05-08-2006, 10:52 AM

I'm looking for help.

I have 5 fields on a form that i'm reading in as

var yr1cost = Form1.yr1Cost.value;
var yr2cost = Form1.yr2Cost.value;
var yr3cost = Form1.yr3Cost.value;
var yr4cost = Form1.yr4Cost.value;
var yr5cost = Form1.yr5Cost.value;

i know what to loop through these and check to see if there are null

for example

i = 0
do while 1<4
if

for example

i = 0
do while 1<4
if field null then display error
if field is 0 > greater then do something else
loop

my problem is i do not know how to loop throught the different fileds
i cant go from yr1cost to yr2cost
automatically

something like this:

HTML Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

	<head>
		<meta http-equiv="content-type" content="text/html;charset=iso-8859-1">
		<title>Untitled Page</title>
		<script type="text/javascript"><!--
function calc() {
	var yrcost = new Array;
	var missing = new Array;
	
	for (i=1;i<=5;i++) {
		if (eval("Form1.yr" + i + "Cost.value") == "") {
			missing.push(i);
		}
	}
	if (missing[0]) {
		alert("Please fill in the follwing Costs: " + missing);
		return false;
	} else {
		return true;
	}
}
//-->
</script>
	</head>

	<body bgcolor="#ffffff">
		<form id="Form1" action="" method="get" name="Form1" onsubmit="return calc();">
			<input type="text" name="yr1Cost" value="234" size="24">
			<p><input type="text" name="yr2Cost" value="" size="24"></p>
			<p><input type="text" name="yr3Cost" value="55" size="24"></p>
			<p><input type="text" name="yr4Cost" value="" size="24"></p>
			<p><input type="text" name="yr5Cost" value="7778" size="24"></p>
			<p><input type="submit" name="submitButtonName"></p>
		</form>
		<p></p>
	</body>

</html>

Eval is not the best way to cycle through, but I didn't want to change your field names. I usually add "req_" to te beginning of required fields, then check the entire form for fields starting with that and then check for null values.

Yeah, THanks i did it the same way by reading it into an array to start with

Quote:

var description = Form1.txtDesc.value
var CostArray=new Array()
CostArray[0]=Form1.yr1Cost.value
CostArray[1]=Form1.yr2Cost.value
CostArray[2]=Form1.yr3Cost.value
CostArray[3]=Form1.yr4Cost.value
CostArray[4]=Form1.yr5Cost.value

while (j<=4)
{
if (IsNumeric(CostArray[j])!=true)
{
numcount = numcount+1

}

j=j+1
}
