Loops and Arrays in Validation

[TheForge]

First off, Im new to programming so go easy on me .

I have created an array of strings with all of my html input box names in order to ensure no empty fields. I want to check these via a while loop (any loop wll do). But when I try to input my array name and index number it tells me that "Object does not support this method or property".

Here is a piece of the code.
veriForm = form name
allFields = array name

counter = 0
While counter < allFields.Ubound()
      if (veriForm.allFields(counter).value =&quot;&quot;)Then
        MsgBox &quot;All fields are required!&quot;
        flag = false
        counter = allFields.Ubound()
      else
        counter = counter + 1
      end if
Wend

I would be grateful for any amount of help....Thanks.

Try it this way:
alertStr = ""

FOR i = 0 to document.myForm.elements.length - 1
select case uCase(document.myForm.elements(i).type)
case "TEXT", "SELECT",
IF document.myForm.elements(i).value = "" THEN
alertStr = alertStr & vbcrlf & "- " & document.myForm.elements(i).name
end if
end select
NEXT

if alertStr <> &quot;&quot; then
alert &quot;You need to fill the following:&quot; & alertStr
exit sub
end if


Here's another method which highlights required fields....

function checkForm()
checkForm = true
for i = 0 to document.CBR.elements.length -1
select case i
case 0,1
if document.cbr.elements(0).checked = false and document.cbr.elements(1).checked = false then
document.all.cbr.elements(0).style.background = &quot;yellow&quot;
document.all.cbr.elements(1).style.background = &quot;yellow&quot;
checkForm = false
else
document.all.cbr.elements(0).style.background = vbdefault
document.all.cbr.elements(1).style.background = vbdefault
end if
case 2,3,8,9,10,13
if document.cbr.elements(i).value = &quot;&quot; then
checkForm = false
document.all.cbr.elements(i).style.background = &quot;yellow&quot;
end if
case 6,7
if document.cbr.elements(6).checked = false and document.cbr.elements(7).checked = false then
document.all.cbr.elements(6).style.background = &quot;yellow&quot;
document.all.cbr.elements(7).style.background = &quot;yellow&quot;
checkForm = false
else
document.all.cbr.elements(6).style.background = vbdefault
document.all.cbr.elements(7).style.background = vbdefault
end if
case 4,5,12 'one of these must be filled out'
if document.cbr.elements(4).value = &quot;&quot; and document.cbr.elements(5).value = &quot;&quot; and document.cbr.elements(12).value = &quot;&quot; then
checkForm = false
if document.cbr.elements(i).disabled = false then
document.all.cbr.elements(i).style.background = &quot;yellow&quot;
end if
end if
end select
next
if checkForm = false then
alert &quot;Please fill in these required spaces!&quot;
end if
end function

FOR i = 0 to document.myForm.elements.length - 1
select case uCase(document.myForm.elements(i).type)
case &quot;TEXT&quot;, &quot;SELECT&quot;, <-- oops!, extra comma - also note that this works in IE only.....
IF document.myForm.elements(i).value = &quot;&quot; THEN
alertStr = alertStr & vbcrlf & &quot;- &quot; & document.myForm.elements(i).name
end if
end select
NEXT

Thanks alot, couple of areas I'm a bit unsure about.

document.myform.element

document- Is this a variable? Or is it a function of VBS?

element- this is where I would input my array name right?

Sorry if these questions seem overly simple....but I am completly new to this.

Thanks again for your help.

document is object for the entire page. I didn't work w/ your code at all - I tried to give you a completely new solution.

You don't need to create any array - it already exists:

document.myForm.elements = array of elements on the form &quot;myForm&quot;
-- remember that this includes buttons and hidden elements
WITH document.myForm.elements(i)
.name = the element's name
.value = the element's value
.type = the element's input type
END WITH

Thie first code I wrote looks at form elements based on their input type. It then compiles a list of all blank text boxes or selects. If any are found, it displays a list of incomplete elements (by their name).

The second code looks at form elements based on their position in the form. Any required fields that are incomplete are highlighted. -- Just trying to help...

Cool, no need to make an array.
That is a neat little tool.
