VbScript form Validation with an array 1

[WorkSuxs]

This has been bugging me for some time now. I get a (dynamic) list of a product name and description from a database that is loaded into arrays. I then display the product name and allow the users to edit the descriptions. I loop thought the arrays and use the following for the description: <input name="productDescription(<%=h%>)" size=50 maxlength=75 value="<%=productDescription(h)%>">

The issue is I want to validate that there is a description when they click the submit button. I have tried this and it does not work.

Function UpdateProductDescription_onSubmit()
Dim h, errorFound
For h = 1 to document.UpdateProductDescription.nbrofrecords.value
If Len(Trim(document.UpdateProductDescription.productDescription(h).value)) = 0 Then
str = alert("Product Description is Required")
errorFound = “True”
Exit For
End If
Next
If errorFound = “True” Then
UpdateProductDescription_onSubmit = False
Else
document.UpdateProductDescription.action = "test.asp"
UpdateProductDescription_onSubmit = True
End If
End Function

Unless you somehow KNOW that a page will only ever be used with Internet Explorer then clien-side script should be done in JavaScript.

Thanks tsuji, that worked!

Sheco, I'm in a large company and the standard is for MS IE only. I should have posted that with the original question.

let's hope no one decides to change that policy in the future...

Or that you ever need to open up these web applications to a partner - e.g. a customer or vendor or outsource partner who has a different view of the world when it comes to standards compliant tools.

Or use it on a device that doesn't support IE.

Or want to demonstrate to future employers how well you understand web design and development standards and cross platform solution development.
