VBScript: Checking if a form field exists

In javascript, there is a way to see if a form field exists....

PHP Code:


		
			
if(document.all.item("myField")) 

       alert("Field Exists");

Is there a way to do that same exact thing in VBScript.

Currently, I'm running a loop through all input objects searching for my item by name, which usually works okay, but my current page has thousands of checkboxes that I have to search through, and it's not completing quickly enough.

TIA.

Checkboxes only get detected if they have been checked. Meaning if you have the following code on your page.

Code:

for each name in Request.Form
    if(name = "Checkbox1") Then
        Response.write("Field Exists")
    end If
next

The checkbox name will only be detected IF That specific checkbox has been checked...otherwise it won't detect it.

Need it Client Side though.
Not in an action page from a form.
