View Full Version : IIF and textboxes

12-13-2011, 08:33 PM

I need your help,

I can seem to get this to work.

I want to be able to use an IIF to check if a textbox empty ie.

IIF(textbox1 = "" || textbox = null, "it is empty","it is not empty")

This doesnt seem to be working.

Any ideas?

There is no such thing as IIF in JavaScript.

In fact, IIF doesn't even exist in VBScript.

IIF exists in Visual Basic and in VBA (Visual Basic for Applications) and in VB.NET. So far as I know, those are the only places you find it.

In JavaScript, perhaps you are looking for something like this:

var answer = (form.textbox1.value == "" || form.textbox1.vakue == null ) ? "it is empty" : "it is not empty";

Maybe it is time to start here?? http://www.w3schools.com/js/

By the by, if indeed you are talking about <input name="textbox1" />, then the .value of such a field is *NEVER* empty. Form fields that have a .value property *always* return a STRING for that .value. Yes, it can be an empty string ("") but it can't be null.

So it would be sufficient to code

var answer = ( myform.textbox1.value == "" ) ? "it is empty" : "it is not empty";
