Arrays

I've got a problem with arrays. I have a button that resets my form, but it doesn't do what I need for dropdown lists. Under "Actions" I added a piece Javascript to set the dropdown list to the "initial" state I need.

Now this code works:

this.getField("Student1").value="SSS"
this.getField("Student2").value="SSS"
this.getField("Student3").value="SSS"

But this doesn't work

v= new Array("Student1","Student2","Student3");
for (i=0; i<v.length; i++)
this.getField(v[i]).value="SSS"

What really confuses me is that it works for two of the three entries in the array.

Stumped and could use help.

Resetting a field means returning it to its default value.

You should try this:

for (i=0; i<4; i++) {this.getField("Student" + i).value = this.getField("Student" + i).defaulValue;}

No, we are on the wrong track here.

The problem isn't resetting a dropdown list, which works fine, the problem is that the code is trying to reset three dropdown lists and the loop ends prematurely. I put some alerts in there and the loop execution really ends prematurely.

What happens when you use:

this.resetForm (v);

I'm afraid it did even less. It acted exactly the same way as using the default "reset form".

The problem here is that there appears to be no clear definition of "resetting a dropdown list". One would assume it means setting it back and the initial default values, but apparently it is not.

Check the Javascript console for errors.

I admit that I'm not positive how to check the javascript console, but I have Acrobat set to pop up a window when there is a problem (i.e. undefined field), and nothing comes up. (See below)

See if this will work:

for(var i=1; i<=3; i++)
this.getField("Student"+i).value = "SSS";
