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);

OK - Some progress, finally. Here is how I am using this. From the "Actions" for the button.

and it fails. but when I change this to run the Javascript before the reset form,

it works. Of course this causes other problems, but I can handle those. It still bothers me that the loop didn't work. There is something going on here that I don't understand.

Sorry - Same results.

Are there any error messages in the JS Console? Can you share your actual file with us?

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";
