What is Javascript for clear field?

[ScreenNameName]

I am trying to figure out how to clear fields via javascript if a checkbox is triggered. Anyone have a script? What exactly is the JS term to clear fields? 

[try67]

this.resetForm(["Field1", "Field2", "Field3"]);

It depends whether you mean "set to blank" or "set to default value (which might not be blank)".

Case 1: set to empty string (or what is appropriate for non-text fields)

Case 2: resetForm indeed.

Thank you Test Screen Name, 

So would the script look like this for case 1? 

CASE 1:-

this.emptyString(["Field1", "Field2", "Field3"]);

No, that's not how you would clear the fields to an empty string instead of the default (case 1). There is no single call for that, you need to reset each one separately or in a loop.

"So would the script look like this for case 1? "

for (var i = 1; i < 4; i++) {
this.getField("Field" + i).value = "";
}

That's in case those are the actual field names. A more generic example is this:

var fields = ["Field1", "Field2", "Field3"]; // replace with actual field names
for (var i in fields) {
	this.getField(fields[i]).value = "";
}
