How can I find & show/hide form fields with a specific strings start with "List1_", "List2_" in the field name and make them hidden until triggered.

I need the regular expression format to find the form fields name start with "List1".

Example

this.getField("List1_Oldfactory").display = display.hidden;
this.getField("List1_Optical").display = display.hidden;
this.getField("List1_Glosso").display = display.hidden;
this.getField("List1_Trigeminal").display = display.hidden;

Need to convert something like,

this.getField("List1_"+(/\s/g)).display = display.hidden;

but got error in condole as,

TypeError: this.getField(...) is null 1:Field:Mouse Up

You can do it like this:

for (var i=0; i<this.numFields; i++) {
	var f = this.getField(this.getNthFieldName(i));
	if (f==null) continue;
	if (/^List1/.test(f.name)) f.display = display.hidden;
}
