Javascript to make all fields visible

[YUET281698597y6a]

I am completely new with javscrtipt.

I got over 100 fileds in form and wanna show them all with one click. Is there any way of doing with simple scripting other than calling the field one by one ?

var r1 = this.getField("aa");
var r2 = this.getField("bb");
var r3 = this.getField("cc");
var r4 = this.getField("dd");

var flagBtn = this.getField("Flag");
var showAll = flagBtn.buttonGetCaption();
if(showAll == '0')
{
flagBtn.buttonSetCaption('1');
r1.display = display.visible;
r2.display = display.visible;
r3.display = display.visible;
r4.display = display.visible;
}
else
{
flagBtn.buttonSetCaption('0');
r1.display = display.hidden;
r2.display = display.hidden;
r3.display = display.hidden;
r4.display = display.hidden;
}

You can put the names in an array and then use a loop to access all of them, like this:

var fields = ["aa", "bb", "cc", "dd"];
var flagBtn = this.getField("Flag");
var showAll = flagBtn.buttonGetCaption();
if (showAll == '0') {
	flagBtn.buttonSetCaption('1');
	for (var i=0; i<fields.length; i++) {
		var f = this.getField(fields[i]);
		f.display = display.visible;
	}
} else {
	flagBtn.buttonSetCaption('0');
	for (var i=0; i<fields.length; i++) {
		var f = this.getField(fields[i]);
		f.display = display.hidden;
	}
	
}

What do you mean by "grouping"?

[Thom Parker]

If by grouping you mean using the "dot" field naming notation, then yes. It's the best way to provide easy access to a group of fields for scripting purposes.
