Prompter class inside function

[Bob Williams]

This is likely just my JavaScript ignorance shining through, but I’m trying to use the Prompter class for the first time. My code works fine if I plop it into the global scope, but if I try to wrap it in a function, the variables never get filled in. I’ve also tried wrapping it inside a class method (passing this.xxx as the variables to fill in), but that doesn’t work, either.

Here’s my code:

// function getCopyInformation() {
	var noteRowNumber;
	var toRecordId;
	var preserveSorter;
	
	var prompterResultHandler = function (result) {
		if (result === true) {
			console.log('noteRowNumber: ' + noteRowNumber);
			console.log('toRecordId: ' + toRecordId);
			console.log('preserveSorter: ' + preserveSorter);
		} else {
			console.log('Canceled');
		}
	};

	let prompter = Prompter.new();
	prompter.cancelButtonTitle = 'Cancel';
	prompter.continueButtonTitle = 'Copy';
	prompter.addParameter('Note row number: ', 'noteRowNumber')
		.addParameter('Target record ID: ', 'toRecordId')
		.addParameter('Preserve sorter value? ', 'preserveSorter', 'popup', ['Yes', 'No'])
		.show('Where do you want to copy the note?', prompterResultHandler);
// }

// var destination = getCopyInformation();

So run like this, it works. But if I uncomment the three commented lines, the three variables show as undefined (though result does still get set properly, so the log calls are still run).

Any suggestions?

Yeah, the variables the prompter access’ need to be in the global scope:

var noteRowNumber;
var toRecordId;
var preserveSorter;

var prompterResultHandler = function (result) {
	if (result === true) {
		console.log('noteRowNumber: ' + noteRowNumber);
		console.log('toRecordId: ' + toRecordId);
		console.log('preserveSorter: ' + preserveSorter);
	} else {
		console.log('Canceled');
	}
};

function getCopyInformation() {

	let prompter = Prompter.new();
	prompter.cancelButtonTitle = 'Cancel';
	prompter.continueButtonTitle = 'Copy';
	prompter.addParameter('Note row number: ', 'noteRowNumber')
		.addParameter('Target record ID: ', 'toRecordId')
		.addParameter('Preserve sorter value? ', 'preserveSorter', 'popup', ['Yes', 'No'])
		.show('Where do you want to copy the note?', prompterResultHandler);
}

var destination = getCopyInformation();

Hmm, ugly, but good to know. Thanks!

I use one global variable/object for this purpose that I share among different Prompters.
