[Added] nuPrompt() JavaScript function

[admin]

The nuPrompt() function displays a dialog box that prompts the user for input.

Show the prompt window:

Code: Select all

nuPrompt('How are you?','Random Question');

Declare a callback function to retrieve the input value:

Code: Select all

function nuOnPromptClose(val, ok) {
 if (ok) {
     nuMessage(['You entered:',val]);
 }
}

Passing callback as function reference
(available as of V.4.8-2025.06.14.05)

In addition to passing the callback as a string (the name of a function), you can also pass a function reference directly. This allows you to pass additional parameters to your callback using closures.

Example:

Code: Select all

// Some context data that you want to pass to the callback
let customerID = '12345';
let currentDate = '2025-06-14';

nuPrompt('Enter comment:', 'Add Note', '', '', function (val, ok) {
    if (ok) {
        saveNote(customerID, currentDate, val);
    }
});

function saveNote(customerID, date, noteText) {
    nuMessage(['Saving note for customer:', customerID, 'Date:', date, 'Note:', noteText]);
}

Why this is useful:

• Allows you to pass additional data into the callback (e.g. IDs, dates, context-specific values).
• Supports modern JavaScript best practices: anonymous functions, arrow functions, closures.
• Fully backward compatible — string function names are still supported.
