Terima kasih kepada 0A0D untuk jawaban yang bagus. Saya beruntung dengan itu. Darin Dimitrov juga membuat argumen yang bagus tentang membatasi kerumitan file JS Anda. Namun, saya menemukan kesempatan di mana fungsi runtuh ke definisi mereka membuat browsing melalui file jauh lebih mudah.
Mengenai # wilayah secara umum, Pertanyaan SO ini mencakup dengan cukup baik.
Saya telah membuat beberapa modifikasi pada Makro untuk mendukung runtuhnya kode lebih lanjut. Metode ini memungkinkan Anda untuk menempatkan deskripsi setelah // # wilayah kata kunci ala C # dan menunjukkannya dalam kode seperti yang ditunjukkan:
Kode contoh:
//#region InputHandler
var InputHandler = {
inputMode: 'simple', //simple or advanced
//#region filterKeys
filterKeys: function(e) {
var doSomething = true;
if (doSomething) {
alert('something');
}
},
//#endregion filterKeys
//#region handleInput
handleInput: function(input, specialKeys) {
//blah blah blah
}
//#endregion handleInput
};
//#endregion InputHandler
Makro Diperbarui:
Option Explicit On
Option Strict On
