Hello, my JavaScript code is getting messy. I think it would be better organize if I use some Object Oriented techniques.

I also don't know how to combine jQuery event functions with JavaScript functions so everything's neat and easy to read.

How can I accomplish this?

This is a code example:

var ESCAPE_KEY = 27;
var ENTER_KEY = 13;

var user_current_page = 1;
var user_pages_total = 1;

// List users
function load_user() { ... }

// Opens the add form
$(document).on("click", "#btnUserAddForm", function() { ... }

// Adds user
$(document).on("click", "#btnUserAdd", function() { ... }

// Show Edit Form
$(document).on("click", ".btnUserEditForm", function() { ... }

// Saves
$(document).on("click", "#btnUserSave", function() { ... }

// Ask for confirmation on delete
$(document).on("click", ".btnUserDelete", function() { ... }

// Deletes
function user_delete(UsrCod) { ... }

// Cancels add or update
$(document).on("click", "#btnUserCancel", function() { ... }

// Previous page
$(document).on("click", "#btnUserPrevious", function() { ... }

// Next page
$(document).on("click", "#btnUserNext", function() { ... }

// Enter on search field
$(document).on("keyup", "#txtUserSearch", function(event) { ... }

Open in new window


Thanks!
