CrBoy / jquery.keycode_event.js
Created May 12, 2013 08:30
可以讓 jQuery 綁定鍵盤事件時指定只對特定按鍵作用的小程式。 使用方式： 1. 引入 jQuery 後，引入此 js 檔 2. 在綁定事件時這樣寫： $(this).keypress(13)(handler); 其中 $(this) 可代換成任何 jQuery 物件，handler 則是一般用於事件的 callback function。在此範例中，僅有當按下的按鍵為 enter 時， handler 才會作用。
var extend_keyboard_event_with_keycode = function(original_event_name) {
var $fn_original = $.fn[original_event_name];
var keyboard_event_function_wrapper = function(keycodes, handler) {
return function(e) {
if(keycodes.indexOf(e.which) != -1)
return handler(e);
}
}
