使用

1、swich主體
switch-on 代表開啟,如需設定預設關閉,可設定為 switch-offthemeColor 是主題色,zoom 可設定swich的大小,調整 zoom 的值即可調整大小。

<span class="switch-on" themeColor="#39f" id="switch" style="zoom:1;"></span>

class新增 switch-disabled 可設定為禁用。

<span class="switch-on switch-disabled" themeColor="#39f" id="switch" style="zoom:1;"></span>

2、swich監聽
透過 switchEvent 事件監聽switch的切換狀態。

$(function(){
    switchEvent("#switch",
        function(){

            $('#status').text('開');
        },function(){

            $('#status').text('關');
        }
    );
}

3、設定狀態
透過 honeySwitch.showOn("#switch")honeySwitch.showOff("#switch") 來設定開關。
