# jquery中的live()方法在jquery1.9及以上的版本中已被废弃了，如果使用，会抛出`TypeError: $(...).live is not a function`错误。  解决方法：  之前的用法：  .live(events， function)  新方法：  .on(eventType, selector, function)  若selector不需要，可传入null  例子1：  之前：  $(‘\#mainmenu a’).live(‘click’, function)  之后：  $(‘\#mainmenu’).on(‘click’, ‘a’, function)  例子2：  之前：  $(‘.myButton’).live(‘click’, function)  之后(应使用距离myButton最近的节点)：  $(‘\#parentElement’).on(‘click’, ‘.myButton’, function)  若不知最近的节点，可使用如下的方法：  $(‘body’).on(‘click’, ‘.myButton’, function)      #
