Example of using callback function

Excerpt:

Depending on how your plug-in is defined

$.fn.xtab = function(setting,callback)
xtab method should be able to receive two parameters: setting (configuration parameters) and callback (callback function).

So you should call it like this:
$(".element").xtab({}, function(){cosle.log('this is callback');});

If you want to use setting or other parameters and methods in the plug-in in the callback, you need to pass the parameters in when the callback is called:

$.fn.xtab = function(setting, callback){ var $this = $(this); // 将配置参数缓存在当前 jquery 对象上 $this.data('xtab-setting', setting); $this.data('xtab-callback', callback); // 假设点击时，调用 callback，并且传入配置参数 $this.click(function(){ callback($this.data('xtab-setting').value); }); }//调用： $('.p').xtab({value:'test'}, function(val){console.info(val);});

The above are just examples.
