废话不多说直接上代码:

<head>
<script src="<%=request.getContextPath()%>/UiFramework/jquary/jquery.min.js"></script>
</head>
<script>
(function ($) {

var Haorooms = function (el, opt) {
this.$element = el;
this.defaults = {
'color': 'red',
'fontSize': '12px',
'textDecoration': 'none'
};
//$.extend 自己查看jquery手册,这里简单的理解就是将 this.defaults赋值给{},
// 然后在将opt赋值给{}(如果已经存在将会被覆盖),然后返回{}
this.options = $.extend({}, this.defaults, opt)
};
//给Haorooms动态添加方法
Haorooms.prototype = {
changecss: function () {
return this.$element.css({
'color': this.options.color,
'fontSize': this.options.fontSize,
'textDecoration': this.options.textDecoration
});
}
};
$.fn.myPlugin = function (options) {
//创建haorooms的实体
var haorooms = new Haorooms($(this), options);
//调用其方法
haorooms.changecss();
}
})(jQuery);
</script>

<body>
<a id="11">11</a>
<a id="22">22</a>
<script>
$(function () {
$('#11').myPlugin({
color: '#000000',
fontSize: '50px'
});
})
</script>
</body>

结果:

11 22
