jQuery插件的开发包括两种:
(1)类级别的插件开发,即给jQuery添加新的全局函数,jQuery的全局函数就是属于jQuery命名空间的函数,相当于给jQuery类本身添加方法。

大佬的总结经验(第一个链接):
(1)把全部代码放在闭包中(闭包相当于一个私有作用域,外部无法访问到内部的信息,并且不会存在全局变量的污染情况)
(2)提供插件的默认参数选项
(3)遍历多个元素并返回(Sizzle选择器引擎,链式调用)
(4)一次性代码放在主循环外
(5)定义公有方法和私有方法(增加代码的健壮性)
(function($) {
// 在插件容器内,定义一个私有方法
var privateFunction = function() {
// code here
}; // 通过字面量创造一个对象,存储我们需要的共有方法
var methods = {
// code here
}; })(jQuery);
(6)添加持久性数据($.data函数为元素添加信息),$.removeData函数来删除相应的数据
