// jQuery的$函数的用法:
// 1. 如果$函数的参数是一个函数那么这个函数是文档加载完成之后要执行的回调函数
// 2. 如果$函数的参数是选择器字符串那么$函数会返回代表对应的标签的jQuery对象
// 3. 如果$函数的参数是一个原生JavaScript对象那么$函数会返回与之对应的jQuery对象
// 4. 如果$函数的参数一个标签字符串那么$函数会创建对应的元素而且返回jQuery对象
// 原生的JS对象和jQuery对象如何实现转换?
// $(原生JS对象) ---> jQuery对象
// jQuery对象.get(index) / jQuery对象[index] ---> JS对象
// 注: jQuery对象的本质是一个数组
