// 写JavaScript代码时为什么推荐使用jQuery而不写原生JavaScript
|
||||
// 因为jQuery对象有更多的属性和方法, 能够用更少的代码做更多的事情
|
||||
// 而且jQuery对象的方法使用灵活且没有浏览器兼容性问题
|
||||
|
||||
// 当加载jQuery成功时会在window对象上绑定名为jQuery的属性
|
||||
// 该属性还有一个名字叫$, $既是一个对象也是一个函数
|
||||
// 当$作为函数时有以下四种最常用的用法:
|
||||
// 1. 如果$函数的参数是一个函数, 传入的函数是页面加载完成时要执行的回调函数
|
||||
// 2. 如果$函数的参数是选择器字符串, 那么$函数会返回代表元素的jQuery对象(其本质是一个数组)
|
||||
// 3. 如果$函数的参数是标签字符串, 那么$函数会创建该标签并返回对应的jQuery对象
|
||||
// 4. 如果$函数的参数是原生JavaScript对象(DOM), 那么$函数将该对象处理成jQuery对象
|
||||
|
||||
// 用法1
