前端之--Jquery-玩穿它!
一、 jquery简介
1 jquery是什么
- jQuery由美国人John Resig创建,至今已吸引了来自世界各地的众多 javascript高手加入其team。
- jQuery是继prototype之后又一个优秀的Javascript框架。其宗旨是——WRITE LESS,DO MORE,写更少的代码,做更多的事情。
- 它是轻量级的js库(压缩后只有21k) ,这是其它的js库所不及的,它兼容CSS3,还兼容各种浏览器 (IE 6.0+, FF 1.5+, Safari 2.0+, Opera 9.0+)。
- jQuery是一个快速的,简洁的javaScript库,使用户能更方便地处理HTML documents、events、实现动画效果,并且方便地为网站提供AJAX交互。
- jQuery还有一个比较大的优势是,它的文档说明很全,而且各种应用也说得很详细,同时还有许多成熟的插件可供选择。
- jQuery能够使用户的html页保持代码和html内容分离,也就是说,不用再在html里面插入一堆js来调用命令了,只需定义id即可。
2 什么是jQuery对象?
- jQuery 对象就是通过jQuery包装DOM对象后产生的对象。
- jQuery 对象是 jQuery 独有的. 如果一个对象是 jQuery 对象, 那么它就可以使用 jQuery 里的方法: $(“#test”).html();
比如:
$("#test").html() 意思是指:获取ID为test的元素内的html代码。其中html()是jQuery里的方法
这段代码等同于用DOM实现代码: document.getElementById(" test ").innerHTML;
虽然jQuery对象是包装DOM对象后产生的,但是jQuery无法使用DOM对象的任何方法,同理DOM对象也不能使用jQuery里的方法.乱使用会报错
约定:如果获取的是 jQuery 对象, 那么要在变量前面加上$.
var $variable = jQuery 对象
var variable = DOM 对象
基本语法:$(selector).action()
二 寻找元素(重要的选择器和筛选器)
2.1 选择器
2.1.1 基本选择器 $("*") $("#id") $(".class") $("element") $(".class,p,div")
2.1.2层级选择器 $(".outer div") $(".outer>div") $(".outer+div") $(".outer~div")
2.1.3 基本筛选器 $("li:first") $("li:eq(2)") $("li:even") $("li:gt(1)")
2.1.4 属性选择器 $('[id="div1"]') $('["alex="sb"][id]')
2.1.5 表单选择器 $("[type='text']")----->$(":text") 注意只适用于input标签
$("input:checked")
2.2 筛选器
2.2.1 过滤筛选器
$("li").eq(2) $("li").first() $("ul li").hasclass("test")
2.2.2 查找筛选器
$("div").children(".test") $("div").find(".test")
$(".test").next() $(".test").nextAll() $(".test").nextUntil()
$("div").prev() $("div").prevAll() $("div").prevUntil()
$(".test").parent() $(".test").parents() $(".test").parentUntil()
$("div").siblings()
