一、查找元素

1、选择器

　　基本选择器

$("*")
$("#id")
$(".class")
$("element")
$(".class,p,div")

　　层级选择器

$(".outer div") 后代
$(".outer>div") 子代
$(".outer+div") .outer后面的兄弟div（后面一个）
$(".outer~div") .outer后面的所有的兄弟div

　　基本筛选器

$("li:first")
$("li:eq(2)")
$("li:even")
$("li:gt(1)")

　　属性选择器

$("[id=‘div1‘]")
$("[alex=‘sb‘][id]")

　　表单选择器

$("[type=‘text‘]") 简写成$("：text")--只适用于input标签

2、筛选器

　　过滤筛选器

$("li").eq(2)
$("li").first()
$("ul li").hasclass("test") 检测li中是否含有某个特定类，有的话返回true

　　查找筛选器

$("div").children(".test") 找儿子
$("div").find(".test") 子子孙孙
$(".test").next() $(".test").nextAll() $(".test").nextUntil() (开区间)
$("div").prev() $("div").prevAll() $("div").prevUntil()
$(".test").parent() $(".test").parents() 找祖先元素集合 $(".test").parentUntil()
$("div").siblings（）同辈（不包括自己）

二、操作元素

1、属性操作

$("p").text() $("p").html() $(":checkbox").val()
$(".test").attr("alex") $(".test").attr("alex","sb")
$(".test").attr("checked","checked") $(":checkbox").removeAttr("checked")
$(".test").prop("checked","true")
$(".test").addClass("hide")

2、css操作

（样式） css（“{color:"red",background:"blue"}”）
(位置） offset（） position（） scrollTop（） scrollLeft（）
（尺寸） innerHeight（）不包含边框 outerHeight（）包含边框，两个都包含padding

3、文档处理

　　内部插入

$("#id").append("<b>hello</b>") 在id标签内添加hello内容
$("p").appendto("div") 把p标签添加到div标签内
prepend（） prependto（）

　　外部插入

before() insertBefore()
after() insertAfter()
replaceWith()
remove() 移除标签
empty() 清空内容，标签保留
clone 克隆（用于批量处理）

4、事件

$(document).ready(function(){})======$(function(){}) 最好加上这句，所有文档执行完，但是图片没加载
$("p").click(function(){}) 内部是调用了jQuery的bind方法--事先绑定
$("p").bind("click",function(){}) 事先绑定
$("ul").delegate("li","click",function(){}) 事件委托（事中绑定）

<body>
    <ul>
        <li>11</li>
        <li>33</li>
        <li>66</li>
        <li>46</li>
    </ul>
    <input type="text"/>
    <input id="li" type="button" value="添加"/>
    <script src="jquery-1.8.2.js"></script>
    <script type="text/javascript">
        $("ul").delegate("li","click",function(){
            console.log(this);
        })
        $("#li").click(function(){
            var txt = $(this).prev().val();
            $("ul").append("<li>"+txt+"</li>");
        })
    </script>
</body>

三、jQuery常见实例

拖动面板

<body>
     <div style="border: 1px solid #ddd;width: 600px;position: absolute;">
         <div id="title" style="background-color: black;height: 40px;color: white;">
            标题
        </div>
         <div style="height: 300px;">
            内容
        </div>
     </div>



    <script src="jquery-1.8.2.js"></script>
    <script type="text/javascript">
        $("#title").mouseover(function(){
            $(this).css("cursor","move");
        }).mousedown(function(e){
            var _event = e||window.event;
            var old_x = _event.clientX;
            var old_y = _event.clientY;

            var parent_left = $(this).parent().offset().left;
            var parent_top = $(this).parent().offset().top;

            $(this).mousemove(function(e){
                var _new_event = e||window.event;
                var new_x = _new_event.clientX;
                var new_y = _new_event.clientY;

                var x = new_x - old_x + parent_left;
                var y = new_y - old_y + parent_top;

                $(this).parent().css({"left":x+"px","top":y+"px"});
            }).mouseup(function(){
                $(this).unbind("mousemove");
            })
        })
    </script>
</body>

clone内容添加与删除

<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
         .inline {
             display: inline-block;
         }
     </style>
 </head>
 <body>
 <div class="container">
     <div class="section">
         <div class="button inline">
             <a id="origin">
                 <button>+</button>
             </a>
             <div class="input inline">
                 <input type="checkbox">
                 <input type="text" value="IP">
             </div>
         </div>
    </div>
 </div>


    <script src="jquery-1.8.2.js"></script>
    <script type="text/javascript">
        $(function(){
            $("#origin").click(function(){
                var origin = $(this).parent().parent().clone();
                origin.find("a").removeAttr("id").attr("onclick","myremove(this);").children().text("-");
                $(".container").append(origin);
            })
        })
        function myremove(self){
            console.log("123");
            $(self).parent().parent().remove();
        }
    </script>
</body>

滑动

    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        #flipshow,#content,#fliphide,#toggle{

    <script src="jquery-1.8.2.js"></script>
    <script>
        $(document).ready(function(){
              $("#flipshow").click(function(){
                 $("#content").slideDown(1000);
              });
              $("#fliphide").click(function(){
