python基础-第十二篇-12.1jQuery基础与实例

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="http://www.mamicode.com/添加"/>    <script src="http://www.mamicode.com/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="http://www.mamicode.com/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="http://www.mamicode.com/IP">             </div>         </div>    </div> </div>    <script src="http://www.mamicode.com/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>
