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() $(":checkbox").val() 修改--在括号里添值$("#qq2").text("hello")
- $(".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>

})
})
function myremove(self){
console.log("123");
$(self).parent().parent().remove();
