Python全栈开发之16、jquery

一、查找元素

1、选择器

1.1 基本选择器 $("*") $("#id") $(".class") $("element") $(".class,p,div")

1.2层级选择器 $(".outer div")(所有的后代) $(".outer>div")(所有的子代) $(".outer+div")(匹配所有跟在.outer后面的div)

　　　　　　　　　　 $(".outer~div")(.outer后面的所有div)

1.3 基本筛选器 $("li:first") $("li:eq(2)") $("li:even")(偶数) $("li:gt(1)")

1.4 属性选择器 $('[id="div1"]') $('["alex="sb"][id]')

1.5 表单选择器 $("[type='text']") 简写成 $(":text") 注意只适用于input标签

2 筛选器

2.1 过滤筛选器

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

2.2 查找筛选器

$("div").children(".test")(只考虑子元素，而不考虑所有的后代) $("div").find(".test") (考虑所有的后代)

$(".test").next() $(".test").nextAll() $(".test").nextUntil() (开区间)

$("div").prev() $("div").prevAll() $("div").prevUntil()

$(".test").parent() $(".test").parents()(祖先元素集合) $(".test").parentUntil()

$("div").siblings() (同辈元素不包括自己)

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',backgroud:'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 height()不包含边框

3 文档处理

内部插入 $("#c1").append("<b>hello</b>") $("p").appendTo("div")

prepend() prependTo()

外部插入 before() insertBefore() after() insertAfter()

replaceWith() remove() empty() clone()

4 事件

4.1

$(document).ready(function(){}) -----------> $(function(){}) 最好都加上这一句(所有文档执行完，但是图片没加载)

4.2

$("p").click(function(){})

$("p").bind("click",function(){})

$("ul").delegate("li","click",function(){})　　// 事件委托，这里需要重点注意下

三、jquery所有示例

        .outer {

<script>
    $(function () {

            $(this).addClass('active').siblings().removeClass('hide');
            $(this).parent().siblings().find('.con').addClass('hide');
            $(this).parent().siblings().find('.title').removeClass('active');

            //下面操作对应点击哪项菜单显示相应内容
            var con = $(this).attr('itemcon');
            $("#" + con).removeClass('hide').siblings().addClass('hide'); //为什么要拼接
        })
    });

</script>
</body>
