jQuery 抄袭笔记(5) : Html(),Show()

  1. 无参html():取得第一个匹配元素的html内容。这个函数不能用于XML文档。但可以用于XHTML文档,返回的是一个String

html页面代码:<div><p>Hello</p></div>

jquery代码:$(“div”).html();

结果:Hello
2.有参html(val):设置每一个匹配元素的html内容。这个函数不能用于XML文档。但可以用于XHTML文档。返回一个jquery对象

html页面代码:<div></div>

jquery代码:$(“div”).html(“<p>Nice to meet you</p>”);

结果:[ <div><p> Nice to meet you</p></div> ]

3.show():该效果适用于通过 jQuery 隐藏的元素,或在 CSS 中声明 display:none 的元素(但不适用于 visibility:hidden 的元素)。
