前面的话

  HTML5不仅新增了语义型区块级元素及表单类元素,也新增了一些其他的功能性元素,这些元素由于浏览器支持等各种原因,并没有被广泛使用

文档描述

  

主要用于描述文档或文档某个部分的细节,与配合使用可以为
定义标题。标题是可见的,用户点击标题时,显示出details

  [注意]这两个标签只有chrome和opera支持

  该标签仅有一个open属性,用来定义details是否可见(默认为不可见状态)

<details>
    <summary>Copyright 2015.</summary>
    <p>php中文网</p>
</details>

对话框

  

标签用来定义对话框或窗口,且该对话框位于窗口的水平居中位置

  该标签只有一个open属性,用来定义对话框是否可见(默认为不可见)

  [注意]只有chrome和opera支持

<button>显示对话框</button>
<dialog>我是对话框的内容</dialog>
<script>
var oBtn = document.getElementsByTagName(&#39;button&#39;)[0];
var oDia = document.getElementsByTagName(&#39;dialog&#39;)[0]; 
oBtn.onclick = function(){
  console.log(oDia.getAttribute(&#39;open&#39;))
  if(!oDia.getAttribute(&#39;open&#39;)){
    oDia.setAttribute(&#39;open&#39;,&#39;open&#39;);
    this.innerHTML =&#39;隐藏文本框&#39;;
  }else{
    oDia.removeAttribute(&#39;open&#39;);
    this.innerHTML = &#39;显示文本框&#39;;
  }
}
</script>
Copy after login
