HTML5每日一练之details展开收缩标签的应用

details标签的出现,为我们带来了更好的用户体验,不必为这种收缩展开的效果再编写JS来实现。
注:目前仅Chrome支持此标签。

details有一个新增加的子标签——summary,当鼠标点击summary标签中的内容文字时,details标签中的其他所有元素将会展开或收缩。
detalis标签:
案例1:

<!DOCTYPE HTML> 
<html> 
    <head> 
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> 
        <title>HTML5每日一练之details展开收缩标签的应用</title> 
    </head> 
    
    <body> 
        <details> 
      <summary>HTML5|CSS3|论坛 | 前端开发网(W3Cfuns.com)!</summary> 
    <p>HTML5论坛,CSS3论坛,CSS论坛,WEB前端开发论坛,教程资源完全免费的CSS论坛,打造最好的HTML5/CSS3论坛</p> 
        </detalis> 
    </body> 
</html>
Copy after login

如果details中不存在summary标签会怎样呢,其实当details元素内没有summary标签的时候,浏览器在解析的时候会提供一个默认的文字,比如“查看详细”诸如此类的本地化文字,浏览器同样再会提供一个诸如上下箭头之类的图标。比如下面的案例2就是一个不存在summary子标签的例子。
案例2:

<!DOCTYPE HTML> 
<html> 
    <head> 
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> 
        <title>HTML5每日一练之details展开收缩标签的应用</title> 
    </head> 
    
    <body> 
        <details> 
  <p>HTML5论坛,CSS3论坛,CSS论坛,WEB前端开发论坛,教程资源完全免费的CSS论坛,打造最好的HTML5/CSS3论坛</p> 
        </details> 
    </body> 
</html>
Copy after login


有的时候,我们需要detalis中的内容默认为展开状态怎么办?
其实HTML5也已经为我们想到了,如果有着方面的需求,我们只需要加入一个属性即可,如案例3。
Open属性:
将案例1的代码修改后如下:
案例3:

<!DOCTYPE HTML> 
<html> 
    <head> 
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> 
        <title>HTML5每日一练之details展开收缩标签的应用</title> 
    </head> 
    
    <body> 
        <details open> 
      <summary>HTML5|CSS3|论坛 | 前端开发网(W3Cfuns.com)!</summary> 
     <p>HTML5论坛,CSS3论坛,CSS论坛,WEB前端开发论坛,教程资源完全免费的CSS论坛,打造最好的HTML5/CSS3论坛</p> 
        </details> 
    </body> 
</html>
Copy after login
