This article mainly introduces the use of HTML's form form and the internal tags of the form. Friends in need can refer to the

code as follows:

<html> 
<head> 
<title> form表单的使用 </title> 
<!-- 
标签名称:form 表单标签 
属性:action:提交的去向,目标地址的url 
method:设置提交请求的方式,get和post;默认为get 
get和post提交有什么区别?------------------------ 
get传输:将内容信息放在地址栏传输,而且长度限制在1k,而且安全性不好。 
post传输:将内容房子body信息中传输。没有长度限制。 
子标签: 
input标签:需要提交其中的value,必须有一个name属性。 
属性:type:password 等 
//------------ 
通过下面的实例的演示,发现在某些情况下可以用form去做链接,而且做链接的同时还能提交数据到 
这个目标的地址文件上。 
fieldset标签:定义域 
legend标签:定义域的标题
