　　html的表单标签是一个系列，用开闭的

标签包裹起来的组合。表单的作用是将我们要向服务器提交数据的数据包含起来，然后提交到服务器处理。（使用表单是浏览器提交客户端数据到服务端的方法之一，其它的方法涉及到asp.net技术）。

代码演示

 1 <html> 2     <head></head> 4     <body> 5     　　<form action="" method="post"> 6         　　<input type="text" name="name" value="" /> 7         　　<input type="submit" /> 8     　　</form> 9     </body>10 </html>

Copy after login

　　在form标签中文本框使用，提交按钮的input（输入）标签，如果要将数据提交到服务器，数据就要以键值对的形式处理，在输入标签中一定有name属性和value属性，组成"name:value"的形式。

运行结果

属性

　　form标签的action属性指明要将数据提交到的地址（即上面点击提交查询按钮后，接收提交的数据的地方）

　　method属性值分为get和post两种请求方法,get请求发送方式是将数据作为参数添加到请求的URL中，即在?后面以键值对的形式发送到请求地址。但这种方式所能发送的数据量有限，所以，当数据较大时采用post方法，将数据添加到发送报文中。
