  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>

  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。
