This article is summarized in daily work. The four forms of parameter transfer are shown below.

When to use GET, search, delete,

When to use POST, add, change (Special: use POST to log in, because the username and password cannot be displayed on the URL)

4 ways to get parameters

<html xmlns="http://www.w3.org/1999/xhtml"> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> 
 <title></title> 
 <script type="text/javascript"> 
  function Go() { 
   window.location.href="localhost:21811/Handler1.ashx&#63;id=1&name='abc'" 
  } 
 </script> 
</head> 
<body>
Copy after login


Copy code The code is as follows:

localhost:21811/Handler1.ashx?id=1&name="abc"




 

 <form action="Handler1.ashx" method="get"><!--注意action里面的连接不能带参数的-->> 
  <input type="text" name="id" value="3" /> 
  <input type="text" name="name" value="abc" /> 
  <input type="submit" value="通过传递参数" /> 
 </form> 
</body> 
</html>
Copy after login

Through the introduction of the above code, I believe everyone will like it.
