Use examples to illustrate
Ashx and ASPX are two ways to handle foreground submission data:
Ashx
New/website1
Hello1.htm
<! DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 transitional//en" "Http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ">
<title></title>
<body>
<form action= "Hello1.ashx" >
Name: <input type= "text" value= "UserName" name= "UserName"/>
<input type= "Submit" value= "submitted"/>
<!--
The server only has the name attribute, and if the Name property repeats, it will only submit the first
ID is used for DOM
-->
</form>
</body>
---------------------------------------------------------------------------
Hello1.ashx
<%@ WebHandler language= "C #" class= "Hello1"%>
Using System;
Using System.Web;
public class Hello1:ihttphandler {
public void ProcessRequest (HttpContext context) {
Context. Response.ContentType = "Text/plain";//The Returned data is in TXT format
Writing plain here may result in the browser being recognized as XML
Context. Response.ContentType = "text/html";//indicates that the returned data is HTML
Write the original HTML to the browser:
String username = context. request["UserName"];//gets the HTML end, and returns the value of name UserName
Context. Response.Write (@ "<form action= ' hello1.ashx ' >
Name: <input type= ' text ' value= ' "+username+@" ' name= ' username '/>
<input type= ' Submit ' value= ' submitted '/>
</form> ");//write the original data into the control
Adding a @ In C # means multiple lines of text
Context. Response.Write ("Hello World");
Context. Response.Write (username);//write back to Browser
}
public bool IsReusable {
get {
return false;
}
}
}

Name: <input type= "text" value= "UserName" name= "UserName"/>
