uploadnews.jsp

<%@ page language="java" contenttype="text/html; charset=utf-8"
 pageencoding="utf-8"%>
<!doctype html public "-//w3c//dtd html 4.01 transitional//en" "http://www.w3.org/tr/html4/loose.dtd">

<script language="javascript">

 .getelementbyid("content").value;
 document.getelementbyid("formid").submit();
 }
</script>
</head>
<body>
 <form method="post" action="shangchuannews.jsp" id="formid">
  <table border="0" align="center">

換行函數(shù)在shangchuannews.jsp 代碼如下

<%@page import="java.io.printwriter"%>
<%@page import="java.net.urldecoder"%>
<%@ page language="java" contenttype="text/html; charset=utf-8" 
 pageencoding="utf-8" %> 
<%@ page import="java.sql.*" %> 
<!doctype html public "-//w3c//dtd html 4.01 transitional//en" "http://www.w3.org/tr/html4/loose.dtd"> 

<html> 
<head> 
<meta http-equiv="content-type" content="text/html; utf-8"> 
<title>上傳新聞</title> 
</head> 
<body> 
<%! // 字符處理函數(shù) 換行符變成<br>
public string turn(string str) { 
 while (str.indexof("\n") != -1) { 
  str = str.substring(0, str.indexof("\n")) + "<br>" 
    + str.substring(str.indexof("\n") + 1); 
 } 
 while (str.indexof(" ") != -1) { 
  str = str.substring(0, str.indexof(" ")) + "&nbsp" 
    + str.substring(str.indexof(" ") + 1); 
 } 
 return str; 
} 
%>
<% 
try {
 request.setcharacterencoding("utf-8");
 string title = request.getparameter("title");
 string author = request.getparameter("author");
 string article = request.getparameter("articlename");
 string articlebr = turn(article);
 string date = request.getparameter("date");
 string driverclass="com.mysql.jdbc.driver";
 string url = "jdbc:mysql://****.****/****?characterencoding=utf8";//存到數(shù)據(jù)庫(kù)不會(huì)亂碼
 string user="***";

 connection conn;

 class.forname(driverclass).newinstance();
 conn = drivermanager.getconnection(url,user,password);
 string sql = "insert into news (id,title,author,article,date) "
   + "values(?,?,?,?,?)";
