============JavaScript函数====================
//功能：在URL中传递时 对URL中的特殊字符进行编码
<SCRIPT language="javascript">
window.alert("1");
var URLstr="sdl#kn";
var c;
var str="";
for(var i=0;i<URLstr.length;i++)
{
window.alert(i);
c = URLstr.charAt(i);
switch(c)
{
case ' ': str+=escape(" "); break;
case '#': str+=escape("#"); break;
case '%': str+=escape("%"); break;
case '&': str+=escape("&"); break;
window.alert(i+"haha");
//字符相加
default: str+=c;
window.alert(str);
}
}
</SCRIPT>
===========获得服务器上文件路径=================
//取得服务器的ip地址
javax.servlet.http.HttpServletRequest.getServerName()
//取得服务器端口
javax.servlet.http.HttpServletRequest.getServerPort()
//当前的工作路径 例如：C:/eclipse/workspace/CoalIndustry
javax.servlet.http.HttpServletRequest.getSession().getServletContext().getRealPath("");
===========根据文件类型设置不同方式=============
String fileName="test.doc";
String contents="contentType/octet-stream";
contents=this.findFilePostfix(fileName)
response.setContentType(contents);
//查询后缀名
public String findFilePostfix(String fileName)throws Exception
{
String contentType="contentType/octet-stream";
try
{
String filePostfix=fileName.substring(fileName.lastIndexOf(".")+1,fileName.length());
if(filePostfix.equals("txt"))
{
contentType="text/plain";
_log.warn("contentType::>>"+contentType);
}
if(filePostfix.equals("html")||filePostfix.equals("htm"))
{
contentType="text/html";
_log.warn("contentType::>>"+contentType);
}
if(filePostfix.equals("doc"))
{
contentType="application/msword";
_log.warn("contentType::>>"+contentType);
}
if(filePostfix.equals("xls"))
{
contentType="application/vnd.ms-excel";
_log.warn("contentType::>>"+contentType);
}
if(filePostfix.equals("ppt"))
{
contentType="application/vnd.ms-powerpoint";
_log.warn("contentType::>>"+contentType);
}
if(filePostfix.equals("pdf"))
{
contentType="application/pdf";
_log.warn("contentType::>>"+contentType);
}
if(filePostfix.equals("jpg")||filePostfix.equals("gif")||filePostfix.equals("bmp")||filePostfix.equals("png")||filePostfix.equals("psd"))
{
contentType="image/"+filePostfix;
_log.warn("contentType::>>"+contentType);
}
}
catch(Exception e)
{
_log.warn("Exception::>>"+e.toString());
}
return contentType;
}
============设置打开方=================
String fileName=fwb.txt;
//表示在浏览器中打开
response.setHeader("Content-Disposition","inline;filename=/""+fileName+"/"");
//表示另存为
response.setHeader("Content-Disposition","attachment;filename=/""+fileName+"/"");
