Question

JSP如何返回上一页

Answer 1

onclick="javascript:window.location='<%=ref%'"
1.struts Ation中的用法：
Jsp获取上一页的url
String url=request.getHeader("Referer");返回上一页
mapping.findForward(url);
2.利用javascript
public String jump( String jump){
String url=null;
if(jump=="back"){
url="javascript:history.go(-1);\n"; //返回上一页}
else if(jump=="home"){
url="javascript:window.location.href='index.jsp';\n";//返回首页}
else if(jump==""){url="";}else{
url="javascript:window.location.href='"+jump+"';\n";
/返回指定页}
