在ajaxSubmit提交表单的配置里面，增加一个参数，服务器端判断是否是ajaxSubmit提交过来的表单，是的话就返回“text/html”类型的内容，不是就可以返回“
application/json”的。
public void write(String msg,HttpServletResponse response) throws Exception {
PrintWriter write = null;
//response.setContentType("application/text;charset=UTF-8");
response.setContentType("text/html;charset=UTF-8");
response.setHeader("Pragma","No-cache");
response.setHeader("Cache-Control","no-cache");
response.setDateHeader("Expires",0);
try {
write = response.getWriter();
write.write(msg);
write.flush();
} catch (IOException e) {
throw new Exception("ajax write error" + e.getMessage());
} finally {
response = null;
if (write != null)
write.close();
write = null;
}
}
把文中注释的代码换成response.setContentType("text/html;charset=UTF-8")代码即可。
