你

servlet的头定义response.setContentType("application/json");

像

StringBuffer sb=new StringBuffer(); 
      sb.append("["); 
      if(rs1.next()){ 
       sb.append("{"); 
       sb.append("\"country\": \"CH\","); 
       sb.append("\"visits\":\""+rs1.getString(1)+"\","); 
       sb.append("\"color\":\""+"#FF0F00"+"\""); 
       sb.append("},"); 
       sb.append("{"); 
       sb.append("\"country\": \"USA\","); 
       sb.append("\"visits\":\""+rs1.getString(2)+"\","); 
       sb.append("\"color\":\""+"#FF6600"+"\""); 
       sb.append("},"); 
       sb.append("{"); 
       sb.append("\"country\": \"UK\","); 
       sb.append("\"visits\":\""+rs1.getString(3)+"\","); 
       sb.append("\"color\":\""+"#FF9E01"+"\""); 
       sb.append("},"); 
       sb.append("{"); 
       sb.append("\"country\": \"AU\","); 
       sb.append("\"visits\":\""+rs1.getString(4)+"\","); 
       sb.append("\"color\":\""+"#FCD202"+"\""); 
       sb.append("},"); 
       sb.append("{"); 
       sb.append("\"country\": \"DK\","); 
       sb.append("\"visits\":\""+rs1.getString(5)+"\","); 
       sb.append("\"color\":\""+"#F8FF01"+"\""); 
       sb.append("},"); 
       sb.append("{"); 
       sb.append("\"country\": \"PK\","); 
       sb.append("\"visits\":\""+rs1.getString(6)+"\","); 
       sb.append("\"color\":\""+"#B0DE09"+"\""); 
       sb.append("},"); 
       sb.append("{"); 
       sb.append("\"country\": \"ML\","); 
       sb.append("\"visits\":\""+rs1.getString(7)+"\","); 
       sb.append("\"color\":\""+"#04D215"+"\""); 
       sb.append("},"); 
       sb.append("{"); 
       sb.append("\"country\": \"JP\","); 
       sb.append("\"visits\":\""+rs1.getString(8)+"\","); 
       sb.append("\"color\":\""+"#0D8ECF"+"\""); 
       sb.append("},"); 
       sb.append("{"); 
       sb.append("\"country\": \"IN\","); 
       sb.append("\"visits\":\""+rs1.getString(9)+"\","); 
       sb.append("\"color\":\""+"#0D52D1"+"\""); 
       sb.append("},"); 
       sb.append("{"); 
       sb.append("\"country\": \"TW\","); 
       sb.append("\"visits\":\""+rs1.getString(10)+"\","); 
       sb.append("\"color\":\""+"#2A0CD0"+"\""); 
       sb.append("}"); 


       } 
      sb.append("]"); 

然后做out.write(sb.toString());

然后在HTML文件中获取从请求对象数据var test=JSON.parse(xmlhttp.responseText);

记得我创建JSON格式的数据在此使用Ajax ....
