解决IE下返回json数据提示文件保存到问题

//发送的是JSON
public static void renderJson(HttpServletResponse response,String text){
render(response, "application/json;charset=UTF-8", text);
}
改为
//发送text
public static void renderText(HttpServletResponse response,String text){
render(response, "text/plain;charset=UTF-8", text);
}

//前段接收
success : function(result) {
//将text拼接为json
var result = eval('(' + result + ')');
if (result.message== 'ok') {

}else{

}
}
