ajax 执行成功不进success

 

    <div class="ft">
          <button class="cancel">取消</button>
          <button class="confirm"  onclick="submit1()">确认</button>
        </div>

@ResponseBody
    @RequestMapping("/addArea")

    public String  addArea(Model model,String sceneName,String location,String article,String gateid,String contents,String areaType){
        Scene scene = new Scene();
        scene.setScenename(sceneName);
        scene.setLocation(location);
        scene.setArticlename(article);
        scene.setGatewayid(Integer.valueOf(gateid));

        String scenetype1=areaType.substring(1,areaType.length()-2);
        scene.setScenetype(scenetype1);
}
        try {
            subService.addObj(scene);
        } catch (Exception e) {
            // TODO: handle exception
            return "error";
        }
        return "ok";
    }

 

当dataType: "JSON"时， 后台返回的是 ok 或者error 字符串 ，不是标准格式 ，因此不能进入success方法 只需改成 dataType: "text"
