  for(StatusEnum status : StatusEnum.values()){
   statusDTO = new StatusDTO();
   statusDTO.setCode(status.toString());
   list.add(statusDTO);
  }
  return list;
 }

}
var selectVue = new Vue({
 el:'#selectStatus',// 绑定DOM,一般是绑定p
 data:statusModel //标签中使用的model
})
var selectStatusResource = Vue.resource('/status/getStatus').get().then(function (response) {
 var statusList = response.data;
 var list = [];
 var status = null;
 for(var i = 0; i < statusList.length; i++){
  status = statusList[i].code == &#39;RED&#39; ? &#39;红色&#39; : statusList[i].code == &#39;YELLOW&#39; ? &#39;黄色&#39; : statusList[i].code == &#39;GREEN&#39; ? &#39;绿色&#39; : &#39;&#39;;
  list.push({code:statusList[i].code,name:status});
 }
 statusModel.selectStatus = list;
});

 <p id="selectStatus" style="width:140px;height: 37px;text-align: right;margin: 0 2px;position: relative;float: left;">
   <select id="status" style="width:100%;background: #ddebff;height: 35px;color: #082451;
          border: 1px solid #082451;border-radius: 2px;font-size: 12px;
          box-shadow: 3px 3px 3px #96c0e7 inset;" v-model="status">
    <option value="-1">-请选择-</option>
    <option v-for="option in selectStatus" :value="option.code">{{option.name}}</option>
