var add = { template: "<div class='re-box'><div><span>姓名</span><input type='text' id='name' v-model='name'/></div>"+ "<div><span>月份</span><input type='number' id='month' v-model='month'/></div>"+ "<div><span>成交数</span><input type='number' id='dones' v-model='dones'/></div>"+ "<div><span>成交量</span><input type='number' id='doneCount' v-model='doneCount'/></div>"+ "<button id='add' @click='add'>提交</button></div>", data:function() { return { name:"", month:null, dones:null, doneCount:null } }, methods:{ add:function() { if(this.name == "" || this.month == null || dones == null || doneCount == null) { alert("内容不能为空"); return; } Vue.http.post(baseUrl+"/add/"+this.name+"/"+this.month+"/"+this.dones+"/"+this.doneCount).then(function(res){ var mes = res.body; if(mes == "exist") { alert("数据已存在"); } else if(mes == "success") { alert("提交成功"); alert(this.name); } },function(res){ console.log(res.status); }); } }};then方法以外的this调用正常，为什么then里面的this调用就不对呢？
