Question

我使用https://santiblanko.github.io/vue-instant/来自动完成Vue。

它可以按我预期的方式工作，除了我无法将“ input”值内的值发布到表单上。

提交表单时，输入中的值不会发布到我的后端服务器上。

所以提交时我必须创建一个隐藏值，以便我可以读取该输入值。

如何执行此操作。我只希望在单击放大镜图标时提交表单和值。

Answer 1

如果我理解正确，是否要将建议值发布到表单数据对象内的服务器？如果是正确的话，您可以按以下方式更改clickButton方法。

clickButton: function() {
      this.selectedEvent = 'click button';
      var formData = new FormData();
      formData.append("selectedMovie", this.value);
      axios({
        method: 'post',
        url: '/yourapi/endpoint/',
        data: {
          formData:formData
        }
      }).then(function(response) {
        console.log(response.data);
        console.log(response.status);
        console.log(response.statusText);
      });
    }

Answer 2

您可以将以下内容添加到表单元素v-on:submit.prevent="send"的html中。然后将send函数添加到组件的方法中，在这些方法中，您可以访问this.value并执行所需的操作。

将自动完成输入值获取到隐藏的输入Vue.Js
