Bootstrap 模态隐藏 VUE 方法

Car*_*osa 3 vue.js bootstrap-4 vuejs2

我有一个 vuejs 组件,它显示一个带有小表单的模式对话框。提交表单后,我想隐藏模态,但不知道该怎么做。提交时,表单调用父级中的方法。

这是组件代码

<template>
  <div>
    <div id="todoModal" class="modal fade" role="dialog">
      <div class="modal-dialog">
        <div class="modal-content">
          <div class="modal-header">
            <h4 class="modal-title">{{ title }}</h4>
            <button type="button" class="close" data-dismiss="modal">
              &times;
            </button>
          </div>
          <div class="modal-body">
            <form id="todoForm" @submit.prevent="$emit('save')">
              <div class="form-group">
                <label for="name">Todo name</label>
                <input
                  id="name"
                  v-model="todo.name"
                  type="text"
                  class="form-control"
                  aria-describedby="nameHelp"
                  placeholder="Enter Todo Name"
                />
                <small id="nameHelp" class="form-text text-muted"
                  >Enter your todo's name</small
                >
              </div>
            </form>
          </div>
          <div class="modal-footer">
            <button class="btn btn-primary mr-4" type="submit" form="todoForm">
              <span v-if="mode == 'create'">Create</span>
              <span v-if="mode == 'update'">Update</span>

              class="btn btn-danger mr-auto"
              data-dismiss="modal"
              @click="
                $parent.showModal = false;
                $parent.getTodos();
              "
            >
              Cancel
            </button>
          </div>
        </div>

这是我的 APP.js 文件

<template>
  <div id="app" class="container mt-5">
    <router-view
      ref="createtodo"
      class="CreateTodo"
      name="a"
      :todo="todo"
      :title="title"
      :mode="mode"
      :show-modal="showModal"
      @save="saveTodo"
    ></router-view>
  </div>
</template>

<script>
import { APIService } from "./APIServices";
const apiService = new APIService();

export default {
  name: "App",
  data: function() {
    return {
      mode: "create",
      title: "Create Todo",
      todo: {},
      todos: [],
      numberOfTodos: 0,
      showModal: false
    };
  },
  mounted: function() {
    this.getTodos();
  },

  methods: {
    saveTodo: function() {
      if (this.mode == "create") {
        apiService.createTodo(this.todo).then(
          result => {
            if (result.status === 200) {
              this.todo = result.data;
              this.getTodos();
            }
          },
          error => {}
        );
        this.showModal = false;
        // this.$refs.createtodo.$refs.todoModal
      } else if (this.mode == "update") {
        apiService.updateTodo(this.todo).then(
          result => {
            this.getTodos();
          },
          error => {}
        );
        this.showModal = false;
      } else if (this.mode == "update") {
        apiService.updateTodo(this.todo).then(
          result => {
            this.showModal = false;
            this.getTodos();
          },
          error => {}
        );
      }
    },
  }
};
</script>

我尝试使用 ref 从 APP.js 引用 Modal,但它不起作用。

添加一个 id 到关闭 X 按钮”

<button type="button" class="close" data-dismiss="modal" aria-label="Close" id="close">
   <span aria-hidden="true">&times;</span>
</button>

然后创建一个方法来关闭模态框:

closeModal() {
   document.getElementById('close').click();
},

就像 @Dan Stoian 回复一样,您可以在 vue.js 中使用 ref :

<button ref="Close" type="button" data-dismiss="modal" ...>
   ...
</button>

在你的处理程序中

this.$refs.Close.click();

如果您使用的是 boostrap,则需要从中调用 hide 和 show 方法,因为 modal api 会动态创建 html 元素(作为深色背景)

我建议创建一个保存方法而不是调用 $emit,您可以在发出保存信号之前调用模态隐藏方法。

<script>
import $ from 'jquery'

export default {
  name: "CreateTodo",
  props: ["mode", "title", "todo"],
  ref: "createTodoModal",
  mounted() {
    if (this.mode == "create") {
      this.title = "Create Todo";
    }
  },
  methods: {
    save() {
       $('#ModalId').modal('hide')
       this.$emit('save')
    }
  }
};
</script>

在这种情况下不需要 showModal。
