Bootstrap Modal Hide from VUE method

Question

I have a vuejs component that displays a modal dialog with a small form inside. When the form is submitted I would like to hide the Modal but cannot figure out how to do it. When submitted the form calls a method in the parent.

Here is the component code

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

<script>
export default {
  name: "CreateTodo",
  props: ["mode", "title", "todo", "showModal"],
  ref: "createTodoModal",
  mounted() {
    if (this.mode == "create") {
      this.title = "Create Todo";
    }
  },
  methods: {}
};
</script>
<style scoped></style>

And here is my APP.js file

<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>

<style lang="scss">
</style>

I tried using the ref to reference the Modal from APP.js but it does not work.

Answer 1

Add an id to the close X button"

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

Then create a method to close the modal:

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

Answer 2

If you are using boostrap, you need to call the hide an show methods from it, because modal api create html elements on the fly (as the dark background)

I recommend to create a save method instead of call the $emit, where you can call the modal hide method before emit the save signal.

<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>

showModal is not needed in this case.

Answer 3

Like @Dan Stoian reply, you can use ref in vue.js :

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

And in your handler

this.$refs.Close.click();

Answer 4

You might use v-if to show/hide modal

In your component:

  <div v-if="showModal">
    <div id="todoModal" class="modal fade" role="dialog">
    ...
    </div>
  </div>

and set showModal to true/false to show/hide component respectively.
