Question

我在Vue JS中创建了一个模态组件。它必须显示表单中键入的所有名称。它不起作用。我能做些什么来解决这个问题？我是Vue JS的新人。我也不能使用短线。你知道为什么吗？请帮我。先感谢您。这是我的代码：

<template>
  <div class="template_class">
  <div>
  <b-btn v-b-modal.modal1>Launch demo modal</b-btn>

  <!-- Main UI -->
  <div class="mt-3 mb-3">
    Submitted Names:
    <ul>
      <li v-for="n in names">{{n}}</li>
    </ul>
  </div>

  <!-- Modal Component -->
  <b-modal id="modal1" title="Submit your name" @ok="submit" @shown="clearName">

    <form @submit.stop.prevent="submit">
      <b-form-input type="text" placeholder="Enter your name" v-model="name"></b-form-input>
    </form>

  </b-modal>
</div>  
  </div>
</template>

<script>

export default {
  data: {
    name: '',
    names: []
  },
  methods: {
    clearName() {
        this.name = '';
      },
      submit(e) {
        if (!this.name) {
          alert('Please enter your name');
          return e.cancel();
        }

        this.names.push(this.name);
        this.name = '';
      }
  }
}

</script>

<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>

</style>

您的代码对我没有任何意义，这是来自vue主页https://vuejs.org/v2/examples/modal.html

的一个很好的可重用示例

此代码直接从示例中复制，我只将其引用为单个文件组件：

<template>
  <transition name="modal">
    <div class="modal-mask">
      <div class="modal-wrapper">
        <div class="modal-container">

          <div class="modal-header">
            <slot name="header">
              default header
            </slot>
          </div>

          <div class="modal-body">
            <slot name="body">
              default body
            </slot>
          </div>

          <div class="modal-footer">
            <slot name="footer">
              default footer
              <button class="modal-default-button" @click="$emit('close')">
                OK
              </button>
            </slot>
          </div>
        </div>
      </div>
    </div>
  </transition>
</template>

<script>
export default{
  name: 'modal'
}
</script>

<style>
.modal-mask {
  position: fixed;
  z-index: 9998;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  background-color: rgba(0, 0, 0, .5);
  display: table;
  transition: opacity .3s ease;
}

.modal-wrapper {
  display: table-cell;
  vertical-align: middle;
}

.modal-container {
  width: 300px;
  margin: 0px auto;
  padding: 20px 30px;
  background-color: #fff;
  border-radius: 2px;
  box-shadow: 0 2px 8px rgba(0, 0, 0, .33);
  transition: all .3s ease;
  font-family: Helvetica, Arial, sans-serif;
}

.modal-header h3 {
  margin-top: 0;
  color: #42b983;
}

.modal-body {
  margin: 20px 0;
}

.modal-default-button {
  float: right;
}

/*
 * The following styles are auto-applied to elements with
 * transition="modal" when their visibility is toggled
 * by Vue.js.
 *
 * You can easily play with the modal transition by editing
 * these styles.
 */

.modal-enter {
  opacity: 0;
}

.modal-leave-active {
  opacity: 0;
}

.modal-enter .modal-container,
.modal-leave-active .modal-container {
  -webkit-transform: scale(1.1);
  transform: scale(1.1);
}
</style>

我在Vue.js中创建了一个不起作用的模态组件
