Vue.js 模态组件显示在组件列表中，但模态实际上并未显示

Question

我试图在单击按钮时显示项目详细信息，我已将数据正确转到模态，但我似乎无法让模态实际显示。我在模板中尝试了不同的模态实现，我得到的关闭是在按钮按下时出现灰色屏幕。我现在不知道该怎么做，因为我在模态上尝试的每个教程似乎都不适合我。我正在使用 VUE CLI 版本 2

主页.vue

<template>
  <div class="home">
    <Navbar />
    <Ordertiles @childToParent="onClickChild"/>
    <div v-if="showModal">
    <Modal @close="toggleModal" :header="item.header" :text="item.text" :image="item.img"/>
    </div>
  </div>
</template>

<script>
// @ is an alias to /src
import Navbar from '@/components/Navbar.vue'
import Ordertiles from '@/components/Ordertiles.vue'
import Modal from '@/components/Modal.vue'

export default {
  name: 'Home',
  components: {
    Navbar,
    Ordertiles,
    Modal
  },
  data() {
    return {
      item: '',
      showModal: false
    }
  },

  methods: {
    toggleModal() {
      this.showModal = !this.showModal
    },
    onClickChild(item) {
      this.item = item
      console.log(this.item)
      this.toggleModal()
    }
  }
}
</script>

Modal.vue

<template>
  <div class="modal">
    <div class="container">
      <div class="modal__title">Direction</div>
      <p>{{header}}</p>
      <img v-bind:src="image"> 
      <p> {{text}} </p>
      <button class="mt-3 border-b border-teal font-semibold">Close</button>
    </div>
  </div>
</template>

<script>

export default {
  props: ['header', 'text', "image"],
  methods: {
    close () {
      this.$emit('close')
    }
  }
}
</script>

<style lang="css" scoped>
  .modal {
    background-color: rgba(0, 0, 0, 0.7);
  }
</style>

Answer 1

为什么不使用其他 npm modal 包，如 vue-modality 。我强烈保证这个包。它易于使用和理解。这将为您节省大量时间，因为您无需重新发明轮子。查看此链接https://www.npmjs.com/package/vue-modality

我找到了一个真正适合我的模态示例

Modal.vue

<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 {
  props: ['header', 'text', "image"],
  methods: {
    close () {
      this.$emit('close')
    }
  },
  components: {
  }
}
</script>

<style lang="css" scoped>
  .modal-mask {
  position: fixed;
  z-index: 9998;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  background-color: rgba(0, 0, 0, 0.5);
  display: table;
  transition: opacity 0.3s 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, 0.33);
  transition: all 0.3s 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;
}

.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);
}
