我在 Vue 中有一个工作模式，但是，模式在页面加载的瞬间加载为空，我希望它保持完全隐藏（即使在页面加载时），直到单击按钮。

我在 CSS 中使用 display:none 进行了测试，它可以在页面加载时隐藏它，但是在按下按钮时它仍然完全隐藏。我试图通过将条件样式绑定到 div 来解决这个问题，但仍然没有运气。

如何通过单击按钮保持此模式的功能，同时允许它在页面加载时显示：无？

var vm = new Vue({
  el: "#app",
  props: {},
  data: {
    showDetailModal: false,
  },
  methods: {
    openModal() {
      console.log(this.showDetailModal);
      this.showDetailModal = true;
      console.log(this.showDetailModal);
    }
  },
});
.modal-vue .overlay {
  //display: none;
  text-align: center;
  position: fixed;
  z-index: 9998;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  background-color: rgba(0, 0, 0, .5);
}

.modal-vue .modal {
  //display: none;
  position: relative;
  width: 300px;
  z-index: 9999;
  margin: 0 auto;
  padding: 20px 30px;
  background-color: #fff;
}

.modal-vue .close {
  position: absolute;
  top: 10px;
  right: 10px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>

<div id="app">

  <div @click="openModal()">
    Open Modal
  </div>

  <div class="modal-vue" v-if="showDetailModal" :style="'display: ' + (showDetailModal ? 'block' : 'none')">
    <!-- overlay to help with readability of modal -->
    <div class="overlay" @click="showDetailModal = false"></div>

    <!-- Modal for detail on table cell click event -->
    <div class="modal" v-if="showDetailModal">
      <button class="close" @click="showDetailModal = false">x</button>
      <h3>Testing</h3>
    </div>
  </div>

</div>

我认为问题在于你改变:style="'display: ' + (showDetailModal ? 'block' : 'none')"了.modal-vue但在你的 CSS 中定义display: none了.modal-vue .modal.

所以你应该这样定义它：

.modal-vue {
  display: none;
}

工作示例：

var vm = new Vue({
  el: "#app",
  props: {},
  data: {
    showDetailModal: false,
  },
  methods: {
    openModal() {
      console.log(this.showDetailModal);
      this.showDetailModal = true;
      console.log(this.showDetailModal);
    }
  },
});
.modal-vue .overlay {
  //display: none;
  text-align: center;
  position: fixed;
  z-index: 9998;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  background-color: rgba(0, 0, 0, .5);
}

.modal-vue {
  display: none;
}

.modal-vue .modal {
  position: relative;
  width: 300px;
  z-index: 9999;
  margin: 0 auto;
  padding: 20px 30px;
  background-color: #fff;
}

.modal-vue .close {
  position: absolute;
  top: 10px;
  right: 10px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>

<div id="app">

  <div @click="openModal()">
    Open Modal
  </div>

  <div class="modal-vue" v-if="showDetailModal" :style="'display: ' + (showDetailModal ? 'block' : 'none')">
    <!-- overlay to help with readability of modal -->
    <div class="overlay" @click="showDetailModal = false"></div>

    <!-- Modal for detail on table cell click event -->
    <div class="modal" v-if="showDetailModal">
      <button class="close" @click="showDetailModal = false">x</button>
      <h3>Testing</h3>
    </div>
  </div>

</div>
