好的,以下是一个简单的实现点击按钮弹出弹窗的示例:
```
<template>
<div>
<button @click="showModal = true">点击打开弹窗</button>
<div class="modal" v-if="showModal">
<div class="modal-mask"></div>
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title">弹窗标题</h4>
<button type="button" class="close" @click="closeModal">
<span>×</span>
</button>
</div>
<div class="modal-body">弹窗内容</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" @click="closeModal">关闭</button>
</div>
</div>
</div>
</div>
</div>
</template>
<script>
export default {
data() {
return {
showModal: false
};
},
methods: {
closeModal() {
this.showModal = false;
}
}
};
</script>
<style>
.modal {
position: fixed;
top: 0;
left: 0;
right: 0;
bottom: 0;
display: flex;
align-items: center;
justify-content: center;
z-index: 9999;
}
.modal-mask {
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
background-color: rgba(0, 0, 0, 0.5);
}
.modal-dialog {
position: relative;
width: 500px;
max-width: 100%;
margin: 0 auto;
}
.modal-content {
position: relative;
background-color: #fff;
border-radius: 4px;
box-shadow: 0 0 10px rgba(0, 0, 0, 0.3);
}
.modal-header {
padding: 10px;
border-bottom: 1px solid #eee;
display: flex;
align-items: center;
justify-content: space-between;
}
.modal-title {
margin: 0;
font-size: 18px;
}
.modal-body {
padding: 10px;
}
.modal-footer {
padding: 10px;
border-top: 1px solid #eee;
display: flex;
justify-content: flex-end;
}
.btn {
display: inline-block;
padding: 6px 12px;
margin-bottom: 0;
font-size: 14px;
font-weight: 400;
line-height: 1.42857143;
text-align: center;
white-space: nowrap;
vertical-align: middle;
cursor: pointer;
border: 1px solid transparent;
border-radius: 4px;
user-select: none;
}
.btn-secondary {
color: #fff;
background-color: #333;
border-color: #333;
}
.btn-secondary:hover {
color: #fff;
background-color: #292929;
border-color: #292929;
}
</style>
```
使用方法:
1. 在需要使用弹窗的组件中引入该组件:
```
<template>
<div>
<button @click="showModal = true">点击打开弹窗</button>
<Modal v-if="showModal" @close="closeModal">
<div slot="header">弹窗标题</div>
<div slot="body">弹窗内容</div>
<div slot="footer">
<button class="btn btn-secondary" @click="closeModal">关闭</button>
</div>
</Modal>
</div>
</template>
<script>
import Modal from './Modal.vue';
export default {
components: {
Modal
},
data() {
return {
showModal: false
};
},
methods: {
closeModal() {
this.showModal = false;
}
}
};
</script>
```
2. 在需要使用弹窗的组件中定义一个布尔类型的变量showModal,用于控制弹窗的显示和隐藏。
3. 在需要使用弹窗的组件中定义一个方法closeModal,用于关闭弹窗并将showModal变量设置为false。
4. 在需要使用弹窗的组件中使用Modal组件,并使用slot分发header、body和footer三个插槽,用于自定义弹窗的标题、内容和底部按钮。
