uniapp 实现复制功能（h5）

实现效果

1、安装 vue-clipboard2 插件（非h5也可以调用官方API实现）

npm install --save vue-clipboard2

2、在 main.js 中引入并挂载

// 复制
import VueClipboard from 'vue-clipboard2'
Vue.use(VueClipboard)

3、组件中调用

3.1 在 data 中定义数据

data() {
		return {
			value: "7879" //要复制的数据
		}
	},

3.2 在页面上绑定 data 中的数据

//value就是data中的value;this.value就是拿到data中value的值; @tap="copy" 点击事件
<text :value="value">{{this.value}}</text>
<text @tap="copy">复制</text>

3.3 methods 中触发点击事件

methods: {
	// 复制文本
	copy() {
		this.$copyText(this.value).then(
			res => {
				uni.showToast({
					title: '复制成功',
					icon: 'none'
				})
			}
		)
	},
