select-text

可选文本组件。该组件有两种使用模式：长按出现选区，与浏览器默认效果一致；长按出现复制按钮，点击复制拷贝全部内容至剪贴板，常见于聊天对话框等场景。

需注意的时，为实现点击其它区域隐藏复制按钮，开发者可在页面最外层监听 tap 事件，并将 evt 对象赋值给 on-document-tap。

<view bind:tap="handleTap">
  <view class="demo-block">
    <block wx:for="{{arr}}" wx:key="placement">
      <view class="list-item">
        <mp-select-text 
          show-copy-btn 
          placement="{{item.placement}}" 
          value="{{item.value}}" 
          data-id="{{index}}" 
          bindcopy="onCopy"
          on-document-tap="{{evt}}"
        >
        </mp-select-text>
      </view>
    </block>
    <view class="list-item">
      <mp-select-text value="默认的长按效果与浏览器一致"></mp-select-text>
    </view>
  </view>
</view>

Page({
  data: {
    arr: [{
      value: "长按，上侧复制",
      placement: "top"
    }, {
      value: "长按，右侧复制",
      placement: "right"
    }, {
      value: "长按，左侧复制",
      placement: "left"
    }, {
      value: "长按，下侧复制",
      placement: "bottom"
    }]
  },

  onLoad() {

  },

  onCopy(e) {
    console.log("onCopy", e)
  },
  
  handleTouchStart(e) {
    console.log("@@ touchstart", e)
  },

  handleTap(e) {
    console.log("@@ tap", e)
    this.setData({
      evt: e
    })
  }

})
