.js

Component({
  /**
   * 组件的属性列表
   */
  properties: {
    // 是否显示
    isShow: {
      type: Boolean,
    },
    // 弹框内容
    content: {
      type: String,
      value: ''
    },
    // 是否显示取消按钮
    showCancel: {
      type: Boolean,
      value: true
    },
    // 确认按钮文本
    confirmText: {
      type: String,
      value: '确认'
    },
  },

  /**
   * 组件的初始数据
   */
  data: {

  },
  /**
   * 组件的方法列表
   */
  methods: {
    close: function () {
      this.setData({
        isShow: false
      });
    },
    Success: function (e) {
      this.triggerEvent('success', '确认')
      this.close();
    },
    Cancel: function (e) {
      this.triggerEvent('sancel', '取消')
      this.close();
    },
  }
})

如何使用

1，在需要的page的json文件引用

{
  "usingComponents": {
    "bullet-box": "/common/component/bulletBox/bulletBox"
  }
}

2在wxml中添加

 <bullet-box isShow="{{isBulletBoxShow}}" content='确认撤销送货单？' bind:success='onSuccess'></bullet-box>

3在js中点击显示和确认函数

data{
    isBulletBoxShow:false
},
 // 点击撤销/弹框
  cancelDelivery:function(e){
    this.setData({
      isBulletBoxShow: true,
    })
  },
  // 弹框确认
  onSuccess:function(e) {
   
  },
