微信小程序popup组件

git地址：git@github.com:javanf/wx-components.git

注意: popup 组件语法使用小程序，copy需做调整

<br/>

popup主要用来显示了一个弹出式窗口，其中列出了可用的用户管理属性

组件功能实现介绍

wxml实现部分

isShowPop用来控制组件的显示和隐藏

needTitle和title分别是两种title的样式（后面看截图）

<view class="popup-warpper" wx:if="{{isShowPop}}" bingdtap="">
<view class="wrapper">
<view class='title' wx:if="{{needTitle}}">
  <view class='cancel' catchtap="cancel">取消</view>
  <view class='confirm' catchtap="confirm">确定</view>
</view>
<view class='title pop-title' wx:elif="{{title}}">{{title}}</view>
<slot name="after"></slot>
</view>
</view>

js实现部分

详细请看下方注释

Component({
properties: {
title: { // 属性名（组件title）
  type: String,// 类型（必填），目前接受的类型包括：String, Number, Boolean, Object, Array, null（表示任意类型）
  value: 'pop选择', // 属性初始值（可选），如果未指定则会根据类型选择一个
},
needTitle: { // 组件另外一种title样式
  type: Boolean,
  value: false
},
isShowPop: { // 是否显示组件
  type: Boolean,
  value: false
}
},
data: {
},
options: {
multipleSlots: true // 在组件定义时的选项中启用多slot支持
},
methods: {
/**
 * 取消事件（调用父组件方法）
 */
cancel() {
  this.triggerEvent('cancel')
},
/**
 * 确定事件（调用父组件方法）
 */
confirm() {
  this.triggerEvent('confirm')
}
}
})

css实现部分

只写了组件的公共样式部分，slot内容写到具体页面了


.popup-warpper {
width: 100%;
height: 100%;
position: fixed;
left: 0;
bottom: 0;
background: rgba(0,0,0,0.1);
z-index: 999;
}
.popup-warpper .wrapper {
position: absolute;
left: 0;
bottom: 0;
max-height: 818rpx;
width: 100%;
background: #fff;
overflow-y: auto;
}
.popup-warpper .wrapper .title {
height: 110rpx;
line-height: 110rpx;
background: rgba(59,79,98,0.1);
display: flex;
padding: 0 30rpx;
color: #0cc071;
font-size: 34rpx;
}
.popup-warpper .wrapper .title.pop-title {
color: #9da4b5;
font-size: 30rpx;
text-align: center;
display: block;
}
.popup-warpper .wrapper .title .cancel {
flex: 1;
}
.popup-warpper .wrapper .title .confirm {
flex: 1;
text-align: right;
}

## 组件调用实现介绍

### wxml实现部分
* popup组件引入后调用
* isShowPop是传入子组件的属性，控制是否显示
* bindcancel、bindconfirm是传入子组件的方法，用this.triggerEvent('xxx')等方法调用，pCancel、pConfirm是this.triggerEvent('xxx')调用的执行的具体方法
* slot对应组件 slot name="after" 
```HTML
<view>
  <button bindtap="showPop">显示pop组件</button>
  <view class="sitem">已选择item: 
    <text>{{sitem.name}}</text>
  </view>
</view>
<popup isShowPop="{{isShowPop}}" bindcancel="pCancel" bindconfirm="pConfirm">
  <view slot="after">
    <view class='select-ul'>
      <view catchtap='selectLi' data-item="{{item}}" class='li {{item.id==sitem.id?"active":""}}' wx:for="{{selectList}}" item="item" wx:key="key">{{item.name}}
        <em wx:if="{{item.id==sitem.id}}" class='iconfont icon-success'></em>
      </view>
    </view>
  </view>
</popup>

js实现部分

详细请看下方注释

var plugin = requirePlugin("myPlugin")
Page({
data: {
isShowPop: false, // 控制组件是否显示
sitem: '', // 已经选择的属性
selectList: [{ // 供选择的list
  id: 1,
  name: '余票不足'
}, {
  id: 2,
  name: '陪同领导或客户'
}, {
  id: 3,
  name: '起飞或到达时间不合适'
}, {
  id: 4,
  name: '改签或退票因素'
}]
},
onLoad: function() {
plugin.getData();
// 初始化默认选择第一个
let sitem = this.data.selectList[0];
this.setData({
  sitem: sitem
});
this.sitem = sitem;
},
/**
* 选择属性
* @param {} event 
*/
selectLi(event) {
// 获取选择的属性
let item = event.currentTarget.dataset.item;
this.setData({
  sitem: item
});
// 选择完关闭pop，也可以通过`确定`按钮关闭，如没有needTitle就自动关闭
this.setData({
  isShowPop: false
});
this.sitem = item;
},
pCancel() {
console.log('取消pop回调');
this.setData({
  isShowPop: false
});
},
pConfirm() {
console.log('确定pop回调');
console.log(this.sitem);
this.setData({
  isShowPop: false
});
},
/**
* 显示pop事件
*/
showPop() {
this.setData({
  isShowPop: true
});
}
})

css实现部分

这里引入了Iconfont-阿里巴巴矢量图标库（具体运用请待下回讲解）

@font-face {font-family: "iconfont";
