2.pickerTime.wxml内容
<!--component/pickerTime/pickerTime.wxml-->
<view>
<picker disabled="{{disabled}}" mode="multiSelector" bindchange="pickerChange" bindcolumnchange="pickerColumnChange" bindcancel ="pickerCancel" value="{{pickerIndex}}" range="{{pickerArray}}" range-key="{{'name'}}">
<view>
{{placeholder}}
</view>
</picker>
</view>
在页面中使用
1,demo.json中引入组件
{
"navigationBarTitleText": "demo",
"usingComponents": {
"pickerTime": "/components/pickerTime/pickerTime"
}
}
2,页面中使用 wxml
<pickerTime placeholder="{{placeholder}}" date="{{date}}" bind:onPickerChange="onPickerChange"
startDate="{{startDate}}" endDate="{{endDate}}">
</pickerTime>
3.demo.js
data:{
date: '2019-01-01 13:37',
startDate: '2019-01-01 12:37',
endDate: '2029-03-12 12:38',
placeholder: '请选择时间'
},
onPickerChange: function (e) {
this.setData({
date: e.detail.dateString //选中的数据
})
},
toDouble: function (num) {
if (num >= 10) {//大于10
return num;
} else {//0-9
return '0' + num
}
},
getToday: function () {
let date = new Date();
let year = date.getFullYear();
let month = date.getMonth() + 1;
let day = date.getDate();
return year + '-' + this.toDouble(month) + '-' + this.toDouble(day)
},
//监听页面加载
onLoad: function (options) {
let dayTime= this.getToday();
let dayHour = "18:00";
let endedTime1 = dayTime + " " + dayHour;
this.setData({
date: endedTime1
})
},
