一、普通选择器

<template><view><picker @change="bindPickerChange" :value="index" :range="array" range-key="name"><view style="padding: 20rpx;background-color: white;">{{ array[index].name }}</view></picker></view>
</template>
<script>
export default {data() {return {array: [{ name: '中国' }, { name: '美国' }, { name: '巴西' }, { name: '日本' }],index: 2,};},methods: {bindPickerChange: function(e) {this.index = e.detail.value;}}
};
</script>

二、多列选择器

<template><view><picker mode="multiSelector" @columnchange="bindMultiPickerColumnChange" :value="multiIndex" :range="multiArray"><view style="background-color: white;">{{ multiArray[0][multiIndex[0]] }}，{{ multiArray[1][multiIndex[1]] }}，{{ multiArray[2][multiIndex[2]] }}</view></picker></view>
</template>
<script>
export default {data() {return {multiArray: [['亚洲', '欧洲'], ['中国', '日本'], ['北京', '上海', '广州']],multiIndex: [0, 0, 0]};},methods: {bindMultiPickerColumnChange: function(e) {this.multiIndex[e.detail.column] = e.detail.value;switch (e.detail.column) {case 0: //拖动第1列switch (this.multiIndex[0]) {case 0:this.multiArray[1] = ['中国', '日本'];this.multiArray[2] = ['北京', '上海', '广州'];break;case 1:this.multiArray[1] = ['英国', '法国'];this.multiArray[2] = ['伦敦', '曼彻斯特'];break;}this.multiIndex.splice(1, 1, 0);this.multiIndex.splice(2, 1, 0);break;case 1: //拖动第2列switch (this.multiIndex[0] //判断第一列是什么) {case 0:switch (this.multiIndex[1]) {case 0:this.multiArray[2] = ['北京', '上海', '广州'];break;case 1:this.multiArray[2] = ['东京', '北海道'];break;}break;case 1:switch (this.multiIndex[1]) {case 0:this.multiArray[2] = ['伦敦', '曼彻斯特'];break;case 1:this.multiArray[2] = ['巴黎', '马赛'];break;}break;}this.multiIndex.splice(2, 1, 0);break;}this.$forceUpdate();}}
};
</script>

三、时间选择器

<template><view><picker mode="time" :value="time" :start="minTime" :end=maxTime @change="bindTimeChange"><view style="background-color: white;">{{ time }}</view></picker></view>
</template>
<script>
export default {data() {return {time: '12:01',minTime:'09:01',maxTime:"21:01"};},methods: {bindTimeChange: function(e) {this.time = e.detail.value;}}
};
</script>

四、日期选择器

<template><view><picker mode="date" :value="date" :start="startDate" :end="endDate" @change="bindDateChange"><view style="background-color: #07C160;">{{ date }}</view></picker></view>
</template>
<script>
function getDate(type) {const date = new Date();let year = date.getFullYear();let month = date.getMonth() + 1;let day = date.getDate();if (type === 'start') {year = year - 10;} else if (type === 'end') {year = year + 10;}month = month > 9 ? month : '0' + month;day = day > 9 ? day : '0' + day;return `${year}-${month}-${day}`;
}
export default {data() {return {date: getDate({format: true}),startDate: getDate('start'),endDate: getDate('end'),};},methods: {bindDateChange: function(e) {this.date = e.detail.value;}}
};
</script>
