i-picker v1.1.0

i-picker 选择器

A powerful mobile picker component for Vue. Supports datetime or custom select option

使用指南

import iPicker from 'i-picker';

Vue.use(iPicker);

普通 Picker 代码演示

基础用法

通过 values 来设置默认值或改变对应值，注意不要设置列表数据中不存在的value值 非datetime需要设置 columns 列数据

<button @click="show = true">show</button>
<i-picker v-model="show" :value="values" :columns="columns" @change="onChange" />

export default {
  data() {
    return {
      values: [],
      columns: ['杭州', '宁波', '温州', '嘉兴', '湖州']
    };
  },
  methods: {
    onChange (picker, text, index, disabled) {
      console.log(`当前值：${text}, 当前value：${this.values}, 当前索引：${index}, 当前数据disabled状态：${disabled}`);
    }
  }
};

禁用选项

选项可以为对象结构，通过设置 disabled 来禁用该选项

如果设置的values中的数据是 disabled 状态，则默认为下一个 disabled 不为true的数据

如果该列所有的选项都是 disabled 的状态，默认返回第一个，可以通过 change 事件最后一个返回参数 disabled 来判断数据状态

<i-picker v-model="show" :value="values" :columns="columns" @confirm="onConfirm" />

let yearTotal = []
for (var i = 2000; i <= 2030; i++) {
  yearTotal.push({
    name: i + '年',
    value: i,
    disabled: i % 5 === 0
  })
}

export default {
  data() {
    return {
      values: [],
      columns: yearTotal
    };
  },
  methods: {
    onConfirm (text, value, index, disabled) {
      this.values = value
    }
  }
};

展示顶部栏

<i-picker 
  v-model="show"
  :value="values"
  :columns="columns"
  @change="onChange"
  @cancel="onCancel"
  @confirm="onConfirm"
  :visibleItemCount="5"
  toolbar
  title="iPicker"/>

export default {
  data() {
    return {
      values: [2],
      columns: [
        {name: '杭州', disabled: true},
        {name: '宁波'},
        {name: '温州', disabled: true},
        {name: '嘉兴'},
        {name: '湖州'}
      ]
    }
  },
  methods: {
    onConfirm (text, value, index, disabled) {
      this.values = value
      console.log(`当前值：${text}, 当前索引：${index}`);
    },
    onCancel() {
      console.log('取消');
    }
  }
};

多列异步动态联动

keys 用于设置多列列表的数据，一个 keys 对应一个列表的数据

<i-picker
  v-model="show"
  :value="values"
  :columns="columns"
  @change="onChange"
  @cancel="onCancel"
  @confirm="onConfirm"
  toolbar
  title="iPicker"/>

export default {
  data() {
    return {
      values: [],
      columns: [
        {keys: ['浙江', '河北']},
        {keys: [{name: '杭州'}, {name: '宁波', disabled: true}, {name: '温州'}]}
      ]
    };
  },
  methods: {
    onChange (picker, text, value, index, disabled) {
      switch(text[0]) {
        case '浙江':
          picker.setColumnKeys(1, [{name: '杭州'}, {name: '宁波', disabled: true}, {name: '温州'}]);
          break;
        case '河北':
          picker.setColumnKeys(1, [
            {name:'石家庄市', value: 'shijiazhuang'},
            {name:'唐山市', value: 'tangshan'},
            {name:'秦皇岛市', value: 'qinhuangdao'},
            {name:'邯郸市', value: 'handan'},
            {name:'邢台市', value: 'xingtai'},
            {name:'保定市', value: 'baoding'}
          ]);
          break;
        default:
          break;
      }
    },
    onConfirm (text, value, index, disabled) {
      this.values = value
    },
    onCancel () {
      console.log('cancle')
    }
  }
};

多列父子联动

<i-picker 
  v-model="show"
  :value="values"
  :columns="columns"
  @cancel="onCancel"
  @confirm="onConfirm"
  toolbar
  title="iPicker"/>

export default {

    return {
      values: ['cn004', 'yuncheng'],
      columns: [

列表数据格式

单列数据格式

// data
['杭州', '宁波', '温州']

// 或者使用 name => value 的形式，不设置value的话默认是数组索引值
[
  { name: '杭州', value: 'city01', disabled: true },
  { name: '宁波', value: 'city02'  },
  { name: '温州', value: 'city03', disabled: true  },
]

多列数据格式

keys 数据对应一个列表数据

// ajax异步动态数据
[
  { 
    keys: ['浙江', '天津', '河北', '山西'],
    className: 'column1'
  },
  { 
    keys: [{ name: '杭州' }, { name: '宁波', disabled: true  }, { name: '温州' }]  
  }
]

// 或者父子联动数据

加载状态

当 Picker 数据是通过异步获取时，可以通过 loading 属性显示加载提示

<i-picker v-model="show" :value="values" :columns="columns" :loading="loading" />

自定义展示选项

<i-picker 
  v-model="show"
  :value="values"
  :columns="columns"
  @change="onChange"
  @cancel="onCancel"
  @confirm="onConfirm"
  :visibleItemCount="5"
  toolbar
  title="iPicker"/>

import icon from './assets/tui.png'

export default {
  data() {
    return {
      values: [1],
      columns: [
        {name: '宁波'},
        {name: `<img src="${icon}" class="y-custom-icon">杭州`},
        {name: '温州'},
        {name: '嘉兴'},
        {name: '湖州'}
      ]
    }
  },
  methods: {
    onConfirm (text, value, index, disabled) {
      this.values = value
      console.log(`当前值：${text}, 当前索引：${index}`);
    },
    onCancel() {
      console.log('取消');
    }
  }
};

<style>
.y-custom-icon {
  width: 22px;
  height: 22px;
  margin: 0 3px 0 0;
  vertical-align: text-bottom;
}
</style>

datetime Picker 代码演示

基础用法

需要设置 type 类型

<i-picker
  v-model="show"
  :value="currentDate"
  format="YYYY-MM-DD HH:mm:ss"
  type="datetime"
  :min-date="minDate"
  :max-date="maxDate"
  @change="onChange"
  toolbar
  @cancel="onCancel"
  @confirm="onConfirm"
  title="iPicker"/>

export default {
  data() {
    return {
      currentDate: new Date(2018, 0, 1),
      minDate: new Date(2018, 0, 1),
      maxDate: new Date(2019, 10, 1)
    };
  },
  methods: {
    onConfirm (text, value, index, disabled) {
      this.currentDate = value
      console.log(`当前值：${text.join(',')}, 当前value：${value.join(',')}, 当前索引：${index.join(',')}`);
    }
  }
};

选择年月

通过传入 formatter 函数对选项文字进行处理

<i-picker
        v-model="show"
        :value="currentDate"
        format="YYYY-MM"
        type="year-month"
        :min-date="minDate"
        :max-date="maxDate"
        :formatter="formatter"
        toolbar
        @cancel="onCancel"
        @confirm="onConfirm"
        title="iPicker"/>

export default {
  data() {
    return {
      currentDate: new Date(2018, 8, 1),
      minDate: new Date(2018, 0, 1),
      maxDate: new Date(2019, 10, 1)
    }
  },
  methods: {
    formatter (type, value) {
      if (type === 'year') {
        return `${value}年`
      } else if (type === 'month') {
        return `${value}月`
      }
      return value
    },
    onConfirm (text, value, index) {
      this.currentDate = value
      console.log(`当前值：${text.join(',')}, 当前value：${value.join(',')}, 当前索引：${index.join(',')}`);
    }
  }
};

选择时间

<i-picker
  v-model="show"
  :value="currentTime"
  type="time"
  :min-hour="minHour"
  :max-hour="maxHour"
  @change="onChange"
  toolbar
  @cancel="onCancel"
  @confirm="onConfirm"
  title="iPicker"/>

export default {
  data() {
    return {
      currentTime: '12:30',
      minHour: 10,
      maxHour: 30
    }
  },
  methods: {
    onConfirm (text, value, index) {
      this.currentDate = value
      console.log(`当前值：${text.join(',')}, 当前value：${value.join(',')}, 当前索引：${index.join(',')}`);
    }
  }
};

Columns 数据结构

当传入多列数据时，columns为一个对象数组，数组中的每一个对象配置每一列，每一列有以下key

方法

通过 ref 可以获取到 picker 实例并调用实例方法
