English Docs | 中文文档

🎨 Features

• A mobile select component with vanilla js, do not dependent on any library
• Can be passed to an ordinary array or json array
• According to the length of the parameters passed, automatically render the corresponding number of columns, support for individual to multiple options
• Automatic identification is cascading
• Provide a custom callback function 'onChange()'
• After each gesture sliding, it also provides a callback function 'onTransitionEnd()'

📗 Quick Start

①Ordinary array format - Non-cascade

<div id="day"></div>

<script type="text/javascript">
  let mobileSelect1 = new MobileSelect({
    trigger: document.querySelector("#day"),
    title: "单项选择",
    wheels: [
      { data: ["周日", "周一", "周二", "周三", "周四", "周五", "周六"] },
    ],
    initValue: "周二", // Initialize value
  });
</script>

②Json format - Non-cascade

<div id="area"></div>

<script type="text/javascript">
  let mobileSelect2 = new MobileSelect({
    trigger: "#area",
    title: "地区选择",
    wheels: [
      {
        data: [
          { id: "1", value: "附近" },
          { id: "2", value: "上城区" },
          { id: "3", value: "下城区" },
          { id: "4", value: "江干区" },
          { id: "5", value: "拱墅区" },
          { id: "6", value: "西湖区" },
        ],
      },
      {
        data: [
          { id: "1", value: "1000米" },
          { id: "2", value: "2000米" },
          { id: "3", value: "3000米" },
          { id: "4", value: "5000米" },
          { id: "5", value: "10000米" },
        ],
      },
    ],
    onChange: function (data, indexArr, msInstance) {
      console.log(data);
    },
  });
</script>

Example：

③Json format - Cascade

<div id="area2"></div>

<script type="text/javascript">
  let mobileSelect3 = new MobileSelect({
    trigger: "#area2",
    title: "地区选择-联动",
    wheels: [
      {
        data: [
          {
            id: "1",
            value: "附近",
            childs: [
              { id: "1", value: "1000米" },
              { id: "2", value: "2000米" },
              { id: "3", value: "3000米" },
              { id: "4", value: "5000米" },
              { id: "5", value: "10000米" },
            ],
          },
          { id: "2", value: "上城区" },
          { id: "3", value: "下城区" },
          { id: "4", value: "江干区" },

          { id: "6", value: "西湖区" },
        ],
      },
    ],
    initValue: "附近 2000米", // Initialize value
    onChange: function(data, indexArr, msInstance) {
      console.log(data); // Returns the selected value
    },
  });
</script>

④How to use in React or Vue

Use in React demo:

import { useState, useRef, useEffect } from "react";
import MobileSelect from "mobile-select";

export default function MsComponent(props) {
  const tirggerRef = useRef(null);
  const [selectedVal, setSelectedVal] = useState('');
  let msInstance = null;
  useEffect(() => {
    if(!msInstance){
      msInstance = new MobileSelect({
          wheels: [
            { data: ["周日", "周一", "周二", "周三", "周四", "周五", "周六"] },
          ],
          trigger: tirggerRef.current,
          triggerDisplayValue: false, // If you don't want to overwrite the HTML inside the trigger, you need to set this to false
          onChange: (data) => {
            setSelectedVal(JSON.stringify(data));
          },
        });
    }
    return () => {
      msInstance?.destroy();  // Destroying instance
    };
  }, []);
  return (
    <div>
      <div className="ms-default-trigger" ref={ tirggerRef }>
        <div className="your-classname">{ selectedVal || 'please select...' }</div>
      </div>
    </div>
  );
}

Use in Vue demo:

<template>
  <div>
    <div ref="tirggerRef">
      <div class="your-classname">{{ selectedVal || "please select..." }}</div>
    </div>
  </div>
</template>

<script>
  import MobileSelect from "mobile-select";
  export default {
    name: "mobile-select",
    data: () => ({
      msInstance: null,
      selectedVal: "",
    }),
    mounted() {
      this.msInstance = new MobileSelect({
        trigger: this.$refs.tirggerRef,
        wheels: [
          { data: ["周日", "周一", "周二", "周三", "周四", "周五", "周六"] },
        ],
        triggerDisplayValue: false, // If you don't want to overwrite the HTML inside the trigger, you need to set this to false
        onChange: (data) => {
          this.selectedVal = JSON.stringify(data);
        },
      });
    },
    unmounted() {
      this.msInstance.destroy(); // Destroying instance
    },
  };
</script>

⑤Json format - Data field mapping

<div id="trigger6"></div>

<script type="text/javascript">
  // If your data field is named id, title, children
  // does not match the id, value, childs field name of mobileSelect
  // You can use the keyMap property for field name mapping
  let mobileSelect6 = new MobileSelect({
    trigger: "#trigger6",
    title: "keyMap",
    wheels: [
      {
        data: [
          {
            id: "1",
            title: "A",
            children: [
              { id: "A1", title: "A-a" },
              { id: "A2", title: "A-b" },
              { id: "A3", title: "A-c" },
            ],
          },
          {
            id: "1",
            title: "B",
            children: [
              { id: "B1", title: "B-a" },
              { id: "B2", title: "B-b" },
              { id: "B3", title: "B-c" },
            ],
          },
        ],
      },
    ],
    keyMap: {
      id: "id",
      value: "title",
      childs: "children",
    },
    onChange: function(data, indexArr, msInstance) {
      console.log(data);
    },
  });
</script>

Tips: The meaning of the parameters returned in the callback function is as follows

• indexArr is the currently selected index array, such as[0,0,1]
• data is the currently selected json array, such as[{id:'1',value:'hello'},{id:'2',value:'world'}]

Tips: The function parameters need to be passed as follows

• SliderIndex represents the index of the wheel to be modified
• PosIndex represents the location index

①Demo of use the function ：

<div id="day"></div>

<script>
let mySelect = new MobileSelect({
    trigger: '#day',
    wheels: [
        {data:['周日','周一','周二','周三','周四','周五','周六']},
        {data:['08:00','09:00','10:00','11:00','12:00','13:00','14:00']}
    ],
    initValue: "周一 09:00",
    colWidth: [1, 2] // initialize the col width setting, The number represents the width ratio of each column
});

//----------------------------------------------
//After the basic instantiated, use the functions

/** Set the title of the component */
mySelect.setTitle('啦啦啦(๑•̀ㅁ•́ฅ)');

/** Update the 0th wheel of the data,the data from the Chinese week to the English week */
mySelect.updateWheel(0,['sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday']);

/** Reposition the position of the first wheel and change the 0th data of the first wheel to the current selection. */
mySelect.locatePosition(1,0);

/** Destruction of the component */
mySelect.destroy();
</script>

Project demo：

Use the onTransitionEnd (), onChange (), updateWheel (), locatePosition () functions to do the following:

• choose the date of the day, not more than today has been too.
• Select the time to take the car, the car must not exceed the time to take the car (including the date and time).
