Javascript 如何重命名对象键&；将对象值从字符串更改为数字

好的，伙计们

我正在处理来自

React

的

第三方库，希望操纵状态，以便以后可以将这种新的代码格式推送到新的

对象中

当我使用这个库以一个值为目标时，无论我何时选择，我的状态都是这样的字符串-例如，如果我选择20:30，
this.state.time
等于
“20:30”

我想将这个
字符串
处理成如下对象：

从
“20:30”
到
时间：{hour:20，minutes:30}
///小时和分钟现在都是数字

我的完整代码如下：

import React from "react";
import TimePicker from "react-time-picker";
import './Clock.css'

class Clock extends React.Component {

    state = {
        time: '0:00',
        pushTime: [],
        value: ''
    };

    onChangeTimePickerHandler = time => {
        this.setState({time});
        let currentTime = this.state.time;
        this.props.CallbackRenderTime(currentTime)
    };

    //I am using TimePicker library for React and want to manipulate the income from the chosen time
    pushNewTimeHandler = () => {
        let time = [...this.state.time] ;// ["1", "0", ":", "0", "0"]
        time.splice(2, 1);
        let timeToOneString = time.join().replace(/,/g, "");
         let prepareStringForNewObject = (value, index) => {
             let array = value.substring(0,index) + ',' + value.substring(index);
             return array.split(',')
         };
        let newObj = {...prepareStringForNewObject(timeToOneString,2)};
        console.log(newObj); // {0: "10", 1: "00"}
    };

    render() {

        return (
            <div>
                <TimePicker
                    onChange={this.onChangeTimePickerHandler}
                    value={this.state.time}/>
                    <button onClick={this.pushNewTimeHandler}>Push the Array of Time</button>
                    <p>{this.state.time}</p>
            </div>


        )
    }
}

export default Clock

因此，在我丑陋的解决方案
pushNewTimeHandler
中，我仍然需要将对象键重命名为
hour
和
minutes
，还需要将小时和分钟的字符串值转换为数字。
我将时间字符串拆分为
：
，创建一个字符串数组，然后将每个字符串映射到一个数字，并将结构分解为
=
左侧的
小时和
分钟。然后，您可以创建
小时
和
分钟
的对象：


const str='20:30'；
const[hour，minutes]=str.split（“：”）.map（Number）；
const obj={小时，分钟}；
控制台日志（obj）
 //I am using TimePicker library for React and want to manipulate the income from the chosen time
    manipulateTimeHandler = () => {
        //this.state.time is "10:00"
        let time = [...this.state.time] ;// now it looks like this: ["1", "0", ":", "0", "0"]
        time.splice(2, 1);
        let timeToOneString = time.join().replace(/,/g, "");
         let prepareStringForNewObject = (value, index) => {
             let array = value.substring(0,index) + ',' + value.substring(index);
             return array.split(',')
         };
        let newObj = {...prepareStringForNewObject(timeToOneString,2)};
        console.log(newObj); //finally it became the object, but the object values are still 
                            //strings and the object keys still need to be changed into "hour" 
                           //and "minutes" {0: "10", 1: "00"}
    };
