使用 javascript 生成具有特定时间范围的随机模拟数据

Question

我想使用以下结构生成模拟数据。

条件

开始时间和结束时间间隔应为 30 分钟或 1 小时。

同一天2-3次模拟，时间间隔不同

[{
Id: 1,
Subject: 'Bob',
StartTime: new Date(2020, 6, 11, 9, 30),
EndTime: new Date(2020, 6, 11, 11, 0),
CategoryColor: '#1aaa55'
}]

下面是我为生成模拟数据而编写的代码，

但我不确定如何生成数据逻辑。请帮忙

function random() {
for (let index = 0; index <= 100; index++) {
let x = {
Id: getRandomInt(1, 1000),
Subject: generateName(),
StartTime: new Date(2020, 6, 11, 9, 30),
EndTime: new Date(2020, 6, 11, 11, 0),
CategoryColor: getRandomColor()
}
data.push(x);
}
}

Answer 1

您可以将其用于随机名称生成器。 对于随机数生成器，您可以将Math.random()(始终返回 0-1 之间的数字(与Math.floor()结合使用。例如：

Math.floor(Math.random() * 101);  // returns a random integer from 0 to 100

如果我包括间隔，它应该看起来像这样：

let generated_data = []; // this will be the final data
let colors = ["Blue", "Red", "Green"]; // define all the colors you need

function getRandomInt(min, max) { // generate random number
return Math.floor(Math.random() * (max - min)) + min;
}
function capFirst(string) { // make the first letter capital letter
return string.charAt(0).toUpperCase() + string.slice(1);
}

function generateName(){ //generates random Name
var name1 = ["abandoned","able","absolute","adorable"]; // you can add more elements in this list, if you want a wider choice
var name2 = ["people","history","way","art","world"]; // you can add more elements in this list, if you want a wider choice
var name = capFirst(name1[getRandomInt(0, name1.length)]) + ' ' + capFirst(name2[getRandomInt(0, name2.length + 1)]);
return name;
}

function randomDate(date1, date2){ // generates random date
var date1 = date1 || '01-01-1970'
var date2 = date2 || new Date().toLocaleDateString()
date1 = new Date(date1).getTime()
date2 = new Date(date2).getTime()
if( date1>date2){
return new Date(getRandomInt(date2,date1)).toLocaleDateString()   
} else{
return new Date(getRandomInt(date1, date2)).toLocaleDateString()  
}
}
function generateRandomObject() { // adds a random object in the objects list
let obj = {
Id: getRandomInt(1, 1000),
Subject: generateName(),
StartTime: randomDate('01/01/2000', '01/01/2020'),
EndTime: randomDate('01/01/2000', '01/01/2020'),
CategoryColor: colors[getRandomInt(0, colors.length)]
}
generated_data.push(obj);
}

setInterval(generateRandomObject, 30 * 60 * 1000); // sets an interval of 30 mins in which the function  will be executed
