Faker.js random number between 2 values
提问by K20GH
This one is driving me a little mad, im sure it's simple but it doesn't seem to be documented anywhere.
这个让我有点生气,我相信它很简单,但似乎没有任何地方记录。
Im using https://github.com/marak/Faker.js/and the following to generate my random number:
我使用https://github.com/marak/Faker.js/和以下内容来生成我的随机数:
faker.random.number();
Works great, now if I want to do it between 2 numbers, how would I go about this?
效果很好,现在如果我想在 2 个数字之间进行,我该怎么做?
I tried the following:
我尝试了以下方法:
faker.random.number(10, 50);
however that just gives me numbers from 0 to 10. No idea what the 50 is doing
然而,这只是给了我从 0 到 10 的数字。不知道 50 在做什么
Can anyone give me some directions to this please
任何人都可以给我一些指示吗

You need to give an object to the function:
您需要为该函数提供一个对象:
faker.random.number({
'min': 10,
'max': 50
});
So if you just pass a number, it will set it as the max value. The min value is 0 by default.
因此,如果您只传递一个数字,它会将其设置为最大值。最小值默认为 0。
This is the implementation of the number function :
这是 number 函数的实现:
this.number = function (options) {
if (typeof options === "number") {
options = {
max: options
};
}
options = options || {};
if (typeof options.min === "undefined") {
options.min = 0;
}
if (typeof options.max === "undefined") {
options.max = 99999;
}
if (typeof options.precision === "undefined") {
options.precision = 1;
}
// Make the range inclusive of the max value
var max = options.max;
if (max >= 0) {
max += options.precision;
}
var randomNumber = options.precision * Math.floor(
mersenne.rand(max / options.precision, options.min / options.precision));
return randomNumber;
}

From Fakerjs github
Whole Number faker.random.number(min,max)Random number between 0 and "range".
整数伪造者。random.number(min,max)0 和“范围”之间的随机数。
faker.random.number(100); //returns 92
faker.random.number({min:5, max:10}); //returns 9
Decimal number faker.finance.amount(min,max,decimal places)Random number between "min" and "max" including decimals to X digits.
十进制数伪造者。Finance.amount(min,max,decimal Places)“min”和“max”之间的随机数,包括小数到 X 位。
faker.finance.amount(9000,10000,4); //returns 9948.8363
Boolean faker.random.boolean()
布尔伪造者。random.boolean()
faker.random.boolean(); //returns true
Array Element faker.random.arrayElement(array[])Selects a random element from an array of possible values. This function is useful to create custom lists of possibilities.
数组元素伪造者。random.arrayElement(array[])从可能值的数组中选择一个随机元素。此功能可用于创建自定义可能性列表。
faker.random.arrayElement(["one","two","three","four"]); //returns "two"
var phTyp = faker.random.arrayElement(["cell","work","home"]); //returns "work"
Object Element faker.random.objectElement(object{})Selects a random element from an object, selects the value not the keys. This function is useful to create custom lists of possibilities.
对象元素伪造者。random.objectElement(object{})从对象中选择一个随机元素,选择值而不是键。此功能可用于创建自定义可能性列表。
faker.random.objectElement({one: 1, two: 2, three: 3}); //returns 3

try passing a hash like below
尝试传递如下所示的哈希值
faker.random.number({ min: 10, max: 50})
