在给定的范围内返回一个随意值。
npm install vvpvvp
npm install --save vvpvvp
let a = vvpvvp([1, 2], 2);
//1.48
let a = vvpvvp([3], 3);
//3.123
let a = vvpvvp([-1, 3], 3);
//-0.123
vvpvvp([start, ], <toFixed = 2>)

觉得挺不错的, 但是这个homepage改一下吧, npm右边上点一下是moment, 大写的尴尬
我直接集成到vue中就是不行
可以支持typescript吗
就是模型定义里面的 key 是 name, 而 服务端返回的数据里面就不按约定叫 name, 他给改成了 username, 而我们事先已经按照约定写了N多的业务逻辑,这时候去改模型定义的 name 显然是不合适的,但如果可以定义一个转义 key, 例如:
export default new Model({
int: Number,
date: {
type: Date,
format: 'YYYY-MM-DD' //此处使用manba日期工具
},
money: {
type: Number,
unit: Model.W
},
name: {
type: String,
jsonKey: ‘username’
}
})
然后可以按照转义 key username 去取值,这样就不需要到各种业务里面去把 name 改为 username 了,只需要在模型定义处定义一下就可以了
不知道我是否说清楚了
const target = [{a: 1}, {a: 2}]
,
How to define target as a Model, then I can use target.parse() to parse
"babel-cli": "^6.26.0",
"babel-preset-es2015": "^6.24.1",
"babel-core": "^6.26.0",
"chai": "^4.1.2",
"manba": "^1.0.1"
const __Model = require('../src/model');
let _dataM = new __Model({
a: Number,
b: String,
c: Date,
d: Boolean,
e: Array,
f: Object
});
let _r = _dataM.parse({
a: 'sdf12asd',
b: 12
});
parse 数据可以是这样的 吗
{ c: new Date, d: false, e: [], f: {}, a: 0, b: '12' }

模型定义:
let User = new Model({
id: 0,
follower_num: 0,
following_num: 0,
is_following: false,
type: String,
real_name: String,
avatar_url: String,
title: String,
introduction: String,
})
我发现把 type: String
改成 type1: String
就没问题了,问题可能出现在对属性名的判断上?
另外,请问能否支持Boolean类型的定义?默认false。
const banners = new Model({
imgUrls: {
type: [''],
default: ['http://via.placeholder.com/750x306'],
},
});
这样用的话会返回一个空数组
import Model from 'js-model'
const modelTest = new Model({
a: {
type: Array,
defalut: []
}
})
console.log(modelTest.parse({}))
返回结果
{
a: {
type: null,
defalut: Array(0)
}
}
正常不应该是返回
{
a: []
}
吗?
