get-safe-value

用一种安全的方式，获取某种特定数据类型的值的函数工具库。

安装

Install with npm

  npm install --save get-safe-value

使用

import { getString, getNumber, getBoolean, getObject, getArray, getFunction, getAny } from 'get-safe-value';
// or
// const { getString, getNumber, getBoolean, getObject, getArray, getFunction, getAny } =  require('get-safe-value');
const obj = {
	name: 'lucas',
	age: 30,
	brother: [
		{ 
			name: 'jack',
			age: 25,
		}
	],
	getName: ()=>{
		return this.name;
	},
}
// getString
console.log(getString(obj, "name")); // 'lucas'
console.log(getString(obj, "age")); // '30'  字符串 数组 和布尔值，都会调用String构造函数转成String类型
console.log(getString(obj, "helloWorld")); // ''
console.log(getString(obj, "brother[0].name")); // 'jack'
console.log(getString(obj, ["name", "brother[0].name"])); // ["lucas", "jack"]

//getNumber
console.log(getNumber(obj, "age")); //30
console.log(getNumber(obj, "name")); //0

//getBoolean
console.log(getBoolean({is: true}, "is")) // true
console.log(getBoolean({is: false}, "is")) // false
console.log(getBoolean({is: false}, "hello")) // false

//getObject
console.log(getObject(obj, "brother[0]")) // { name:'jack', age: 25 }
console.log(getObject(obj, "hello")) // {}

//getArray
console.log(getArray(obj, "brother")) // [{ name:'jack', age: 25 }]
console.log(getArray(obj, "name")) // []

//getFunction
console.log(getFunction(obj, "name")) // function(){}
console.log(getFunction(obj, "getName")) // function getName(){}

//getAny
console.log(getAny(obj, "name")) // 'lucas'
console.log(getAny(obj, "age")) // 30,
console.log(getAny(obj, "hello")) // undefined
