工具函数库-数据类型判断

数据类型判断

1. 是否字符串

export const isString = (o) => {
    return Object.prototype.toString.call(o).slice(8, -1) === 'String'
}

2. 是否数字

export const isNumber = (o) => {
    return Object.prototype.toString.call(o).slice(8, -1) === 'Number'
}

3. 是否boolean

export const isBoolean = (o) => {
    return Object.prototype.toString.call(o).slice(8, -1) === 'Boolean'
}

4. 是否函数

export const isFunction = (o) => {
    return Object.prototype.toString.call(o).slice(8, -1) === 'Function'
}

5. 是否为null

export const isNull = (o) => {
    return Object.prototype.toString.call(o).slice(8, -1) === 'Null'
}

6. 是否undefined

export const isUndefined = (o) => {
    return Object.prototype.toString.call(o).slice(8, -1) === 'Undefined'
}

7. 是否对象

export const isObj = (o) => {
    return Object.prototype.toString.call(o).slice(8, -1) === 'Object'
}

8. 是否数组

export const isArray = (o) => {
    return Object.prototype.toString.call(o).slice(8, -1) === 'Array'
}

9. 是否时间

export const isDate = (o) => {
    return Object.prototype.toString.call(o).slice(8, -1) === 'Date'
}

10. 是否正则

export const isRegExp = (o) => {
    return Object.prototype.toString.call(o).slice(8, -1) === 'RegExp'
}

11. 是否错误对象

export const isError = (o) => {
    return Object.prototype.toString.call(o).slice(8, -1) === 'Error'
}

12. 是否Symbol函数

export const isSymbol = (o) => {
    return Object.prototype.toString.call(o).slice(8, -1) === 'Symbol'
}

13. 是否Promise对象

export const isPromise = (o) => {
    return Object.prototype.toString.call(o).slice(8, -1) === 'Promise'
}

14. 是否Set对象

export const isSet = (o) => {
    return Object.prototype.toString.call(o).slice(8, -1) === 'Set'
}
