非空判断
作者：互联网
const isEmpty = (obj: any) => {
let isEmpty = false
if (obj === undefined || obj === null || obj === '') {
isEmpty = true
} else if (Array.isArray(obj) && obj.length === 0) {
isEmpty = true
} else if (obj.constructor === Object && Object.keys(obj).length === 0) {
isEmpty = true
}
return isEmpty
}
