JS 对象转数组_jquery把对象转成数组

let obj={name:'xilin',age:23}

let arr=[]

for(var i in obj){

  // console.log(i,obj[i])//name xilin,age 23

  console.log(arr.push(obj[i]))//入栈   1  2

}

console.log(arr)//[ 'xilin', 23 ]

let obj={name:'xilin',age:23}

let t=Object.values(obj);

console.log(t)//[ 'xilin', 23 ]

let obj={name:'xilin',age:23}

let t2=Object.entries(obj)

console.log(t2)//[ [ 'name', 'xilin' ], [ 'age', 23 ] ]

// 数组的偏平化  flat(参数)，flat(2)偏平2层 默认值，flat(Infinity)无穷层  扁平完

console.log(t2.flat())//[ 'name', 'xilin', 'age', 23 ] 

let obj2 = {

  0: 'q',

  1: 'w',

  2: 'e',

  length: 3

} //类数组对象

let arr2 = Array.from(obj2)   //es6

console.log(arr2);  //[ 'q', 'w', 'e' ]

let obj={name:'xilin',age:23}

let obj2 = {

  0: 'q',

  1: 'w',

  2: 'e',

  length: 3

} //类数组对象

console.log(Array.prototype.slice.call(obj)) //[]  

console.log(Array.prototype.slice.call(obj2))//[ 'q', 'w', 'e' ]
