将对象转化为数组

将对象转化为数组

• 方法一:

  let obj={a:1,b:2}
  let arr = []
  let x=Object.entries(obj)//[["a", 1],["b", 2]]
  arr=x.map(item=>{
      return item[1]
  })
  console.log(arr)//[1,2]

• 方法二:

  let obj={a:1,b:2}
  let arr = []
  for (let i in obj) {
      arr.push(obj[i]); //属性
      //arr.push(obj[i]); //值
  }
  console.log(arr);//[1,2]

• 方法三:

  let obj={a:1,b:2}
  let arr = Object.values(obj)
  console.log(arr);//[1,2]
