請(qǐng)教一個(gè)簡(jiǎn)單一些的javascript的問(wèn)題，關(guān)于變量的轉(zhuǎn)換

有只小跳蛙 2018-07-06 07:19:12

怎么把一個(gè)數(shù)組轉(zhuǎn)換成若干個(gè)單獨(dú)的變量，比如arr = [1,2,3,4]轉(zhuǎn)換成arr1 = 1arr2 = 2arr3 = 3arr4 = 4

 var [a,b,c,d]=[1,2,3,4]
console.log(a,b,c,d)

 arr = [1,2,3,4]
for(var i=0;i<arr.length;i++)window['arr'+(i+1)]=arr[i]
console.log(arr1,arr2,arr3,arr4)

let arr = [1, 2, 3, 4];
for (let i = 0; i < arr.length; i++) {
window['arr' + i] = arr[i];//在全局對(duì)象window上新增一個(gè)屬性
}
console.log('arr0=====', arr0);
console.log('arr1=====', arr1);
console.log('arr2=====', arr2);
console.log('arr3=====', arr3);
