使用splice()添加项目
- 使用接头()函数,必须删除从阵列的第一2个元件
arr
,并用替换它们DarkSalmon
和BlanchedAlmond
。 - 请记住,拼接功能最多可以使用三个参数。
例:
arr.splice(0, 1, "Two");
/* The first two paramemters are the same as they were in the previous challenge.
`0` will start the `splice()` function off at index 0.
The second parameter `1` will remove only 1 variable from the array.
The final variable "Two" will replace the variable in arr[0].
Note: The final parameter can take more than 1 arguement.
*/
解:
function htmlColorNames(arr) {
// change code below this line
arr.splice(0, 2, "DarkSalmon", "BlanchedAlmond");
// change code above this line
return arr;
}
// do not change code below this line
console.log(htmlColorNames(['DarkGoldenRod', 'WhiteSmoke', 'LavenderBlush', 'PaleTurqoise', 'FireBrick']));
