是这样的,小弟最近觉得程式语言好像很有趣,就想来自学一下,不过在练习的时候真的
是挫折重重...绞尽脑汁了一个早上还是不知道该怎麽对阵列做切割。这边是问题
1、First, declare a variable named myArray and assign it to an empty array.
2、Now populate myArray with two strings:
Put your full name in the first string, and your favorite color in the second.
3、Next, declare a function named cutName. It should expect a parameter name.
cutName should return an array by breaking up the input string into individual
words.
4、Declare a new variable named myInfo and assign it to an empty object litera
l.
Add the following three key-value pairs to myInfo:
Key: fullName
Value: The result of calling cutName on the name string within myArray.
Key: favoriteColor
Value: The color within myArray.
Key: github
Value:If you have a github handle, enter it here as a string. If not, set this
to null instead.
我的程式是这样的:
var myArray = ["Kobe Bryant","red"];
var github = null
function cutName(name) {
var res = myArray[0].split("");
return res;
}
var myInfo = {
fullName : cutName(myArray[0]),
favoriteColor : myArray[1],
github : github
};
console.log(myInfo);
myInfo後面两个物件是正确的,但是名字切不出来啊!会变成Array(12)(超崩溃)!到
底为什麽系统会判定成length?有好心大神愿意教导小
弟吗?耐心看完谢谢大家

1F:推 eight0: 注意 split("") 和 split(" ") 的不同 02/22 05:51
2F:→ wawalandhoho: 我是希望可以显示kobe bryant两个字就好,听说无空 02/22 05:54
3F:→ wawalandhoho: 格会把所有字母拆开 02/22 05:54
4F:→ wawalandhoho: 不过发现不管有没有空格跑出来都一样www 02/22 05:55
5F:推 eight0: 你是在哪开发、执行程式的? 02/22 09:57
6F:→ brianwu1201: 按照题目要求,你的 cutName function 里面应该要对 02/22 11:06
7F:→ brianwu1201: 传入的参数字串做事,而不是直接对 myArray 做动作。 02/22 11:06
8F:→ wawalandhoho: eight0大,我是用Brackets 02/22 11:24
9F:→ wawalandhoho: 所以brianwu大,我现在应该怎麽做呢? 02/22 11:25
10F:→ wawalandhoho: 不好意思才刚碰JS三天,很多观念都还没有通 02/22 11:26
12F:→ brianwu1201: 给你参考 02/22 11:37
13F:→ wawalandhoho: 对,就是会变成array[2],不太了解直接对参数字串 02/22 11:39
14F:→ wawalandhoho: 做事该怎麽写 02/22 11:39
15F:→ wawalandhoho: 我看一下谢谢您 02/22 11:39
16F:→ brianwu1201: cutName should return an array by breaking up the 02/22 11:45
17F:→ brianwu1201: input string into individual words.<— 这是你贴 02/22 11:45
18F:→ brianwu1201: 的题目叙述。 02/22 11:45
19F:→ brianwu1201: 字串.split 本来就会回传阵列,你想从阵列再拼回字 02/22 12:01
20F:→ brianwu1201: 串可以用 .join,但目标如果只是显示字串,直接写 my 02/22 12:01
21F:→ brianwu1201: Array[0] 就好,不需要切割又拼回来。 02/22 12:02
22F:→ wawalandhoho: 太好了!运行成功了!谢谢您! 02/22 12:36
