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么对阵列做切割。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后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
底为什么系统会判定成length?有好心大神愿意教导小
弟吗?耐心看完谢谢大家

注意 split("") 和 split(" ") 的不同

我是希望可以显示kobe bryant两个字就好,听说无空格会把所有字母拆开不过发现不管有没有空格跑出来都一样www

你是在哪开发、执行程式的?

按照题目要求,你的 cutName function 里面应该要对传入的参数字串做事,而不是直接对 myArray 做动作。

对,就是会变成array[2],不太了解直接对参数字串做事该怎么写我看一下谢谢您

cutName should return an array by breaking up theinput string into individual words.<— 这是你贴的题目叙述。字串.split 本来就会回传阵列,你想从阵列再拼回字串可以用 .join,但目标如果只是显示字串,直接写 myArray[0] 就好,不需要切割又拼回来。
