.split() is not a function error
提问by user1584421
I have an array that i transformed it into text with array-to-txt module.
我有一个数组，我使用 array-to-txt 模块将其转换为文本。
Instead i wanted it transformed to a big string, but i wanted a newline after every index of the array (the afforementioned module does this automatically).
相反，我希望将其转换为一个大字符串，但我希望在数组的每个索引之后都有一个换行符（上述模块会自动执行此操作）。
So i wrote this:
所以我写了这个：
result.toString();
result = result.split(",").join("\n");
Where result is the array. It didn't work, so then i tried this:
结果是数组。它没有用，所以我尝试了这个：
result.toString();
var output = result.split(",").join("\n");
Still i get the TypeError: result.split is not a functionerror.
我仍然收到TypeError: result.split is not a function错误。

The problem you have is result.toString()doesn't modify the original array...it only returnsa string.
您遇到的问题是result.toString()不修改原始数组...它只返回一个字符串。
You would need something like:
你需要这样的东西：
var str = result.toString()
var output= str.split(',').join('\n');
However there is no need to convert to string and immediately back to array when all you really need is:
但是，当您真正需要的是：
var output = result.join('\n')
回答by kebek
to convert the array into string use var k = String(result); var outPut = k.split(',').join('\n');
将数组转换为字符串使用 var k = String(result); var outPut = k.split(',').join('\n');

const result = ['a','b','c'];
const data = result.join('\n');
console.log(data);
