根据空格拆分字符串并在angular2中读取它 [英] Split string based on spaces and read that in angular2

问题描述

我正在angular2中创建一个管道，我想在白色空间上分割字符串，然后再将其读取为数组。

I am creating a pipe in angular2 where I want to split the string on white spaces and later on read it as an array.

let stringToSplit = "abc def ghi";
StringToSplit.split(" ");
console.log(stringToSplit[0]);

当我记录此内容时，我总是得到 a作为输出。我要去哪里了？

When I log this, I always get "a" as output. Where I am going wrong?

推荐答案

进行了一些更改：

let stringToSplit = abc def ghi;
let x = stringToSplit.split（）;
console.log（x [0]）;

split 方法返回一个数组。而不是使用其结果，而是获取原始字符串的第一个元素。

The split method returns an array. Instead of using its result, you are getting the first element of the original string.
