587d7daa367417b2b2512b6b 使用 split 方法将字符串拆分成数组 1 18305 split-a-string-into-an-array-using-the-split-method

--description--

split方法用于把字符串分割成字符串数组,接收一个分隔符参数,分隔符可以是用于分解字符串或正则表达式的字符。举个例子,如果分隔符是空格,你会得到一个单词数组;如果分隔符是空字符串,你会得到一个由字符串中每个字符组成的数组。

下面是两个用空格分隔一个字符串的例子,另一个是用数字的正则表达式分隔:

var str = "Hello World";
var bySpace = str.split(" ");
// Sets bySpace to ["Hello", "World"]

var otherString = "How9are7you2today";
var byDigits = otherString.split(/\d/);
// Sets byDigits to ["How", "are", "you", "today"]

因为字符串是固定的,split方法可以更简单的操作它们。

--instructions--

splitify函数中用split方法将str分割成单词数组,这个方法应该返回一个数组。单词不一定都是用空格分隔,所以数组中不应包含标点符号。

--hints--

应该使用split方法。

assert(code.match(/\.split/g));

splitify('Hello World,I-am code')应返回['Hello', 'World', 'I', 'am', 'code']

assert(
  JSON.stringify(splitify('Hello World,I-am code')) ===
    JSON.stringify(['Hello', 'World', 'I', 'am', 'code'])
);

splitify('Earth-is-our home')应返回['Earth', 'is', 'our', 'home']

assert(
  JSON.stringify(splitify('Earth-is-our home')) ===
    JSON.stringify(['Earth', 'is', 'our', 'home'])
);

splitify('This.is.a-sentence')应返回['This', 'is', 'a', 'sentence']

assert(
  JSON.stringify(splitify('This.is.a-sentence')) ===
    JSON.stringify(['This', 'is', 'a', 'sentence'])
);

--seed--

--seed-contents--

function splitify(str) {
  // Only change code below this line


  // Only change code above this line
}
splitify("Hello World,I-am code");

--solutions--

function splitify(str) {
  // Only change code below this line
  return str.split(/\W/);
  // Only change code above this line
}
