javascript - 获取字符串的第一个单词

Question

好的，这是我的代码，其中包含我尝试执行的操作的详细信息:

var str = "Hello m|sss sss|mmm ss";
//Now I separate them by "|"
var str1 = str.split("|");

//Now I want to get the first word of every split-ed sting parts:

for (var i = 0; i < codelines.length; i++) {
  //What to do here to get the first word of every spilt
}

那我应该怎么办呢？ :\

我想要得到的是:

• firstword[0] 将给出 "Hello"

• firstword[1] 将给出 "sss"

• firstword[2] 将给出 "mmm"

Answer 1

使用正则表达式

var totalWords = "foo love bar very much.";

var firstWord = totalWords.replace(/ .*/,'');

$('body').append(firstWord);
