javascript - Get first word of string

Okay, here is my code with details of what I have tried to do:

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
}

So what should I do there? :

What I want to get is :

  • firstword[0] will give "Hello"

  • firstword[1] will give "sss"

  • firstword[2] will give "mmm"

Use regular expression

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

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

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