鉴于上面的文本，我想将“By”之后、SPACE 之前的每个单词插入数组。结果一定是这样的:

name[0] = "Greili"
name[1] = "ToneBob"
name[2] = "hela222"

Answer 1

这是一个快速split和 reduce :

var arr = str.split("By ").reduce(function(acc, curr) {
  curr && acc.push(curr.split(" ")[0]); return acc;
}, []);

结果:

["Greili", "ToneBob", "hela222", "NovaSplitz"]
