javascript - 循环遍历字符串

Question

我想获取单词和之后显示的每个单词。

var s = "you have a good day and time works for you and I'll make sure to 
get the kids together and that's why I was asking you to do the needful and 
confirm"

for (var  i= 0 ; i <= 3; i++){
    var body = s;
    var and = body.split("and ")[1].split(" ")[0];
    body = body.split("and ")[1].split(" ")[1];
    console.log(and);
}

我该怎么做？!

Answer 1

最简单的事情可能是使用正则表达式查找“​​and”，后跟空格，后跟“单词”，例如 /\band\s*([^\s]+)/g:

var s = "you have a good day and time works for you and I'll make sure to get the kids together and that's why I was asking you to do the needful and confirm";
var rex = /\band\s*([^\s]+)/g;
var match;
while ((match = rex.exec(s)) != null) {
  console.log(match[1]);
}

您可能需要稍微调整一下(例如，\b ["word border"] 认为- 是您可能不想要的边界；并且单独地，您对“单词”的定义可能与 [^\s]+ 等不同)。
