拆分 Javascript 字符串

Question

可用时间： 周一周二周三 8-12 12-5 其他类型的联系人： 短信 不可用时间： 周四 8-12

我想将上面的字符串拆分为三个单独的数组第一个数组 = [星期一周二周三 8-12 12-5]

第 2 个数组 = [SMS]

第 3 个数组 = [星期四 8-12 ]

我试过使用拆分功能，但是没用！感谢您的帮助。提前致谢

Answer 1

只要字符串的粗体部分始终相同，您就可以尝试这样的操作：

var s = "Available Times: Monday Tuesday Wednesday 8-12 12-5 Other type of contact: SMS Unavailable Times: Thursday 8-12"
var arr = []

arr.push(s.split(" Unavailable Times: ")[1])
s = s.split(" Unavailable Times: ")[0]

arr.unshift(s.split(" Other type of contact: ")[1])
s = s.split(" Other type of contact: ")[0]

arr.unshift(s.split("Available Times: ")[1])

console.log(arr)

Answer 2

使用拆分 regex

let str = 'Available Times: Monday Tuesday Wednesday 8-12 12-5 Other type of contact: SMS Unavailable Times: Thursday 8-12'
let replace = str.replace('Available Times: ', '');
let arr = replace.split(/ Other type of contact: | Unavailable Times: /)
console.log(arr);

Answer 3

Does the OP mean ["Monday Tuesday Wednesday 8-12 12-5"] or ["Monday", "Tuesday", "Wednesday", "8-12", "12-5"] and likewise for the two remaining ones ?.. or ... does the OP even mean a single array with three string items like ... ["Monday Tuesday Wednesday 8-12 12-5", "SMS", "Thursday 8-12"]. The question arises since the OP did not provide a proper syntax of the expected result and three separate arrays each with just a single item does not make any sense.

如果只是将信息提取为三个分隔的字符串值，则以下正则表达式可能会有所帮助...

/Available Times:\s*(?<available>.*?)\s+Other type of contact:\s*(?<contact>.*?)\s+Unavailable Times:\s*(?<unavailable>.*?)\s*$/

用简单的String.prototype.match one would receive an array which holds the match itself followed by the results of the 3 capturing groups
为了只接收一个没有 匹配的数组 需要 slice 数组。
也可以利用named capturing groups via RegExp.prototype.exec and some Destructuring Assignment

const sampleData =
  'Available Times: Monday Tuesday Wednesday 8-12 12-5 Other type of contact: SMS Unavailable Times: Thursday 8-12';

// see ... [https://regex101.com/r/jVedS4/1]
const regXGroups =
  /Available Times:\s*(?<available>.*?)\s+Other type of contact:\s*(?<contact>.*?)\s+Unavailable Times:\s*(?<unavailable>.*?)\s*$/;

console.log(
  sampleData.match(regXGroups)
);
console.log(
  sampleData.match(regXGroups).slice(1)
);

const {
  unavailable,
  available,
  contact,
} = regXGroups.exec(sampleData)?.groups ?? {};

console.log([available, contact, unavailable]);
