JS 通过多个成对的分隔符拆分字符串

Question

I have this string that I split whenever it finds two colons.

"for exam:ple thi:s string turns into" ["for exam","pls thi", "s string turns into"]

I do this with:

text.split(/(:.*?:)/g)

Afterward I interpret a string as "inside" the delimiter if it contains the characters I expect and none of those I don't.

How do I make it also extract another delimiter like $$...$$ as well as the original:...: but also include the delimiter somewhere so I can use different logic for it?

For context I'm parsing text into different react components.:...: includes addresses to embed a certain component, while $$...$$ includes MathJax.

You can try this regex with particular checks for :...: and $$...$$ patterns

 const text = "for exam:ple thi:s string $$turns$$ into" const partialStrings = text.split(/(:.*?:|\$\$.*?\$\$)/g) for (const partialString of partialStrings) { if (partialString.startsWith(":")) { //TODO: Do your logic with `:...:` pattern console.log(partialString + " contains ':...:'") continue } if (partialString.startsWith("$$")) { //TODO: Do your logic with `$$...$$` pattern console.log(partialString + " contains '$$...$$'") continue } //no patterns console.log(partialString + " has no patterns") }

OLD ANSWER

You can simply split your string with :

 const data = "for exam:ple thi:s string turns into" console.log(data.split(":"))

If you want to have similar behavior for $$ and a reusable function, you can declare a function called splitBy

 const splitBy = (data, delimiter) => { return data.split(delimiter) } const data = "for exam$$ple thi$$s string turns into" console.log(splitBy(data, "$$"))
