此时,我们可以使用正则表达式: constisMatchPattern=(str:string,pattern:string):boolean=>{constregex=newRegExp(pattern);returnregex.test(str);};console.log(isMatchPattern("Hello, World!","Hello"));// 输出: trueconsole.log(isMatchPattern("Hello, World!","world"));// 输出: false 1. 2. 3...

const regex = new RegExp(searchTerm, "i"); return input.filter(function(arrayElement) { return arrayElement.url.match(regex); }); } filterByTerm("input string", "java"); 如果你现在不明白其中的逻辑,也不要担心。在几行之后,我们来看看这个函数的参数以及它们是如何使用的。仅通过查看代码,您就...

Let's pretend Room.id should be a UUID encoded as a string. const r: Room = { id: Matchers.uuid(), // Type 'RegexMatcher' is not assignable to type 'string'. foo: { a: "example" } }; So in order to use this, Matchers.uuid() needs to return something that looks like a ...
This is a PERFECT application of the regex-validated string feature. Possible syntax using a matchof keyword: import { IJSONSchema, IJSONSchemaMap } from 'vs/base/common/jsonSchema'; export const UnscopedKeyPtn: string = '^[^\\[\\]]*$'; export type UnscopedKey = string & matchof Reg...
