HTML Preparation code:

<!--your preparation HTML code goes here-->

Script Preparation code:

const testPath = "http://foo.org/smth/teachers/ad0bfc84-3d16-46c3-948c-2f8d08976fcc/bar";
const userIdPathSegments = ['students', 'teachers'];
const userIdPathSegmentRegexps = [new RegExp(/\/students\/(?<userId>\w+)/), new RegExp(/\/teachers\/(?<userId>\w+)/)];
const userIdPathSegments2 = ['/students/', '/teachers/'];

Tests:

split
const pathParts = testPath.split('/').filter(p => p); const userIdIndex = pathParts.findIndex(p => userIdPathSegments.some(aPN => p === aPN)); if (userIdIndex >= 0 && pathParts.length > userIdIndex + 1) { pathParts[userIdIndex + 1]; }
regex
for (let i = 0; i < userIdPathSegmentRegexps.length; i++) { const match = testPath.match(userIdPathSegmentRegexps[i]); if (Array.isArray(match) && match.length == 2 && match[1].length > 0) { match[1]; } }
string includes
for (let i = 0; i < userIdPathSegments2.length; i++) { const segment = userIdPathSegments2[i]; const index = testPath.indexOf(segment); if (index >= 0 && index + segment.length < testPath.length) { return testPath.endsWith(segment + "ad0bfc84-3d16-46c3-948c-2f8d08976fcc") || testPath.includes(segment + "ad0bfc84-3d16-46c3-948c-2f8d08976fcc" + '/'); } }
