I have an array of urls like this:
[
'https://subdomain1.example.com/foo-bar/',
'https://subdomain2.example.com/foo-bar',
'https://subdomain2.example.com/foo-bar',
'https://subdomain2.example.com/foo-bar',
'https://subdomain2.example.com/foo-bar'
]
I need to search inside it to match the user input with the subdomain part of the url, I'm trying with thism line of code to achive it:
const searched = urlList.find( el => el.includes( match[1].toLocaleLowerCase() ) )
console.log(searched.length)
If the input is find, I need to replace the second part of the url, in my case /foo-bar with /foo-baz or /foo-baz-bar to obtain a response for the user that is something like https://subdomain2.example.com/foo-bar-baz/.
At the moment I'm not sure how to proceed, is there any function in JS that can help me?
You can simply achieve that with a single line of code.
const urlList = [
'https://subdomain1.example.com/foo-bar/',
'https://subdomain2.example.com/foo-bar',
'https://subdomain2.example.com/foo-bar',
'https://subdomain2.example.com/foo-bar',
'https://subdomain2.example.com/foo-bar'
];
const findSubString = 'foo-bar';
const replaceSubString = 'foo-baz';
const res = urlList.map((url) => url.replace(findSubString, replaceSubString));
console.log(res);function foo() {
let a = ['https://subdomain1.example.com/foo-bar/', 'https://subdomain2.example.com/foo-bar', 'https://subdomain2.example.com/foo-bar', 'https://subdomain2.example.com/foo-bar', 'https://subdomain3.example.com/foo-bar'];
let seed = 'subdomain2.example.com';
let repl = 'whatever';
for (let i = 0; i < a.length; i++) {
let e = a[i];
let r = e.match(/\/\/([^\/]+)/);
if (r[1] == seed) {
a[i] = e.replace(/(?<=\.\w{3}\/)[a-zA-Z0-9_-]+/, repl);
}
}
//document.getElementById("jj").value = JSON.stringify(a);
console.log(JSON.stringify(a));
}
I've found a simple solution and solved the problem Here is my snippet for everyone that in future that need the same thing
const searched = urlList.find( el => el.includes( match[1].toLocaleLowerCase() ) )
const url = new URL(searched)
const host = url.host
const responseURL = `https://www.${host}${responsePath}`
