suppose we have this URL "/user/id" .
let url = "/user/id"
so I need to split this urls and make an individual url . somethig like this:
["/", "/user", "/user/id"]
I can split this with .split("/").I think I need some forEach() after spliting but I cant get it right.
Actually it is way easier if you use indexOf to find the slashes and .slice to get the parts:
const result = ["/"];
let pos = 1;
while(true) {
pos = url.indexOf("/", pos + 1);
if(pos < 0) break;
result.push(url.slice(0, pos + 1));
}
result.push(url);
Or the "functional approach" would be:
url.split("/").map((_, i, arr) => arr.slice(0, i + 1).join("/") || "/");
while(pos >= 0) instead of a break?
(pos + 1) || url.length, but I prefer the more readable version.GOTO :D I would probably used split and a basic for loop for that thoughFor-loop solution:
https://jsfiddle.net/c9asnfw4/1/
let url = '/user/id',
result = ['/'],
parts = url.split('/');
for(let i = 1; i < parts.length; i++) { // Skip first /
const part = parts[i];
if(i === 1) { // Start slash is already existing
result.push(result[i-1] + part);
} else if(i > 1) {
result.push(result[i-1] + '/' + part);
}
}
Output
(3) ["/", "/user", "/user/id"]
EDIT: Slightly shortened:
let url = '/user/id',
result = ['/'],
parts = url.split('/');
for(let i = 1; i < parts.length; i++) { // Skip first /
result.push( (result[i-1]) + (i > 1 ? '/' : '') + parts[i] );
}
