How to use split in javascript

Question

/abc/def/hij/lmn.o // just a raw string for example dont know what would be the content

I want only /abc/def/hij part of string how do I do that.

I tried using .split() but did not get any solution.

If you want to remove the particular string /lmn.o, you can use replace function, like this
```
console.log(data.replace("/lmn.o", ""));
# /abc/def/hij
```

If you want to remove the last part after the /, you can do this

console.log("/" + data.split("/").slice(1, -1).join("/"));
# /abc/def/hij

you can do

var str = "/abc/def/hij/lmn.o";
var dirname = str.replace(/\/[^/]+$/, "");

Alternatively:

var dirname = str.split("/").slice(0, -1).join("/");

See the benchmarks

x.substring(0,x.lastIndexOf("/")); My answer seems to be simple. Yet this is the best answer. Keeps me thinking if I got it wrong :D

@faiz, your answer is completely fine. In fact, in the benchmark I setup, yours performs the best.

Using javascript

var x = '/abc/def/hij/lmn.o';
var y = x.substring(0,x.lastIndexOf("/"));
console.log(y);

var s= "/abc/def/hij/lmn.o"
var arr= s.split("/");

after this, use

arr.pop();

to remove the last content of the array which would be lmn.o, after which you can use

var new_s= arr.join("/");

to get /abc/def/hij
