How to extract a word from a string in Javascript.

Question

The string is "www.Desktop/hh/template.html"
I wanted to extract the word template with out counting it my self but I couldn't find a way to get the last word 'e' or if there is a method. Thanks.

Answer 1

Or if you're wanting to always get the name of the html, php etc file no matter how deep the file is provided it is part of the URL then you can use:

let myLink ="www.Desktop/hh/template.html";
let start_pos = myLink.lastIndexOf('/') + 1;
let end_pos = myLink.lastIndexOf('.');
let sliced = myLink.slice(start_pos,end_pos);
alert(sliced);

Answer 2

string.match(/\/.*?(?=\.html?)$/gmi)[0].replace(/^\//gmi, '')
//use regexes for hard situations

Answer 3

You could use:
.slice()
.search()
.split()
Google these and see which one suits you best

Answer 4

You could also use indexOf().

Answer 5

You could do this but if the link gets any extra / or . then this will not return template:

var str = myLink.split("/")[2].split(".")[0];
alert(str);

Answer 6

This simplifies your current code.

let myLink ="www.Desktop/hh/template.html";
let word="template";
let start_pos = myLink.indexOf(word);
let end_pos =start_pos + word.length;
let sliced = myLink.slice(start_pos,end_pos);
alert(sliced);

Answer 8

Finally got it in a very messy way. I may change it to function soon. but there is probably a simpler way to do this.

ValentinHacker Never ever use Regex if you can avoid it. You can solve this problem here using simply lastIndexOf.
