JavaScript regex replace on hash

Question

I'm trying to do a replace on a hash so I can call a html file that matches its name.

For example:

var url = '/partials/' + ( hash.replace( /^#/, '' ) || 'blank' ) + '.html';

and hash will be:

#/home/

at the moment it will only remove the #

what have I missed?

I think your code just replaces the # with nothing so it is removed — Huangism

It looks like you also want to remove the leading and trailing / as well. Try using a pattern like this:

/^#\/|\/$/g

For example:

var hash = '#/home/';
var url = '/partials/' + ( hash.replace( /^#\/|\/$/g, '' ) || 'blank' ) + '.html';
console.log(url); // "/partials/home.html"

Or possibly try using match instead of replace, like this:

var hash = '#/home/';
var url = '/partials/' + ( hash.match(/\w[\w/]*\w/) || 'blank' ) + '.html';
console.log(url); // "/partials/home.html"
