Question

I would like to check if the current page has an anchor

so I am using this

var qs = window.location.hash;

then checking if qs is not an empty string

if (qs !== '') {

Is this the correct way to do that? It seems to work, but I am confusing myself reading about JavaScript’s various ways to check for null/undefined/empty string.

Answer 1

• window.location.hash only contains inner page links/anchors (those that follow a hash (#) symbol)
• window.location.search contains the query string with a ? prefix

Using your conditional (if-statement) is fine. If the property is not populated it will be a blank string.
