jquery how to check if url contains word?

Try:

if (window.location.href.indexOf("catalogue") > -1) { // etc

indexOf doesn't return true/false, it returns the location of the search string in the string; or -1 if not found.

Seeing as the OP was already looking for a boolean result, an alternative solution could be:

if (~window.location.href.indexOf("catalogue")) {
    // do something
}

The tilde (~) is a bitwise NOT operator and does the following:

~n == -(n+1)

In simple terms, the above formula converts -1 to 0, making it falsy, and anything else becomes a non-zero value making it truthy. So, you can treat the results of indexOf as boolean.
