Question

I’m trying to initiate a class depending on two conditions, if the class hasn’t been initiated and if a class to which all the methods are applied is present in the markup :

if (!window.Recipes && !$('#page').find('#recipesSearchResults').length) {
    return window.Recipes = new Recipes;
} else {
    return true;
}

Is the above statement correct ? Or am I missing something ?

Answer 1

!$('#page').find('#recipesSearchResults').length will return true if the length of $('#page').find('#recipesSearchResults') is not 0.

However, #recipesSearchResults is an ID selector, and not a class selector.

…and if a class to which all the methods are applied is present in
the markup

You should change this to .recipesSearchResults:

!$('#page').find('.recipesSearchResults').length
