Find element with jquery and assign css class

Question

I am trying to find a div with a certain css class and assign to body a class

if ($('div').class(home)) {
    $("body").addClass("mobile-bg");
}

But its not working

Why did you use .class(), when, for example, Google suggests a lot of links with .hasClass() description on jquery check element has class request? — Regent

you need to use .hasClass() not class()

if ($('div').hasClass('home')) {
    $("body").addClass("mobile-bg");
}

this code mean .. if div has class="home" add class="mobile-bg" to body

Or as an alternative to Mohamed's solution,

if ($('div.home').length > 0) {
    $("body").addClass("mobile-bg");
}

This checks if there are any <div> elements with the class home, and if any exist, it adds the mobile-bg class to the <body>.
