How check if body has a specific class with JavaScript?

Question

How can I check if body has specific class? This is my case:

Answer 1

You can use the Mozilla classList for this.

The linked page also has a cross-browser solution.

Answer 2

jQuery.hasClass works for me...

non jQuery answer, try if( document.body.className.match('foo') ) { ... }

Answer 3

document.getElementsByTagName("body")[0].className.match(/foo/)

Answer 4

This returns a string of true or false when looking for a specific body class using jQuery's .hasClass:

$("body").hasClass("your-class-name").toString();

Answer 5

function hasClass(ele,cls) {
     return ele.className.match(new RegExp('(\\s|^)'+cls+'(\\s|$)'));
}

if(hasClass(document.getElementById("test"), "test")){//do something};

maybe this helps you :-)

With the use of jQuery it would be easier and less code but nevermind !

Answer 6

This returns a string of true or false when looking for a specific body class using jQuery's .hasClass:

if ($("body").hasClass("modal-open")) {
                        $("body").removeClass("modal-open");
                    }
