How do I set a data attribute without adding a value in jQuery? I want this:

<body data-body>

I tried:

$('body').attr('data-body'); // this is a getter, not working

$('body').attr('data-body', null); // not adding anything

Everything else seems to add the second arguments as a string. Is it possible to just set an attribute without value?

The attr() function is also a setter function. You can just pass it an empty string.

$('body').attr('data-body','');

An empty string will simply create the attribute with no value.

<body data-body>

attr( attributeName , value )
