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>
