Set attribute without value
attr, attributes, javascript, jquery
Solution
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>
Reference - http://api.jquery.com/attr/#attr-attributeName-value
attr( attributeName , value )
Problem
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?
