I’m wanting to add a class to the body tag without waiting for the DOM to load, but I’m wanting to know if the following approach would be valid. I’m more concerned with validity than whether the browsers support it for now.

<body>   $('body').addClass('active');   ... </body>

  1. The .elementReady() plugin seems to be pretty close to what you’re looking for.

    It operates by using a setInterval loop, that exits as soon as document.getElementById() returns an element for a given id.

    You could probably do a slight modification of that plugin (or commit an update/patch) to allow for generic selectors (at least for ‘tagNames’) instead of just ids.

    I don’t believe there is any truly reliable cross-browser compatible way to address an element before it’s loaded – other than this sort of setInterval hacking

    Unless you are able to place your javascript command inside the target element like @JasonBunting suggests.
