Trying to use React.DOM to set body styles

Question

How can I use React.DOM to change styles on HTML body?

I tried this code and it's not working:

var MyView = React.createClass({   render: function() {     return (       <div>         React.DOM.body.style.backgroundColor = "green";         Stuff goes here.       </div>     );   } }); 

If you execute this from the browsers console it works (but I need it working in ReactJS code): document.body.style.backgroundColor = "green";

Also see this question for similar but different solution: Change page background color with each route using ReactJS and React Router?

Assuming your body tag isn't part of another React component, just change it as usual:

document.body.style.backgroundColor = "green"; //elsewhere.. return (   <div>     Stuff goes here.   </div> ); 

It's recommended to put it at componentWillMount method, and cancel it at componentWillUnmount:

componentWillMount: function(){     document.body.style.backgroundColor = "green"; }  componentWillUnmount: function(){     document.body.style.backgroundColor = null; }
