Documentation not clear about how to prevent unmounting components

[andreynering]

Since I disabled Turbolinks, I was trying to prevent react_ujs behavior unmounting components on page unload.

The documentation says:

react_ujs will also scan DOM elements and call React.unmountComponentAtNode on page unload. If you want to disable this behavior, remove data-react-class attribute in componentDidMount.

But I don't know how to do that:

var MyComponent = React.createClass({
  ...
  componentDidMount: function() {
    // ???
  }
});

It would be nice if the documentation give an example.

I'm not actually doing this in my app, but I found it worked in a quick test:

var MyComponent = React.createClass({
  ...
  componentDidMount: function() {
    this.getDOMNode().parentElement.removeAttribute("data-react-class");
  }
});

Does that work for you?

Yes, this works perfectly.

Should this example go to the documentation?
