javascript - reactjs and rendering plain HTML - Stack Overflow

First of all I'm totally new to react so I'm not sure if my code is already written the "react way".

So far I've created a couple of react classes which render a Bootstrap Modal. To set the initial states I call an Ajax function within the ponentsDidMount function. This works fine until I try to insert plain HTML into the modal body.

The server request works fine and I get plain HTML code in my this.state.data.content but if I try to insert this into the modal body I receive following error:

Error: Invariant Violation: Objects are not valid as a React child (found: object with keys {__html}). If you meant to render a collection of children, use an array instead or wrap the object using createFragment(object) from the React add-ons.

Does anyone know how to fix this? Am I even doing the right thing here?

Thanks!

• Are you supposed to close the <Modal.Body> tag? I think the code where you set the dangerouslySetInnerHTML={this.rawMarkup()} should be a property of the Modal.Body rather than a "child" – Icepickle Commented Dec 29, 2015 at 14:29
• This is how ReactBootstrap has done its markup. But you are right that in this case I need an additional <div> tag to get it working. – Flo Ragossnig Commented Dec 29, 2015 at 14:58

Well, as it seems, you are missing a div-tag where you wish to render your raw html

considering changing the Modal.Body code like this

var L5fmModalBody = React.createClass({
    rawMarkup: function() {
        return { __html: this.props.content };
    },
    render: function() {
        return(
            <Modal.Body>
                <div dangerouslySetInnerHTML={createMarkup()} />
            </Modal.Body>
        );
    }
});

otherwise the rendering gets broken because your markup cannot really be set as a child on the Modal.Body element
