Javascript – Rendering raw html with reactjs

javascriptreactjs

So is this the only way to render raw html with reactjs?

// http://facebook.github.io/react/docs/tutorial.html
// tutorial7.js
var converter = new Showdown.converter();
var Comment = React.createClass({
  render: function() {
    var rawMarkup = converter.makeHtml(this.props.children.toString());
    return (
      <div className="comment">
        <h2 className="commentAuthor">
          {this.props.author}
        </h2>
        <span dangerouslySetInnerHTML={{__html: rawMarkup}} />
      </div>
    );
  }
});

I know there are some cool ways to markup stuff with JSX, but I am mainly interested in being able to render raw html (with all the classes, inline styles, etc..). Something complicated like this:

<!-- http://getbootstrap.com/components/#dropdowns-example -->
<div class="dropdown">
  <button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown" aria-expanded="true">
    Dropdown
    <span class="caret"></span>
  </button>
  <ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu1">
    <li role="presentation"><a role="menuitem" tabindex="-1" href="#">Action</a></li>
    <li role="presentation"><a role="menuitem" tabindex="-1" href="#">Another action</a></li>
    <li role="presentation"><a role="menuitem" tabindex="-1" href="#">Something else here</a></li>
    <li role="presentation"><a role="menuitem" tabindex="-1" href="#">Separated link</a></li>
  </ul>
</div>

I would not want to have to rewrite all of that in JSX.

Maybe I am thinking about this all wrong. Please correct me.

There are now safer methods to render HTML. I covered this in a previous answer here. You have 4 options, the last uses dangerouslySetInnerHTML.

Methods for rendering HTML

  1. Easiest - Use Unicode, save the file as UTF-8 and set the charset to UTF-8.

    <div>{'First ยท Second'}</div>

  2. Safer - Use the Unicode number for the entity inside a Javascript string.

    <div>{'First \u00b7 Second'}</div>

    or

    <div>{'First ' + String.fromCharCode(183) + ' Second'}</div>

  3. Or a mixed array with strings and JSX elements.

    <div>{['First ', <span>&middot;</span>, ' Second']}</div>

  4. Last Resort - Insert raw HTML using dangerouslySetInnerHTML.

    <div dangerouslySetInnerHTML={{__html: 'First &middot; Second'}} />
