reactjs - How to use `React.createElement` children parameter (without jsx)

Question

React.createElement takes a spread "children" parameter

var d = React.DOM;

React.createElement(LabeledElement, {label: "Foo"}, 
     d.input({value: "foo"})
)

but I can't find any documentation on how to actually use it

var LabeledElement = React.createClass({
    render: function() {
        return d.label({}
            ,d.span({classNames: 'label'}, this.props.label)
            , //How to place children here? 
    }
})

I'm sure this has a really really simple answer.

Answer 1

The children passed to a component, either via JSX nesting or via the third+ argument to React.createElement, shows up in the component as this.props.children:

var MyLabel = React.createClass({
  render: function() {
    return React.createElement("label", {className: "label"},
      React.createElement("span", {className: "label"}, this.props.label),
      this.props.children
    );
  }
});

var App = React.createClass({
  render: function() {
    return React.createElement(MyLabel, {label: "Here is the label prop"},
      React.createElement("div", {},
        React.createElement("input", {type: "text", value: "And here is a child"})
      )
    );
  }
});
