React.createElement 接受散布的“儿童”参数
React.createElement
var d = React.DOM; React.createElement(LabeledElement, {label: "Foo"}, d.input({value: "foo"}) )
但我找不到有关如何实际使用它的任何文档
var LabeledElement = React.createClass({ render: function() { return d.label({} ,d.span({classNames: 'label'}, this.props.label) , //How to place children here? } })
我确信这是一个非常简单的答案。
通过JSX嵌套或通过的third +参数传递给组件的子代在组件中React.createElement显示为this.props.children:
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"}) ) ); } });
