使用React渲染带有子内容的Polymer 1.0元素

Question

我一直在努力解决这个问题,最后我设法追查问题的根源,但我不知道如何解决它!

考虑在React渲染方法中渲染Polymer的元素:

ReactDOM.render(
    <paper-button>Ok</paper-button>,
    document.getElementById('root')
);

以前的代码工作正常,因为<paper-button>没有子元素.但是以下示例不起作用:

ReactDOM.render(
    <paper-dialog>
        <h2>Header</h2>
        <paper-dialog-scrollable>
            Lorem ipsum...
        </paper-dialog-scrollable>
        <div class="buttons">
            <paper-button dialog-dismiss>Cancel</paper-button>
            <paper-button dialog-confirm>Accept</paper-button>
        </div>
    </paper-dialog>,
    document.getElementById('root')
);

因为<paper-dialog>有几个子元素.在Polymer的库中有一个<content>标记,它表示在命名的自定义标记中给出的子元素,以及它们应该如何嵌入到自定义标记的最终实现中(它就像一个门户网站).看起来当使用React将Polymer元素添加到文档中时,子元素不会通过门户传递!

当提到的paper-dialogPolymer元素通过React时,这就是出现的结果:

<paper-dialog data-reactroot="">
    <h2>Header</h2>
    <paper-dialog-scrollable
        class="x-scope paper-dialog-scrollable-0 no-padding scrolled-to-bottom">
        Lorem ipsum...
    </paper-dialog-scrollable>
    <div>
        <paper-button
            role="button" tabindex="0"
            animated="" aria-disabled="false"
            elevation="0" dialog-dismiss="true"
            class="x-scope paper-button-0">
            Cancel
        </paper-button>
        <paper-button
            role="button" tabindex="0"
            animated="" aria-disabled="false"
            elevation="0" dialog-confirm="true"
            class="x-scope paper-button-0">
            Accept
        </paper-button>
    </div>
</paper-dialog>

如果我按照google指示的方式进行操作(将标签放在HTML中开始),这就是dom树的样子:

<paper-dialog>
    <h2>Header</h2>
    <paper-dialog-scrollable
        class="x-scope paper-dialog-scrollable-0 no-padding can-scroll">
        <div id="scrollable"
            class="scrollable style-scope paper-dialog-scrollable fit">
            Lorem ipsum...
        </div>
    </paper-dialog-scrollable>
    <div class="buttons">
        <paper-button
            role="button" tabindex="0"
            animated="" aria-disabled="false"
            elevation="0" dialog-dismiss=""
            class="x-scope paper-button-0">
            Cancel
        </paper-button>
        <paper-button
            role="button" tabindex="0"
            animated="" aria-disabled="false"
            elevation="0" dialog-confirm=""
            class="x-scope paper-button-0">
            Accept
        </paper-button>
    </div>
</paper-dialog>

粗体部分是不一致的部分.

有谁知道如何实际匹配Polymer与React？

您是否尝试过将其包装<paper-dialog>到另一个反应组件中，然后将其提供给ReactDOM这样的组件

var PaperDialog = React.createClass({
    render: function () {
        return (
            <paper-dialog>
                <h2>Header</h2>
                <paper-dialog-scrollable>
                    Lorem ipsum...
                </paper-dialog-scrollable>
                <div class="buttons">
                    <paper-button dialog-dismiss>Cancel</paper-button>
                    <paper-button dialog-confirm>Accept</paper-button>
                </div>
            </paper-dialog>);
    }
});

ReactDOM.render(<PaperDialog />, document.getElementById('root'));
