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>
标签,它代表在命名的自定义标签中给出的子元素,以及它们应该如何嵌入到自定义标签的最终实现中(它就像一个门户网站) )。似乎当使用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-dialog
Polymer元素通过React时,就会出现这个问题:
<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指示的方式执行此操作(将标记放在HTML中开头),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。
有谁知道如何将Polymer与React实际匹配?
答案 0 :(得分:2)
您是否尝试将<paper-dialog>
包装到另一个反应组件中,然后将其送到ReactDOM
这样的
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'));
