这个答案中有一个模式 https://stackoverflow.com/a/26789089/883571 正在创建通过将其附加到 <body>
的基于 React 的 Modal.但是,我发现它与 React 提供的过渡插件不兼容.
There is a modal in this answer https://stackoverflow.com/a/26789089/883571 which is creating a React-based Modal by appending it to <body>
. However, I found it not compatible with the transition addons provided by React.
如何创建一个带过渡的(进入和离开时)?
How to create one with transitions(during enter and leave)?
在 react conf 2015 上,Ryan Florence 展示了使用门户.以下是创建简单 Portal
组件的方法...
At react conf 2015, Ryan Florence demonstrated using portals. Here's how you can create a simple Portal
component...
var Portal = React.createClass({
render: () => null,
portalElement: null,
componentDidMount() {
var p = this.props.portalId && document.getElementById(this.props.portalId);
if (!p) {
var p = document.createElement('div');
p.id = this.props.portalId;
document.body.appendChild(p);
}
this.portalElement = p;
this.componentDidUpdate();
},
componentWillUnmount() {
document.body.removeChild(this.portalElement);
},
componentDidUpdate() {
React.render(<div {...this.props}>{this.props.children}</div>, this.portalElement);
}
});
然后,您通常可以在 React 中执行的所有操作都可以在门户内部执行...
and then everything you can normally do in React you can do inside of the portal...
<Portal className="DialogGroup">
<ReactCSSTransitionGroup transitionName="Dialog-anim">
{ activeDialog === 1 &&
<div key="0" className="Dialog">
This is an animated dialog
</div> }
</ReactCSSTransitionGroup>
</Portal>
你也可以看看 Ryan 的 react-modal,虽然我实际上没有使用它,所以我不知道它与动画效果如何.
You can also have a look at Ryan's react-modal, although I haven't actually used it so I don't know how well it works with animation.
