1. 网页动画
在react中使用CSS3动画效果：
<!DOCTYPE html>
<html>
<head lang="en">
<Meta charset="UTF-8">
<title></title>
<script src="build/react-with-addons.js"></script>
<script src="build/JSXTransformer.js"></script>
<style>
.example-enter{
opacity: 0.01;
transition: opacity.5s ease-in;
}
.example-enter.example-enter-active{
opacity: 1;
}
.example-leave{
opacity: 1;
transition: opacity.5s ease-in;
}
.example-leave.example-leave-active{
opacity: 0.01;
}
</style>
</head>
<body>
<script type="text/jsx">
var ReactCSSTransitionGroup = React.addons.CSSTransitionGroup;
var TodoList = React.createClass({
getInitialState: function () {
return {
items: ['hello','world','click','me']
};
},handleAdd: function () {
var newItems = this.state.items.concat([prompt('Enter some text')]);
this.setState({items:newItems});
},handleRemove: function (i) {
var newItems = this.state.items;
newItems.splice(i,1);
this.setState({items:newItems});
},render: function () {
var items = this.state.items.map(function (item,i) {
return(
<div key={item} onClick={this.handleRemove.bind(this,i)}>
{item}
</div>
);
}.bind(this));
return (
<div>
<button onClick={this.handleAdd}>Add Item</button>
<ReactCSSTransitionGroup transitionName="example">
{items}
</ReactCSSTransitionGroup>
</div>
)
},});
React.render(
<TodoList></TodoList>,document.body);
</script>
</body>
