我的问题真的很简单,您注意到我在这里有一个称为frameStyle的css变量。
var Frame = React.createClass({
getInitialState: function() {
return {hover: false}
},
toggleHover: function(e) {
this.setState({
hover: !this.state.hover
})
},
render: function() {
if (this.state.hover){
linkStyle = "blue";
}else{
linkStyle = "red";
}
var frameStyle = {
width: 100,
height: 100,
backgroundColor: {this.props.linkStyle}
};
return (
<div onMouseEnter={this.toggleHover} onMouseLeave={this.toggleHover} style={frameStyle}>
</div>
);
}
});
如果要使用ES6编写组件,如何添加类似内容?如果有人能指出正确的方向,我将不胜感激!
最佳答案
If I have understood your question you want to create component using extending class in react ja.
import React from ‘react’;
class Frame extends React.component{
constructor(props){
super(props);
this.props = props;
this.state = { hover: false}
},
toggleHover = (e) =>{
this.setState({
hover: !this.state.hover
})
},
render() {
if (this.state.hover){
linkStyle = "blue";
}else{
linkStyle = "red";
}
var frameStyle = {
width: 100,
height: 100,
backgroundColor: {this.props.linkStyle}
};
return (
<div onMouseEnter={this.toggleHover} onMouseLeave={this.toggleHover} style={frameStyle}>
</div>
);
}
}
