1. hashHistory.push传参

hashHistory.push({
        pathname: '/apartmentReserve/'+id,
        query: {
            name: name,
            price: price
        },
    })  

跳转之后页面接收参数

componentWillMount(){
    apartmentData={
        apartmentId:this.props.params.apartmentId,
        name:this.props.location.query.name,
        price:this.props.location.query.price
    }
}

2. input设置默认值

//text类型
<input  type="text" defaultValue={ 默认值 } />
//checkbox类型
<input type="checkbox" defaultChecked="true" />

3. 定时触发事件,setTimeout

class A extends React.Component{
    handleChange(target){
        var that = this;
        if(this.timer){
            clearTimeout(this.timer);
        }
        this.timer = setTimeout(()=>{
            that.setState({
                xxx:target.value
            });
        },500); 
    }
    render(){
        return(
            <input onChange={this.handleChange} xxxxxx />
        )
    }
    
}
