问如何使用react将链接存储到变量中？

class ListPanel extends react.purecomponent {

    get_type1_link = () => {
        const item_data = this.props.item_data;
        const itemss = this.props.items;
        const {itemname, item_id} = item_data.properties;
        const filtered_item = items && items.find(item => item.id === 
        item_id); 
        const item_name = (filtered_item) ? filtered_item.itemname : 
        (itemname ? itemname : item_id);

        if (filtered_item) {
            return (<Link to={`/someurl/${item_data.properties.item_id}`}> 
            {item_name}</Link>);
        } else {
            return <span>{item_name}</span>;
        }
    };
    get_type1_link = () => {
        const item_data = this.props.item_data;
        let link;
        switch (item_data.type) {
            case 'type1':
                link = this.get_type1_link();
                break;
            case 'type2':
                link = this.get_type2_link();
                break;
            default:
                return link=window.location.href;
            }
            return link;
    };
    render = () => {
        const list_item = this.props.;
        return (
            <ListItem
                key={list_item.id}
                text={this.get_text}
                link={this.get_link}/>
    );
}

class ListItem extends react.purecomponent {
    render = () => {

        <li onClick={props.link}>
            <div className="text">
                    {this.props.text}
             </div>
        </li>
     }
 }
