react动态渲染组件

组件是不确定的，是一个变量传入的，可以使用如下方法渲染

export function insertModal(cfg){
    let {id,refKey,modal} = cfg;
    let ModalKey = modal || 'Modal';
    id = id || +new Date();
    let div = document.createElement('div');
    div.id = id;
    document.body.appendChild(div);
    refKey = refKey || 'myRef' + id;
    window[refKey + 'Ref'] = React.createRef();
    ReactDOM.render(React.createElement(ModalKey,{ref:window[refKey + 'Ref']}), div);
}
