javascript - ReactJs 中可重用的模态

Question

我正在尝试创建一个服务，该服务将显示确认对话框并捕获用户的操作(确认/取消)，并且可以在任何组件中以较少的尝试重复使用。

到目前为止我尝试过的(使用 React gateway 注入(inject)我的对话框)

我创建了一个类似的服务:

var createConfirm = function(options, onConfirm, onCancel) {
  options = options || {};
  var actions = [
    <FlatButton
      label="Cancel"
      primary={true}
      onClick={onCancel}
    />,
    <RaisedButton
      label="OK"
      primary={true}
      onClick={onConfirm}
    />,
  ];
  return (
    <Gateway into="confirm-modal">
      <Dialog
        title={options.title || 'Confirmation'}
        actions={actions}
        modal={true}
        open={true}
      >
        {options.content || 'Are you sure?'}
      </Dialog>
    </Gateway>
  )
}

export default createConfirm;

然后在我的组件中，我将其注入(inject)到 render() 函数中:

...
{
   _this.state.isOpen && _this.confirmable
}

每当我需要显示确认模式时，我都会打电话

this.confirmable = createConfirm({
  title: 'CONFIRM',
  content: 'Are you sure to do that'
}, function() {
  console.log('user confirm')
  _this.setState({
    isOpen: false
  });
}, function() {
  console.log('user cancel')
  _this.setState({
    isOpen: false
  })
});
this.setState({isOpen: true});

我的问题

如您所见，我关闭“确认”对话框的方法是将 isOpen 状态设置为 false，这样它就不会被渲染。这是一个小作弊，似乎不是关闭对话框的 native 方式(丢失离开动画，看起来很奇怪......)。

那么我如何实现一个可以完全控制对话框的服务呢？

谢谢!

var Modal = React.createClass({

    return <div className='modal-backdrop in' />;
  },

  modal: function() {
    var style = {display: 'block'};

            </button>
          </div>
        </div>
      </Modal>
    );
