我想有条件地显示和隐藏这个按钮组,这取决于从父组件传入的内容,看起来像这样:
<TopicNav showBulkActions={this.__hasMultipleSelected} />
__hasMultipleSelected: function() {
return false; //return true or false depending on data
}
var TopicNav = React.createClass({
render: function() {
return (
<div className="row">
<div className="col-lg-6">
<div className="btn-group pull-right {this.props.showBulkActions ? 'show' : 'hidden'}">
<button type="button" className="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-expanded="false">
Bulk Actions <span className="caret"></span>
</button>
<ul className="dropdown-menu" role="menu">
<li><a href="#">Merge into New Session</a></li>
<li><a href="#">Add to Existing Session</a></li>
<li className="divider"></li>
<li><a href="#">Delete</a></li>
</ul>
</div>
</div>
</div>
);
}
});
然而,{this.props。showBulkActions吗?'show': 'hidden'}。我做错什么了吗?
