锚标签(标签)onclick事件处理程序无法正常工作

Question

虽然我已经包括了onclick句柄一个由reactjs组件(名称renderLocationLink分量)的渲染方法返回的HTML标签,虽然渲染发生正确的onclick处理程序属性犯规出现在网页上所提供的HTML我希望无法解决问题,这是代码

var feedApp = React.createClass({
      getInitialState: function(){
        return {
          data : [
           {display_name:"Rao",content:"this is Rao post",links:['link1','link2','link3']},
           {display_name:"Sultan",content:"this is Sultans",links:['link4','link5','link6']},
           {display_name:"John",content:"this is John post",links:['link7','link8','link9']}
          ]
        }
      },
      fetchFeedsFromUrl: function(){
        console.log('Onclick triggered');
      },
      render: function(){
        return (<Feeds data={this.state.data} onClick={this.fetchFeedsFromUrl} />)
      }
})

var Feeds = React.createClass({

    render: function(){
      var onClickfunc = this.props.onClick; 
      var feeds = this.props.data.map(function(feed){
        return (
          <oneFeed  name={feed.display_name}  onClick={this.onClickfunc} content={feed.content}  links={feed.links} />
        )
      });
    return( 
      <div> {feeds} </div>  
    )
  }
})


var oneFeed = React.createClass({
      render: function() {
        return (
         <div> 
          <h3>{this.props.name}</h3>
          <renderLocationLink  onClick={this.props.onClick}  linkArray={this.props.links}  />
          <p>{this.props.content} </p>
         </div> 
        )
      }
    });


var renderLocationLink = React.createClass({

  render: function(){
    var onClick = this.props.onClick;
    var locationLinks = this.props.linkArray.map(function(link,index){
        return (<a onClick={this.onClick} href={link}>{link}   </a>)
    })

   return ( <div >{locationLinks}</div> )

  }
})

React.renderComponent(feedApp(null),document.body);

您不需要在地图函数中引用"this"来访问本地变量.当您尝试访问onClick变量时删除"this".

var renderLocationLink = React.createClass({

  render: function(){
    var onClick = this.props.onClick;
    var locationLinks = this.props.linkArray.map(function(link,index){
        return (<a onClick={onClick} href={link}>{link}   </a>)
    })

   return ( <div >{locationLinks}</div> )

  }
})
