Question

我的html视频地址换了，但还是原来的视频。

    var source = document.querySelector('source');//要改的地方
    var dian = document.querySelector('.dian');//要点击的地方
    for (var i = 0;i< 4;i++){
        var index = i+1;
        dian.children[i].setAttribute('index',index);
        dian.children[i].addEventListener('click',function(){    
            source.src = 'images/vid-'+this.getAttribute('index')+'.mp4'    
        })                    
    }

      <video width="100%" loop  muted autoplay>
            <source src="images/vid-4.mp4" type="video/mp4"></source></video>
