Question

我＆＃39;我试图用SVG制作一个循环时间轴。我正在使用整页js 所以我做了一个蓝线在圆圈上滚动，但现在我想要我的锚点数字阵列也出现但我找不到解决方案，我希望我的锚点出现并停留在我向下滚动（如时间轴）并来向上滚动时返回灰色

＆＃13;

$(document).ready(function() {
			$('#fullpage').fullpage({
				anchors: ['firstPage', 'secondPage', '3rdPage', '4thPage', 'lastPage'],
				menu: '#menu',
				scrollingSpeed: 1000,		
                onLeave: function(index, nextIndex, direction){
                  $('#bluecircle').css('stroke-dashoffset', (1510/4)*(4-(nextIndex-1))); 
				   }
	
				   });
				});

我的代码：

Answer 1

只需添加一个数组，其中包含每个圈子的ID，并在查找事件返回的onleave后更改object事件中的css：

var smallCircles= ['top','right','bottom','left','top'];
...
onLeave: function(...

    if(direction=='up'){
         $('#smallblue'+smallCircles[nextIndex]).css('stroke-dashoffset', '40');
         }
    $('#smallblue'+smallCircles[nextIndex-1]).css('stroke-dashoffset', '0');

var smallCircles= ['top','right','bottom','left','top'];
$(document).ready(function() {
			$('#fullpage').fullpage({
				anchors: ['firstPage', 'secondPage', '3rdPage', '4thPage', 'lastPage'],
				menu: '#menu',
				scrollingSpeed: 1000,		
                onLeave: function(index, nextIndex, direction){
                  $('#bluecircle').css('stroke-dashoffset', (1510/4)*(4-(nextIndex-1))); 
                  if(direction=='up'){$('#smallblue'+smallCircles[nextIndex]).css('stroke-dashoffset', '40');}
                  $('#smallblue'+smallCircles[nextIndex-1]).css('stroke-dashoffset', '0');
				   }
	
				   });
				});
