            stroke: none;

    </style>

JS代码
1、引用TweenMax.min.js(附件下载)

2、添加js脚本

var count = 5;
    var circles = [];
    var lines = [];
    var colors = ['#0084c7', '#f2c418', '#000', '#00a24a', '#e01e26'];
    var reverse = [false, false, false, true, true];

    for (var i = 1; i <= count; i++) {
        var circle = document.getElementById("c" + i);
        var circleLength = circle.getTotalLength();
        circle.style.strokeDasharray = circleLength + ' ' + circleLength;
        circle.style.stroke = colors[i - 1];
        circles.push({
            node: circle,
            length: circleLength
        });

        var path = document.getElementById("p" + i);
        var pathLength = path.getTotalLength();
        path.style.strokeDasharray = circleLength + ' ' + pathLength;
        lines.push({
            node: path,
            length: pathLength
        })
    }

    var speed = 2.5;
    var delay = speed - 0.12;
    var delayStep = 0.2;

    animate();
    document.onclick = animate;

    function animate() {
        TweenMax.killAll();

        for (var i = 0; i < count; i++) {
            var path = lines[i].node;
            var stagger = i * delayStep;

            path.style.strokeDashoffset = lines[i].length;
            path.style.stroke = '#fff'; //colors[i];
            path.style.opacity = 0;
            path.style.strokeWidth = Math.random() * 15;
            TweenMax.to(path, speed, {
                delay: stagger,
                stroke: colors[i],

                strokeDashoffset: -lines[i].length,
                ease: Power1.easeIn
            });

            var circle = circles[i].node;
            circle.style.strokeDashoffset = reverse[i] ? -circles[i].length : circles[i].length
            TweenMax.to(circle, speed / 4, {
                delay: stagger + delay,
                strokeDashoffset: 0,
                ease: Power2.easeOut
            });
        }
    }
