javascript - JavaScript 中的颜色 Storm 文本效果

Question

有人可以指导我使用 JavaScript 文本动画来实现色彩 Storm 效果吗？我没有完美的示例/视频可以分享以增加清晰度。但是，以下 URL 与我在 here 中找到的内容很接近。 .

实际的要求是有一个更像 Storm 的效果，即当颜色流入时垂直随机化。并且沿着字符的高度不对称地分布颜色。让人感觉好像有一场色彩 Storm 正在穿过。

任何指示都值得赞赏。

代码片段

// add animation-delay properties to span elements

var animTime = 6, // time for the animation in seconds
    hueChange = 3, // the hue change from one span element to the next
    prefixes = ["", "-webkit-", "-moz-", "-o-"],
    numPrefixes = prefixes.length;

$('.unicorn').find('span').each(function (i) {
    for (var j = 0; j < numPrefixes; j++) {
        $(this).css(prefixes[j] + 'animation-delay', (animTime * ((i * hueChange) % 360) / 360) - animTime + 's');
    }
});

// needed to avoid Chrome bug:
$('.unicorn').one('mouseover',function(){
    $(this).addClass('animate');
});

.unicorn.animate span {
    -webkit-animation: colorRotate 6s linear 0s infinite;

Answer 1

here现在很顺利

var $c = $('.clip');
var posX = 0;
var posY = 0;
var timeout = Math.random()*1000;

function flow(){
  console.log([$c,posX,posY]);
  posX+=500;
  posY+=500;
  timeout = Math.random()*1000;
  $c.css('-webkit-transition', (timeout/1000)+'s linear');
  $c.css('background-position',posX+'px '+posY+'px');
  setTimeout(flow,timeout)
}
flow();

.clip {
  font-size: 260px;
  font-weight: bold;
  background: repeating-linear-gradient(-45deg, #ff0000 0px, #00ff00 235.7px, #0000ff 471.4px, #ff0000 707.1px);
  -webkit-background-clip: text;
  -webkit-text-fill-color: transparent;
  width: 1000px;
  height: 1000px;
}

.clip.d45 {
  background: repeating-linear-gradient(-45deg, #ff0000 0px, #00ff00 235.7px, #0000ff 471.4px, #ff0000 707.1px);
  -webkit-background-clip: text;
  -webkit-text-fill-color: transparent;
}
