html - CSS 进度圈

Question

我已经在这个网站上搜索过进度条，但我能找到的进度条显示的动画圈达到了 100%。

我希望它停止在某些百分比，如下面的屏幕截图所示。有什么办法可以只使用 CSS 来做到这一点吗？

Answer 1

我只使用 CSS创建了一个小提琴。

.wrapper {
  width: 100px; /* Set the size of the progress bar */
  height: 100px;
  position: absolute; /* Enable clipping */
  clip: rect(0px, 100px, 100px, 50px); /* Hide half of the progress bar */
}
/* Set the sizes of the elements that make up the progress bar */
.circle {
  width: 80px;
  height: 80px;
  border: 10px solid green;
  border-radius: 50px;
  position: absolute;
  clip: rect(0px, 50px, 100px, 0px);
}
/* Using the data attributes for the animation selectors. */
/* Base settings for all animated elements */
div[data-anim~=base] {
  -webkit-animation-iteration-count: 1;  /* Only run once */
  -webkit-animation-fill-mode: forwards; /* Hold the last keyframe */
  -webkit-animation-timing-function:linear; /* Linear animation */
}

.wrapper[data-anim~=wrapper] {
  -webkit-animation-duration: 0.01s; /* Complete keyframes asap */
  -webkit-animation-delay: 3s; /* Wait half of the animation */
  -webkit-animation-name: close-wrapper; /* Keyframes name */
}

.circle[data-anim~=left] {
  -webkit-animation-duration: 6s; /* Full animation time */
  -webkit-animation-name: left-spin;
}

.circle[data-anim~=right] {
  -webkit-animation-duration: 3s; /* Half animation time */
  -webkit-animation-name: right-spin;
}
/* Rotate the right side of the progress bar from 0 to 180 degrees */
@-webkit-keyframes right-spin {
  from {
    -webkit-transform: rotate(0deg);
  }
  to {
    -webkit-transform: rotate(180deg);
  }
}
/* Rotate the left side of the progress bar from 0 to 360 degrees */
@-webkit-keyframes left-spin {
  from {
    -webkit-transform: rotate(0deg);
  }
  to {
    -webkit-transform: rotate(360deg);
  }
}
/* Set the wrapper clip to auto, effectively removing the clip */
@-webkit-keyframes close-wrapper {
  to {
    clip: rect(auto, auto, auto, auto);
  }
}

<div class="wrapper" data-anim="base wrapper">
  <div class="circle" data-anim="base left"></div>
  <div class="circle" data-anim="base right"></div>
</div>

</div>

或者这个带有 HTML5、CSS3 和 JavaScript 的漂亮圆形进度条。

Answer 2

那个怎么样？

HTML

<div class="chart" id="graph" data-percent="88"></div>

Javascript

var el = document.getElementById('graph'); // get canvas

var options = {
    percent:  el.getAttribute('data-percent') || 25,
    size: el.getAttribute('data-size') || 220,
    lineWidth: el.getAttribute('data-line') || 15,
    rotate: el.getAttribute('data-rotate') || 0
}

var canvas = document.createElement('canvas');
var span = document.createElement('span');
span.textContent = options.percent + '%';

if (typeof(G_vmlCanvasManager) !== 'undefined') {
    G_vmlCanvasManager.initElement(canvas);
}

var ctx = canvas.getContext('2d');
canvas.width = canvas.height = options.size;

el.appendChild(span);
el.appendChild(canvas);

ctx.translate(options.size / 2, options.size / 2); // change center
ctx.rotate((-1 / 2 + options.rotate / 180) * Math.PI); // rotate -90 deg

//imd = ctx.getImageData(0, 0, 240, 240);
var radius = (options.size - options.lineWidth) / 2;

var drawCircle = function(color, lineWidth, percent) {
        percent = Math.min(Math.max(0, percent || 1), 1);
        ctx.beginPath();
        ctx.arc(0, 0, radius, 0, Math.PI * 2 * percent, false);
        ctx.strokeStyle = color;
        ctx.lineCap = 'round'; // butt, round or square
        ctx.lineWidth = lineWidth
        ctx.stroke();
};

drawCircle('#efefef', options.lineWidth, 100 / 100);
drawCircle('#555555', options.lineWidth, options.percent / 100);

和 CSS

div {
    position:relative;
    margin:80px;
    width:220px; height:220px;
}
canvas {
    display: block;
    position:absolute;
    top:0;
    left:0;
}
span {
    color:#555;
    display:block;
    line-height:220px;
    text-align:center;
    width:220px;
    font-family:sans-serif;
    font-size:40px;
    font-weight:100;
    margin-left:5px;
}

Answer 3

另一个基于纯 css 的解决方案，它基于两个裁剪的圆形元素，我旋转它们以达到正确的角度：

http://jsfiddle.net/maayan/byT76/

这是启用它的基本 css：

.clip1 {
    position:absolute;
    top:0;left:0;
    width:200px;
    height:200px;
    clip:rect(0px,200px,200px,100px);
}
.slice1 {
    position:absolute;
    width:200px;
    height:200px;
    clip:rect(0px,100px,200px,0px);
    -moz-border-radius:100px;
    -webkit-border-radius:100px; 
    border-radius:100px;
    background-color:#f7e5e1;
    border-color:#f7e5e1;
    -moz-transform:rotate(0);
    -webkit-transform:rotate(0);
    -o-transform:rotate(0);
    transform:rotate(0);
}

.clip2 
{
    position:absolute;
    top:0;left:0;
    width:200px;
    height:200px;
    clip:rect(0,100px,200px,0px);
}

.slice2
{
    position:absolute;
    width:200px;
    height:200px;
    clip:rect(0px,200px,200px,100px);
    -moz-border-radius:100px;
    -webkit-border-radius:100px; 
    border-radius:100px;
    background-color:#f7e5e1;
    border-color:#f7e5e1;
    -moz-transform:rotate(0);
    -webkit-transform:rotate(0);
    -o-transform:rotate(0);
    transform:rotate(0);
}

并且js根据需要旋转它。

很容易理解。。

希望它有帮助，玛雅人

Answer 4

看一下这个 ：）

我使用conic-gradient制作了这个。

background: conic-gradient(
      SomeColor1 80%,
      SomeColor2 80%
    );

您可以使用圆锥梯度创建饼图。

div {
  background: conic-gradient(
     red 36deg, orange 36deg 170deg, yellow 170deg);
  border-radius: 50%
}

我只为饼图选择了两种颜色。

  background: conic-gradient(
          rgb(3, 133, 255) 80%,
          rgb(242, 242, 242) 80%
        );

然后在饼图顶部放置一个 div 使其看起来像一个圆形进度指示器。然后使用 HTML DOM innerHTML 选项设置进度。

然后你可以使用 incrementProgress() 和 decrementProgress() 函数来动态改变进度。

按照我的完整示例获得一些想法:)

您可以使用它制作上传/下载进度指示器、仪表板图表等。

      document
        .getElementById("decbtn")
        .addEventListener("click", decrementProgress);

      function incrementProgress() {
        if (progress != 100) {
          progress = progress + 10;
          console.log(progress);
          setProgress();
        }
      }

      function decrementProgress() {
        if (progress != 0) {
          progress = progress - 10;
          console.log(progress);
          setProgress();
        }
      }

      function setProgress() {
        document.getElementById("progress-spinner").style.background =
          "conic-gradient(rgb(3, 133, 255) " +
          progress +
          "%,rgb(242, 242, 242) " +
          progress +
          "%)";

        document.getElementById("middle-circle").innerHTML =
          progress.toString() + "%";
      }

      window.onload = function () {

Answer 5

用于径向进度条的灵活 SVG 解决方案（仅限 CSS）：计算（通过 calc）SVG 内圆的边框长度的解决方案。

示例中的进度圈覆盖在元素上，并且可能是透明的。

jQuery(function($){
 setTimeout(() => $('#element1 [data-role="radial-progress"]').css('--progress-percent', '100'), 1000);
 $('#element2 [data-role="radial-progress"]').css('--progress-percent', '80');
 $('#element3 [data-role="radial-progress"]').css('--progress-percent', '100');
 
 let progress4 = 0;
 let progress4incrementor = setInterval(() => {
  progress4++;
  $('#element4 .value').html(progress4 + '%');
  $('#element4 [data-role="radial-progress"]').css('--progress-percent', progress4.toString());
  if (progress4 >= 100) clearInterval(progress4incrementor);
 }, 100);
});

.element
{
  position: relative;
}
[data-role="radial-progress"]
{
    position: absolute;
    left: 0;
    top: 0;
    right: 0;
    bottom: 0;
    z-index: 1;
    --progress-percent: 0;
  --progress-color: #CC000077;
  --progress-bar-width: 100%;
}
[data-role="radial-progress"] > circle
{
    stroke-width: var(--progress-bar-width);
    stroke-dasharray: calc(100% * 3.141592);
    stroke-dashoffset: calc(100% * (100 - var(--progress-percent))/100 * 3.141592);
    stroke: var(--progress-color);
}



/*Just for animate --data-percent */

与新的不同的想法@property。见支持表

@property --a {

我看到了Alvaro Montoro的一个更有力的例子。请务必检查一下。
