CSS / jQuery：动态更新的文本出现在右侧而不是圆形进度条内

【中文标题】CSS / jQuery：动态更新的文本出现在右侧而不是圆形进度条内

【英文标题】：CSS / jQuery: Dynamically updated text appears right of instead of inside circular progress bar

【发布时间】：2020-11-01 08:13:30

【问题描述】：

我正在尝试实现一个带有动画的圆形进度条，并从以下资源中发现了该插件。

我下载并包含了该插件，并使用了演示页面中的源代码（html 和 JS），它可以正常工作。 但是，我的问题是 动画文本，即通过 JS 生成的值（从 0 到设定百分比）直接出现在圆圈/图表中，而不是在它们内部（就像在演示中一样）。

我假设我在这里遗漏了一些 CSS，但我不确定需要添加什么来移动圆圈/图表内的值。源代码中的 CSS 有注释说这里不需要。 有人可以帮我吗？

HTML：

<h1 style="margin-top:150px;">jQuery Circle Progress Demos</h1>
<div class="circles">
    <div class="first_circle">
        <span>no <br/> animation</span>
    </div>
    <div class="second_circle">
        <strong>0</strong>  <!-- This should appear inside the circle when being updated via JS -->
        <span>animation <br/> progress</span>
    </div>
    <div class="third_circle">
        <strong>0</strong>  <!-- This should appear inside the circle when being updated via JS -->

JS：

$(document).ready(function()   
    $('.first_circle').circleProgress(
        value: 0.35,
        animation: false,
        fill:  gradient: ['#ff1e41', '#ff5f43'] 
    );
    $('.second_circle').circleProgress(
        value: 0.6
    ).on('circle-animation-progress', function(event, progress) 
        $(this).find('strong').html(parseInt(100 * progress) + '<i>%</i>');
    );
    $('.third_circle').circleProgress(
        value: 0.8,
        fill:  gradient: ['#0681c4', '#07c6c1'] 
    ).on('circle-animation-progress', function(event, progress, stepValue) 
        $(this).find('strong').text(String(stepValue.toFixed(2)).substr(1));
    );
    $('.forth_circle').circleProgress(
        startAngle: -Math.PI / 4 * 3,
        value: .5,
        fill:  color: '#ffa500' 
    );
    $('.fifth_circle').circleProgress(
        value: 1,
        size: 60,
        thickness: 20,
        fill: 
            color: 'lime'
        
    );
);

【参考方案1】：

两个问题。首先，您缺少一些 CSS 以使演示工作。该演示链接到一个 page-styles.css 文件，其中包含一些用于圆圈的 CSS。这带来了第二个问题。即使您只是粘贴 CSS，它也不会“按原样”工作，因为 circle 需要是它自己的类。在您的标记和代码中，您通过在first 和circle 之间添加下划线来组合两个类：

<div class="first_circle">

代替：

<div class="first circle">

因此，为了您的工作方式，您要么需要修改 CSS，要么只需分离类。

这是一个添加了适当 CSS 的示例（我只是从 page-styles.css 文件中复制了相关的 CSS，而不是全部内容）：

$(document).ready(function() 
  $('.first.circle').circleProgress(
    value: 0.35,
    animation: false,
    fill: 
      gradient: ['#ff1e41', '#ff5f43']
    
  );
  $('.second.circle').circleProgress(
    value: 0.6
  ).on('circle-animation-progress', function(event, progress) 
    $(this).find('strong').html(parseInt(100 * progress) + '<i>%</i>');
  );
  $('.third.circle').circleProgress(
    value: 0.8,
    fill: 
      gradient: ['#0681c4', '#07c6c1']
    
  ).on('circle-animation-progress', function(event, progress, stepValue) 
    $(this).find('strong').text(String(stepValue.toFixed(2)).substr(1));
  );
  $('.forth.circle').circleProgress(
    startAngle: -Math.PI / 4 * 3,
    value: .5,
    fill: 
      color: '#ffa500'
    
  );
  $('.fifth.circle').circleProgress(
    value: 1,
    size: 60,
    thickness: 20,
    fill: 
      color: 'lime'
    
  );
);

我选择了这个解决方案，因为这正是我遇到的问题，并且它以这种方式完美运行。

我只是从演示中将它放在一起，我认为你错过了一些东西或删除了一些东西，因为它抛出了错误。
