如何使用jQuery制作进度条图表

假设你正在准备某些数据的表格数据。因此，柱状图被用来以图形的方式表示数据，以获得更好的视觉帮助。这些数据可以从一群人的年龄到某一范围，学生在某一科目的分数。

方法：我们将创建HTML进度条，其初始值为10%。我们将把进度条设计成各种颜色和图案。然后我们将为进度条创建JavaScript代码。

实现代码:

   
<!DOCTYPE html>
<html lang="en">
  
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content=
        "width=device-width, initial-scale=1.0">
  
    <style>
        .bar {
            width: 500px;
            height: 80px;
            background-color: aquamarine;
            border-radius: 100px;
            display: flex;
            align-items: center;
        }
  
        .progress {
            width: 467px;
            width: 50px;
            height: 50px;
            background-color: grey;
            border-radius: 100px;
            margin-left: 17px;
        }
  
        .percentage {
            position: absolute;
            margin-left: 30px;
            font-weight: bold;
        }
  
        input {
            margin-bottom: 30px;
        }
    </style>
</head>
  
<body>
    <h3>
        Enter a number between 1 
        and 100 for progress
    </h3>
  
    <input type="number" min="0" max="100">
      
    <div class="bar">
        <div class="progress">
        </div>
        <div class="percentage">0%</div>
    </div>
  
    <script>
        const input = document.querySelector('input');
        const progress = document.querySelector('.progress');
        const percentage = document.querySelector('.percentage');
        console.log(progress)
        let percentComplete = 0;
  
        input.onchange = function () {
            percentComplete = input.value
            console.log(percentComplete);
              
            progress.style.width = 
                ` ${percentComplete / 100 * 417 + 50}px`; percentage.innerHTML = `$ {percentComplete}%`;
        };
    </script>
</body>
  
</html>
