有没有办法根据 slider 的 position 使标记/图标/文本出现在网站上？

Question

I attempting to make a website which would have a slider that which the websites user could slide to set a specific date.我试图创建一个网站，该网站将具有 slider，网站用户可以滑动该网站以设置特定日期。 Under the slider I am planning to have a map on which markers would appear/move/disappear depending on where the slider is located.在 slider 下，我计划有一个 map，根据 slider 的位置，标记会出现/移动/消失。 So far, with the help of this great community here (RobG specifically), I have a working slider, a map and pretty much everything else except I can't find a way how to make these markers or icons or text appear in the website depending on the position of the slider.到目前为止，在这个伟大的社区（特别是 RobG）的帮助下，我有一个工作 slider、一个 map 和几乎所有其他东西，除了我找不到如何使这些标记或图标或文本出现在网站上的方法取决于 slider 的 position。

For an example of the slider look here: https://www.w3schools.com/howto/tryit.asp?filename=tryhow_css_rangeslider有关 slider 的示例，请查看此处： https://www.w3schools.com/howto/tryit.asp?filename=tryhow_css_rangeslider

<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<style>
.slidecontainer {
      width: 100%;
    }

    .slider {
      -webkit-appearance: none;
      width: 100%;
      height: 25px;
      background: #d3d3d3;
      outline: none;
      opacity: 0.7;
      -webkit-transition: .2s;
      transition: opacity .2s;
    }

    .slider:hover {
      opacity: 1;
    }

    .slider::-webkit-slider-thumb {
      -webkit-appearance: none;
      appearance: none;
      width: 25px;
      height: 25px;
      background: #4CAF50;
      cursor: pointer;
    }

    .slider::-moz-range-thumb {
      width: 25px;
      height: 25px;
      background: #4CAF50;
      cursor: pointer;
    }
    </style>
    </head>
    <body>

    <h1>Custom Range Slider</h1>

    <div class="slidecontainer">
      <p>Default range slider:</p>
      <input type="range" min="1" max="100" value="50">

      <p>Custom range slider:</p>
      <input type="range" min="0" max="1" value="0.5" class="slider" id="myRange" step="0.1">
    </div>

 <script>
        myRange.onchange=function() {
        var fader = document.getElementById('myRange');
        document.getElementById('https://www.mapsofindia.com/worldmap/map-of-world.jpg').style.opacity = fader.value;
        }

    </script>

    </body>
    </html>

Answer 1

You can add the following script to make it work您可以添加以下脚本以使其工作

  <script>
        myRange.onchange=function() {
        var fader = document.getElementById('myRange');
        document.getElementById('pic').style.opacity = fader.value;
        }

    </script>

The 'pic' ID will be the ID of the image. 'pic' ID 将是图像的 ID。

Edit: You will also need to change the value of your slider to range from 0 to 1. Use the following line.编辑：您还需要将 slider 的值更改为从 0 到 1。使用以下行。

<input type="range" min="0" max="1" value="0.5" class="slider" id="myRange" step="0.1">
