如何使用jQuery Mobile创建一个带有步骤属性的滑块

使用jQuery Mobile创建一个带有步骤属性的滑块可以使用官方提供的“Slider with Steps”功能。下面是创建步骤滑块的完整攻略步骤：

加载jQuery和jQuery Mobile

在HTML文件中，需要在head标签内加载jQuery和jQuery Mobile库，代码如下：

<head>
  <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
  <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.css">
  <script src="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.js"></script>
</head>

定义滑块

在body标签内，需要定义一个滑块组件，代码如下：

<div data-role="rangeslider">
  <label for="slider-1">Slider with step:</label>
  <input type="range" name="slider-1" id="slider-1" min="0" max="100" step="10" value="20">
  <label for="slider-2">Slider with step:</label>
  <input type="range" name="slider-2" id="slider-2" min="0" max="100" step="10" value="80">
</div>

定义步骤

在滑块组件内，需要定义每一个步骤，代码如下：

<div class="ui-field-contain">
  <fieldset data-role="controlgroup" data-type="horizontal">
    <legend>Steps</legend>
    <label for="step1">Step 1</label>
    <input type="radio" name="slider-step" id="step1" value="0" checked>
    <label for="step2">Step 2</label>
    <input type="radio" name="slider-step" id="step2" value="10">
    <label for="step3">Step 3</label>
    <input type="radio" name="slider-step" id="step3" value="20">
    <label for="step4">Step 4</label>
    <input type="radio" name="slider-step" id="step4" value="30">
    <label for="step5">Step 5</label>
    <input type="radio" name="slider-step" id="step5" value="40">
    <label for="step6">Step 6</label>
    <input type="radio" name="slider-step" id="step6" value="50">
    <label for="step7">Step 7</label>
    <input type="radio" name="slider-step" id="step7" value="60">
    <label for="step8">Step 8</label>
    <input type="radio" name="slider-step" id="step8" value="70">
    <label for="step9">Step 9</label>
    <input type="radio" name="slider-step" id="step9" value="80">
    <label for="step10">Step 10</label>
    <input type="radio" name="slider-step" id="step10" value="90">
  </fieldset>
</div>

初始化Slider with Steps

在定义好滑块和步骤后，需要对滑块进行初始化。代码如下：

<script>
  $(function() {
    $( "#slider-1" ).on( "slidestop", function( event, ui ) {
      var value = $( "#slider-1" ).val();
      $( 'input[name="slider-step"][value="'+value+'"]' ).prop('checked',true).checkboxradio('refresh');
    });
    $( 'input[name="slider-step"]' ).on( "click", function() {
      var value = $( this ).val();
      $( "#slider-1" ).val( value ).slider( "refresh" );
    });
  });
</script>

示例说明

下面是两个使用步骤滑块的示例说明：

示例一：

<div data-role="rangeslider">
  <label for="slider-1">Slider with step:</label>
  <input type="range" name="slider-1" id="slider-1" min="0" max="100" step="10" value="50">
  <label for="slider-2">Slider with step:</label>
  <input type="range" name="slider-2" id="slider-2" min="0" max="100" step="10" value="60">
</div>
<div class="ui-field-contain">
  <fieldset data-role="controlgroup" data-type="horizontal">
    <legend>Steps</legend>
    <label for="step1">Step 1</label>
    <input type="radio" name="slider-step" id="step1" value="0">
    <label for="step2">Step 2</label>
    <input type="radio" name="slider-step" id="step2" value="10">
    <label for="step3">Step 3</label>
    <input type="radio" name="slider-step" id="step3" value="20">
    <label for="step4">Step 4</label>
    <input type="radio" name="slider-step" id="step4" value="30">
    <label for="step5">Step 5</label>
    <input type="radio" name="slider-step" id="step5" value="40">
    <label for="step6">Step 6</label>
    <input type="radio" name="slider-step" id="step6" value="50">
    <label for="step7">Step 7</label>
    <input type="radio" name="slider-step" id="step7" value="60">
    <label for="step8">Step 8</label>
    <input type="radio" name="slider-step" id="step8" value="70">
    <label for="step9">Step 9</label>
    <input type="radio" name="slider-step" id="step9" value="80">
    <label for="step10">Step 10</label>
    <input type="radio" name="slider-step" id="step10" value="90">
  </fieldset>
</div>
<script>
  $(function() {
    $( "#slider-1" ).on( "slidestop", function( event, ui ) {
      var value = $( "#slider-1" ).val();
      $( 'input[name="slider-step"][value="'+value+'"]' ).prop('checked',true).checkboxradio('refresh');
    });
    $( 'input[name="slider-step"]' ).on( "click", function() {

    <input type="radio" name="slider-step" id="step1" value="0">
    <label for="step2">第二步</label>
    <input type="radio" name="slider-step" id="step2" value="5">
    <label for="step3">第三步</label>

    <label for="step9">第九步</label>
    <input type="radio" name="slider-step" id="step9" value="40">
    <label for="step10">第十步</label>
    <input type="radio" name="slider-step" id="step10" value="45">

</div>
<script>
  $(function() {
    $( "#slider-1" ).on( "slidestop", function( event, ui ) {
      var value = $( "#slider-1" ).val();
      $( 'input[name="slider-step"][value="'+value+'"]' ).prop('checked',true).checkboxradio('refresh');
    });
    $( 'input[name="slider-step"]' ).on( "click", function() {
      var value = $( this ).val();
      $( "#slider-1" ).val( value ).slider( "refresh" );
