Question

同样，我不擅长编码（我没有经验）。

但是，在这个例子中，我想获得一个Toggle Switches列表的状态。

我设法制作了开关列表。我怎样才能了解它们的状态。

更准确地说，我需要以逗号分隔的Checked项目列表，如Button 1，Button 2，Button 5（当选中Button 1，Button 2和Button 5时）。

<!DOCTYPE html>
<html>
<head>
<style>
.switch {
position: relative;
display: inline-block;
width: 60px;
height: 34px;
}

.switch input {display:none;}

.slider {
position: absolute;
cursor: pointer;
top: 0;
left: 0;
right: 0;
bottom: 0;
background-color: #ccc;
-webkit-transition: .4s;
transition: .4s;
}

.slider:before {
position: absolute;
content: "";
height: 26px;
width: 26px;
left: 4px;
bottom: 4px;
background-color: white;
-webkit-transition: .4s;
transition: .4s;
}

input:checked + .slider {
background-color: #2196F3;
}

input:focus + .slider {
box-shadow: 0 0 1px #2196F3;
}

input:checked + .slider:before {
-webkit-transform: translateX(26px);
-ms-transform: translateX(26px);
transform: translateX(26px);
}

/* Rounded sliders */
.slider.round {
border-radius: 34px;
}

.slider.round:before {
border-radius: 50%;
}
</style>
</head>
<body>

<h2>

<table style="width:100%">

  <tr>
    <td>Switch 1</td>
    <td><label class="switch">
<id name="Switch 1">
<input type="checkbox" unchecked>
<span class="slider round"></span>

  </tr>

  <tr>

    <td><label class="switch">

  </tr>

  <tr>

    <td><label class="switch">

    <td>Switch 5</td>
    <td><label class="switch">

<span class="slider round"></span>
</label></td> 
  </tr>


</table>

<br><br>
<button type="button" onclick="alert('Hello world!')">Cancel</button>

Try this:
Change in html code

       <table style="width:100%">

      <tr>
        <td>Switch 1</td>
        <td><label class="switch">
    <id name="Switch 1">
    <input type="checkbox" class="testClass" value="1" unchecked>
    <span class="slider round"></span>
    </label></td> 
      </tr>

      <tr>
        <td>Switch 2</td>
        <td><label class="switch">
    <id name="Switch 2">
    <input type="checkbox" class="testClass" value="2" unchecked>
    <span class="slider round"></span>
    </label></td> 
      </tr>

      <tr>
       <td>Switch 3</td>
        <td><label class="switch">
    <id name="Switch 3">
    <input type="checkbox" class="testClass" value="3" unchecked>
    <span class="slider round"></span>
    </label></td> 
      </tr>

      <tr>
        <td>Switch 4</td>
        <td><label class="switch">
    <id name="Switch 4">
    <input type="checkbox" class="testClass" value="4" unchecked>
    <span class="slider round"></span>
    </label></td> 
      </tr>

      <tr>
        <td>Switch 5</td>
        <td><label class="switch">
    <id name="Switch 5">
    <input type="checkbox" class="testClass" value="5" unchecked>
    <span class="slider round"></span>
    </label></td> 
      </tr>


    </table>

   Jquery Code:

   var checkedVals = $('.testClass:checkbox:checked').map(function() {
      return this.value;
   }).get();
   alert(checkedVals.join(","));

我已经使用过Jquery并且在切换时你将获得警报中的值。这是你问的吗？

Answer 3

您可以在JavaScript中执行此操作。

首先，我建议您将id（即"Switch 1"，"Switch 2"，"Switch 3"等）分配给每个输入，以便您可以登录它们。

然后，您可以为按钮指定一个功能，以显示已检查的输入。

<强> HTML

<button type="button" onclick="showCheckedInputs()">Show Checked Switches</button>

<强>的JavaScript

function showCheckedInputs() {
  var checkboxes = document.querySelectorAll('input[type="checkbox"]');
  var checkedInputs = [];
  for (var i = 0; i < checkboxes.length; i++) {
    if(checkboxes[i].checked) {
      checkedInputs.push(checkboxes[i].id)
    }
  }
  // log results to the console
  console.log(checkedInputs);
  // render results to the DOM
  document.getElementById('result').innerHTML = checkedInputs.join(', ');
}

这是Demo

P.S。你的开关看起来很酷！
