Question

我需要一个这样或类似的复选框

关于样式复选框，有很多答案，但是在Bootstrap 4.1.x中都没有，因为我使用错误，或者在此Bootstrap版本中不起作用。

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" rel="stylesheet"/>
<label class="custom-control custom-checkbox">
      <input type="checkbox" class="custom-control-input">
      <span class="custom-control-indicator"></span>
      <span class="custom-control-description">Check this custom checkbox</span>
</label>

这里是如何使用 bootstrap 和 fontawesome 制作自定义复选框

<style>
        .custom-checkbox {
            padding: 0;
        }

            .custom-checkbox .fa-toggle-on,
            .custom-checkbox .fa-toggle-off {
                font-size: 135%;
                /*this icon is relatively small*/
            }

            .custom-checkbox input[type=checkbox] {
                visibility: collapse;
                width: 0px;
                margin-left: -0.25em;
            }

                .custom-checkbox input[type=checkbox] ~ .custom-check-on {
                    display: none;
                }

                .custom-checkbox input[type=checkbox]:checked ~ .custom-check-on {
                    display: inline;
                }

                .custom-checkbox input[type=checkbox]:checked ~ .custom-check-off {
                    display: none;
                }

                .custom-checkbox input[type=checkbox]:disabled ~ * {
                    color: #b6b4b4;
                }

                .custom-checkbox input[type=checkbox].error ~ .custom-check-on,
                .custom-checkbox input[type=checkbox].error ~ .custom-check-off {
                    border: solid 2px red;
                }

            .custom-checkbox i.btn {
                overflow: hidden;
                color: transparent;
                position: relative;
                display: inline-block;
                width: 3em;
                padding: 0;
                font-style: normal;
            }

            .custom-checkbox .btn:after {
                content: "";
                font-style: normal;
                border: 7px solid white;
                position: absolute;
                top: 0;
                bottom: 0;
                border-radius: 5px;
            }

            .custom-checkbox .custom-check-on.btn:after {
                right: -4px;
            }

            .custom-checkbox .custom-check-off.btn:after {
                left: -4px;
            }

            .custom-checkbox .custom-check-on.btn:before {
                content: "On";
                color: white;
                margin-left: -10px;
            }

            .custom-checkbox .custom-check-off.btn:before {
                content: "Off";
                color: #333;
                margin-right: -15px;
            }

            .custom-checkbox input[type=checkbox]:checked ~ .btn.custom-check-on {
                display: inline-block;
            }

Answer 2

更改

 <span class="custom-control-description">Check this custom checkbox</span>

到

<span class="custom-control-label">Check this custom checkbox</span>

您缺少类标签的内容，不应该是描述，而应该是标签。

const checkbox = document.getElementById('checkbox')
checkbox.checked = true

.custom-control-input:checked~.custom-control-label::before {
    color: white !important;
    background-color: green !important;
}

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" rel="stylesheet" />


<label class="custom-control custom-checkbox">
      <input type="checkbox" id="checkbox" class="custom-control-input">
      <span class="custom-control-indicator"></span>
      <span class="custom-control-label">Check this custom checkbox</span>
</label>
