了解如何使用 CSS 和 JavaScript 创建自定义范围滑块。
<div class="slidecontainer">
<input type="range" min="1" max="100" value="50" class="slider" id="myRange">
</div>
.slidecontainer {
width: 100%; /* Width of the outside container */
}
/* The slider itself */
.slider {
-webkit-appearance: none; /* Override default CSS styles */
appearance: none;
width: 100%; /* Full-width */
height: 25px; /* Specified height */
background: #d3d3d3; /* Grey background */
outline: none; /* Remove outline */
opacity: 0.7; /* Set transparency (for mouse-over effects on hover) */
-webkit-transition: .2s; /* 0.2 seconds transition on hover */
transition: opacity .2s;
}
/* Mouse-over effects */
.slider:hover {
opacity: 1; /* Fully shown on mouse-over */
}
/* The
slider handle (use -webkit- (Chrome, Opera, Safari, Edge) and -moz- (Firefox) to override default look) */
.slider::-webkit-slider-thumb {
-webkit-appearance: none; /* Override default look */
appearance: none;
width: 25px; /* Set a specific slider handle width */
height: 25px; /* Slider handle height */
background: #04AA6D; /* Green background */
cursor: pointer; /* Cursor on hover */
}
.slider::-moz-range-thumb {
width: 25px; /* Set a specific slider handle width */
height: 25px; /* Slider handle height */
background: #04AA6D; /* Green background */
cursor: pointer; /* Cursor on hover */
}

使用 JavaScript 创建动态范围滑块来显示当前值:
var slider = document.getElementById("myRange");
var output = document.getElementById("demo");
output.innerHTML = slider.value; // Display the default slider value
// Update the current slider value (each time you drag the slider handle)
slider.oninput = function() {
output.innerHTML = this.value;
}

要创建圆形滑块手柄,请使用border-radius
属性。提示:如果您想要不等的高度(本例中为 15px 与 25px),请将滑块的高度设置为与滑块拇指不同的值:
.slider {
-webkit-appearance: none;
width: 100%;
height: 15px;
border-radius: 5px;
background: #d3d3d3;
outline: none;
opacity: 0.7;
-webkit-transition: .2s;
transition: opacity .2s;
}
.slider::-webkit-slider-thumb {
-webkit-appearance: none;
appearance: none;
width: 25px;
height: 25px;
border-radius: 50%;
background: #04AA6D;
cursor: pointer;
}
.slider::-moz-range-thumb {
width: 25px;
height: 25px;
border-radius: 50%;
background: #04AA6D;
cursor: pointer;
}

要创建滑块手柄图标/图片,请使用background
属性并插入图片 url:
.slider::-webkit-slider-thumb {
-webkit-appearance: none;
appearance: none;
width: 23px;
height: 24px;
border: 0;
background: url('contrasticon.png');
cursor: pointer;
}
.slider::-moz-range-thumb {
width: 23px;
height: 25px;
border: 0;
background: url('contrasticon.png');
cursor: pointer;
}
