根据范围滑块的拇指悬停来样式化元素

时间：2020-09-18 05:44:09

标签： html css hover range

我正在尝试为范围滑块的拇指以及始终位于其上方的一些文本创建悬停效果。

我有以下代码，但我不确定应该使用哪组CSS选择器来创建正确的悬停。我尝试过<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-3-typeahead/4.0.2/bootstrap3-typeahead.min.js"></script> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" /> <div class="container"> <div id="the-basics"> <input class="typeahead" type="text" placeholder="States of USA" autocomplete="off"> </div> </div>，但即使更改DOM中元素的顺序，也似乎没有用。

有问题的代码是：

+ ~

文字的颜色应变为绿色。

当您在滑块上的任何位置时，都会更改内容的解决方法。那就是我能找到的最好的。 kiiinda之所以有意义，是因为无论如何您都可以拖动滑块或单击范围。也许对您有用？

$( window ).on( "load", function() { 
    sliderValues();

$( window ).resize(function() {
   sliderValues();

let mouseDown;
$(document).mousedown(function() {
    mouseDown = true;
}).mouseup(function() {
    mouseDown = false;  
});


let stepChangeThreshold = 3000;


$('#range').on('mousemove',function(e){
    if (!mouseDown) return;
    
    this.previousClientX = this.previousClientX || e.clientX;
    let stepChangeThresholdPositionX = this.getBoundingClientRect().x+($('#range').width()*stepChangeThreshold/5500);
    
    
    if (this.value == stepChangeThreshold){
        if ((this.previousClientX > e.clientX) && (e.clientX < stepChangeThresholdPositionX)){
            this.step = 250;
        } else {
            this.step = 500;
        }

感谢大家的所有建议，我使用纯CSS进行了研究。 问题是您不能真正使用:webkit-slider-thumb作为样式CSS元素的选择器。

要解决此问题，我使用了#range作为选择器。如果我在范围滑块上的任意位置鼠标，都会触发效果触发。因此，我在范围上设置了pointer-events: none;，在范围拇指上设置了pointer-events: auto;。

我需要重新排列HTML中的元素并在CSS中修复一些样式

$( window ).resize(function() {
   sliderValues();

let mouseDown;

    if (!mouseDown) return;
    
    this.previousClientX = this.previousClientX || e.clientX;
    let stepChangeThresholdPositionX = this.getBoundingClientRect().x+($('#range').width()*stepChangeThreshold/5500);
    
    
    if (this.value == stepChangeThreshold){
        if ((this.previousClientX > e.clientX) && (e.clientX < stepChangeThresholdPositionX)){
            this.step = 250;
        } else {
            this.step = 500;
        }
