javascript - 更改另一个滑块时更新材质滑块 UI

Question

我的输入有问题。两个输入均已连接。当您单击第一个时，第二个输入将移动但 css 不会更新。

var $ra1 = $('#range1');
var $ra2 = $('#range2');

$ra1.on('input', function() {
    $ra2.val(this.max - this.value);
});
$ra2.on('input', function() {
    $ra1.val(this.max - this.value);
});

<script defer src="https://code.getmdl.io/1.3.0/material.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Range 1
<input type="range" min="0" max="400" value="0" class="mdl-slider mdl-js-slider " id="range1">

Range 2
<input type="range" min="0" max="400" value="400" class="mdl-slider mdl-js-slider" id="range2">

编辑： 我找到了 IE11 的解决方法

var $ra1 = $('#range1');
var $ra2 = $('#range2');
if (navigator.appName == 'Microsoft Internet Explorer' ||  !!(navigator.userAgent.match(/Trident/) || navigator.userAgent.match(/rv:11/)) || (typeof $.browser !== "undefined" && $.browser.msie == 1)){
    $ra1.change(function(){
        $ra2.get(0).MaterialSlider.change(this.max - this.value);
    });
    $ra2.change(function(){
        $ra1.get(0).MaterialSlider.change(this.max - this.value);
    });
 }else{
    $ra1.on('input', function() {
        $ra2.get(0).MaterialSlider.change(this.max - this.value);
    });
    $ra2.on('input', function() {
        $ra1.get(0).MaterialSlider.change(this.max - this.value);
    });
 }

为此，您需要通过 Material 库而不是 jQuery 设置值，以便它更新 UI。为此，请在 DOM 元素change的属性上使用该函数，如下所示：MaterialSlider

var $ra1 = $('#range1');
var $ra2 = $('#range2');

$ra1.on('input', function() {
  $ra2.get(0).MaterialSlider.change(this.max - this.value);
});

$ra2.on('input', function() {
  $ra1.get(0).MaterialSlider.change(this.max - this.value);
});

<link rel="stylesheet" href="https://fonts.googleapis.com/icon?family=Material+Icons">
<link rel="stylesheet" href="https://code.getmdl.io/1.3.0/material.indigo-pink.min.css">
<script defer src="https://code.getmdl.io/1.3.0/material.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Range 1
<input type="range" min="0" max="400" value="0" class="mdl-slider mdl-js-slider " id="range1"> Range 2
<input type="range" min="0" max="400" value="400" class="mdl-slider mdl-js-slider" id="range2">
