Javascript，相同的代碼，不同的按鈕錯誤

Question

發生了一些奇怪的事情，我有一個函數應該以相同的方式處理所有的按鈕，但它沒有。我找不到錯誤。 只有第三個按鈕正常工作。輸入範圍div移動並將其置於另一側，以便您可以切換它。

我想這是與左動畫或CSS變量的一個問題。

$(document).ready(function(){ 
 
    $('#reak00').change(saveSettings); 
 
    $('#rebk00').change(saveSettings); 
 
    $('#reck00').change(saveSettings);  
 
    loadSettings(); 
 
    }); 
 
    function loadSettings() { 
 
    $('#reak00').val(localStorage.reak00); 
 
    $('#rebk00').val(localStorage.rebk00); 
 
    $('#reck00').val(localStorage.reck00);

    localStorage.rebk00 = $('#rebk00').val(); 
 
    localStorage.reck00 = $('#reck00').val();  
 
    }

        'left': (posizione *100/200)

Answer 1

.fkbtn01, .fkbtn02, .fkbtn03 input { 
.fkbtn01, .fkbtn02, .fkbtn03 input::-webkit-slider-thumb { 

當你這樣做的CSS選擇這樣的，在最後的輸入部分並不適用於它之前的所有字段。只有前一個。因爲這些規則隻影響與fkbtn03相關的輸入。

例

.fkbtn01 input, .fkbtn02 input, .fkbtn03 input { 
.fkbtn01 input::-webkit-slider-thumb, .fkbtn02 input::-webkit-slider-thumb, .fkbtn03 input::-webkit-slider-thumb {
