我试图将多个滑块范围输入添加到我的网页，并且我希望当我使用滑块时其同级输入的值发生变化。但是我发现只有第一个滑块有效，而其他滑块无效
<div class="form-group my-3 d-flex flex-column">
<div class="d-flex justify-content-between align-items-center simulateur mb-3">
<label for="formGroupExampleInput" class="important">Revenus nets/mois* <i class="fas fa-info-circle"></i></label>
<input type="text" id="revenue" class="form-control" placeholder="" value="0">

<input id="RVN" type="range" value="0" min="0" max="7000" step="100"/>

这就是我的js函数，我对所有函数都使用相同的方式，但只有第一个有效吗？
var i= document.getElementById('RVN');
var o = document.getElementById('revenue');
o.value = i.value;
i.addEventListener('input', function(){
o.value = i.value;
}, false);
var p= document.getElementById('pret');
var vp = document.getElementById('val_pret');
vp.value = p.value;
p.addEventListener('input', function(){
vp.value = p.value;
}, false);
var m= document.getElementById('mensualite');
var vm = document.getElementById('val_mensualite');
vm.value = m.value;
m.addEventListener('input', function(){
vm.value = m.value;
}, false);
var d= document.getElementById('duree');
var vd = document.getElementById('val_duree');
vd.value = d.value;
d.addEventListener('input', function(){
vd.value = d.value;
}, false);
您正在调用输入文本的侦听器
var p= document.getElementById('pret');//input-text
var vp = document.getElementById('val_pret');//input-range
vp.value = p.value;
p.addEventListener('input', function(){ //here is your error
vp.value = p.value;
}, false);
您应该为输入范围调用列表器，这是修改后的代码
var i= document.getElementById('RVN');
var o = document.getElementById('revenue');
o.value = i.value;
i.addEventListener('input', function(){
o.value = i.value;
}, false);
var p= document.getElementById('val_pret');// input-range
var vp = document.getElementById('pret');// input-text
vp.value = p.value;
p.addEventListener('input', function(){//solution
vp.value = p.value;
}, false);
var m= document.getElementById('val_mensualite');
var vm = document.getElementById('mensualite');
vm.value = m.value;
m.addEventListener('input', function(){
vm.value = m.value;
}, false);
