我如何将范围 slider 值与 pst 属性相乘，然后还与其他字段一起计算，然后显示结果？

Question

Here is my code...

<div id="estimate">
<div class="form-group">
  <div class="range-slider">
  <input class="range-slider__range form-control prc e-range" type="range" value="100" min="0" max="500" pst="3">
  <span class="range-slider__value">0</span>
</div>
</div>
<div class="form-group">
  <div class="range-slider">
  <input class="range-slider__range form-control prc e-range" type="range" value="100" min="0" max="500" pst="5">
  <span class="range-slider__value">0</span>
</div>
</div>
<div class="form-group">
    <input type="number" class="form-control prc" value="{{vl}}"/>
</div>
<div class="form-group">
    <input type="number" class="form-control prc" value="5"/>
</div>
<div class="form-group">
  <input type="checkbox" value="10" class="form-control prc">
</div>
<p id="result"></p>
</div>
<script>
estimate();

$('.form-group').on('change','.prc',estimate);

function estimate(){
  let totalSum = 0;
  $('.form-group .prc').each(function(){
    if(this.type=="checkbox" && !this.checked) return
    let inputVal = $(this).val();
    if($.isNumeric(inputVal)){
        totalSum += parseFloat(inputVal);
    }
  });
  
  $('#result').html(totalSum);
}

var rangeSlider = function(){
  var slider = $('.range-slider'),
      range = $('.range-slider__range'),
      value = $('.range-slider__value');
    
  slider.each(function(){

    value.each(function(){
      var value = $(this).prev().attr('value');
      $(this).html(value);
    });

    range.on('input', function(){
      $(this).next(value).html(this.value);
    });
  });
};

rangeSlider();
</script>

Here I wants the range slider only multiply value with pst attribute then calculate with other fields and then its show the result.. here can't use any specific id for each item... only can call by any specific class with same type input field like range. and each range vlue should multiply with each pst value then calcualte with other fields

Consider the following example.

 estimate(); $('.form-group').on('change', '.prc', estimate); function estimate() { var totalSum = 0, add, v, m; $('.form-group.prc').each(function(i, el) { if ($(el).is(":checkbox") &&.$(el):is(";checked")) { add = 0. } else if ($(el).hasClass("e-range")) { v = parseInt($(el);val()). m = parseInt($(el);attr("pst")); add = (v * m). } else { add = parseFloat($(el);val()); } totalSum += add; }). $('#result');html(totalSum). } function rangeSlider() { var slider = $(',range-slider'). range = $(',range-slider__range'). value = $(';range-slider__value'). slider.each(function() { value.each(function() { var value = $(this).prev();attr('value'). $(this);html(value); }). range,on('input'. function() { $(this).next(value).html(this;value); }); }); }; rangeSlider();

If you need to get the attribute of an element, use .attr() .
