Javascript表单计算输出

我有一张表格,用于计算每平方米天花板的价格。 离子范围滑块作为输入,然后计算价格并将数据输出到输入。但我需要使用spandiv更改输入。有什么建议吗?

这是html:

<form id="calc">
  <div id="1">

  <p> 
    <input id="rel"  oninput="
    var v = this.value; 
    this.form.new.value = isNaN(v) ? '' : (v * 450).toFixed (0); 
    var v = this.value; this.form.new2.value = isNaN(v) ? '' : (v * 650).toFixed (0)" 
    style="display: none;">
  </p>

  <p><p>
   <span  class="small">from </span>
<span class="new"></span>
   <input type="text" disabled="disabled" name="new" size="2" maxlength="4" value="0" >
    <span class="small">to </span><input type="text" disabled="disabled" name="new2" size="2" maxlength="4" value="0">
    <div class="result" id="result">

    </div>
  </p>

  </div>
</form>

@media screen and (-webkit-min-device-pixel-ratio:0) {

      background-color: #9a905d;

<script>

function E (ele) {return document.getElementById(ele)}
function CALC ( value_ ) {

    var SPAN = E("SliderValue")
    var FROM = E("FROM")
    var TO = E("TO")
    var currentValue = E("SliderValue")
    
    var WIDTH_OF_SLIDER = E("rel")
    
    var positionInfo = WIDTH_OF_SLIDER.getBoundingClientRect();
    var width_IN_PIX = positionInfo.width;

    FROM.value = isNaN(value_) ? '' : (value_ * 450).toFixed (0); 
    TO.value = isNaN(value_) ? '' : (value_ * 650).toFixed (0);
    
    currentValue.innerHTML = value_ + ""
    
    var COEFICIJENT =  width_IN_PIX / 100
   
    currentValue.style.left = ( value_ * COEFICIJENT ) + "px"
    
    
}
