按下计算按钮时未执行Java代码

Question

试图创建计算器以计算大小和输出结果的差异

这是脚本使用。

用于计算基准直径的脚本签出-https://code.sololearn.com/wahq9E8aL5I3

<script language="JavaScript" type="text/JavaScript">
      function Calculate1 ( section1, profile1, diameter1 ) {
         rollingradius1=Math.round((((diameter1/2)*25.4)+(section1*(profile1/100)))*100)/100;
         circumference1=Math.round((rollingradius1*2*3.14159)*100)/100;
         document.wheelsizes.rollingradius1.value=rollingradius1;
         document.wheelsizes.circumference1.value=circumference1;
      }
      function Calculate2 ( section2, profile2, diameter2 ) {
         rollingradius2=Math.round((((diameter2/2)*25.4)+(section2*(profile2/100)))*100)/100;
         circumference2=Math.round((rollingradius2*2*3.14159)*100)/100;
         document.wheelsizes.rollingradius2.value=rollingradius2;
         document.wheelsizes.circumference2.value=circumference2;
      }
      function Difference ( circumference1, circumference2 ) {
         difference=Math.round((circumference2-circumference1)*100)/100;
         differencepercent=Math.round(((difference/circumference1)*100)*100)/100;
         realspeed=Math.round((((differencepercent/100)*70)+70)*100)/100;
         document.wheelsizes.difference.value=difference;
         document.wheelsizes.differencepercent.value=differencepercent;
         document.wheelsizes.realspeed.value=realspeed;
      }
    </script>

和表格是

尽管这在某些站点上是可以使用的计算器，但是在按下计算按钮时无法获得任何结果任何建议使其正常工作

可能对您有帮助，我只为calulate1写代码”>

 function getVal(ctrlid){
 var e = document.getElementById(ctrlid);
  var result = e.options[e.selectedIndex].text;
  return result
 }
 function SetVal(ctrlid,values){
 document.getElementById(ctrlid).value=values;
 }
 function Calculate1 (  ) {
 section1=getVal("section1")
 profile1=getVal("profile1")
 diameter1=getVal("diameter1")

         rollingradius1=Math.round((((diameter1/2)*25.4)+(section1*(profile1/100)))*100)/100;

     circumference1=Math.round((rollingradius1*2*3.14159)*100)/100;
      SetVal("rollingradius1",rollingradius1)
  SetVal("circumference1",circumference1)
