javascript - 按下计算按钮时未执行Javascript

尝试创建计算器以计算大小和输出结果的差异

这是脚本使用的。

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 getVal(ctrlid){
 var e = document.getElementById(ctrlid);

 }
 function Calculate1 (  ) {
 section1=getVal("section1")

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

      SetVal("rollingradius1",rollingradius1)

虽然这在某些站点上是可以使用的计算器，但是按“计算”按钮无法获得任何结果
任何建议使其正常工作
第二个计算按钮不起作用，再次尝试

最佳答案

试试这个代码，它是完全复制

  return result

         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)
      }
