javascript - 为什么我的代码不从 if 语句输出字符串？

Question

这是我的代码:https://plnkr.co/edit/HFyKq2JZipwAAST0iNAt?p=preview为什么不将 if 语句的结果输​​出到 ID 为“WA”的标签这是与上面链接的代码分开的 IF 语句:

if (demlean.WA <= 5 && demlean.WA >= -5) {
        if (demlean.WA > 0) {
          var lWA = "Tossup, Tilt D";
        } else if (demlean.WA < 0) {
          var lWA = "Tossup, Tilt R";
        } else {
          var lWA = "Absolute Tossup";
        }

      } else if (demlean.WA > 5) {
        if (demlean.WA <= 10) {
          var lWA = "Lean D";
        } else if (demlean.WA <= 17) {
          var lWA = "Likely D";
        } else {
          var lWA = "Safe D";
        }
      } else {
        if (demlean.WA >= -10) {
          var lWA = "Lean R";
        } else if (demlean.WA >= -17) {
          var lWA = "Likely R";
        } else {
          var lWA = "Safe R";
        }
 }
.... // more code

好的，我终于可以运行您的代码了，这是我所做的修改。首先，

Uncaught ReferenceError: dDe is not defined
    at calc ((index):140)
    at submit ((index):153)
    at HTMLButtonElement.onclick ((index):167)

所以我将这一行更改为 DE: dDE,。然后另一个错误

Uncaught ReferenceError: demlean is not defined
    at lean ((index):45)
    at calc ((index):146)
    at submit ((index):153)
    at HTMLButtonElement.onclick ((index):167)

demlean 是一个局部变量。所以我需要将其传递给精益功能。

    .....
    var geba;
    var tda;
    /* If Statement for determing lean in variable lSTATE */
    function lean(demlean) {
    .....
    .
    .
    .
    DE: dDE,
    MD: dMD,
    NY: dNY,
    VT: dVT,
    ME: dME,
    HI: dHI
  };
  // passing demlean here.
  lean(demlean);
