Question

到目前为止，我已经编写了以下代码：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<table style="width:10%">

</tr>

</td>
</table>
<button onclick="IVFunction()">Get IV</button>
<p id="checkar"></p>
</body>
<script>
function IVFunction() {
    var CS = parseInt(document.getElementById("C-Stat").value);
    var CL = parseInt(document.getElementById("C-Level").value);
    var BS = parseInt(document.getElementById("B-Stat").value);
    var ES = parseInt(document.getElementById("EV-Stat").value);
    var N = parseInt(document.getElementById("Nature").value);
    var WS = parseInt(document.getElementById("What-Stat").value);
    var done = "Please Enter A Valid Input";

    if (N=="Beneficial") {
        var N = 1.1;
    }
    else if (N=="Neutral") {
        var N = 1.0;
    }
    else if (N=="Detrimental") {
        var N = 0.9;
    }

    if (WS == "HP") {
        var HPIV1 = ((CS-10)*100)/CL;
        var HPIV2 = HPIV1 - (2*BS) - (ES/4) - 100;
        var done = HPIV2;
    }
    else if (WS != "HP") {
        var IV1 = ((CS/N - 5)*100)/CL;
        var IV2 = IV1 - (2*BS) - (ES/4);
        var done = IV2;
    }
    document.getElementById("checkar").innerHTML = done;
}
</script>
</html>

代码向用户显示一个表，然后同时获取文本和选择框输入以运行脚本代码。我想在代码中修复的是选择选项。在脚本部分中，我概述了一些条件，这取决于用户选择哪些选项作为输入，但是我不确定如何实际使用这些值作为脚本代码的输入;特别是关于设定N值的部分。

非常感谢任何帮助：）

你的问题是这两行：

var N = parseInt(document.getElementById("Nature").value);
var WS = parseInt(document.getElementById("What-Stat").value);

您尝试将单词解析为整数。

删除parseInt()，你应该好好去：

function IVFunction() {
    var CS = parseInt(document.getElementById("C-Stat").value);
    var CL = parseInt(document.getElementById("C-Level").value);
    var BS = parseInt(document.getElementById("B-Stat").value);
    var ES = parseInt(document.getElementById("EV-Stat").value);
    var N = document.getElementById("Nature").value;
    var WS = document.getElementById("What-Stat").value;
    var done = "Please Enter A Valid Input";

    if (N == "Beneficial") {
        var N = 1.1;
    } else if (N == "Neutral") {
        var N = 1.0;
    } else if (N == "Detrimental") {
        var N = 0.9;
    }

    if (WS == "HP") {
        var HPIV1 = ((CS - 10) * 100) / CL;
        var HPIV2 = HPIV1 - (2 * BS) - (ES / 4) - 100;
        var done = HPIV2;
    } else if (WS != "HP") {
        var IV1 = ((CS / N - 5) * 100) / CL;
        var IV2 = IV1 - (2 * BS) - (ES / 4);
        var done = IV2;
    }
    document.getElementById("checkar").innerHTML = done;
}

Answer 2

您不应将parseInt()用于N和WS，并且代码中有许多重新定义的变量。更重要的是，将所有样式放在css文件中。

function IVFunction() {
  var CS = parseInt(document.getElementById("C-Stat").value);
  var CL = parseInt(document.getElementById("C-Level").value);
  var BS = parseInt(document.getElementById("B-Stat").value);
  var ES = parseInt(document.getElementById("EV-Stat").value);
  var N = document.getElementById("Nature").value;
  var WS = document.getElementById("What-Stat").value;
  var done = "Please Enter A Valid Input";

  if (N == "Beneficial") {
    N = 1.1;
  } else if (N == "Neutral") {
    N = 1.0;
  } else if (N == "Detrimental") {
    N = 0.9;
  }

  if (WS == "HP") {
    var HPIV1 = ((CS - 10) * 100) / CL;
    var HPIV2 = HPIV1 - (2 * BS) - (ES / 4) - 100;
    done = HPIV2;
  } else if (WS != "HP") {
    var IV1 = ((CS / N - 5) * 100) / CL;
    var IV2 = IV1 - (2 * BS) - (ES / 4);
    done = IV2;
  }

  document.getElementById("checkar").innerHTML = done;
}
