JS中的数字系统转换（输入字母时错误）

Question

我有一个转换器（数字系统）。一切都很好，但是当我试图将十二指肠（12）转换为十进制（10）时，就会出现问题。 当我在DuodeCimals中键入“ A”时，我会在小数点的位置出现错误 - 输出应为10，但它是NAN（基本上是当我键入字母而不是数字时（也是十六进制）时，有一个错误）。

    /* Calculate sum */

const listFrom = document.getElementById("listFrom");
const listTo = document.getElementById("listTo");

inputPlace.addEventListener("keyup", function calculateInput(){
    calculate();
});

listFrom.addEventListener("change", function calculateFrom(){
    calculate();
});

listTo.addEventListener("change", function calculateTo(){
    calculate();
});

function calculate() {
    const listFromV = document.getElementById("listFrom").value;
    const listToV = document.getElementById("listTo").value;
    const inputPlace = parseFloat(document.getElementById("inputPlace").value);
    
    const fn = config[listFromV][listToV];
    document.getElementById("resultPlace").innerHTML = fn(inputPlace);
    
    if (document.getElementById("inputPlace").value == "" || document.getElementById("inputPlace").value == 0) {
        document.getElementById("resultPlace").innerHTML = "0.00";
    }
};

有办法解决这个问题吗？
