我正在寻找提交按钮棒的输出

Question

function submission() {

   //Variables ("now in getFormData()");
const S = document.getElementById("stockprice");
const SP = document.getElementById("strikeprice");

const B = document.getElementById("expirationdate");
const V = document.getElementById("vix");
const RF = document.getElementById("RFR");

const Callprice = parseInt(S.value) + parseInt(SP.value);

var input1 = document.getElementById("call");
input1.value = Callprice;
};

我希望在代码正常运行时让Callprice坚持下去，但答案很快就会消失。谢谢
