javascript - 在循环中调用 ajax，它不会执行 2 次
问题描述
我正在处理一个 MVC 项目，在一个视图中我需要一个脚本来进行 Ajax 调用以进行计算，我有 N（最多 5 个）对象要填充，每次我运行脚本时，都会有一个循环重复 N 次对象很多，但是，在 Ajax 调用时，循环重新开始，变量在所有代码执行之前递增，
我会向您展示代码，如果没有正确执行，请见谅：
function TestFunction(c) {
for (var k = 0; k < @TempData["num_bal_simu"]; k++) {
var newvalue = c.getElementsByClassName("valuesheet")[0].value;
var testAttribute = c.getElementsByClassName("valuesheet")[0];
var getNameAttributeReplace = testAttribute.getAttribute('name').split(".");
var array = testAttribute.id.split("_");
indexbalancesheetFor = array[4];
var indiceBalanceSheet = parseInt(getNameAttributeReplace[0][getNameAttributeReplace[0].length - 2]);
stringa = "SimulatedBalance" + "Input" + "_" + "0";
if (indiceBalanceSheet == 0 && k == 0) {
var valueDropDownMode = document.getElementById(testAttribute.getAttribute('name')).value;
}
else {
var newstr = getNameAttributeReplace[0].replace(indiceBalanceSheet,'0');
var getAttributeNameModify = newstr + "." + getNameAttributeReplace[1] + "." + getNameAttributeReplace[2] + "." + getNameAttributeReplace[3];
var valueDropDownMode = document.getElementById(getAttributeNameModify).value;
}
if (indiceBalanceSheet == 0 && k == 0) {
var testAttribute2 = c.getElementsByClassName("valuesheet")[0].name;
var last_value = document.getElementById(testAttribute2).value;
}
else {
var newstr = getNameAttributeReplace[0].replace(indiceBalanceSheet, '0');
var testAttribute2 = newstr + "." + getNameAttributeReplace[1] + "." + getNameAttributeReplace[2] + "." + getNameAttributeReplace[3];
var counter = k - 1;
previousBalanceValue = document.getElementById("SimulatedBalance" + "_" + counter + "__" + "BalanceSheetIncome" + "_" + indexbalancesheetFor + "__Value_Hidden").value;
var last_value = previousBalanceValue;
}
if (antevalue != newvalue) {
var valuepunto = parseFloat(last_value.replace(",", "."));
switch (valueDropDownMode) {
case '0':
var val0 = (valuepunto * newvalue) / 100;
last_value = valuepunto + val0;
last_value.toString().replace('.', ',');
break;

}
for循环包含了整个脚本，我在互联网上读到只是通过输入使调用非异步async: false但这没有用，我已经卡在这里好几天了，请我需要帮助
