【问题描述】：
不太确定为什么我的脚本不起作用我没有看到任何错误，如果有人能给我一些关于出了什么问题的见解，那就太好了。 我不确定引导程序是否存在干扰，因为我可以让它在没有应用 css 或引导程序的纯 html 中工作。

这是与 html 一起出现的脚本，我已经三次检查它是否正确链接并且所有内容都正确拼写，所以我很茫然，无法弄清楚发生了什么。
function getReceipt() {
var text1 = "<h3>You Ordered:</h3>;
var runningTotal = 0;
var sizeTotal = 0;
var sizeArray = document.getElementsByClassName("size");
}
for (var i = 0; i < sizeArray.length; i++) {
if (sizeArray[i].checked) {
var selectedSize = sizeArray[i].value;
text1 = text1+selectedSize+"<br>";
}
}
if (selectedSize === "Personal Pizza") {
sizeTotal = 6;
} else if (selectedSize === "Medium Pizza") {
sizeTotal = 10;
} else if (selectedSize === "Large Pizza") {
sizeTotal = 14;
} else if (selectedSize === "Extra Large Pizza") {
sizeTotal = 16;
}
runningTotal = sizeTotal;
console.log(selectedSize+" = $"+sizeTotal+".00");
console.log("size text1: "+text1);
console.log("subtotal: $"+runningTotal+".00");
getMeat(runningTotal,text1); // All three of these variables will be passed on to each function
};
function getMeat(runningTotal,text1) {
var meatTotal = 0;
var selectedMeat = [];
var meatArray = document.getElementsByClassName("meats");
for (var j = 0; j < meatArray.length; j++) {
if (meatArray[j].checked) {
selectedMeat.push(meatArray[j].value);
console.log("selected meat item: ("+meatArray[j].value+")");
text1 = text1+meatArray[j].value+"<br>";
}
}
var meatCount = selectedMeat.length;
if (meatCount > 1) {
meatTotal = (meatCount - 1);
} else {
meatTotal = 0;
}
【问题讨论】：
-
查看您帖子中格式化、突出显示的代码。 . .缺少什么？ （记录了任何控制台错误吗？）
-
“不起作用”是什么意思？请明确点。请阅读：stackoverflow.com/help/mcve
