我正在尝试使用JavaScript创建一些html <p>和<div>标记，其中包含一些信息。我遇到的问题是我的totalAmountPrintOut函数只返回<p>＆gt;中的1个#printDivOut<div标记当我希望它返回8.如果有人能帮我解决这个问题，我真的很感激。

你错过了一个＆＃34; +＆＃34;将html分配给amountPrintOutDiv.innerHTML。
amountPrintOutDiv.innerHTML = "<p>" + "The total amount flour from the recipes is " + this.body1 + " cups." + "</p>";
amountPrintOutDiv.innerHTML += "<p>" + "The total amount flour from the recipes is " + this.body2 + " cups." + "</p>";
amountPrintOutDiv.innerHTML += "<p>" + "The total amount flour from the recipes is " + this.body3 + " cups." + "</p>";
amountPrintOutDiv.innerHTML += "<p>" + "The total amount flour from the recipes is " + this.body4 + " cups." + "</p>";
amountPrintOutDiv.innerHTML += "<p>" + "The total amount flour from the recipes is " + this.body5 + " cups." + "</p>";
amountPrintOutDiv.innerHTML += "<p>" + "The total amount flour from the recipes is " + this.body6 + " cups." + "</p>";
amountPrintOutDiv.innerHTML += "<p>" + "The total amount flour from the recipes is " + this.body7 + " cups." + "</p>";
amountPrintOutDiv.innerHTML += "<p>" + "The total amount flour from the recipes is " + this.body8 + " cups." + "</p>";

问题是你没有在innerHTML上添加文字，你只需要重新分配8次。尝试这样的事情：
amountPrintOutDiv.innerHTML = "<p>text..." + this.body1 + "</p>" +
"<p>text..." + this.body2 + "</p>" +
"<p>text..." + this.body3 + "</p>" +
"<p>text..." + this.body4 + "</p>";
或者，如果你必须追加，你可以这样做：
amountPrintOutDiv.innerHTML = "<p>text..." + this.body1 + "</p>";
amountPrintOutDiv.innerHTML += "<p>text..." + this.body1 + "</p>";
amountPrintOutDiv.innerHTML += "<p>text..." + this.body2 + "</p>";
amountPrintOutDiv.innerHTML += "<p>text..." + this.body2 + "</p>";
另外，如果您发现自己编写了非常重复的代码，也许可以考虑如何将其置于循环中。
