我正在尝试做一个猜数字游戏，正确的输出应该逐行显示:尝试 1 你的猜测 xx 太小(大) 尝试2 你的猜测xx太小(大) 尝试2 你的猜测xx太小(大) ...
但我的输出总是在同一行发生变化，如下所示: 尝试3 你的猜测xx太小(大) 不知道问题所在，请帮忙。

最佳答案
如果您尝试保留以前的结果并继续将其添加到列表中，请尝试以下操作:
if (myNumber<theNumber){
var parSmall = document.createElement("P");
var ansSmall = document.createTextNode("\nAttempt "+i+" Your guess "+ myNumber+ " is too small");
parSmall.appendChild(ansSmall);
document.getElementById("myguess").appendChild(parSmall);
}
else if (myNumber>theNumber) {
var par = document.createElement("P");
var ans = document.createTextNode("\nAttempt "+i+" Your guess "+ myNumber+ " is too big");
par.appendChild(ans);
document.getElementById("myguess").appendChild(par);
编辑:innerHTML 更改 div 的内容，而这会向 div 添加新的
元素和新文本，因此您应该得到:
<p> guess one
<p> guess two
<p> guess three
等等
