我正在制作一个程序，其中有一组计算器，出于某种原因，当我试图更改某个文本的innerhtml时，它只在if语句期间更改，而在else部分不更改。
function Palindrome() {
//Fix not changing to processing when doing new palindrome.
var Division = 0;
var input = document.getElementById("PalindromeInput").value;
var GiveAnswer = document.getElementById("PalindromeAnswer");
var Answer = String(input);
while (0 < 1) {
if (Answer == Answer.split("").reverse().join("")) {
GiveAnswer.innerHTML = `That is a palindrome of the ${Division}th Division.`;
break
} else {
GiveAnswer.innerHTML = `Processing...`;
Division = Division + 1;
Answer = String(parseInt(String(Answer)) + parseInt(Answer.split("").reverse().join("")));
};
};
}；

我不确定，但我想原因是函数从未进入else部分，因为它每次都会得到break。请记住，.reverse()在适当的位置反转数组，因此if语句将始终为true。尝试为相反的答案添加不同的变量。
function Palindrome() {
//Fix not changing to processing when doing new palindrome.
var Division = 0;
var input = document.getElementById("PalindromeInput").value;
var GiveAnswer = document.getElementById("PalindromeAnswer");
var Answer = String(input);
GiveAnswer.innerHTML = `Processing...`;
setTimeout(()=>{
while (0 < 1) {
if (Answer == Answer.split("").reverse().join("")) {
GiveAnswer.innerHTML = `That is a palindrome of the ${Division}th Division.`;
break
} else {
Division = Division + 1;
Answer = String(parseInt(String(Answer)) + parseInt(Answer.split("").reverse().join("")));
};
};
},1000)

</html>结果是渲染速度非常快，所以更改不会反映在ui中。。添加一个超时，以便更改反映在前端中
