不显示错误详细信息,而是显示整个javascript.下标和上标也不显示!

我只是不太了解这两行：
document.getElementById('txt').innerHTML=h+":"+m+":"+s;
t=setTimeout('startTime()',500);
有人可以用语言解释吗？getElementById（'txt'），innerHTML和setTimeout（'startTime（）'，500）有什么作用？
var fruits = ["Banana", "Orange", "Apple", "Mango"];
fruits = fruits.sort();
document.write(fruits);
for(var i = 0; i < Math.ceil(fruits.length / 2); i++) {
var temp = fruits[i];
fruits[i] = fruits[fruits.length - 1 - i];
fruits[fruits.length - 1 - i] = temp;
}
document.write(fruits);
我试图反转有序(az)数组的结果,以便在for循环中使其成为za.为什么这不起作用？
我希望div'divi'显示输入框'hitbox'中的内容.
编辑:在这里放置这些代码并不困难,特别是如果这么短
document.getElementById('hitbox')
.onchange(document.getElementById('divi')
.innerHTML = document.getElementById('hitbox').value;
我想不出来..
