新人求教，为什么我无法将每5个数字进行换行打印，应该如何操作？
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<button onclick="buttom()">提交</button>
<div id="div1"></div>
</body>
<script>
function buttom() {
var q = '';
var count = 0;
for (var i = 20; i <= 80; i++) {
if (i % 3 == 0) {
q += i
if (count % 5 == 0) {
console.log(count);
document.getElementById('div1').innerHTML = q + "<br/>";
} else {
document.getElementById('div1').innerHTML = q;
};
count++
};
};
};
</script>
</html>
