这段代码的onclick没有执行,是因为click()函数的语法有误,应该写成function click() {}的形式。另外,onload事件后的click()函数定义应该放在window.onload函数外面,或者使用匿名函数包装。修改后的代码如下:
```
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
<link rel="stylesheet" href="css.css">
<script src="3.js"></script>
</head>
<body>
<div id="rct" onclick="click()"></div>
<button class="butt" onmousedown="click()">ss</button>
</body>
<script>
function click() {
var rct = document.getElementById('rct');
rct.style.backgroundColor = "#003366";
console.log("a");
}
window.onload = function() {
alert("1100");
click();
}
</script>
</html>
```
