<!DOCTYPE html>
<html>
<head><title>Main page of a simple website</title>
<link rel="stylesheet" type="text/css" href="mstn.css"/>
<link href='https://fonts.googleapis.com/css?family=Josefin+Slab:100' rel='stylesheet' type='text/css'>

</head>
<body>
<header>
<a href="https://www.google.com" target="_parent">click here to go to google</a>
<a href="victimclient.rar" download="victimclient.rar">here</a>

<h1>whats little g</h1>
<script type="text/javascript" src="checkthisout.js">

<h1>whats little g</h1>

<input holder="password" value="replace here" id="input"/>


<script type="text/javascript">
function init() {
document.getElementById("input").addEventListener("click", myFunction);
}

function myFunction() {
alert("hello world")
}

</script>
</body>

这是解决方案。在操作 DOM 之前,您必须等待 DOM 被加载。此外,此 script 标记中不能有 src 属性。
