1.通过prompt()提示用户作出响应

welcom5.html

<!DOCTYPE html>
<html>
<head>
  <title>Test prompt()</title>
  <h1>You can input your answer.</h1>
</head>
<body>
  <script src="script05.js"></script>
</body>
</html>


script05.js

var ans=prompt("Are you sure you want to do that?");
if(ans){
	alert("You said "+ans);
}
else{
	alert("You refused to answer.");
}


运行结果



2.通过将重定向(redirect)功能嵌入代码

welcome6.html

<!DOCTYPE html>
<html>
<head>
  <title>Welcome to my site!</title>
  <script src = "script06.js"></script>
</head>
<body>
  <h2 class = "centerd">
    <a href = "welcome5.html" id = "redirect">Welcome to my site...c'mon in!</a>
  </h2>
</body>
</html>


script06.js

window.onload = initAll;

function initAll(){
	document.getElementById("redirect").onclick = initRedirect;
}

function initRedirect(){
	window.location="welcome5.html";
	return false;
}


运行结果
