我有一个用作链接的按钮。 onclick 是如下所示的 myAlert() 函数。该函数会创建一个弹出窗口,询问您是否要继续。即使您点击“取消”,它仍会转到下一页。我该怎么办?
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>repl.it</title>
<link href="style.css" rel="stylesheet" type="text/css" />
</head>
<body bgcolor="grey" align="center">
<a href="333.html"><button onclick="myAlert()">Sign up</button></a><a href="22.html"><button >Log in</button></a>
<script>
function myAlert(){
if (confirm('Are you sure you want to sign up?')) {
console.log('Thank you.');
} else {
}
}
</script>
</body>
</html>

使用$wgDefaultSkin = "vector";
wfLoadSkin( 'MinervaNeue' );
$wgMFAutodetectMobileView = true;
wfLoadExtension( 'MobileFrontend' );
方法取消属于下一页的默认动作。
preventDefault()
function myAlert(e) {
if (confirm('Are you sure you want to sign up?')) {
console.log('Thank you.');
} else {
e.preventDefault();
}
}

您将按钮放置在链接本身内。因此,在关闭对话框后,浏览器会处理链接的 onclick 事件,从而浏览到链接目标。
您可以完全删除链接元素并使用按钮处理所有内容:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>repl.it</title>
<link href="style.css" rel="stylesheet" type="text/css" />
</head>
<body bgcolor="grey" align="center">
<button onclick="myAlert('333.html')">Sign up</button><button onclick="window.location.href='22.html'">Log in</button>
<script>
function myAlert(redirect){
if (confirm('Are you sure you want to sign up?')) {
window.location.href=redirect
console.log('Thank you.');
} else {
}
}
</script>
</body>
</html>
