js打开网页自动复制功能代码,打开网页自动复制支付宝红包口令

最近发现在逛某些网站的时候,打开网页就会自动复制某些文字内容到剪切板上面,特别是近期比较火的支付宝红包代码。

js打开网页自动复制功能代码

很多用户包括我自己,有时候逛了一圈网页,出去买东西打开支付宝的时候就会自动弹出红包领取,如下图所示:

你可能以为是自己走运获得了支付宝的红包,或者是支付宝自动发了红包给你,其实是在打开某个网页的时候,被自动复制了一串红包代码。

那么代码是什么样的呢,这种代码对于推广支付宝确实非常不错。

自动复制代码

代码这里分享给大家,不过需要大家点击网页才会自动复制:

<script src="https://cdn.bootcss.com/clipboard.js/1.5.9/clipboard.js"></script>
<script type="text/javascript">
var clipboard = new Clipboard('body', {
text: function() {
return "快来领取支付宝跨年红包!11日起还有机会额外获得专享红包哦!复制此消息,打开最新版支付宝就能领取!nODK2U58Er";
}
});
clipboard.on('success', function(e) {
alert('复制成功,打开最新版支付宝就能领取红包')
});
clipboard.on('error', function(e) {
alert('您的浏览器不支持点击复制')
});
</script>

不过大多数浏览器都需要点击才能自动复制,用户不点击是没法发自动复制的。

代码默认会弹出消息提示,我们只需要删除代码中的alert即可取消提示。

此代码支持电脑和手机。

对于用户来说也是一种好事,使用红包付款可以节约不少钱,这个红包每天都可以领取,每次付款都可以抵消。

JS自动复制代码在第二页,如果代码中链接失效,可以自己保存本地。
