html - Safari 邮寄地址 : "This website has been blocked from automatically composing an email."

Question

当使用 Safari (iOS 10.2) 并单击 mailto 链接时，将显示确认提示和以下消息:

"This website has been blocked from automatically composing an email." Ignore / Allow

我想在我自己的网站上摆脱它，但不知道该怎么做。它可以用 Safari 重现，例如在任何 BBC 文章上单击邮件图标。

Issues with Safari and "This website has been blocked from automatically composing an email."

My research on Google suggests that this Error-type Message started happening in about November with an update to Safari, which likely occurred concurrently with Apple's update to iOS 10.2. As of today (1/11/17) that is the latest version of iOS for iPads and perhaps iPhones, too.

Release 15 URL Handling

Navigations to tel: and mailto: links now require a user gesture; navigations without a user gesture will show a confirmation prompt

所以它看起来像是 Safari 的“功能”。有谁知道如何防止这个提示？

Answer 1

各种第三方 JavaScript 库将拦截对 a 标签的点击，以防止在向服务器发送数据时短暂导航。通常，它们通过 window.location.replace 以编程方式触发导航。

当以这种方式触发 mailto/tel 链接时，Safari 中的更改会弹出警告。

有一个交互，但通常被 preventDefault 停止，Safari 不关心。

如果您使用的库导致此问题，请联系创建者，看看他们是否可以更新它以跳过 mailto/tel 链接上的 preventDefault。
