Safari iPad:防止双击放大 [英] Safari iPad : prevent zoom on double-tap

问题描述

我正在 iPad 版 Safari 上创建网站.我需要阻止双击事件的缩放，但我有两个问题:

I'm creating a site on Safari for iPad. I need to prevent the zoom on double-tapping event but I have two problems:

• 双击不会产生任何事件，所以我不能使用event.preventDefault();"
• 我只在满足某些条件时才需要这样做，所以我不能使用标签...如果我这样做，用户将永远无法放大我的页面.

• a double tap doesn’t generate any events, so I can't use "event.preventDefault();"
• I need to do this only when some conditions are fulfilled, so I can't use the tag "<meta name = "viewport" content = "user-scalable = no">"... If I did that, users could never zoom on my page.

我该如何解决这些问题?

How can I fix these problems?

推荐答案

Mobile Safari 不支持 javascript ondblclick 事件.Safari 将其解释为缩放".

Mobile Safari does not support the javascript ondblclick event. It's interpreted by Safari as a "zoom".
