android - disable image download on android browser

Question

how do I disable the functionality on Android browsers where a user can press and hold and image and bring up a "save image" popup dialog.

for ios devices, -webkit-touch-callout:none; works, but this seems to have no effect on android browsers

Answer 1

为调用 event.preventDefault() 的 click 事件附加一个事件处理程序。至少当我使用 ICS 的默认网络浏览器、chrome beta 和 opera mobile 时，这确实对我有用。
