uniapp H5禁止微信浏览器长按出菜单，只针对图片

一、问题描述

如图：

uni-image>img,img {pointer-events: none;-webkit-pointer-events: none;-ms-pointer-events: none;-moz-pointer-events: none;
}uni-image::before {content: ' ';position: absolute;top: 0;bottom: 0;left: 0;right: 0;background: transparent;opacity: 0;
}

这样对img覆盖了一层蒙版，也就不会出现长按菜单了
只针对图片长按禁用
