直接从 Android 文件管理器打开 html 页面时如何正确设置背景图像的绝对路径
How to correctly set the absolute path of a background-image when opening an html page directly from Android File Manager
我正在 Android 中使用 droidEdit 创建一个简单的 html 页面，就这么简单。
在此页面中，有一个 div 带有背景。
此背景是本地存储的图像，但 url 必须是（出于多种原因）绝对路径，而不是相对路径，特别是这样的路径：file:///sdcard/assets/images/test。动图
现在，如果我打开我的页面并打开 Chrome 并导航到文件:///sdcard/index。html 一切正常，我可以看到我的 div与他漂亮的动画背景。
我的问题是，如果我直接从文件管理器打开 index.html，Chrome 会启动并正确显示 index.html，但 div 根本不显示任何背景。
我不是 Android 系统如何在表面下工作的专家，但由于相同的代码（当然具有不同的 file:/// 路径）在 Windows 中工作，我怀疑 Android 以某种方式使用不同的 url/uri 系统来处理本地存储的文件。
当我直接从文件管理器打开 index.html 时，有什么方法可以设置 test.gif 的正确（绝对）路径以使 css 正确加载它？
提前致谢
直接导航到 chrome 中的文件时，访问本地图像有效。由于浏览器强加的安全规则，从另一个页面打开 html 文件时它不会工作。在此处查看完整详细信息：https://blog.chromium.org/2008/12/security-in-depth-local-web-pages.html
可以通过使用任何在线工具（搜索 base64 image）对图像进行 base64 编码并将结果用作背景来修复：

我正在 Android 中使用 droidEdit 创建一个简单的 html 页面，就这么简单。 在此页面中，有一个 div 带有背景。 此背景是本地存储的图像，但 url 必须是（出于多种原因）绝对路径，而不是相对路径，特别是这样的路径：file:///sdcard/assets/images/test。动图
现在，如果我打开我的页面并打开 Chrome 并导航到文件:///sdcard/index。html 一切正常，我可以看到我的 div与他漂亮的动画背景。 我的问题是，如果我直接从文件管理器打开 index.html，Chrome 会启动并正确显示 index.html，但 div 根本不显示任何背景。
我不是 Android 系统如何在表面下工作的专家，但由于相同的代码（当然具有不同的 file:/// 路径）在 Windows 中工作，我怀疑 Android 以某种方式使用不同的 url/uri 系统来处理本地存储的文件。
当我直接从文件管理器打开 index.html 时，有什么方法可以设置 test.gif 的正确（绝对）路径以使 css 正确加载它？
提前致谢
直接导航到 chrome 中的文件时，访问本地图像有效。由于浏览器强加的安全规则，从另一个页面打开 html 文件时它不会工作。在此处查看完整详细信息：https://blog.chromium.org/2008/12/security-in-depth-local-web-pages.html
可以通过使用任何在线工具（搜索 base64 image）对图像进行 base64 编码并将结果用作背景来修复：
