敬告:此 DEMO 演示为开放测试页面,仅用于开发者快速测试体验应用功能,请严格遵守开发者协议,了解更多。
♦ JS-SDK 引用方式:
♦ 普通网页 script 方式加载:下载最新版 jsBridge-v20241118.zip,请在页面上调用 jsBridge 接口之前引用 jsbridge-mini.js 库;
♦ js module 方式引用:npm install ym-jsbridge 具体请参考 npm package
♦ APP端文件及目录管理;
♦ 提供本地文件/目录/下载/解压/哈希/分享/打开等操作接口;
♦ 本地文件路径规则:fs://{MainDirectory}/YourPath
♦ 仅允许如下两个主目录:
一般文件目录 fs://file/YourPath
缓存文件目录 fs://cache/YourPath
jsBridge.fs.mkdir("fs://file/my_dir/", function(succ, msg){ alert(succ ? "创建成功" : msg); });
jsBridge.fs.exist("fs://file/my_dir/", function(succ, msg){ alert(succ ? "存在" : "不存在"); });
jsBridge.fs.exist("fs://file/my_dir/my.txt", function(succ, msg){ alert(succ ? "存在" : "不存在"); });
• 回调参数 data 中以斜杠 / 结束的是子目录,否则是文件。
jsBridge.fs.list("fs://file/", function(succ, data) { alert("succ:" + succ + "\n" + JSON.stringify(data)); });
• 回调参数 data 中以斜杠 / 结束的是子目录,否则是文件。
jsBridge.fs.list("fs://file/my_dir/", function(succ, data) { alert("succ:" + succ + "\n" + JSON.stringify(data)); });
• 如果文件不存在则返回 0
jsBridge.fs.size("fs://file/my_dir/my.txt", function(succ, data) { alert("succ:" + succ + "\n" + data); });
• 如果指定的是目录,则会删除此目录及其目录下的所有文件。
jsBridge.fs.delete("fs://file/my_dir/", function(succ, msg) { alert(succ ? "删除成功" : msg); });
file:
jsBridge.fs.writeText( //文件路径,不存在则创建,已存在则覆盖 "{{text.file}}", //文本内容(UTF8编码) "Hello world!\n你好,世界!", //回调 function(succ, msg) { alert(succ ? "写入成功" : msg); } );
file:
jsBridge.fs.appendText( //文件路径,不存在则创建,已存在则追加到文件末尾 "{{text.file}}", //文本内容(UTF8编码) "\n这是追加的文本...", //回调 function(succ, msg) { alert(succ ? "追加成功" : msg); } );

• 记录文件下载状态,已下载的可以避免重复下载;
• 支持断点续传;
• 支持下载完成后自动打开文件;
