File System Access 自动文件命名与冲突解决策略实践

概述良好的命名策略能降低覆盖与混淆风险。本文提供版本后缀与递增策略示例。命名与保存function makeName(base, ext, ts = Date.now()) { return `${base}-${ts}${ext ? '.'+ext : ''}`; } async function saveWithAutoName(base, blob, ext) { const name = makeName(base, ext); const h = await window.showSaveFilePicker({ suggestedName: name }); const ws = await h.createWritable(); await ws.write(blob); await ws.close(); }
