safari reload blank

本文描述了一个在Safari浏览器中遇到的问题:当网页源代码中包含空的<script language=javascript></script>标签时,虽然可以正常打开网页,但在刷新页面时会显示为空白。
在html中写了空的<script language="javascript"> </script>
可以在safari中打开网页,但是reload的时候显示空白页。

Delphi 12.3 作为一款面向 Windows 平台的集成开发环境,由 Embarcadero Technologies 负责其持续演进。该环境以 Object Pascal 语言为核心,并依托 Visual Component Library(VCL)框架,广泛应用于各类桌面软件、数据库系统及企业级解决方案的开发。在此生态中,Excel4Delphi 作为一个重要的社区开源项目,致力于搭建 Delphi 与 Microsoft Excel 之间的高效桥梁,使开发者能够在自研程序中直接调用 Excel 的文档处理、工作表管理、单元格操作及宏执行等功能。 该项目以库文件与组件包的形式提供,开发者将其集成至 Delphi 工程后,即可通过封装良好的接口实现对 Excel 的编程控制。具体功能涵盖创建与编辑工作簿、格式化单元格、批量导入导出数据,乃至执行内置公式与宏指令等高级操作。这一机制显著降低了在财务分析、报表自动生成、数据整理等场景中实现 Excel 功能集成的技术门槛,使开发者无需深入掌握 COM 编程或 Excel 底层 API 即可完成复杂任务。 使用 Excel4Delphi 需具备基础的 Delphi 编程知识,并对 Excel 对象模型有一定理解。实践中需注意同 Excel 版本间的兼容性,并严格遵循项目文档进行环境配置与依赖部署。此外,操作过程中应遵循文件访问的最佳实践,例如确保目标文件未被独占锁定,并实施完整的异常处理机制,以防数据损毁或程序意外中断。 该项目的持续维护依赖于 Delphi 开发者社区的集体贡献,通过定期更新以适配新版开发环境与 Office 套件,并修复已发现的问题。对于需要深度融合 Excel 功能的 Delphi 应用而言,Excel4Delphi 提供了经过充分测试的可靠代码基础,使开发团队能更专注于业务逻辑与用户体验的优化,从而提升整体开发效率与软件质量。 资源来源于网络分享,仅用于学习交流使用,请勿用于商业,如有侵权请联系我删除!
### iOS 18 Safari 中 `location.reload()` 方法的使用说明与错误处理 #### 方法概述 `location.reload()` 是 JavaScript 的内置方法,用于重新加载当前文档。它接受一个布尔参数,如果设置为 `true`,则强制从服务器重新加载页面;如果未提供该参数或设为 `false`,则可能从缓存中加载页面。 然而,在某些特定环境中(如微信浏览器、Vue 路由场景),或者在同版本的 Safari 浏览器中,可能会遇到兼容性问题[^5]。对于 iOS 18 上的 Safari 浏览器,以下是一些已知的行为和解决方案: --- #### 已知行为 1. **默认缓存机制** 在现代浏览器中,包括 iOS 18 的 Safari,`location.reload()` 默认尝试从缓存中加载资源。这可能导致开发者无法观察到预期的效果,尤其是在开发阶段需要频繁更新文件的情况下[^4]。 2. **微信环境下的限制** 微信内置浏览器对 `location.reload()` 存在特殊限制,调用此方法通常会被忽略或失败。虽然这是 iOS 18 Safari 的问题,但如果应用需支持微信分享链接,则应考虑替代方案。 3. **HTTPS 协议的影响** 如果网站运行于 HTTPS 下,部分旧版 Safari 可能会对相对路径跳转产生异常反应,尽管这一问题主要集中在更早版本(如 Safari 8.0)。但在调试过程中仍需注意网络请求的安全性和一致性[^1]。 --- #### 解决方案 针对上述情况,可以采取以下措施来确保 `location.reload()` 正常工作: 1. **强制刷新** 明确传递 `true` 参数给 `location.reload()`,从而绕过缓存并直接向服务器发起新请求: ```javascript window.location.reload(true); ``` 2. **检测事件状态** 对于一些特殊情况(例如页面被恢复而非正常加载的情况),可以通过监听 `onpageshow` 和 `event.persisted` 属性判断是否需要手动触发刷新操作: ```javascript window.onpageshow = function(event) { if (event.persisted) { window.location.reload(true); } }; ``` 3. **替换 URL 方案** 若发现 `location.reload()` 生效,可改用修改地址栏的方式实现类似效果。这种方法尤其适用于 Vue 等前端框架中的单页应用场景: ```javascript const timestamp = new Date().getTime(); window.location.href = `${window.location.pathname}?t=${timestamp}`; ``` 4. **跨平台适配** 针对微信或其他第三方客户端内的嵌入式 WebView,建议优先测试其对标准 API 的支持程度,并准备备用逻辑。例如利用 `setTimeout` 延迟执行命令以规避潜在冲突: ```javascript setTimeout(() => { try { window.location.reload(true); } catch (e) { console.error('Reload failed:', e.message); window.location.assign(window.location.href); } }, 500); ``` 5. **Cookie 同步注意事项** 当涉及登录态保持时,务必确认 SFSafariViewController 是否正确同步了原生 Safari 的 Cookie 数据[^3]。否则即使成功完成了页面重定向也可能因缺少必要的认证信息而报错。 --- #### 示例代码片段 以下是综合以上策略的一个完整例子: ```javascript // 尝试安全地刷新当前页面 function safePageRefresh() { let reloadAttempted = false; // Step A: Try standard method first. try { window.location.reload(true); reloadAttempted = true; } catch (_) {} if (!reloadAttempted || !navigator.userAgent.includes('Safari')) { // Fallback B: Append query string to force update without cache hit. const currentUrl = window.location.href.split('?')[0]; window.location.replace(`${currentUrl}?_ts=${Date.now()}`); } // Optional C: Handle edge cases like WeChat restrictions gracefully here... } ``` ---
