jQuery/Javascript Ajax POST 在 .each 循环中创建 6 个重复的帖子，大约 20% 的时

背景：jQuery mobile phonegap 构建多页-ajaxload sisyphus enabled form with a ajax POST 循环到 GUI 数据库。有171个科员额，外加1个汇总员额到另一个表格。（这些数据可能应该是后端处理逻辑的帖子，不幸的是我没有访问权限或时间在后端解决此问题）。大约 80% 的时间，此功能会发布 171 个预期部分（加上 1 个摘要帖子）。但是，在20%的情况下，有6个重复的帖子，总共177个帖子。我尝试过 async：false，但性能受到了重大影响。

为什么有 6 个随机重复的帖子大约 20% 的时间？修复此 ajax post 循环的最佳方法是什么，以便没有任何跳过的帖子或任何重复的帖子？

jQuery Ajax 171 Post Loop：

尝试在移动设备上复制此问题是一项挑战。任何意见或建议都会很棒！
