我为我的网页翻译创建了“管理菜单”，包括图片，所以你在图片中。
这很简单，我将所有内容保存到数据库中，当我进行更改时，我会重新生成所需的文件，例如。/languages/english/tank_auth_lang.php. 每当我想翻译/编辑某些内容时，我只需单击字段编辑并单击字段外 AJAX 将 POST 发送到我的控制器，该控制器负责插入/更新/添加翻译。
问题
这是我的功能，但每当我快速重新发送（重新编辑/向表中添加新翻译）时，有时我会在数据库中重复。有什么我应该避免做的吗？（比如在发送前等待或其他东西）。
如果我进行分析，它会告诉我有 2 个相同的插入（不是在一个 AJAX 调用中，而是在两个连续的快速AJAX 调用中）。
函数本身一开始很复杂，因为每当 ( strlen()) 值比 524 长时，我都会以不同的方式保存它（我将它保存在结构TEXTnot的表中VARCHAR(524)）。
