【问题描述】：
在我们的页面中，有 1 个输入必须由用户手动输入。根据他输入的内容，显示了一些记录，每个结果旁边都有禁用或启用（例如，我输入12345，结果是A，B，C，D，4个结果和除了这些结果之外，还有禁用按钮侧。）。目前，发生的情况是当我单击“禁用”或“启用”时，页面会自动重新加载，但我找不到修复它的方法。无论如何要停止重新加载？我使用window.history.go(-1)。它会更新数据库，但每次我禁用或启用时页面都会重新加载。
下面是HTML代码。

-
您不必单击链接，而是必须使用 AJAX，将必要的参数发送到服务器，并在 JavaScript 中处理响应。
-
身份证属性必须是唯一的，因此在循环中生成多个元素将打破该规则
-
@CBroe 我以前从未使用过 ajax。你能给我举个例子吗？
