如何修复代码在单个数据库中使用 20 个 datalist HTML 标签在 datalist 中显示 1000 行但在 datalist 中只显示前 512 行？

Question

如何修复代码在单个数据库中使用 20 个 datalist HTML 标签在 20 个 datalist HTML 标签中显示 1000 行，但在 20 个 datalist HTML 标签中只显示前 512 行？

因为我尝试编码，但不能在单个数据库中使用 20 个 datalist HTML 标记来显示 20 个 datalist HTML 标记中的 1000 行。

底部的示例代码。

1. testdata.sql （SQL 代码）

CREATE TABLE `testdata` (
  `testdata` int(11) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

INSERT INTO `testdata` (`testdata`) VALUES

Answer 1

好消息 1 ：我有答案来修复代码“使用 20 个数据列表 HTML 标签和单个数据库来显示数据列表中的 1000 行，但只显示数据列表中的前 512 行”问题，因为使用谷歌浏览器测试代码 -> 只显示前 512 行在数据列表和其他浏览器（例如：Internet Explorer 和 Microsoft Edge Legacy）中显示数据列表中的所有 1000 行，我等待 Google 修复带有链接的错误。

好消息 2 ：我的答案是只连接 1 个数据库以与我的完整源代码一起使用任何 datalist HTML 标记（例如与 10 个 datalist HTML 标记一起使用）。

  `testdata` int(11) DEFAULT NULL
