Question

//我需要将分页链接设置为实时搜索输出表。第一个搜索输出页面正确显示（页面上有8行），index.html中的页面计数正确，搜索文本框（search_text）的页面相同。（图1）

但是在选择第一页的分页链接的数字2 之后，可以看到下一个8行的搜索输出（数字可以看到第1张图片的底部）。它显示错误的输出（与搜索值无关）以及错误的页面“fetch.php”（图片2），即使它应该在 Index.php 上可见，与第一次输出相同。

我需要更正能够转到能够在同一页面显示更多搜索结果的分页链接（搜索结果的数量）的代码（index.html）

//在index.html中首先搜索输出（正确的第一个）

//具有正确页数的分页链接

//如果点击分页链接的第2个以查看接下来的8个搜索结果，则显示为贝娄。（错误的结果和错误的页面 fetch.php ，错误的分页链接）

// index.html用于输入搜索值和搜索结果输出
