tp5页面输出时，搜索后跳转下一页的处理-php手册-php.cn

tp5页面输出时，搜索功能在跳转下一页时，如果不做任何处理，会返回原有是第二页输出的数据。为了保证跳转下一页时输出的是搜索到的数据，做以下处理。

（要根据自己的搜索字段进行适当修改）

页面js代码，给地址栏加上参数，以便于点击搜索按钮后台通过地址栏得到搜索条件。

$(document).ready(<span style="color: #0000ff;">function</span><span style="color: #000000;">(){<br>　　　　　<span style="color: #008000;">//点击搜索按钮执行搜索</span>
