Javascript jqGrid查询中的子句
我有一个工作非常好的网格。我需要做的是根据某些条件从数据库返回某些字段,例如通过执行Javascript jqGrid查询中的子句,javascript,jquery,mysql,sql,jqgrid,Javascript,Jquery,Mysql,Sql,Jqgrid,我有一个工作非常好的网格。我需要做的是根据某些条件从数据库返回某些字段,例如通过执行 SELECT * FROM table WHERE reviewed = 0; 我希望这些结果在加载时显示在网格上,但我也希望能够使用网格上的高级搜索。我是jqgrid的新手,我已经在这个问题上讨论了很长时间了。这是我的原始代码 //Get the requested page $page = $_GET['page']; //Get how many rows we want to have into
SELECT * FROM table WHERE reviewed = 0;

首先mysql\uxxxxx…
已被弃用,因此最好使用mysqli\uxxxx\uxxxx…
。Ref:实现这一点的简单方法是向服务器脚本发出ajax请求,从数据库中提取数据,然后使用jqgrid格式化相同的输出,您可以在jqgrid上搜索以了解使用它的语法。对于jqueryajaxrefere,您好,我正在处理XML数据,所以我认为这就是上面的代码不起作用的原因。是否有任何方法可以修改上面的代码以适合XML用途。显然,这是我需要的,因为我想把这两个部分分成不同的逻辑,但我只是不知道如何执行cos,正如我说的,我是Jqgrid的新手。再次感谢。我已经为您编辑了我的原始代码,以查看我的数据是如何处理的。我仍在深入研究代码,看看是否能让它工作。好的,现在我将所有数据转换成JSON格式。还是一样的问题高级搜索不起作用。今晚晚些时候我会查出来。你能发布你的jqgrid代码(前端的东西)吗?谢谢新年快乐!
