我有一个带有工具栏（navGrid）的简单jQgrid，用于添加，编辑，删除和搜索。问题是搜索不起作用。它似乎总是从表中返回所有记录而不是一个，这意味着where子句有问题，我试图根据搜索模式窗口中给出的内容生成。或者可能根本没有激活搜索案例..
这是网格代码：
$("#list").jqGrid({
url: "server.php",
datatype: "json",
mtype: "POST",
colNames: ["Driver ID", "Name", "Country", "Victories", "Poles",
"Titles", "Fastest laps"], //"Team name"],
colModel: [
{ name: "driverid", index:"driverid", width: 55, search:true, stype:'text', editable:false},
{ name: "name", index:"name", width: 90, search:true, stype:'text', editable:true },
{ name: "country", index:"country", width: 90, search:true, stype:'text', editable:true },
{ name: "victories", index:"victories", width: 80, search:true, align: "right", editable:true },
{ name: "poles", index:"poles", width: 80, search:true, align: "right", editable:true },
{ name: "titles", index:"titles", width: 80, search:true, align: "right", editable:true },
{ name: "flaps", index:"flaps", width: 80, search:true, align: "right", editable:true}
//{ name: "teamName", width: 80, align: "right", editable:true}
],
autowidth: true,
pager: "#pager",
rowNum: 10,
rowList: [10, 20, 30],
sortname: "driverid",
sortorder: "asc",
viewrecords: true,
gridview: true,
autoencode: true,
caption: "F1 statistics grid",
editurl: "dbedit.php"
});
jQuery("#list").jqGrid('navGrid','#pager',{add:true,del:true,edit:true,search:true});
});
以下是dbedit.php中的部分：

我已经完成了20次代码，看看我输错了什么，我看不到它。当我定义网格或colModel时，我错过了什么？
答案 0 :(得分：0)
我已经失去了很多时间试图解决这个问题。最后，我在网格代码中放置了loadonce：true并且它有效。所以，试试吧。把它放在任何地方，例如：viewrecords：true
