我有一个jgrid设置并正确显示数据。我添加了一个filtertoolbox但是当我输入内容时，网格没有显示任何数据。如果我使用放大镜进行搜索，一切都按预期工作。
这是代码： 的index.html

答案 0 :(得分：1)
您使用stringResult: false选项。它表示另一种格式数据，作为您当前使用的single field searching格式。您可以尝试使用Fiddler或Firebug或IE或Chrome的开发人员工具来捕获HTTP流量。您会看到，在stringResult: false选项的情况下，jqGrid会以
key=value
key是应用过滤器的列的index或name属性的值。例如，如果用户在notes列之上的输入字段中键入文本“bla”而不是参数
notes=bla
将在网址中找到。您可以使用$_REQUEST['notes']来获取它。
由于单字段搜索的数据格式与stringResult: false的格式不同，我个人更喜欢使用与高级搜索格式相同的stringResult: true格式，请参阅the documentation。
