问题描述

我一直试图让这个工作好几天,这似乎是一件接一件的事情.最初,我终于找到了将 JSON 字符串中的 ASP.NET 日期传递回网格的麻烦.我现在正在使用 JSON.NET,日期又回到了应有的状态,我被困在了我似乎一直在的地方.这是我的代码,返回的 json 字符串和 jqGrid 代码:(很抱歉它太长了,但我只是不想遗漏任何东西,以防那部分让我搞砸了)!基本上,我一直被困在我尝试添加JSONData的ajax调用的成功方法中......截至目前,我从Firebug收到一个错误,上面写着:无效的属性 ID({total:1,page:1,records:5,[{"ROWID":1,"...rName":"BCC","SubmitterID":"BCC4010","Su

I've been trying to get this to work for days upon days and it seems like one thing after another. Initially, I finally tracked it down to trouble passing ASP.NET dates in the JSON string back to the grid. I am now using JSON.NET and the dates are coming back the way they should be I'm stuck right back where I alwasy seem to be. Here is my code, returned json string, and jqGrid code also: (I'm sorry it's so long, but I just didn't want to leave anything out in case that was the part that was screwing me up)! Basically, I am continually stuck in the success method of the ajax call where I try to addJSONData.... as of right now I am getting an error from Firebug that says: invalid property id ({total:1,page:1,records:5,[{"ROWID":1,"...rName":"BCC","SubmitterID":"BCC4010","Su

我们将不胜感激任何帮助!我非常想使用这个插件,但我绝对要让它工作起来!

ANY HELP WOULD BE SO GREATLY APPRECIATED! I Want to use this plug in so much, but I am going absolutely nuts trying to make it work!

在此先感谢,Briana :-)

Thanks in Advance, Briana :-)

实际上,tvanfosson 对行"标识符的要求提出了一个很好的观点.我对 jMSAjax 不熟悉,所以我的评论可能无效.我很高兴知道这一点.

Actually, tvanfosson makes an excellent point with the requirement of the 'rows' identifier. I'm unfamiliar with jMSAjax so my comments may be null and void. I'm glad to be aware of it.

它可以像返回类型是字符串一样简单吗?也就是说,在评估响应时,您最终会得到封装的字符串而不是 json 对象.

Could it be something as simple as the return type being string? That is, when the response is evaluated, you end up with the encapsulated string not the json object.

我自己也去过类似的地方.我发现选项是,创建一个表示预期 jqGrid 响应的业务对象并返回该对象而不是字符串(ASP.NET 将为您将其序列化为 JSON!)或将 jqGrid 修改为 eval 响应两次(混乱).

I've been in a similar place myself. I found the options to be either, create a business object that represents the expected jqGrid response and return the object not a string (ASP.NET will serialize it as JSON for you!) or modify the jqGrid to eval the response twice (messy).
