我曾看過在所有相關的答案中發揮過的建議，但無濟於事。我嘗試了各種選擇，但再次無濟於事。我正在使用ASP.NET與C＃作爲處理語言，並使用作爲數據庫引擎的Oracle 10g。JSON數據在JQGrid中不顯示
這裏是我的.aspx文件：
<form id="LocalizationSearch" name="locSearch" defaultbutton="updateButton" runat="server">
<script language="javascript" type="text/javascript">
jQuery(document).ready(function() {
var createLanguageList = function() {
$("#list").jqGrid({
url: "KPHandler.ashx?langname=English",
datatype: "json",
contentType: "application/json; charset=utf-8",
mtype: 'POST',
//datatype: "local",
//data: mydata,
autowidth: true,
height: 150,
colNames: ['DelLanguageID', 'DocRecID', 'LanguageID', 'DocPartNumber,', 'NewLanguage', 'ConcentraIDLang', 'ActFromTranslation'],
colModel: [
{ name: 'DelLanguageID', index: 'DelLanguageID', width: 65, editable: false },
{ name: 'DocRecID', index: 'DocRecID', width: 65, editable: false },
{ name: 'LanguageID', index: 'LanguageID', width: 65, editable: false },
{ name: 'DocPartNmbr', index: 'DocPartNmbr', width: 65, editable: true },
{ name: 'NewLanguage', index: 'NewLanguage', editable: true, edittype: 'checkbox', editoptions: { value: "1:0"} },
{ name: 'ConcentraIDLang', index: 'ConcentraIDLang', width: 65, editable: true },
{ name: 'ActFromTranslation', index: 'ActFromTranslation', width: 120, editable: true }
],
rowNum: 5,
rowList: [10, 20, 30],
pager: '#pager',
sortname: 'DelLanguageID',
viewrecords: true,
//altRows: true,
//sortorder: "desc",
caption: "Deliverable Languages",
//height: "100%",
loadonce: true,
gridview: true,
autoencode: true,
loadError: function (jqXHR, textStatus, errorThrown) {
alert('Error: ' + textStatus + errorThrown + jqXHR.responseText);
}
}); // JQGrid
}; // Create function
$("#btnLanguages").click(function() {
createLanguageList();
});
}); // document ready
</script>
<table cellspacing="1" cellpadding="0" width="100%">
<tr>
<td valign="top">
<table id="list"></table>
<div id="pager"></div>
</td>
</tr>
</table>
<input type="button" id="btnLanguages" value="Work With Languages" />
</form>
，這裏是我的C＃代碼，構建JSON對象：我
<%@ WebHandler Language="C#" Class="KPHandler" %>
using System;
using System.Web;
using System.Web.Script.Serialization;
using System.Web.Configuration;
using System.Text;
using System.Data;
using System.Collections.Generic;
using System.Configuration;
using System.Data.OracleClient;
public class KPHandler : IHttpHandler
{
private DKCL.ReportDK Rpt = new DKCL.ReportDK();
public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "application/json";
System.Collections.Specialized.NameValueCollection forms = context.Request.Form;
string strOperation = forms.Get("oper");
switch (strOperation)
{
case null: // means this is the first time load
string strSQL = "SELECT DelLanguageID, DocRecID, LanguageID, DocPartNmbr, NewLanguage, " +
"ConcentraIDLang, ActFromTranslation FROM DELLANGUAGES WHERE DOCRECID = 18787";
DataTable dlLanguages = Rpt.GetDataTable(strSQL);
context.Response.Write(GetJson(dlLanguages));
break;
default:
break;
} // End Switch
}
// This is generic function that converts DataTable into JSON object.
public string GetJson(DataTable dt)
{
System.Web.Script.Serialization.JavaScriptSerializer serializer = new
System.Web.Script.Serialization.JavaScriptSerializer();
List<Dictionary<string, object>> rows =
new List<Dictionary<string, object>>();
Dictionary<string, object> row = null;
foreach (DataRow dr in dt.Rows)
{
row = new Dictionary<string, object>();
foreach (DataColumn col in dt.Columns)
{
row.Add(col.ColumnName.Trim(), dr[col]);
}
rows.Add(row);
}
return serializer.Serialize(rows);
}
public bool IsReusable
{
get
{
return false;
}
}
}
，這裏是由上面的代碼返回的JSON數據（其實得到這個如圖Fiddler2），和我自己的調試代碼：
[{"DELLANGUAGEID":"4613","DOCRECID":"18787","LANGUAGEID":"12","DOCPARTNMBR":null,"NEWLANGUAGE":0,"CONCENTRAIDLANG":"c02609839","ACTFROMTRANSLATION":null},{"DELLANGUAGEID":"4614","DOCRECID":"18787","LANGUAGEID":"34","DOCPARTNMBR":null,"NEWLANGUAGE":0,"CONCENTRAIDLANG":null,"ACTFROMTRANSLATION":null},{"DELLANGUAGEID":"4615","DOCRECID":"18787","LANGUAGEID":"1","DOCPARTNMBR":null,"NEWLANGUAGE":0,"CONCENTRAIDLANG":"c02606925","ACTFROMTRANSLATION":null},{"DELLANGUAGEID":"4616","DOCRECID":"18787","LANGUAGEID":"13","DOCPARTNMBR":null,"NEWLANGUAGE":0,"CONCENTRAIDLANG":"c02609850","ACTFROMTRANSLATION":null},{"DELLANGUAGEID":"4617","DOCRECID":"18787","LANGUAGEID":"11","DOCPARTNMBR":null,"NEWLANGUAGE":0,"CONCENTRAIDLANG":"c02606924","ACTFROMTRANSLATION":null},{"DELLANGUAGEID":"4618","DOCRECID":"18787","LANGUAGEID":"3","DOCPARTNMBR":null,"NEWLANGUAGE":0,"CONCENTRAIDLANG":"c02606920","ACTFROMTRANSLATION":null},{"DELLANGUAGEID":"4619","DOCRECID":"18787","LANGUAGEID":"21","DOCPARTNMBR":null,"NEWLANGUAGE":0,"CONCENTRAIDLANG":null,"ACTFROMTRANSLATION":null},{"DELLANGUAGEID":"39703","DOCRECID":"18787","LANGUAGEID":"142","DOCPARTNMBR":"593957-001","NEWLANGUAGE":0,"CONCENTRAIDLANG":null,"ACTFROMTRANSLATION":null},{"DELLANGUAGEID":"89446","DOCRECID":"18787","LANGUAGEID":"161","DOCPARTNMBR":null,"NEWLANGUAGE":0,"CONCENTRAIDLANG":null,"ACTFROMTRANSLATION":null},{"DELLANGUAGEID":"97174","DOCRECID":"18787","LANGUAGEID":"162","DOCPARTNMBR":null,"NEWLANGUAGE":0,"CONCENTRAIDLANG":null,"ACTFROMTRANSLATION":null},{"DELLANGUAGEID":"112630","DOCRECID":"18787","LANGUAGEID":"164","DOCPARTNMBR":null,"NEWLANGUAGE":0,"CONCENTRAIDLANG":null,"ACTFROMTRANSLATION":null},{"DELLANGUAGEID":"104902","DOCRECID":"18787","LANGUAGEID":"163","DOCPARTNMBR":null,"NEWLANGUAGE":0,"CONCENTRAIDLANG":null,"ACTFROMTRANSLATION":null}]
任何想法，可能是印度政府恩錯了嗎？ 網格顯示正確的記錄數和頁面中的頁面。任何幫助將不勝感激。
順便說一下，我嘗試了GET vs POST，json vs jsonstring等以及許多其他選項，包括JSON Reader，但沒有運氣。
這是不完全清楚你在問什麼。你是否說網格顯示的行數等於返回的數據量，但不是實際的數據值？ – Strake 2014-10-06 21:23:44
