问题描述
Hello Team，
我有以下实体框架。
在DataManger.cs
我有如下代码。
public IEntityBase GetQCCount（IEntityBase entityBase）
{
IDataReader dataReader = null;
IQCAllocation qcallocation = null;
try
{
Logger.Write（Inside QBpoDataManager.GetQCCount（），LogType.Information）;
qcallocation = entityBase as IQCAllocation;
string query =select count（ID）as Customerloandata with Count（nolock），其中qcuserid =+ qcallocation.AllocateToQC +AND isnull（QCPROCESSED，0）= 0 AND isnull（QCTOVERIFY，0 ）= 1和isnull（删除，0）= 0和STATE ='+ qcallocation.State +'和batchid =+ qcallocation.BatchId +;
CommonDataAccess.CreateSqlStringCommandWrapper（string.Format（query））;
dataReader = CommonDataAccess.ExecuteReader（）;
while（dataReader.Read（））
{
qcallocation = QBpoEntityCreator.GetQCAllocationEntity（）;
qcallocation.Count = dataReader [QBpoConstants.COUNT] .ObjectToInt32（）;
}
Logger.Write（退出QBpoDataManager.GetQCCount（），LogType.Information）;
}
catch（异常异常）
{
抛出异常;
}
最后
{
dataReader.CloseDataReader（）;
}
返回qcallocation;
}
In（BusinessManager）QbpoManager.cs
我的代码如下：
public Result GetQCCount（IEntityBase entityBase）
{
结果result = null;
try
{
result = new Result（）;
Logger.Write（Inside DashboardManagerRead.GetQCCount（），LogType.Information）;
QBpoDataManager qbpoDataManager = new QBpoDataManager（）;
result.Entity = qbpoDataManager.GetQCCount（entityBase）;
Logger.Write（Exiting DashboardManagerRead.GetQCCount（），LogType.Information）;
}
catch（异常异常）
{
exception.HandleException（Global.CONSTSTREXCPOLICYBUSINESS）;
}
返回结果;
}
在UI Controller.cs
我的代码如下：
public Result GetQCCount（IEntityBase entityBase）
{
结果result = null;
if（this.qbpoManager！= null）
{
result = this.qbpoManager.GetQCCount（entityBase）;
}
返回结果;
}
在QCAllocationASPX.cs
我的代码如下：
[WebMethod]
public static string GetQCCount（object allocateQCCountDetails ）
{
string resultMessage = string.Empty;
结果result = null;
IQCAllocation qcallocation = QBpoEntityCreator.GetQCAllocationEntity（）;
尝试
{
qcallocation = allocateQCCountDetails.ConvertToJsonString（）。JsonToObject（qcallocation.GetType（））as IQCAllocation;
DisplayDEOIDCount = QbpController.GetQCCount（qcallocation）.Entity.ConvertToJsonString（）;
if（result！= null&& result.Error.GetCount（）> 0）
{
resultMessage = result.Error.GetAll（）;
}
}
catch（异常异常）
{
resultMessage = string.Format（技术错误发生。{0}。请联系系统管理员。，exception.Message）;
}
返回DisplayDEOIDCount;
}
在QcAllocation.ASPX页面
我写了Jquery如下：
< td>
< label id =allocateToQCCountLabel>
QC数量：
< / label>
< / td>
var GetQCCount;
函数allocateQCEntity（）{
var allocateQC = cloneObject（blankQCAllocationEntity）;
allocateQC.TopCountForQC = $（'＃topCountForQCTextbox'）。val（）;
allocateQC.AllocateToQC = $（＃allocateToSelect option：selected）。val（）;
返回allocateQC;
}
函数GetCountForQCQC（）{
debugger;
var qcCountEntity = allocateQCEntity（）;
$ .ajax（{
url：'QCAllocation.aspx / AllocateToQC'，
类型：'POST'，
contentType：'application / json; charset = utf-8' ，
dataType：json，
data：'{allocateQCCountDetails：'+ JSON.stringify（qcCountEntity）+'}'，
成功：函数（结果）{
调试器;
if（result.d！=''）{
GetQCCount = JSON.parse（result.d）;
$（'＃allocateToQCCountLabel'）。text（GetQCCount .Count ）.val（GetQCCount .Count）;
}
}，
错误：函数（错误）{
manageOverlay（false）;
alert（ error.responseText）;
}，
async：false
}）;
};
不要担心这段代码，因为这段代码对我有用。
我想为
执行一项任务< td>
< select id =allocateToSelectclass =combo150>
< / select>
< / td>
在Dropdown中我得到的值为：DEO1
DE02
DE03
在更改事件时，如果我选择其中一个来自DropDown的id，我想要特定用户的QCCount即（DE01，DE02，DE03）。
如何在Change Function Jquery上获取它。
请指导我。
谢谢

Hello Team,
I have the Entity Framework as follows.
In DataManger.cs
I have the code as follow.
public IEntityBase GetQCCount(IEntityBase entityBase)
{
IDataReader dataReader = null;
IQCAllocation qcallocation = null;
try
{
Logger.Write("Inside QBpoDataManager.GetQCCount()", LogType.Information);
qcallocation = entityBase as IQCAllocation;
string query = "select count(ID) as Count from Customerloandata with (nolock) where qcuserid = " + qcallocation.AllocateToQC + " AND isnull(QCPROCESSED,0) = 0 AND isnull(QCTOVERIFY,0) = 1 and isnull(deleted,0) = 0 and STATE = '" + qcallocation.State + "' and batchid = " + qcallocation.BatchId + " ";
CommonDataAccess.CreateSqlStringCommandWrapper(string.Format(query));
dataReader = CommonDataAccess.ExecuteReader();
while (dataReader.Read())
{
qcallocation = QBpoEntityCreator.GetQCAllocationEntity();
qcallocation.Count = dataReader[QBpoConstants.COUNT].ObjectToInt32();
}
Logger.Write("Exiting QBpoDataManager.GetQCCount()", LogType.Information);
}
catch (Exception exception)
{
throw exception;
}
finally
{
dataReader.CloseDataReader();
}
return qcallocation;
}
In (BusinessManager)QbpoManager.cs
I have the code as follow:
public Result GetQCCount(IEntityBase entityBase)
{
Result result = null;
try
{
result = new Result();
Logger.Write("Inside DashboardManagerRead.GetQCCount()", LogType.Information);
QBpoDataManager qbpoDataManager = new QBpoDataManager();
result.Entity = qbpoDataManager.GetQCCount(entityBase);
Logger.Write("Exiting DashboardManagerRead.GetQCCount()", LogType.Information);
}
catch (Exception exception)
{
exception.HandleException(Global.CONSTSTREXCPOLICYBUSINESS);
}
return result;
}
In UI Controller.cs
I have the code as follows:
public Result GetQCCount(IEntityBase entityBase)
{
Result result = null;
if (this.qbpoManager != null)
{
result = this.qbpoManager.GetQCCount(entityBase);
}
return result;
}
In QCAllocationASPX.cs
I have the code as follows:
[WebMethod]
public static string GetQCCount(object allocateQCCountDetails)
{
string resultMessage = string.Empty;
Result result = null;
IQCAllocation qcallocation = QBpoEntityCreator.GetQCAllocationEntity();
try
{
qcallocation = allocateQCCountDetails.ConvertToJsonString().JsonToObject(qcallocation.GetType()) as IQCAllocation;
DisplayDEOIDCount = QbpController.GetQCCount(qcallocation).Entity.ConvertToJsonString();
if (result != null && result.Error.GetCount() > 0)
{
resultMessage = result.Error.GetAll();
}
}
catch (Exception exception)
{
resultMessage = string.Format("Technical error ocurred. {0}. Please contact to system administrator.", exception.Message);
}
return DisplayDEOIDCount;
}
In QcAllocation.ASPX page
I have written the Jquery as follows:
<td>
<label id="allocateToQCCountLabel">
QC Count :
</label>
</td>
var GetQCCount ;
function allocateQCEntity() {
var allocateQC = cloneObject(blankQCAllocationEntity);
allocateQC.TopCountForQC = $('#topCountForQCTextbox').val();
allocateQC.AllocateToQC = $("#allocateToSelect option:selected").val();
return allocateQC;
}
function GetCountForQCQC() {
debugger;
var qcCountEntity = allocateQCEntity();
$.ajax({
url: 'QCAllocation.aspx/AllocateToQC',
type: 'POST',
contentType: 'application/json; charset=utf-8',
dataType: "json",
data: '{"allocateQCCountDetails":' + JSON.stringify(qcCountEntity) + '}',
success: function (result) {
debugger;
if (result.d != '') {
GetQCCount = JSON.parse(result.d);
$('#allocateToQCCountLabel').text(GetQCCount .Count).val(GetQCCount .Count);
}
},
error: function (error) {
manageOverlay(false);
alert(error.responseText);
},
async: false
});
};
Dont get worry for this code ,as this code is working for me.
I want to perform one task for
<td>
<select id="allocateToSelect" class="combo150">
</select>
</td>
In Dropdown i am getting the Value as:DEO1
DE02
DE03
On change Event,if i select one of the id from DropDown, i want QCCount for particular User ie (DE01,DE02,DE03).
How to get it on Change Function Jquery.
Please guide me .
Thanks
