我有一个主视图和两个部分视图.我需要能够使用我的第一个局部视图中的值填充viewmodel,并在单击按钮时将viewmodel传递给第二个局部视图.该按钮位于第二个局部视图中.我已经写了一个javascript函数来做这个,但是当我检查控制器方法时,viewmodel是空的.正如您在下面的屏幕截图中看到的那样,服务框是第二个局部视图

第一部分视图

第二部分观点

@model CC.GRP.MCRequest.ViewModels.NewRequestViewModel

<div id="NewRequest">
    <h1>Services</h1>

    @using (Html.BeginForm())
    {

        @Html.LabelFor(model => model.ProjectName, htmlAttributes: new { @class = "control-label col-md-5" })
        @Html.EditorFor(model => model.ProjectName, new { htmlAttributes = new { @class = "form-control", style = "width:100%" } })

        <input type="submit" value="Save" class="btn btn-default" onclick="mapInit()" />
    }


</div>


<script type="text/javascript">

    function mapInit() {
        $.ajax({
            url: '@Url.Action("Service", "request")',
            // datatype: "json",
            data: $('form').serialize(), // update this
            type: "POST",
            // contentType: 'application/json; charset=utf-8'
        });
    }


</script>

我正在创建一个SSIS包，并在提取数据时收到以下错误。

错误：分配给变量“ User :: dunsId”的值（DBNull）的类型与当前变量类型（字符串）不同。变量在执行期间可能不会更改类型。变量类型是严格的，但对象类型的变量除外。

dunsId在源表中是varchar（150），该表是可为空的列，并且包含Null值。我在SSIS中创建的用于映射它的变量是string类型。我基本上是试图提取他所有的记录，并将其插入到包含dunsId列的目标表中，该表为varchar（150）

这是我的插入查询

INSERT INTO Parties (companyId, dunsId, companyName, companyTypeId,companyTypeName,companyStatusTypeId,companyStatusTypeName,simpleIndustryId,simpleIndustryDescription)  
values (companyId, dunsId, companyName, companyTypeId, companyTypeName,companyStatusTypeId,companyStatusTypeName,simpleIndustryId,simpleIndustryDescription)

我编写了一个与子查询相当的内连接.有人能让我知道这是否是正确的做事方式,以及它是否更有效.ON关键字的过滤方式与where子句的过滤方式相同吗？

子查询

select 
        companyId,
        fiscalYear,
        fiscalQuarter,
        periodenddate
    into #PeriodTbl
    from(   
        select
            fp.companyId,
            fp.fiscalYear,
            fp.fiscalQuarter,
            fi.periodenddate,
            ROW_NUMBER() OVER (PARTITION BY fp.companyId, fp.fiscalYear, fp.fiscalQuarter ORDER BY fi.periodEndDate DESC) rowno
        from ciqfinperiod fp 
            join ciqfininstance fi on fi.financialperiodid = fp.financialperiodid
        where fp.periodtypeid = 4
            and fi.periodenddate > @date
            and fi.latestforfinancialperiodflag = 1
            and latestfilingforinstanceflag = 1 
            and fp.companyId in (select id from #companyId)

        ) a
    where a.rowno = 1

内部联接

select 
        companyId,
        fiscalYear,
        fiscalQuarter,
        periodenddate
    into #PeriodTbl

我目前正在我的 SSIS 包中实现错误发送电子邮件通知。目前它有效。只是想检查一下这是否是正确的做法。

我正在将我的 Angular 4 应用程序升级到 Angular 6 应用程序。我在构建应用程序时收到以下错误。

error TS18003: No inputs were found in config file 'tsconfig.json'. Specified 'include' paths were '["../../node_modules/@wtw/**/*"]' and 'exclude' paths were '["**/*.sp
ec.ts","**/*.stub.ts","test/**/*.ts"]'.

如果我将“**/*”添加到包含中，则会出现以下错误，并且上述错误消失。

我需要在angular 7应用程序中实现一个表，该表将按列而不是按行显示记录，如下面的屏幕快照所示。到目前为止，它一直是数据显示在网格中，但这次却有所不同。

例如，在屏幕快照Class Id的下面第一行中-值来自FundClassDetailsViewModel数组的Id字段。因此，基本上传递给组件的对象的结构是FundClassViewModel-> FundDetailsViewModel-> FundClassDetailsViewModel

FundClassDetailsViewModel包含Id，Description等

我将如何水平显示这些值

我尝试了以下建议，但看不到打印的值。循环有问题吗

有人可以教我一个例子吗

这里的字段如下

Class Id - TextBox
Legal Fund Class - Dropdownlist
Inception Date - Datetime picker
Invested Amount - Text box
Vehicle Type - Dropdownlist
Closure Status - Dropdownlist
Is Side Pocket - Checkbox
Is Thematic - Checkbox
Cogency Class - Dropdownlist

列将取决于记录数，因此需要考虑分页。

这就是JSON的结构

实际的JSON

我在本地安装了最新版本的angular-cli，并尝试使用命令ng new ETG.WEB.UI --style = scss创建一个新项目。

我收到错误消息项目名称ETG.WEB.UI无效。如果我使用命令ng new ETG --style = scss，它将成功运行

有人可以告诉我，是否真的不是按照angular-cli许可表命名约定，或者一旦创建该项目，我就将项目从ETG重命名为ETG.WEB.UI。

我的angular 7应用程序出现性能问题。我正在使用angular 7作为客户端和c＃。asp.net.webapi作为服务器代码。我注意到对webapi端点进行了两次调用，不确定为什么？我注意到的另一件事是，它最初显示7秒，之后显示1.7或1.8秒。为什么这样做
