Question

我有一个我无法处理的问题。我有一个ASP.NET MVC应用程序。它的目的是在里面列出物品。这些项目是项目活动及其财务报告。在视图中，用户假设查看项目活动的财务信息并编辑某些值。以下是观点：

如上所述，javascript函数 readTender 需要 projectActivityId 作为读取投标信息的输入。我将 projectActivityId 写入视图的最后一个td标记。如何将 projectActivityId 传递给 readTender （）？

以下是 ProjectActivityFinancialReportViewModel 的内容：

@model IEnumerable<DKMPPIB.Presentation.ViewModelKlasor.VarlikKlasoru.ProjectActivityFinancialReportViewModel>

<table class="table">
    <tr>
        <th>
            @Html.DisplayNameFor(model => model.Region)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.City)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.ProjectName)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.FieldName)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.ProjectActivityName)
        </th>           
        <th></th>
    </tr>

    @foreach (var item in Model)
    {
        <tr>     
            <td>
                @Html.DisplayFor(modelItem => item.Region)
            </td>      
            <td>
                @Html.DisplayFor(modelItem => item.City)
            </td> 
            <td>
                @Html.DisplayFor(modelItem => item.ProjectName)
            </td>
            <td>
                @Html.DisplayFor(modelItem => item.FieldName)
            </td>
            <td>
                @Html.DisplayFor(modelItem => item.ProjectActivityName)
            </td>            
            <td>
                <a onclick="readTender()" >
                    <img src='@Url.Content("~/Content/Images/glyphicons_free/glyphicons-342-briefcase.png")' />
                </a>                    
            </td>
            <td>
                <a href='@Url.Action("MyAction", "MyController")'>
                    <img src='@Url.Content("~/Content/Images/glyphicons_free/glyphicons-459-money.png")' />
                </a>
            </td>    
            @*Take attention to that line. I embed the ProjectActivityId here.*@                
            <td style="visibility:hidden" id="satirProjeFaaliyetId">@Html.DisplayFor(modelItem => item.ProjectActivityId)</td> 

        </tr>        
    }

</table>

<script type="text/javascript">


    function readTender(){

    //I will make an ajax call to get tender information. I need ProjectActivityId for this.
        alert("read tender");
        //var projectActivityId = $('#ProjectActivityId').find(":selected").val();
        //console.log(bolgeDropdownId);

        //$.ajax({
        //    type: "POST",

    }

</script>

Answer 1

<td style="visibility:hidden" id="satirProjeFaaliyetId">@Html.DisplayFor(modelItem => item.ProjectActivityId)</td>

问题在于，您尝试按不存在的ID查找元素：

$('#ProjectActivityId').find(":selected").val();

所以将顶行更改为以下内容：

<td style="visibility:hidden;" id="ProjectActivityId">@item.ProjectActivityId</td>

和js-code中的行

$('#ProjectActivityId').val();

Answer 2

您可以处理每行的点击事件。我想“选择”是通过行上的“点击”来处理的。你可以这样做：

更改您的javascript功能：

function readTender(projectActivityId) { ... }

在foreach中更改你的tr：

<tr onclick="javascript:readTender(@item.ProjectActivityId)">; ... <tr>

将参数传递给mvc中的ajax的Javascript函数
