Question

我想在剃刀视图中创建一个表。

<div class="row" style="margin-left:80%">
    @if (ViewBag.IsGlobal == 1)
    {
        <script>
            $(document).ready(function () {
                $("#btnViewLocal").prop("disabled",true);

                @foreach (var item in Model.GlobalNewsModel)
                {

                    var gTable = "<tr class=\"tvl\">";
                    gTable += "<td>";
                    gTable += "<input id=\"testid\" value=\"testvalue\" class=\"form-control\" />";
                    gTable += "<td>";
                    gTable += "</tr>";
                    //gTable.append("#wholeNews tr:last").after(gTable); <-- I tried it like this it also not working.
                }
                $("#WholeNews tr:last").after(gTable); // I can't place thisone inside foreach loop,it's unrecognize the $
            });
        </script>
    }
}
</div>

然后

我在没有foreach循环的情况下对该表进行了硬编码并且它正在工作。但是我的要求是将其放在foreach循环中。为了您的参考，我已经把它放在这里。

var gTable = "<tr class=\"tvl\">";
gTable += "<td>";
gTable += '<input id="' + $(this).closest('tr').find('td :eq(0)').val() + "newsno" + '" disabled type="text\" class=\"form-control" value="' + $(this).closest('tr').find('td :eq(0)').val() + '">';
gTable += "</td>";
gTable += "</tr>";
$("#WholeNews tr:last").after(gTable);

如何在客户端上创建循环：

@if (ViewBag.IsGlobal == 1)
{
    <script>
        $(document).ready(function () {
            $("#btnViewLocal").prop("disabled", true);

            // serialize the server side model on the client
            var news = @Html.Raw(Json.Encode(Model.GlobalNewsModel));

            // loop through the news javascript variable on the client
            for (var i = 0; i < news.length; i++) {
                // here you can access news[i] if you need to print
                // some values from your model in the table

                var gTable = "<tr class=\"tvl\">";
                gTable += "<td>";
                gTable += "<input id=\"testid\" value=\"testvalue\" class=\"form-control\" />";
                gTable += "<td>";
                gTable += "</tr>";
                gTable.append("#wholeNews tr:last").after(gTable);
            }
        }
    </script>
}

另请注意，如果您不需要访问客户端上的news[i]，那么您可能不需要序列化您的模型，只需要长度：

var newsLength = @Model.GlobalNewsModel.Length;
for (var i = 0; i < newsLength; i++) {
    ...
}

但我想你需要模型值。另请注意，您只能在客户端上投影您真正需要的值，以避免在标记中浪费不必要的空间：

var news = @Html.Raw(Json.Encode(Model.GlobalNewsModel.Select(x => new
{
    foo = x.Foo,
    bar = x.Bar,
})));
for (var i = 0; i < news.length; i++) {
    // you can access news[i].foo and news[i].bar here
    ...
}

在razor视图中使用jquery创建一个表
