将HTML表发布到ADO.NET DataTable

有一个 HTML 表如下:

<table id="tblCurrentYear">
    <tr>
        <td>Leave Type</td>
        <td>Leave Taken</td>
        <td>Leave Balance</td>
        <td>Leave Total</td>
    </tr>
    @foreach (var item in Model.LeaveDetailsList)
    {
        <tr>
            <td>@Html.TextBoxFor(m => item.LeaveType, new { width = "100" })</td>
            <td>@Html.TextBoxFor(m => item.LeaveTaken, new { width = "100" })</td>
            <td>@Html.TextBoxFor(m => item.LeaveBalance, new { width = "100" })</td>
            <td>@Html.TextBoxFor(m => item.LeaveTotal, new { width = "100" })</td>
        </tr>
    }</table>

我想遍历所有的 html 表行，并在 ADO.NET DataTable 中插入值。
简单地说，将 HTML Table 转换为 ADO.NET DataTable。
如何从 HTML 表中提取值并插入到 ADO.NET DataTable中？
该view基于以下模型

public class LeaveBalanceViewModel{
    public LeaveBalanceViewModel()
    {
        this.EmployeeDetail = new EmployeeDetails();
        this.LeaveBalanceDetail = new LeaveBalanceDetails();
        this.LeaveDetailsList = new List<LeaveBalanceDetails>();
    }
    public EmployeeDetails EmployeeDetail { get; set; }
    public LeaveBalanceDetails LeaveBalanceDetail { get; set; }
    public List<LeaveBalanceDetails> LeaveDetailsList { get; set; }}

为了绑定到发回来的模型，表单控件的 name 属性必须匹配模型属性。使用 foreach 循环不会生成正确的 name 属性。如果你检查 html，会看到这个

但是为了绑定到你的模型，control 要

反正就是这样子之类的。考虑这个问题的最简单方法是考虑如何在 c # 代码中访问 LeaveType 属性的值

var model = new LeaveBalanceViewModel();// add some LeaveBalanceDetails instances to the LeaveDetailsList property, then access a valuevar leaveType = model.LeaveDetailsList[0].LeaveType;

因为您的 POST 将有一个参数名(比如model) ，所以只需删除前缀(model) ，这就是控件的 name 属性必须的样子。 为此，必须使用forloop (集合必应用IList)

for(int i = 0; i < Model.LeaveDetailsList.Count; i++){
    @Html.TextBoxFor(m => m.LeaveDetailsList[i].LeaveType)
    ....}

或使用自定义 EditorTemplate (集合只需实现 IEnumerable)
在/Views/Shared/EditorTemplates/LeaveBalanceDetails.cshtml

@model yourAssembly.LeaveBalanceDetails<tr>
    <td>@Html.TextBoxFor(m => m.LeaveType)</td>
    ....</tr>

然后在主视图中(不是在循环中)

<table>
    .... // add headings (preferably in a thead element
    <tbody>
        @Html.EditorFor(m => m.LeaveDetailsList)
    </tbody></table>

最后，在控制器里

public ActionResult Edit(LeaveBalanceViewModel model){
    // iterate over model.LeaveDetailsList and save the items}

试试这个

jQuery(document).on("change", ".DDLChoices", function (e) {
    var comma_ChoiceIds = '';
    var comma_ChoicesText = '';
    $('input[class="DDLChoices"]').each(function (e) {
        if (this.checked) {
            comma_ChoiceIds = comma_ChoiceIds + $(this).val() + ',';
            comma_ChoicesText = comma_ChoicesText + $(this).parent('label').parent() + ',';
        }
    });
    $('#ChoiceIds').val(comma_ChoiceIds);
    $('#ChoiceText').val(comma_ChoicesText);});
@using (Html.BeginForm("Actionname", "Controllername", FormMethod.Post, new { id = "frmChoices" }))
{
    @Html.HiddenFor(m => m.ChoiceText, new { @id = "ChoiceText" })
    @Html.HiddenFor(m => m.ChoiceIds, new { @id = "ChoiceIds" })
    <div class="form-group">
        <div>
            <table>
                <tr>
                    <th>Name</th>
                    <th>Selected</th>
                </tr>
                @foreach (var item in @Model.Choices)
                {
                    <tr>
                        <td> <label>@item.ChoicesText</label>    </td>
                        <td> <input class="DDLChoices" value="@item.ChoiceIds" type="checkbox" /></td>
                    </tr>
                }
            </table>
        </div>
     <input type="button" value="Submit" onclick="return ChoicesPoster.passChoices()"
    </div>
}
