Question

我有一个视图，我得到了我的Ajax.BeginForm，它提交它应该。但后来我有一个＆＃34;保存图标＆＃34;当我按下那个按钮时，我需要表格中的值。表单提交表示计算，并且保存图标可以保存全部。

但是当我按下保存图标（使用Url.Action（＆＃34; SaveExcel＆＃34;，＆＃34;保存＆＃34;）时，我无法从文本框中获取值。我如何那样做？

我的HTML：

        <a href="@Url.Action("SaveExcel", "Save")" title="Save"><img src="../../Images/glyphicons_446_floppy_save.png" alt="save" id="saveIcon"></a>

<!-- Contains forms and input for annuity calculation -->
<div class="calcInput" id="calcInput">
@using (Ajax.BeginForm("ShowDetailAnnuity", "Calculation", new AjaxOptions
{
    InsertionMode = InsertionMode.Replace,
    UpdateTargetId = "CalcDetail",
    LoadingElementId = "Loader",
}))
{
   <div class="calculateBox">
        <label for="calcOption">Choose value to calculate:</label>
        <select id="calcOption" name="calcOption" title="Choose what value you want to calculate">
            <option value="PMT" id="PMT" name="PMT">Payment (PMT)</option>
            <option value="I" id="I" name="I">Interest (I)</option>
            <option value="FV" id="FV" name="FV">Future value (FV)</option>
            <option value="PV" id="PV" name="PV">Present value (PV)</option>
        </select>
    </div>
    <div class="calculateBox" background-color="#777777">
        @Html.Label("Present value (PV)", new { @id = "pvLabel" })
        @Html.TextBox("PresentValue", null, new { @class = "PresentValue" })
        @Html.Label("Future value (FV)", new { @id = "fvLabel" })
        @Html.TextBox("FutureValue", null, new { @class = "FutureValue" })
        @Html.Label("Interest rate", new { @id = "intRateLabel" })
        @Html.TextBox("InterestRate", null, new { @class = "InterestRate" }) <br /> <br />
        <input type="radio" name="advanceOrArrears" id="inAdvance" value="inAdvance" /> In advance<br />
        <input type="radio" name="advanceOrArrears" id="inArrears" value="inArrears" /> In arrears
    </div>
    <div class="calculateBox">
        <label for="startDate">Start date:</label>
        <input type="date" id="StartDate" name="startdate" title="Choose start date for your calculation" /><br />
        @Html.Label("Payment frequency")
        <select id="PmtFreq" name="PmtFreq" title="Choose the payment frequency, for example: Every month">
            <option value="Monthly">Monthly</option>
            <option value="Quarterly">Quarterly</option>
        </select><br /><br />
        @Html.Label("No of payment periods")
        @Html.TextBox("PaymentPeriods")
        @Html.Label("Date time convention")
        <select id="DTC" name="DTC" title="Choose your Date time convention">
            <option value="360/360">360/360</option>
            <option value="365/365">365/365</option>
        </select><br /><br />
        <input type="submit" id="CalcBtn" class="calcBtn" name="SubmitBtn" value="Calculate" title="Calculate your calculation" />
    </div>
}
</div>

我的控制器：

public class SaveController : Controller
{
    public ActionResult SaveExcel(string PresentValue) //Can't get PresentValue here..
    {

        return View();
    }
}

我尝试在控制器中使用文本框的名称作为参数，我也尝试了Request.Form [＆＃34; PresentValue＆＃34;]但是没有任何工作

听起来你需要两个提交按钮。

尝试将保存按钮转换为表单中的提交按钮，以便您拥有：

<input type="submit" name="SubmitButton" value="Calculate"/>
<input type="submit" name="SubmitButton" value="Save"/>

然后在你的控制器中，通过以下方式区分按下哪个按钮：

public ActionResult SaveExcel(string PresentValue, string SubmitButton) 
{

    if(SubmitButton == "Save") .... <save code>
    if(SubmitButton == "Calculate") .... <calc code>

    return View();
}

从MVC中的按钮单击外部表单发送文本框值
