推荐答案

隐藏字段可以在视图中创建，但您无法直接在控制器中访问它们，因此您需要从客户端传递它们作为参数



样本：

Hidden fields can create in view, but you can't access them in the controller directly, so you need to pass them as a parameter from client side

Sample:

<input type="hidden" id="txt1" value="@objPI.Id" />
                       <input type="hidden" id="txt1" value="@objPI.Version" />
                       <input type="hidden" id="txt2" value="@objPI.FileLocationId" />

现在这些值可以传递给控制器​​

Now these values can be passed to controller as

function VP_GetDesign() {
    try {

        VP_ShowLoading("Show");
        //debugger;
        var vP1 = jQuery.trim(document.getElementById("txt1").value);
        var vP2 = jQuery.trim(document.getElementById("txt2").value);
       

        var d = {
            vP1: vP1,
            vP2: vP2,
            
        }


        AjaxPost('/ViewPlace/GetDesign', d, 'VP_GetDesign_CallBack', 'VP_AjaxError');     // your post method 
    }
    catch (err) {
        VP_ShowLoading("Hide");
        alert(err);
    }
}

控制器代码看起来像这样

The controller code look's like this

public ActionResult GetDesign(String vP1, String vP2)
       {
           try
           {
               //vP1=version; vP2=filelocation
           }
         catch(Exception ex)
         {
       throw ex;
         }
       }

检查隐藏字段是否在表单元素中。

Check whether hidden field is in form element.

这是非常简单的解决方案。

Here is very simple solution for that.

<div style="padding-left:20px" class="pull-left">
@{
	if (TempData["BasketTrnId"] != null)
	{
	    var BasketTrnId = TempData["BasketTrnId"].ToString();
	    <input type="hidden" id="BasketRefNo" value="@BasketTrnId" data-bind="text: hiddnBasketRefNumber"/>
	}
	else
	{
	   <input type="hidden" id="BasketRefNo" value="" data-bind="text: hiddnBasketRefNumber" />
	}
}
</div>
