问题描述

我收到错误Mobjlineitem未定义



< tbody data-bind =foreach:MobjLineitems> 
< tr>
< td>
< input data-bind =@ Html.DataBinding(m => m.MobjLineitems,it => it.MobjLineitem.productid)type =textvalue =/>
< / td>
< td class =number>
< input data-bind =@ Html.DataBinding(m => m.MobjLineitems,it => it.MobjLineitem.rate)type =textvalue =class =number pure -input-2-3/>
< / td>
< td class =number>
< input data-bind =@ Html.DataBinding(m => m.MobjLineitems,it => it.MobjLineitem.quantity)type =textvalue =class =number pure -input-2-3/>
< / td>
< td class =number>
< input data-bind =value:Valuereadonly =readonlytype =textvalue =class =number pure-input-2-3/>
< / td>
< td>

< input type =buttonclass =pure-buttondata-bind =click:$ parent.delItemvalue =delete/>

< / td>
< / tr>
< / tbody>





我使用如下助手



  public   static   string  DataBinding< TModel,U,V>( HtmlHelper< TModel>助手,表达式< Func< TModel,IEnumerable >> listExpr,
表达式< Func< U,V>> memberExpr)
{
var meta = ModelMetadata.FromLambdaExpression(listExpr,helper.ViewData);
var listName = meta.PropertyName;

string itemName = GetFullPropertyName(memberExpr);

return string .Format( value:{1},attr:{{id:'{0} _'+ $ index()+'__ {1}',name:' {0} ['+ $ index()+']。{1}'}},listName,itemName);
}







itemName是有价值Mobjlineitem.productid



当它刚刚产生没有错误时



任何解决方案?

iam getting error Mobjlineitem not defined

<tbody data-bind="foreach: MobjLineitems">
                       <tr>
                           <td>
                               <input data-bind="@Html.DataBinding(m => m.MobjLineitems, it => it.MobjLineitem.productid)" type="text" value="" />
                           </td>
                           <td class="number">
                               <input data-bind="@Html.DataBinding(m => m.MobjLineitems, it => it.MobjLineitem.rate)" type="text" value="" class="number pure-input-2-3" />
                           </td>
                           <td class="number">
                               <input data-bind="@Html.DataBinding(m => m.MobjLineitems, it => it.MobjLineitem.quantity)" type="text" value="" class="number pure-input-2-3" />
                           </td>
                           <td class="number">
                               <input data-bind="value: Value" readonly="readonly" type="text" value="" class="number pure-input-2-3" />
                           </td>
                           <td>

                               <input type="button" class="pure-button" data-bind="click: $parent.delItem" value="delete"/>

                           </td>
                       </tr>
                   </tbody>



Iam using helper as below

public static string DataBinding<TModel, U, V>(this HtmlHelper<TModel> helper, Expression<Func<TModel, IEnumerable>> listExpr,
          Expression<Func<U, V>> memberExpr)
        {
            var meta = ModelMetadata.FromLambdaExpression(listExpr, helper.ViewData);
            var listName = meta.PropertyName;

            string itemName = GetFullPropertyName(memberExpr);

            return string.Format("value: {1}, attr: {{ id : '{0}_' + $index() + '__{1}', name: '{0}[' + $index() + '].{1}' }}",listName, itemName);
        }




itemName is having value Mobjlineitem.productid

when its just productid there is no error

Any solution?
