问题描述

如果Model.BicycleSellerListingId不大于0，我想有条件地禁用此按钮或将其隐藏.不确定该怎么做.

I would like to conditionally disable this button, or hide it, if Model.BicycleSellerListingId is not greater than 0. Not sure how to do it.

<div style="position:absolute; left:300px; top:633px;">
    @using (Html.BeginForm("Delete", null, new { id = Model.BicycleSellerListingId }, FormMethod.Post))
    {
       <button type="submit">Delete Listing</button>
    }
</div>

推荐答案

<div style="position:absolute; left:300px; top:633px;">
@using (Html.BeginForm("Delete", null, new { id = Model.BicycleSellerListingId }, FormMethod.Post))
{
   if(Model.BicycleSellerListingId < 0){
       <button type="submit">Delete Listing</button>
   }
}
</div>

@if(Model.BicycleSellerListingId < 0){
    <div style="position:absolute; left:300px; top:633px;">
    @using (Html.BeginForm("Delete", null, new { id = Model.BicycleSellerListingId }, FormMethod.Post))
    {
       <button type="submit">Delete Listing</button>
    }
    </div>
}

<div style="position:absolute; left:300px; top:633px;">
@using (Html.BeginForm("Delete", null, new { id = Model.BicycleSellerListingId }, FormMethod.Post))
{
    <button type="submit"  @((Model.BicycleSellerListingId < 0) ? "disabled" : "")>Delete Listing</button>
