所以我有這個文本框的網頁上:TextBoxFor擴展的HtmlHelper
<%= Html.TextBox("EffectiveDate", Model.EffectiveDate.HasValue ? Model.EffectiveDate.Value.ToString("dd-MMM-yyyy") : "", new { @class = "economicTextBox", propertyName = "EffectiveDate", onchange = "parseAndSetDt(this); ", dataType = "Date" })%>
它存儲並顯示使用日期選擇器的日期。基本上,根據用戶的權限,我希望這個文本框被禁用/啓用。這很好,我可以做到這一點,但是,我想讓文本框的值=當前日期,如果他們沒有權限更改值。我可以用這個HTML擴展禁用它瓦特/權限:
public static MvcHtmlString TextBoxWithPermission(this HtmlHelper htmlHelper,
string name,
object value,
string[] permissions,
object htmlAttributes)
{
foreach (string permission in permissions)
{
if (Chatham.Web.UI.Extranet.SessionManager.DisplayUser.IsInRole(permission))
{
// the user has the permission => render the textbox
return htmlHelper.TextBox(name, value, htmlAttributes);
}
}
// the user has no permission => render a readonly checkbox
var mergedHtmlAttributes = new RouteValueDictionary(htmlAttributes);
mergedHtmlAttributes["disabled"] = "disabled";
return htmlHelper.TextBox(name, value, mergedHtmlAttributes);
}
但我怎麼用當前日期填充它,如果它被禁用?
