控制器:
public ActionResult Filter()
{
ViewBag.Accounts = BusinessLayer.AccountManager.Instance.getUserAccounts(HttpContext.User.Identity.Name);
return View();
}
视图:
<td>Account: </td>
<td>@Html.DropDownListFor("accountid", new SelectList(ViewBag.Accounts, "AccountID", "AccountName"))</td>
ViewBag.Accounts包含Account具有的对象AccountID,AccountName以及其他属性.我想要一个DropDownList被调用的accountid(以便在Form Post上我可以传递所选的AccountID)并DropDownList显示AccountName具有AccountIDas值的while .
我在视图代码中做错了什么？
我有bootstrap的以下菜单
HTML
<div class="navbar-collapse collapse">
<ul class="nav navbar-nav">
<li class="active" id="homeL"><a data-scroll href="#Home">Home</a></li>
<li><a href="#">About</a></li>
<li class="" id="workL"><a data-scroll href="#Work">Work</a></li>
<li><a href="#">Contact</a></li>
</ul>
</div>
<li>当点击家庭或工作时,如何将课程更改为激活？
以下内容对我不起作用
$("#homeL").on("click",function(){
$(".nav navbar-nav li").removeClass("active");
$(this).addClass("active");
});
如何在Migradoc中添加一个简单的水平线,以便将该行上方的内容与该行下方的内容分开？
