MVC控制器未受到攻击 [英] MVC Controller Not Getting Hit

问题描述

当我单击详细信息视图"选项卡或任何与此相关的选项卡时，我无法获得控制器动作方法的提示.但是，如果我在javascript部分中将return false;注释掉，则可以找到要点击的操作方法，但是我的选择"标签未得到维护.

I can't get my Controller action method to get hit when I click 'Detail View' tab, or any tab for that matter. However, I can get the action method to hit if I comment out return false; in the javascript section, but then my 'Selected' tab is not maintained.

<script type="text/javascript">
$(document).ready(function () {
    $('.test').click(function () {            
        $('.test').removeClass('selected');
        $(this).addClass('selected');
        return false;
    });
});    
</script>    

<div id="tabs" class="shadetabs">
    <ul>
        <li class="test selected">@Html.ActionLink("Overview", "Index", "Statistics")</li> 
        <li class="test">@Html.ActionLink("Detail View", "Detail", "Statistics")</li>  
        <li class="test">@Html.ActionLink("Trends", "Trends", "Statistics")</li>                
    </ul>
</div>

推荐答案

通过返回false，您正在取消默认的链接操作，该操作将向控制器操作发送请求.因此，如果执行此操作，则需要手动发送请求(AJAX?)，并使用该请求的结果来修改DOM.例如:

By returning false you are canceling the default link action which is to send a request to your controller action. So if you do this you will need to manually send a request (AJAX?) and use the results from this request to modify the DOM. For example:

$('.test').click(function () {            
    $('.test').removeClass('selected');
    $(this).addClass('selected');
    $.ajax({
        url: this.href,
        success: function(result) {
            // TODO: do something with the result here
        }
    });
    return false;
});

或者您可以在没有任何JavaScript的情况下执行此操作.

Or you could do this without any javascript.

例如，您可以编写一个自定义HTML帮助器将会生成此菜单:

So for example you could write a custom HTML helper that will generate this menu:

public static MvcHtmlString MenuLink(
    this HtmlHelper htmlHelper, 
    string linkText, 
    string actionName, 
    string controllerName
)
{
    var routeData = htmlHelper.ViewContext.RouteData;
    string currentAction = routeData.GetRequiredString("action");
    string currentController = routeData.GetRequiredString("controller");
    if (actionName == currentAction && controllerName == currentController)
    {
        return htmlHelper.ActionLink(
            linkText,
            actionName,
            controllerName,
            null,
            new {
                @class = "selected"
            }
        );
    }
    return htmlHelper.ActionLink(linkText, actionName, controllerName);
}

然后简单地:

<ul>
  <li>@Html.MenuLink("Overview", "Index", "Statistics")</li>
  <li>@Html.MenuLink("Detail View", "Detail", "Statistics")</li>
  <li>@Html.MenuLink("Trends", "Trends", "Statistics")</li>
</ul>
