Orchard CMS:基于层的条件 CSS 类 [英] Orchard CMS: Conditional CSS Class based on Layer

问题描述

如果我在特定层中，我正在尝试添加一个 css 类.

I am trying to add a css class if I am in a particular layer.

所以 2 个问题:

1. 是否可以在 Razor 视图中识别当前层.类似的东西:

1. Is it possible to identify the current layer in a Razor view. Something like:

if(currentLayer == "TheHomepage") { ... }

if(currentLayer == "TheHomepage") { ... }

在图层上处理 HTML 条件是正确的方法，还是在 Orchard 中有更好的方法来做到这一点?

Is the the right way to approach HTML conditional on layer, or is there a better way to do this in Orchard?

推荐答案

如果您需要查看当前处于活动状态的图层，您可以执行以下操作:

If you need to see which layers are currently active, you can do something like this:

@using Orchard.Widgets.Services
@{
    var widgetsService = WorkContext.Resolve<IWidgetsService>();
    var ruleManager = WorkContext.Resolve<IRuleManager>();

    var activeLayerNames = new List<string>();
    foreach (var layer in widgetsService.GetLayers()) {
        try {
            if (ruleManager.Matches(layer.LayerRule)) {
                activeLayers.Add(layer.Name);
            }
        } catch(Exception ex) {
            // Problem occurred during layer rule evaluation.
            // Just treat it as though the layer rule did not match.
        }
    }

    if (activeLayerNames.Contains("TheHomePage")) {
        /* ... Your code here ... */
    }
}

上面的大部分代码在驱动程序或控制器中更有意义，但如果您只在视图层工作，则可以这样做.

Much of the code above makes more sense in a driver or controller, but if you are working only in the view layer, you can do it this way.
