在MVC视图VS VS的HtmlHelper动作条件逻辑 [英] conditional logic in mvc view vs htmlhelper vs action

问题描述

我有一个需要一些条件逻辑来决定视图的中间渲染的几大块HTML的大图。我有我的模型，它可以有它决定了HTML要输出几个不同值的属性。

I have a large view that needs some conditional logic to decide which of several html chunks to render in the middle of the view. I have a property on my model which can have several different values which determines the html to be output.

我通常把条件逻辑在一个HTML帮手，但考虑到每个输出是HTML的一个公平块，我不知道，在C＃文件逃脱这些将是巨大的。我也可以把逻辑的行动，并呈现不同的意见，但鉴于多数的观点是一样的，这似乎并不算很好。所以我离开了我多，如果在我看来报表（或部分？），这似乎也难看（而且显然是无法验证的）。

I would normally put conditional logic in an html helper, but given that each output is a fair chunk of html, I am not sure that escaping these in a c# file would be great. I could also put the logic in the action and render different views but given that the majority of the view is the same, this does not seem great either. So I am left with multiple if statements in my view (or partial?) which also seems ugly (and is obviously untestable).

什么是这样做的最佳方式？

What is the best way of doing this?

（我的情况下，使用MVC3有新的东西和时髦的我可以使用！）

推荐答案

我通常把单独的视觉块在自己的谐音。然后，我的观点有条件地调用每个部分与Html.Partial。这样可以使您主视图从腹胀。

I usually put separate visual chunks in their own partials. Then my view conditionally calls each partial with Html.Partial. This keeps you main view from bloating.

在一般情况下，我尽量避免含有比单个元素更Html.Helpers。

In general, I try to avoid Html.Helpers that contain more than a single element.

是这样的：

@if(Model.HasA) 
{
    @Html.Partial("widgetdetails-hasa")
}

@if(Model.HasB)
{ 
    @Html.Partial("widgetdetails-hasb")
}
// etc
