如何检查呈现的局部视图？

Question

I would like to render common data within these div elements.

<div id=element1>
    @Htm.Partial("CommonView")
    @*Other data...*@
</div>
<div id=element2>
    @Htm.Partial("CommonView")
    @*Some other data...*@
</div>
<div id=element3>
    @Htm.Partial("CommonView")
    @*More other data...*@        
</div>

My common view looks something like this

<input id="txtSomethingElse" class="input"/>

I can't have elements with same ids on the same page, but I need to be able to get values from input element. How can I implent some Razor logic that will add a prefix or sufix to txtSomethingElse

I would like it to be rendered like this

<div id=element1>
    <input id="txtSomethingElse_1" class="input"/>
</div>
<div id=element2>
    <input id="txtSomethingElse_2" class="input"/>
</div>
<div id=element3>
    <input id="txtSomethingElse_3" class="input"/>
 </div>

Answer 1

you can easily use this over load of the Html.Partial method

PartialExtensions.Partial Method (HtmlHelper, String, Object)

http://msdn.microsoft.com/en-us/library/ee402926(v=vs.108).aspx

allowing you to pass a model to the partial view which in your case can be an int denoting an index

so you partial views changes to <input id="txtSomethingElse_@Model.ToString()" class="input"/> where Model is of type int

and your code where you are to render this view will change to

<div id=element1>
    @Htm.Partial("CommonView", 1)
    @*Other data...*@
</div>
<div id=element2>
    @Htm.Partial("CommonView", 2)
    @*Some other data...*@
</div>
<div id=element3>
    @Htm.Partial("CommonView", 3)
    @*More other data...*@        
</div>

Answer 2

you can do something like, say your model had an Id Property

<input id="txtSomethingElse@Model.Id" class="input" />

I'm not too good at razor, but I know the old school syntax would work

<input id="txtSomethingElse<%: Model.Id %>" class=input />

Answer 3

Couldn't you do:

@Html.InputFor(m => m.FirstThing, new { @id = @Model.FirstThing.Id + "txtSomethingElse" })
@Html.InputFor(m => m.SecondThing, new { @id = @Model.SecondThing.Id + "txtSomethingElse" })
...

More readable/easier than other answers.
