Escaping single quote from an MVC 3 Razor View variable

问题

I have a variable within item.Name that contains the string "It's Tuesday!". To alleviate javascript errors, in the c# controller I have already escaped this single quote. On the webpage, it appears like this "It\'s Tuesday!".

This at least prevents any javascript errors, however, I do not want the actual string displayed to contain the backslash that has escaped it.

How might I be able to revert the escaping once the javascript errors have already been taken care of? This feels like a rather simple problem, but I am a bit unfamiliar with MVC 3. Any hint is much appreciated! My searching did not find me any example specific to this.

An example of my code in the Razor View:

@foreach (var item in Model)
{ 
    @Html.DisplayFor(modelItem => item.Name) // item.Name = "It\'s Tuesday!"
}

Create an extension method you can use or simply encode directly. I would not encode prior to the view getting it unless you have a separate property in your viewmodel meant for this (not a bad idea()

This is not tested but something along these lines


public static class HtmlExtensions

{
    public static IHtmlString JavaScriptEncode(this HtmlHelper html, string item)
    {
        return new HtmlString(HttpUtility.JavaScriptStringEncode(item));
    }
}

You can then just call @Html.JavaScriptEncode(yourProperty) from the view or simply reference your encoded property name.

The following can be used to prevent encoding of the output again. This does however rely on you properly dealing with it yourself.

MVCHTMLString

@MvcHtmlString.Create(yourString)

I prefer to make my views dumb. Therefore, I'd have a property called something like 'Display' or 'DisplayName' which handled the escaping for the view.
