MVC3 TextBoxFor with encoded text

问题

Is there a way to use TextBoxFor helper with encoded text?

for example: When using the following helper of MVC3 With Razor view engine :

@Html.TextBoxFor(model => model.Description)

and the value of model.Description is encoded, for example:

 <script>alert();'</script>

the result is text box with the the encoded string, when the wanted result is text box with the decoded string:

 <script>alert();'</script>

Is there a way to use the MVC TextBoxFor with encoded string instead of using

@Html.TextBox("Description", Server.HtmlDecode(Model.Description))

?

回答1:

You have to html-decode your string.

Use the System.Web.HttpUtility.HtmlDecode for that.

System.Web.HttpUtility.HtmlDecode("<script>alert();'</script>")

will result in

<script>alert();'</script>

TextBoxFor does not support that so, you have 2 options

1. Decode before display

    @{
        Model.Description = System.Web.HttpUtility.HtmlDecode(Model.Description);
     }
    @Html.TextBoxFor(model => model.Description)

2. Use @Html.TextBox for this

    @Html.TextBox("Description", System.Web.HttpUtility.HtmlDecode(Model.Description))

hope this helps
