How to get the HTML id generated by asp.net MVC EditorFor

Question

I use the HTML Helpers to render my fields:

<%=Html.EditorFor(m => m.User.Surname)%> 

and the output would be something like this:

<input class="text-box single-line" id="User_Surname"            name="User.Surname" type="text" value="" /> 

The helper uses the className + '.' è fieldName to build the id.
I need to pass the id to a jQuery function. Is there a way to have it without hardcoding it? Maybe an helper which can use the ASP.NET MVC2 conventions?

Answer 1

ASP.NET MVC 4 has Html.IdFor() built in that can return this:

@Html.IdFor(m => m.User.Surname) 

Answer 2

See this question: get the generated clientid for a form field, this is my answer:

I use this helper:

public static partial class HtmlExtensions {     public static MvcHtmlString ClientIdFor<TModel, TProperty>(         this HtmlHelper<TModel> htmlHelper,          Expression<Func<TModel, TProperty>> expression)     {         return MvcHtmlString.Create(               htmlHelper.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldId(                   ExpressionHelper.GetExpressionText(expression)));     } } 

Use it just as you would any other helper: @Html.ClientIdFor(model=>model.client.email)
