asp.net mvc - get the generated clientid for a form field

Question

Is there a way to get the client id generated for a field generated with a html helper?

i have several components that sometimes are inside another forms, and i wan't to attach javascript events to them.

so, for sample, i would like to have:

@Html.TextBoxFor(model => model.client.email)

<script> 
$('#@getmyusercontrolid(model=>model.client.email)').val("put your mail here");
</script>

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)
