  $ ('# pnlChangeLoginInfo & gt; div & gt; div & gt; input. Format-control'). RemoveClass ('form-control');   
 Please note that  very accurate  match  input.form-control  element  exactly  3  Level below the #pnlChangeLoginInfo  element However, I do not see any other element matching at other levels that match the  input.form-control  criteria, so you get the following The work is fine:  
  $ ('# pnlChangeLoginInfo input.form-control'). RemoveClass ('form-control');   
 The advantage of the other is that it will be more flexible for future small DOM updates.

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
