javascript - Google Dart Core Pages Clear Children -

-

Whenever a page changes, then I am trying to clear the elements of children on a page. However, with the current method of doing so, nothing changes on the page, the same qualities are there. Right now, I've dynamically generated inputs depending on which different data is based, depending on which tab is selected and displays the appropriate core page (). Each time there is a way to reset the original-page so that different inputs appear properly for each tab? Children Clear () can not be the best way Please tell me that you need more information. 

  @observable int Page ChangeCount = 1; Zero page changed (old value, new value) {var pages = document.query selector ('core-page'); PageChangeCount ++; If (page == 0) {if (change page% 2! = 0) {pages.children.clear (); } Display (true); } And if (page == 1) {if (page changer% 2 == 0) {pages.children.clear (); } Display (false); }}    
 
 
 I have actually found all the elements through:  
  pages.children.removeWhere (Element E) {if (e.nodeName! = "Elements are looking for you")) {Back true;} else {return false;}

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
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
