javascript - How to Remove Previously Drawn InfoVis Space Tree -

-

I am using InfoVis to create a space tree view in one of my projects. Since this is an interactive web site, space trees need to be re-established every time and the user has changed the preferences.
This requires the space tree to be completely cleaned and to pull a new tree again in one place. In addition, the charting area can be resized as the page size is different. For this, it is necessary to attract the Space Tree again.

Before drawing a new picture, I came across several issues while trying to clear the pre-prepared space tree. I am using the following code segment to clear the previous drawing, but it is failing badly. 

  st.clearNodesInPath (); St.labels.clearLabels (true); St.canvas.clear ();   
 If someone can guide me how to solve it it would be good because it is blocking my progress Thanks in advance.

 This was resolved in the following way. 
  
 Even after clearing element data structures within the HTML div element of the InfoVis chart, there was a problem due to the path of the devil elements generated. Those who were previously shown clearly in the images attached. 
  
 It was resolved as follows. 
  
  var list = document.getElementById ("idOfParentElement"); List.removeChild (list.childNodes [0]);   
 Code Piece Parent Removes InfoVis element and it clears all the generated child elements. This will eventually clear the canvas object, where visualization will be prepared. 
  
 It solved my problem, hoping that it helps for the same problem.

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
