javascript - Show/Hide Content without reloading the page -

-

I have three content boxes that I want to show and hide using controls. The HTML is as follows: 

  & lt; Div id = "leermat1" & gt; The content here & lt; One square = "page-next" & gt; Next & lt; / A & gt; & Lt; One square = "back-past" & gt; Previous & lt; / A & gt; & Lt; / Div & gt; & Lt; Div id = "leermat2" & gt; The content here & lt; One square = "page-next" & gt; Next & lt; / A & gt; & Lt; One square = "back-past" & gt; Previous & lt; / A & gt; & Lt; / Div & gt; & Lt; Div id = "leermat3" & gt; The content here & lt; One square = "page-next" & gt; Next & lt; / A & gt; & Lt; One square = "back-past" & gt; Previous & lt; / A & gt; & Lt; / Div & gt;   
 I have two anchors pug-next and page-back, which should be visible to the content divide at any point:  
 I want to write like jquery , When # leermat1 'pag-next' is clicked, it hides #lermet1 and shows #lermat2 then when #lermat 1 is hidden and shows #lermat2, when on '.pag-next' Is clicked, it hides #Lermat 2, and #Lermat 3 shows  
 Apart from this, 'Pag-east' is also similarly should work.  
 I started with the following, but I do not know where to go from here.  
  $ (document) .ready (function () {$ ('.pag-next'). ('Click', function () {$ ('# leermat1'). AddClass ('hide'); $ ('# lermat2'). AddClass ('show');});});   
 One more thing is that '.pag-next' should stop working after showing #lermat3.

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
