javascript - Using Wildcards to Search Arrays in JS -

-

I am thinking that it is possible to create an array of elements and then create an event listener using a wildcard that Will trigger when interacting with any of these elements. A sample of how this may look like: 

  var e = new array (); E [1] = document.getElementById ('some elements'); E [2] = document.getElementById ('some other elements'); E.onmouseup = function {if (e == e [1]) {// some code here} and if (e == e [2]) {// some code here}}    
 
 
 Actually there is no  wildcard , but something that only allows you to have an event handler All elements will allow binding - Event delegation:  
  document.body.addEventListener ('mouseup', function (event) {var target = event.target; if (target == E [ 1]) Some code warnings here ('some element');} and if (target == E [2]) {// some code warnings here ('some un Other elements');}}, false); Due to this fact it works because the DOM transports the tree to the bubble until the code reaches  , and requires it from there. The action is transmitted.  
 There is a demo with this approach:

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
