javascript - Execute change method on select hidden -

-

I have a list (menu) with value ?????? When a user clicks to execute the click function that hides the value of a selector it works fine, but does not display the information to display the correct option by selecting itself. 

  & lt; Ul & gt; & Lt; Li class = 'active-sub' & gt; & Lt; A href = '#' & gt; & Lt; Span & gt; SELECCIONE & lt; / Span & gt; & Lt; / A & gt; & Lt; Ul & gt; & Lt; Li class = 'is-sub' & gt; & Lt; An id = "S0001" href = '#' & gt; & Lt; Span & gt; Auto Nouveau & lt; / Span & gt; & Lt; / A & gt; & Lt; / li & gt; & Lt; Li class = 'is-sub' & gt; & Lt; An ID = "S0002" href = '#' & gt; & Lt; Span & gt; Product 2 & lt; / Span & gt; & Lt; / A & gt; & Lt; / li & gt; & Lt; / Ul & gt;   
  
  & lt; Script & gt; $ ("# S0001") click (function () {$ ("# proyecto"). Val ('S0001'); $ ("# proyecto"). Change.val ();}); & Lt; / Script & gt;   
 The selection of all these functionality is hidden  
   & Lt; Option value = '0001' & gt; Auto Nouveau & lt; / Options & gt; & Lt; Option value = 'S0002' & gt; CELEBRACIONES & lt; / Options & gt; & Lt; / Select & gt; & Lt; / Div & gt;   
 To work it correctly, once I change the value of the selection, the change event must be run and the correct information should be charged.   
 
 
 You need to call the  change  event:  
  $ ("# proyecto"). ()   
 Note: This will run the defined  change  handler, not native functionality

php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

-
I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177

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...
