regex - Regular Expressions:JavaScript -

What exactly would be the following statement:

a.replace (/ [^ \ w- ] / G, '-');

I have to find all the examples of '-' in between words and replace it with '-'.

In addition to this, if I get any examples

"Hi @ Raju, how do you do it?"

P> I want to secret the whole word like the word given below:

"Hi-Raju-what-what-what to do"

Terms:

  1. Change the white space with '-' 2. Replace special characters with '-'. 3. If we have more than one '-' result, replace the single with '-'.
  2. Remove '-' at the beginning and end of the string.

    The following is a possible solution: 

      "Hi how do you do raju?". (+/- +/g, '-') .replace (/ ^ [\ s -] + | [\ s- (= \ s + | [@ \?] / G, '-').] + $ / G, '')) & Gt; Output: "hi-raju-u-to-do-do"   
     You can add any other 'special' character to the first code in  [] .

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...
