javascript - how to allow geolocation in web page -

-

I am trying to run this code for latitude and longitude. My IE browser shows this message that geographic location services are not supported, and chrome says 'even after this page has been blocked from tracking your location' even after I set the location setting in Chrome all sites Allow me to track. help please. 

  & lt; Html & gt; & Lt; Top & gt; & Lt; / Head & gt; & Lt; Body & gt; & Lt; Input type = "button" id = "btn search" value = "search" onclick = "doSomething ();" /> & Lt; Script & gt; Function doSomething () {if (navigator.clocation) {navigator.geolocation.getCurrentPosition (handle_geolocation_query); Function handle_jolocation_corea (status) {warning ('wave:' + position.coords.latitude + '' + 'loan:' + position.coords.latitude); }} And {warnings ("I'm sorry, but geolocation services are not supported by your browser."); }} & lt; / Script & gt; & Lt; / Body & gt; & Lt; / Html & gt;    
 
 
 Change the scope of the handle_geolocation_query () to the external, and it should work. After this change works on my IE and Firefox.

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

-
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...
