javascript - Call function on dynamically created DOM -


i have function countdown:

 function gettimeremaining(endtime){             var t = date.parse(endtime) - date.parse(new date());             var seconds = math.floor( (t/1000) % 60 );             var minutes = math.floor( (t/1000/60) % 60 );             var hours = math.floor( (t/(1000*60*60)) % 24 );             var days = math.floor( t/(1000*60*60*24) );             return {                 'total': t,                 'days': days,                 'hours': hours,                 'minutes': minutes,                 'seconds': seconds             };         }          function initializeclock(id, endtime){             var clock = document.getelementbyid(id);             var daysspan = clock.queryselector('.days');             var hoursspan = clock.queryselector('.hours');             var minutesspan = clock.queryselector('.minutes');             var secondsspan = clock.queryselector('.seconds');              function updateclock(){                 var t = gettimeremaining(endtime);                  daysspan.innerhtml = t.days;                 hoursspan.innerhtml = ('0' + t.hours).slice(-2);                 minutesspan.innerhtml = ('0' + t.minutes).slice(-2);                 secondsspan.innerhtml = ('0' + t.seconds).slice(-2);                  if(t.total<=0){                     clearinterval(timeinterval);                 }             }              updateclock();             var timeinterval = setinterval(updateclock,1000);         };

now want call function when click on button , open popover window in window want run counddown function write below:

function startpop(){     $('.btn').popover({     template: '<div id="mypopover1" class="popover popover-default">'     +'<div class="arrow"></div>'     +'<div class="popover-title"><span class="close" data-dismiss="popover-x">&times;</span>title</div>'     +'<div class="col-md-12">'     +'<div id="clockdiv" class="text-center">'            +' <div><span class="days"></span><div class="smalltext">days</div></div>'            +' <div><span class="hours"></span><div class="smalltext">hours</div></div>'            +' <div><span class="minutes"></span><div class="smalltext">minutes</div></div>'            +' <div><span class="seconds"></span> <div class="smalltext">seconds</div></div>'         +'</div>'        +'<div class="popover-footer">'  +'<div class="input-group" style="padding:10px;">'         +' <input id="demo1" type="text" class="form-control spin" name="demo1" value="{{$article->price}}">'         +'<div class="input-group-btn">'         +'<button type="button" class="btn btn-danger">post bid</button></div></div>'             +'</div>',  });  };   function popforbid(){     $('.popover').hide();     $('.btn').click(function() {     $('.btn').not(this).popover('hide');     spinner();     var j = $(this).attr('price');     var s = $(this).attr('start');     $('.spin').val(j);     s = new date(s);     initializeclock('clockdiv', s); }); };

but cant view initializeclock('clockdiv', s);

how make possible?

you can delegate events

$('body').on('click', '.btn', function(){     // });

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
