Jquery not working properly? -


i'm having trouble jquery.
@ end of page, before closing </body> tag, have included jquery cdn:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.0/jquery.min.js"></script>

then @ top, in <head>, included own little code:

<script>         $(document).ready(function() {             $('#liked').click(function() {                 $('#changed').addclass('likeclicked');             });         }); </script>

this affecting following:

<button id='changed' class="like">      <span class="glyphicon glyphicon-heart" id='liked' style="font-size:2.0em;"></span> </button>

however, code isn't working. (css below). i've tried changing jquery hover instead of click, different classes or elements instead of id's. don't know i'm doing wrong.. idea? thanks.

.like { -webkit-appearance: none; outline: none; border: 0; background: transparent; -webkit-transition-duration: 0.2s; -moz-transition-duration: 0.2s; transition-duration: 0.2s; -webkit-user-select: none; -moz-user-select: none; -ms-user-select: none; user-select: none; }  .likeclicked { color: #00bc0e; }

order of loading important. code dependent on jquery library library needs load before code.

if in browser console see error $ not defined. stop further script execution in page

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). ...
