javascript - Calling a function inside an other function in Js -


i not understand doing wrong in can explain me ?

https://jsfiddle.net/4pvhslew/

the idea have simple function of resuming text. if text long put "..." , on click display full length. , add span @ end hide again.

so #infocountry <p>element on 200 characters.

if(document.getelementbyid("infocountry").innerhtml.length > 200){     function test(){         var fullinfo = document.getelementbyid("infocountry").innerhtml;         var semiinfo = fullinfo.substring(0,200) + '<span id="plusinfo">...</span>';         document.getelementbyid("infocountry").innerhtml = semiinfo;           var voirplus = document.getelementbyid("plusinfo");         voirplus.addeventlistener("click", function(){             document.getelementbyid("infocountry").innerhtml = fullinfo +'<span id="moinsinfo">&nbsp; cacher</span>'; //affiche tout et "cacher"             var voirmoins = document.getelementbyid("moinsinfo");              voirmoins.addeventlistener("click", test()); // here bug ?         })      }     test(); }

it work until try recall it. console stay empty. don't understand miss understanding there :/

something work. doesn't require <span> question suggests

function showexcerpt(elem) {    var text = elem.textcontent;    if (text.length <= 200) return;        var link = document.createelement('a');    link.href="#";    link.onclick = function(event) {      event.preventdefault();      elem.textcontent = text;    };    link.textcontent = '...';        elem.textcontent = text.substring(0,200);    elem.appendchild(link);  }    showexcerpt(document.getelementsbytagname('p')[0]);  showexcerpt(document.getelementsbytagname('p')[1]);

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). ...
