javascript - Turn all function arguments values into one flatten array, to avoid array inside another array -


i'm working in function , need turn function's arguments in 1 array, even if 1 argument array (or list of values). i need array_merge() in php, keys not needed, values wanted.

edit 1:
i'm not looking how turn object arguments array. need values passed argument single array. if 1 or more arguments array or object, values need merged 1 array. example provided.

for example:
foo('bar', function, [1,2,3], [nodelist], window);
array => ['bar', function, 1, 2, 3, < htmlelement>, < htmlelement>, window]

pay attention on [nodelist], must turn htmlelements.

done far:
i've done function below, wanna know if better way. comments/hints appreciated. 

function toarray(obj) {   var k = object.keys(obj);   var = 0, l = k.length;   if (isstring(obj) || l == 0 || obj === window) {     return obj;   } else {     var objs = [];     while (i < l) {       objs = objs.concat(toarray(obj[k[i]]));       i++;     }     return objs   } } function isstring(obj){   return (typeof obj === 'string' || obj instanceof string); }

edit 1:
usage: 

var arg1 = 'bar',     arg2 = [1,2,3],     arg3 = document.queryselectorall('body');  foo(arg1, arg2, arg3) {    var myarray = toarray(arguments);    //myarray: ['bar', 1, 2, 3, <body>] }

use keyword arguments

function findmax() {    var i;    var max = -infinity;    (i = 0; < arguments.length; i++) {      if (arguments[i] > max) {        max = arguments[i];      }    }    return max;  }  document.getelementbyid("demo").innerhtml = findmax(4, 5, 6);

edit

this how flatten array.

var arg1 = document.queryselectorall('p');  var arg2 = 3;  var arg3 = [1, 2, [3, 2, 3, [45, arg1]]];  var arg4 = function() {};  var arg5 = {    a: {      b: 3,      c: 2    }  };  var arg6 = window;    function flatten() {      /*gets arguments past in*/      var arrays = arguments;      var last = 0;      /*flattens array*/      while (arrays.length != last) {        last = arrays.length;        arrays = [].concat.apply([], arrays);      }      /*maps nodelist array*/      arrays = arrays.map(function(obj) {        var arg1 = [];        if (isnodelist(obj)) {          [].foreach.call(obj, function(node) {            arg1.push(node);          });          return arg1;        } else {          return obj;        }      });      /*flattens node list arrays*/      last = 0;      while (arrays.length != last) {        last = arrays.length;        arrays = [].concat.apply([], arrays);      }      /*returns unique array*/      return unique(arrays);    }    /*makes array unique*/    function unique(a) {    return a.reduce(function(p, c) {      if (p.indexof(c) < 0) p.push(c);      return p;    }, []);  }    function isnodelist(obj) {    var objtype = {}.tostring.call(obj);    return (objtype === '[object nodelist]' ||      objtype === '[object htmlcollection]' ||      objtype === '[object object]' && /^\s?function/.test(obj.item)) && obj.length; // returns length of nodelist if true        };    document.getelementbyid('r').innerhtml = flatten(arg1, arg2, arg3, arg4, arg5, arg6);

java - pagination of xlsx file to XSSFworkbook using apache POI -

right in code, reading xlsx file, xssfworkbook, , writing database. but, when size of xlsx file increases, causes outofmemory error. can not increase server size, or divide xlsx file pieces. tried loading workbook using file (instead of inputstream), didn't either. i looking way read 10k rows @ time (instead of entire file @ once) , iteratively write workbook , database. is there way apache poi? poi contains called "eventmodel" designed purpose. it's mentioned in faq : the ss eventmodel package api reading excel files without loading whole spreadsheet memory. require more knowledge on part of user, reduces memory consumption more tenfold. based on awt event model in combination sax. if need read-only access, best way it. however, may want double check first if issue somewhere else. check out this item : i think poi using memory! can do? 1 comes quite lot, reason isn't might think. so, first thing check - what's source of prob...

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). ...
