jquery or javascript to sort attributes of a html object before regex -


as follow on previous question using jquery find .each on .attr() regex,

i sort attributes alphabetically before running them through .each(). final output add child divs in order of attributes.

<div id="myelement" extra1="a" stuff="z" extra9="c" more="y" extra5="b" /div>

when parse through code below, outputs values b,c,a, need sort elements first order extra1, extra5, extra9, more, stuff run through .each()+regex values come out a,b,c 

var el = $('#myelement'); var attributes = el[0].attributes; $.each(attributes,function(i,attr){ var name = attr.nodename; var val = attr.nodevalue; var regex = /^extra\d$/; if(name.match(regex)) { $(parentdiv).append("<div id="+val+" /div>"); } });​

thx in advance art

per this mdn doc, attributes collection map, not array not have defined order. if wanted sorted, first have put in array, sort , .each() on sorted array.

or, collect results in .each() array, sort results , append sorted results in desired order @ end. looking @ code, think less work this:

var el = $('#myelement'); var attributes = el[0].attributes; var output = []; $.each(attributes,function(i,attr){ var name = attr.nodename; var val = attr.nodevalue; var regex = /^extra\d$/; if(name.match(regex)) { output.push("<div id="+val+" /div>"); } });​ $(parentdiv).append(output.sort().join(""));

this simple sort works if attributes can sorted lexigraphic order , don't go beyond extra9. if goes beyond single digit number, you'll have convert digits numbers , use custom sort function generate right sort order this:

var el = $('#myelement'); var attributes = el[0].attributes; var output = []; var regex = /^extra(\d+)$/; $.each(attributes,function(i,attr){ var name = attr.nodename; var val = attr.nodevalue; var matches, item; if(matches = name.match(regex)) { item = {}; item.html = "<div id="+val+" /div>"; item.num = parseint(matches[1], 10); output.push(item); } });​ // sort array of objects custom sort function output.sort(function(a, b) { return(a.num - b.num); }); // append data in correct order items sorted (var = 0; < output.length; i++) { $(parentdiv).append(output[i].html); }

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
