javascript - Newly added dom elements not being selected -


i have image list has ability load more content via ajax. on default there images loaded list. when user scrolls 4 items added list. list refreshed via ajax every 15 seconds , replaces top 7 items in list. problem when 4 new items added list selector seems ignore items, doesn't select 0 index.

i know sounds confusing i'll try , demo simple example.

ex

$(function () { // update channelstats settimeout(function () { var refresh = setinterval(updatechannels, 15000); updatechannels(); }, 15000); function updatechannels() { $.ajax({ type: "post", url: "ajax/imagelist.aspx/updateimages", data: "{}", contenttype: "application/json; charset=utf-8", datatype: "json", success: function (data) { // newest var $newestresults = $('#newest .pcvideomaincontainer:lt(7)'); $newestresults.fadeout('slow'), function () { remove() }; $.each($newestresults, function (index, value) { $(this).delay(index * 250).animate({ opacity: 0 }, 250, function () { $(this).remove(); $('#pccontentholder_newest').append(data.d.newest.htmlchannelsegments[index]); }); }); }); } });

[note order of numbers - order images loaded]

on initial page load first images loaded

　1. on initial page load following images loaded

1 2 3 4 5 6 7

　2. when user scrolls remaining images shown

1 2 3 4 5 6 7 8 9 10 11

　3. update script runs 1st time

8 9 10 11 1 2 3 4 5 6 7

　4. update script runs 2nd time

4 5 6 7 1 2 3 4 5 6 7

　5. each , every subsequent time update script runs order is

4 5 6 7 1 2 3 4 5 6 7

from can tell 4 newly added elements not included in $('#newest .pcvideomaincontainer:lt(7)') selection. i'm not sure how use "live" in scenario, or if there other technique.

i'm not sure if main problem or not, part of code missing $(this). before remove() , missing closing paren. have this:

 var $newestresults = $('#newest .pcvideomaincontainer:lt(7)'); $newestresults.fadeout('slow'), function () { remove() };

it should this:

 var $newestresults = $('#newest .pcvideomaincontainer:lt(7)'); $newestresults.fadeout('slow'), function () { $(this).remove() });

once fix this, $newestresults dom objects removed i'm unsure why try operate on them again following lines of code.

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
