asp.net mvc 3 - MVC3 DropDownList + JSON + selected issue -


i have strange behaviour between website (mvc3 + jquery) , mobile version (mvc3 + jquery mobile) split in 2 distinct solutions.

i using following code change concent of dropdown (searchvalue) according 1 (searchby).

razor:

@html.dropdownlistfor(x => x.selectedsearch, new selectlist(model.searchby, "key", "value"), new { onchange = "getvalues($(this).val());" }) @html.dropdownlistfor(m => m.selectedsearchvalue, new selectlist(model.searchvalue, "key", "value"))

json:

$.ajax({ type: "post", url: '@url.action("getvalues", "search")', data: "{searchid:" + searchid + "}", contenttype: "application/json; charset=utf-8", datatype: "json", success: function (data) { var options = $('#selectedsearchvalue'); $('option', options).remove(); // remove previous $.each(data, function () { options.append($('<option/>').val(this.id).text(this.display)); }); } });

this code working fine on website (jquery) not case on mobile website (jquery mobile) working opera mobile not ff or ie or safari ... (i tried user agent simulate mobile devices)

the values of searchvalue dropdown correctly set @ end of json call, selected value previous selected value (which not in possible values of dropdown). not sure clear give little example :

i have following possibilities searchby: - name - car

when select name, display in searchvalue "name1", "name2", etc etc , when select car, display in searchvalue "car1", "car2", etc etc

but previous code on mobile website, when change value "name" car", dropdownlist correctly refilled right values ("car1", "car2", etc) selected value previous 1 (e.g. "name1") if not in possible values of dropdown. try select manually first value nothing happens :

$('option[value=' + mybeautifulvalue + ']').attr('selected', 'selected');

do have idea fix problem? doing wrong?

thank in advance help, nico

ps: sorry poor english

ok, found solution. have refresh dropdown, wierd! : 

var myselect = $("#selectedsearchvalue"); myselect[0].selectedindex = 0; myselect.selectmenu('refresh');

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
