javascript - declare multiple variables into a variable angularjs -

-

how put multiple variables 1 variable can minify code usage. how declare can use $scope.bundle instead of these 3 variables : $scope.acc.city, $scope.acc.state , $scope.acc.country. global variable carry multiple variables can use everywhere without need write variables again , again.

the way want : 

$scope.bundle = [{$scope.acc.city, $scope.acc.state, $scope.acc.country}];   $scope.postcode = resp.content; if ($scope.postcode.length > 0) {    $scope.bundle = $scope.postcode[0];    $scope.acc = $scope.bundle; } else {    $scope.bundle = '';    $scope.acc = $scope.bundle; }

instead of : 

if ($scope.postcode.length > 0) {    var data = $scope.postcode[0];    $scope.acc.city = data.city;    $scope.acc.state = data.state;    $scope.acc.country = data.country; } else {    $scope.acc.city = '';    $scope.acc.state = '';    $scope.acc.country = ''; }

you're creating array of objects, need provide keys values

$scope.bundle = [    {        city    : $scope.acc.city,         state   : $scope.acc.state,         country : $scope.acc.country    } ];

then can access like

$scope.bundle[0].city

if you've got 1 item (instead of array) can create object directly

$scope.bundle = {     city    : $scope.acc.city,      state   : $scope.acc.state,      country : $scope.acc.country };

then can access without index property

 $scope.bundle.city

PHP DOM loadHTML() method unusual warning -

-
i had following code works fine on localhost: $document = new domdocument(); $document->loadhtml($p_result); $form = $document->getelementsbytagname('form')->item(0); // code continues using $form variable after same code updated on outside server, loadhtml() failed , issued warning. warning: domdocument::loadhtml() expects parameter 1 valid path, string given in path/name/to/script.php returned null instead of object code pretty gets fatal error. note contents of $p_result absolutely same on outside server , on localhost. but why displays kind of warning , why not work? doesn't loadhtml() expects argument 1 string in first place? why method expects parameter 1 valid path ? just make clear i'm not calling loadhtmlfile() , i'm calling loadhtml() . thanks. you're affected one of php bugs . issue present in php 5.6.8 , 5.6.9. have affected php version on server, , bug-free version on localhost. the bug forbids null

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
