javascript - AngularJS : ng-model dynamic binding does not work -

-

for reason cannot below 2 way binded. i'm trying make dynamic way of filling ng-model in forms

html:

<thead ng-repeat="field in fields"> <tr>     <th>         <select ng-model="{{field.day}}"></select>      </th>     <th>         <select ng-model="{{field.month}}"></select>     </th>     <th>         <select ng-model="{{field.morning}}"></select>     </th>     <th>         <select ng-model="{{field.eveningopen}}"></select>     </th>     <th>         <select ng-model="{{field.eveningclosing}}"></select>     </th>     <th>         <input type="checkbox" ng-model="{{field.checkmorning}}" />     </th>     <th>         <input type="checkbox" ng-model="{{field.checkevening}}" />                                             </th> </tr> </thead> </table>  <!-- add field --> <button class="btn" ng-click="addnew()"c>add field</button>  <!-- delete last field --> <button ng-show="fields.length > 0" class="btn" ng-click="deletelast()"c>remove last field</button>

and here angular/javascript:

$scope.fields = [];  $scope.addnew = function() {     var newitemno = $scope.fields.length+1;     $scope.fields.push(                         {                             'day'            :'day'+newitemno,                             'month'          : 'month'+newitemno,                             'morning'        : 'morning'+newitemno,                             'eveningopen'    : 'eveningopen'+newitemno,                             'eveningclosing' : 'eveningclosing'+newitemno,                             'checkmorning'   : 'checkmorning'+newitemno,                             'checkevening'   : 'checkevening'+newitemno                         }                       );     console.log($scope.fields); };  $scope.deletelast = function() {     $scope.fields.pop(); }

am missing limitation because did way on stack successfull :/

your problem ng-model="{{ obj.prop }}", should ng-model="obj.prop". using {{}} make angular attempt bind on resolved property of object. also, since objects not unique suggest adding track by function iteration.

edit: also, mentioned below select requires ngoptions directive. check-boxes can use string values ngtruevalue , ngfalsevalue directives.

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
