javascript - Add two extra options to a select list with ngOptions on it -

-

i have bunch of select lists , i'm trying add "none" , title option them. code looks so:

<select ng-options="value.name value in values" ng-model="selection">     <option value="" disabled>{{title}}</option>     <option value="">none</option> </select>

for right now, cannot add them data trying find way working. when load them first time, "none" option not there. title there , works intended, seems cannot add 2 blank entries select list.

the easiest way have "none" option added data it's not possibility me. there proper way achieve want?

that's correct, can have 1 hard-coded element. <option ng-repeat> can technically done, method cleanly supports binding strings, kludgey bind objects, you're doing.

you can't add "none" data, can next best thing: prepend array ng-options iterating across, using filter:

app.filter('addnone', function () {     return function(input) {         var newarray = input.slice(0); //clone array, or you'll end new "none" option added "values" array on every digest cycle.         newarray.unshift({ name: "none" });         return newarray;     }; })

then use filter this:

 <select class="form-control" ng-options="value.name value.name value in filter.values | addnone" ng-model="filter.selected" ng-change="gosearch()">                     <option value="" disabled>{{filter.name}}</option>                 </select>
