I have been most part of the morning working on a solution for when I need to assign several values to an entity on my form.
So, the idea is I have an Entity called QualityData and this entity can have different MechanismIdentifiers.
Best solution I thought of, use a multiple select.
All works fine combining both these solutions:
AngularJS selecting multiple options
Get value when selected ng-option changes
I can access the array of selected options, assign it to my entity, etc... But I have a "minor" fallback, which is that I can't get the preselected options (the ones that would come from the server when loading data for editing) to be highlighted in the select field when using a dynamic approach such as <option ng-repeat> or ng-options, it will only work when hardcoding the options. Another bug is that if I wish to add more values than those that are in the preselected array, it will erase all values present in it when using a dynamic approach, working fine when harcoding.
The markup:
<select multiple ng-change="showAlert(selectedValues)" ng-model="selectedValues">
<!--ng-options="resDatasIdOfMechanism as resDatasIdOfMechanism.name for resDatasIdOfMechanism in resDatasIdOfMechanisms track by resDatasIdOfMechanism.id" value="resDatasIdOfMechanism.id">-->
<option value="1">{{resDatasIdOfMechanisms[0].name}}</option>
<option value="2">{{resDatasIdOfMechanisms[1].name}}</option>
<option value="3">{{resDatasIdOfMechanisms[2].name}}</option>
</select>
If I try to use the line that is commented, it's when the marked option will not work
The controller:
$scope.selectedAlready = [{id:1, name:"Based on Antibiogram"}];
$scope.selectedMechanisms=[];
$scope.resDatasIdOfMechanisms = [{id:1,name:"Based on Antibiogram"}, {id:2,name:"Molecular"}, {id:3,name:"Genetic"}];
$scope.selected = $scope.selectedAlready;
$scope.selectedValues = [];
$scope.$watch('selected', function(nowSelected){
$scope.selectedValues = [];
if( ! nowSelected ){
return;
}
angular.forEach(nowSelected, function(val){
$scope.selectedValues.push( val.id.toString());
console.log("look");
});
});
$scope.showAlert=function(listOfMultipleChoices){
//alert(object);
}
EDIT to add jsfiddle link which is working but I still haven't found solution to original question: https://jsfiddle.net/StevenEvenSteven/ybapx09w/
