Utilizing ngModel bindings in AngularJS to link controller data, or invoking functions through ngModel

I am attempting to link an unspecified array index based on a certain property in angularjs.

    <select id="iditemtype" ng-model="bindSpecificAttribute(entity, e)"
        ng-options="e as e.configValue for e in allConfig() | filter:{typeName:'ItemType'}">
    </select>

//javascript method inside controller

    function bindSpecificAttribute()
    {
        var dataIndex = -1;
        for(var i=0;i<entity.attributes.length;i++){
            if(entity.attributes[i].type=='ItemType'){
                dataIndex = i;
                break;
            }
        }

        if(dataIndex==-1){
            entity.attributes.push(0, e);
        }
        else
            entity.attributes[dataIndex] = e;
    }

The excerpt above reflects my desired outcome. I aim to connect a specific attribute from a dropdown list.

Answer №1

In this scenario, it is not possible to pass a function to ng-model because Angular needs the ability to update the value when the user modifies the input field. Instead, you can utilize $watch or the ng-change directive in conjunction with the select element. By calling a function on the select value change and assigning the corresponding variable within the controller function linked to ng-change, you can achieve your desired outcome.
