How to extract data from a span element using AngularJS

Combining input values to create a cohesive string:

<input ng-model="first">
<input ng-model="second">
<span ng-model="result">{{first}} and {{second}}</span>

Is there a way to retrieve the resulting string from JavaScript? I'm aiming for something like

var myResult = $scope.result

but it seems like I might be overlooking a step...

Answer №1

If you're looking for a better approach, you might want to try something along these lines:

Solution

<input ng-model="first">
<input ng-model="second">
<span>{{result}}</span>

Approach

$scope.$watchCollection("[first,second]", function(newVals){
  $scope.result = newVals[0] + " and " + newVals[1];
});

Now you can easily access the result with var myResult = $scope.result. Check out this live example. It's worth noting that ngModel typically works best with inputs. According to the documentation:

The ngModel directive binds an input, select, textarea (or custom form control) to a property on the scope using NgModelController, which is created and exposed by this directive.

Consider creating your own directive if needed, or exploring alternative strategies before proceeding further with your current approach.
