Define a variable in the controller
$scope.a_1 = "abc";
I want to output dynamically in the view, because this number is dynamic, so the output is definitely not possible {{'a_' + '1'}}, because the output is the string a_1, not the value of the variable a_1
To output the value of the variable a_1, you can use the $eval method:{{$eval('a_' + '1')}}
$eval is used as a scope method. If used in controller, it is used like this:$scope.$eval()
The above detailed explanation of the $eval method in angularjs is all the content I share with you. I hope you can give you a reference and I hope you can support me more.
