angular.js - 关于scope中数据赋值后自动绑定的问题

Question

我需要复制出scope中的数据，如$scope.a给$scope.b，发现改变$scope.b时候$scope.a也会自动改变，但是我不希望他们两个之间会自动数据绑定。我用var c = $scope.a;$scope.b = c;它们之间也会自动数据绑定，应该如何做才能让它们之间不会自动绑定呢？

Answer 1

Use angular.copy

Answer 2

C If it is an object, a and b actually point to the same object. Using angular.copy to make a copy can solve the problem, but you may need to review whether this design is reasonable. Data-driven development should ensure that the data is consistent and unique. .

cIf it is a basic type, such as strings and numbers, the situation you mentioned should not happen
