从两种方式的数据绑定到一种方式的数据绑定angularjs

Question

I have this directive

<directive dataset="dataObject"></directive>

my directive link function have something like this:

var oldData = '';

var initFunction = function(){
  oldData = scope.dataObject;
}

scope.reset = function(){
  scope.dataObject = oldData;
};

The problem is that when i modify the data in some way, when i want to reset the dataobject to its default value before modifying but everytime i do this, the two way databinding its messing my data, now the problem is that this is for a plot so the data is modified all the time

Answer 1

Use angular.copy to create "other reference"

var initFunction = function(){
  oldData = angular.copy(scope.dataObject);
}
