如何在Javascript Push中的索引内传递变量

Question

How to pass variable inside index in JavaScript push.I am using angular. This is what I did so far:

angular.forEach(Val, function (Value,Key) {
    angular.forEach(Value, function (Value1,Key1) {
        saveDetailArr.push({ 'option_id':Val['option_id'],Key1:$scope[Key1] });
    });
});

Key1 contains "header,footer,text1,text2,left_contianer etc". Basically,I want the value of Key1 instead of string "Key1" Currently,it look like: {'option_id':21,Key1:'abc'} But I want it like this: {'option_id':21,header:'abc'} How can I achieve this:

Use bracket notation for variable property names. In your case obj[Key1] should work:

angular.forEach(Val, function (Value,Key) {
    angular.forEach(Value, function (Value1,Key1) {
        var obj = { 'option_id':Val['option_id'] };
        obj[Key1] = $scope[Key1];
        saveDetailArr.push(obj);
    });
});
