Angular Array to String

Question

I was wondering how I could convert something like:

$scope.foo = [
               {name: "foo1", information : "bar1" },
               {name: "foo2", information : "bar2" }
             ]

into a JSON string? I searched Stack Overflow earlier for this question and was advised to use angular.toJson(obj, pretty) which I also researched on their website, but I wasn't able to successfully do it.

JSON.stringify($scope.foo) may be? If you want to convert it to String? — aymeba

angular.toJson($scope.foo, true) should work fine. What errors did you get? Also angular.toJson($scope.foo) would work since pretty is optional — charlietfl

What @charlietfl said. angular.toJson() has been in there for quite a while and the preferred method, as it strips any $$ prefixed properties, so the errors you're getting should expose where the issue lies. — Eric McCormick

I've written the following on chrome console:

var foo = [
      {name: "foo1", information : "bar1" },
      {name: "foo2", information : "bar2" }
]
JSON.stringify(foo);

the output was: "[{"name":"foo1","information":"bar1"},{"name":"foo2","information":"bar2"}]"

I believe that is what you want.

will include angular hashkeys if array was used in a repeater though, angular.toJson() strips them out

Stringify worked!!! Thank you guys for your help! I did try it earlier but I made a very basic error; I called Stringify before I declared the array in the javascript file (yeah yeah i know i'm dumb). Still, it turned out alright!

Testing again in the chrome console, neither worked well with ng-repeat. If you wanna render your list with ng-repeat convert your json array back to javascript array with JSON.parse(foo) for example.
