I have tried looking on the Mozilla JSON stringify page of their docs as well as here on SO and Google but found no explanation. I have used JSOn stringify much time but never come across this result
I have an array of JSON objects
[
{
"param_2": "Description 1",
"param_0": "Name 1",
"param_1": "VERSION 1"
},
{
"param_2": "Description 2",
"param_0": "Name 2",
"param_1": "VERSION 2"
},
{
"param_2": "Description 3",
"param_0": "Name 3",
"param_1": "VERSION 3"
}
]
attached to my $scope and in order to POST them as one parameter, I used the JSON.stringify() method and I get the following:
[
{
"param_2": "Description 1",
"param_0": "Name 1",
"param_1": "VERSION 1",
"$$hashKey": "005"
},
{
"param_2": "Description 2",
"param_0": "Name 2",
"param_1": "VERSION 2",
"$$hashKey": "006"
},
{
"param_2": "Description 3",
"param_0": "Name 3",
"param_1": "VERSION 3",
"$$hashKey": "007"
}
]
I am just curious what exactly is the $$hashkey as I expected something more similar to the following from the stringify method:
[
{
"1":{
"param_2": "Description 1",
"param_0": "Name 1",
"param_1": "VERSION 1"
},
"2":{
"param_2": "Description 2",
"param_0": "Name 2",
"param_1": "VERSION 2"
},
"3":{
"param_2": "Description 3",
"param_0": "Name 3",
"param_1": "VERSION 3"
}
}
]
I am not sure if it is a factor but I am using Angularjs 1.1.5, JQuery 1.8.2 and Spring 3.0.4 and Spring security 3.0.7 on the Server-side
It is not causing me any issues but I would like to know the cause and reason for the $$hashkey
