The value of your message_array property is a quoted string, not an object.
Note what $.each is giving you: every character of the string.
How are you generating the JSON data? That's where you need to fix this.
With the extra newlines removed, your JSON data looks like this:
{
"processed": false,
"message": "External link could not be set:",
"message_array": "{\"link\":{\"isEmpty\":\"Value is required and can't
be empty\"}}"
}
It should look like this:
{
"processed": false,
"message": "External link could not be set:",
"message_array": {
"link": {
"isEmpty": "Value is required and can't be empty"
}
}
}
The newlines and indentation are not significant (except inside a string).
