How can I convert this json

{
    "dates": [
        "12-10-2012",
        "12-11-2012",
        "13-11-2012",
        "22-11-2012",
        "23-11-2012",
        "2-12-2012"
    ]
}

into an array like this

var array = ["12-10-2012", "12-11-2012", "13-11-2012", "22-11-2012", "23-11-2012", "2-12-2012"]

</div>

What you have is an object that contains the array. All you have to do is get the value of the object using key dates.

Assuming a var defined for data like below,

var data = {
    "dates": [
        "12-10-2012",
        "12-11-2012",
        "13-11-2012",
        "22-11-2012",
        "23-11-2012",
        "2-12-2012"
    ]
}

then data['dates'] will return you that array.

just use the dates variable itself

var json = { ... your json ...}
var array = json.dates;

the dates property inside your json is an array already

Parse the JSON and get the dates property:

var array = $.parseJSON(theJsonString).dates;

What you want to do is called parsing. Some browsers, like Chrome have this native function

 var obj = JSON.parse(string)

But if you use jQuery, you can use

var obj = $.parseJSON(string)

This will give you an object. You can then do

obj.dates
