Question

I use the following code for inserting data to json:

categories: [
                'Tokyo',
                'Jakarta',
                'New York',
                'Seoul',
                'Manila',
                'Mumbai',
                'Sao Paulo',
                'Mexico City',
                'Dehli',
                'Osaka',
                'Cairo',
                'Kolkata',
                'Los Angeles',
                'Shanghai',
                'Moscow',
                'Beijing',
                'Buenos Aires',
                'Guangzhou',
                'Shenzhen',
                'Istanbul'
            ],

It works, but, i want to put this data into an array or string variable like this:

var data = Array('Tokyo',
                'Jakarta',
                'New York',
                'Seoul',
                'Manila',
                'Mumbai',
                'Sao Paulo',
                'Mexico City',
                'Dehli',
                'Osaka',
                'Cairo',
                'Kolkata',
                'Los Angeles',
                'Shanghai',
                'Moscow',
                'Beijing',
                'Buenos Aires',
                'Guangzhou',
                'Shenzhen',
                'Istanbul');
categories: [data],

But, It does not work. Can you help me ?
Thanks.

Answer 1

data: ['Tokyo', 'Jakarta',...] 

is already an array which is part of an object. if you want it as separate variable just create it like this:

var data = ['Tokyo', 'Jakarta',...];

and add it to your object

var yourObject = {categories: data};

you could even do stuff like this:

var yourObject = {categories: new Array('Tokyo', ...)};

but please use the bracket notation

hint: you are creating an “object literal” not a JSON-Object. JSON is just a subset of the object literal. read more here
