Transforming JSON data into a JavaScript array

Question

Transforming JSON data into a JavaScript array

The JSON data I am receiving has commas in it, making it a bit challenging to convert it into a JavaScript array. Here is an example of the incoming data:

var data = '["QUAIL, TX","QUAKER CITY, OH","QUAKER, CT","QUAKER STREET, NY"]';

I have attempted to use JSON.parse(data) and splitting the data by '",' but both methods are not giving me the desired output. Any suggestions on the best approach to handle this? It seems like converting it into a JavaScript array is trickier than expected.

     data = JSON.stringify(data);
     data = data.split('",');

PS: Despite researching similar questions, I have not found a solution that fits my specific scenario.

Answer №1

Using commas in a JSON string does not trigger an exception when parsed with JSON.parse(). Consider the following example:

var data = '["NEW YORK, NY","LOS ANGELES, CA","CHICAGO, IL","HOUSTON, TX"]';
var parsedData = JSON.parse(data);
alert(parsedData[0]);

Try it on JSFiddle: http://jsfiddle.net/eKtPx/

The issue with your code may lie elsewhere.

It appears that this solution works as intended, with the assumption that the data structure provided is consistent. If the JSON format varies, the code below may not function correctly.

var data = ["QUAIL, TX","QUAKER CITY, OH","QUAKER, CT","QUAKER STREET, NY"].toString().split(',');

 //Output: ["QUAIL", " TX", "QUAKER CITY", " OH", "QUAKER", " CT", "QUAKER STREET", " NY"]

If you wish to remove the white space:

var data = ["QUAIL, TX","QUAKER CITY, OH","QUAKER, CT","QUAKER STREET, NY"].toString().replace(/\s/g,'').split(',');
     // Output: ["QUAIL", "TX", "QUAKERCITY", "OH", "QUAKER", "CT", "QUAKERSTREET", "NY"]
