How to insert text into json array using jquery/javascript .

supposing I have data as

some numbercodes in a text file format 123, 456, 789

I want to get them in a json array format using javascript/jquery.

var nuumbercodes = [ "123","456","789" ];

Answer 1

If you have a well formatted text string with comma separated numbers,
like this '123,456,789'

This should have no spaces or tabs,
Then you can convert it simply into a JavaScript array.

var myTextwithNuumbercodes='123,456,789';

var numbercodes=myTextwithNuumbercodes.split(',');

returns ['123','456','789']

if you have a JSON string like this '[123,456,789]' then you get a javascript array by calling JSON.parse(theJSONString)

var numbercodes=JSON.parse('[123,456,789]');

returns [123,456,789]

notice the "[]" in the string ... that is how you pass a JSON array toconvert it back to a string you can use JSON.stringify(numbercodes);

if you have a total messed up text then it's hard to convert it into a javascript array but you can try with something like that

var numbercodes='123, 456, 789'.replace(/\s+/g,'').split(',');

this firstly removes the spaces between the numbers and commas and then splits it into a javascript array

in the first and last case you get a array of strings u can transform this strings into numbers by simply adding a + infront of them if you call them like

mynumbercode0=(+numbercodes[0]);// () not needed here ...

in the 2nd case you get numbers

if you want to convert an array to a string you can also use join();

[123,456,789].join(', ');

Answer 2

Assuming your data is in a string, then split it on commas, use parseInt in a for loop to convert the string numbers into actual Numbers and remove the whitespace, then JSON.stringify to convert to JSON.

Answer 3

You could use .push() push values at the end of an array. After that you could use JSON.stringify(nuumbercodes) to make a JSON string representation of your Array.
