how to insert text into json using jquery/javascript [duplicate]

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(', ');

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.

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.
