Question

Simple question –

How do I convert a string that has been through parseInt back to it’ string value?

var myInt = parseInt('J', 36); //19
var myString = myInt.toString(); //returns "19" I would like it to return "J"

Can I do it with longer strings?

var myInt = parseInt("Jon o'reiley", 36); //25511

Answer 1

When converting a string to an int, information of the base the string used is lost. Also any data that was ignored while parsing is lost.

However, just like parseInt toString has a base argument, too:

myInt.toString(36);

Demo from the JS shell:

js> (19).toString(36)
"j"
js> parseInt('abc+foo', 36).toString(36)
"abc"
