I have Invoice Form
in my POS System.
And I would like to auto generate Ref number + 1
base on the latest one.
Ex:
1- Latest: INV001
, -> INV002
2- Latest: IVN001-BB005
, -> IVN001-BB006
3- Latest: BB005CC002
DD -> BB005CC003
DD
Easiest way is to just set it on the document before you insert
could example?
(how to replace last of string)
Now work fine with
String.prototype.replaceLast = function(what, replacement) {
var pcs = this.split(what);
var lastPc = pcs.pop();
return pcs.join(what) + replacement + lastPc;
};
----
str.replaceLast(what, replacement)
If the number to change will be in a consistent/know/given location you could do :
someIdString[locationtoreplace] = parseInt(someIdString[locationtoreplace])++;
