Help with auto increment a value in a catalog item variable

SD29 · ‎04-24-2019

Hello All,

I am trying to populate 2 variables by concatenating & incrementing 4 different variables using onChange client script based on a Quantity variable.

Variables: A,B,C,D,E,F

A,B,C are reference fields

D is a single line text with default value as '00'.

If the Quantity is 1 then the variable E will be populated as ABC00

If the Quantity is 2 then the variable F should be populated as ABC01, but the script i'm using is populating the variable as ABC1 instead of ABC01.

please let me know where i'm doing mistake.

Script:

var qt = g_form.getValue('a');
var en = g_form.getValue('b');
var eco = g_form.getValue('c');
var it = g_form.getValue('d');
var hn = en + eco + it;
if(qt == 1){
g_form.setValue('e', hn);
}
var it2 = ++it;
var hn2 = en + eco + it2;
if(qt == 2){
g_form.setValue('d', hn);
g_form.setValue('e', hn2);
}

Thanks,

SD

If you need to use numbers and store them in a field with padded zeroes, you can write a function like this:

function padWithZeroes(number, len) {
   var output = number.toString();
   while (output.length < len) {
       output = "0" + output;
   }
   return output;
}

var test = padWithZeroes(13, 5); // test equals "00013"

You only call padWithZeroes() on the number part (such as it2) and set it to the desired length of the zero-padded string:

var numericPart = padWithZeroes(it2, 2); // turns 2 into "02", 5 into "05", etc.
