jsrender helpers template - convert int variable to string

Lukerayn3r

Hello, I am passing some data into my template and some of the data are long integers which i want to convert into strings.

I read through the following documentation - https://jsreport.net/learn/handlebars

I followed the helper example where you convert a string to uppercase, that works perfectly. I created a new helper -

function convetToString(str) {
    return str.toString();
}

and in the template wrote the following {{{convetToString 100000}}}

Problem 1: I want the output to be 100,000 but instead it just outputs 100000.

Problem 2: once problem 1 is fixed instead of {{{convetToString 100000}}} i want to put {{{convetToString data.number}}} but that throws the following error

Error while executing templating engine. Cannot read property 'toString' of undefined. Error on line 24:16.

  23 | function convetToString(str) {
> 24 |     return str.toString();
     |                ^
  25 | }
  26 | 
  27 | function toUpperCase(str) {

I have also tried this using {{{toUpperCase name}}} (name is one of the values i passed through in the data) and i get the same error even though that function works if i put {{{toUpperCase "Luke Rayner"}}}

Please try to share the whole example in playground

Your data.number doesn't exists likely.

For formatting numbers, you probably want to use a library like numeraljs
