How to pass data with a 'function' as value to the template?

[liwonder]

Say I got some data in function beforeRender like this:

req.data.myData = {
name: 'test',
formatter: function(value) {
return '$' + value;
}
}

How can I get the function pass into the template?

hi @liwonder you can define those functions as helpers in your templates, and you can use the helpers inside your template, quick playground for demonstration: https://playground.jsreport.net/studio/workspace/BJP7eMYTe/6

Thanks for your reply and that make sense! But now the situation I am facing is that I got ten or more children templates which will probably use this same function in the future, so I should copy and paste ten times, this is clearly not a good solution. If I want to make some changes with the function in the future, that would be a unwise move. Thanks!

@liwonder i didn't know your use case, but nothing that assets extension can't solve, here you have the same example updated sharing helpers between templates -> https://playground.jsreport.net/studio/workspace/BJP7eMYTe/10
