Never got javascript Namespaces. Doesn't seem to work

Posted on by MikeC282 2,095

Hi all,

So I've constantly read that namespacing is important in javascript web resources but it never seems to work for me. Everytime I try to namespace something it always says the javascript function doesn't exist....

So for example if I want to trigger a function on javascript load, below is my sample web resource code:

let Sdk = Sdk || {}; //Create namespace

Sdk.testFunction = function name(executionContext) {

    let formContext = executionContext.getFormContext();
    // Get Record ID
    let recordId = formContext.data.entity.getId();
    // console log record ID
    console.log(recordId);
    
}

So the function I then trigger on load is Sdk.testFunction

But when I reload the Dynamics form it throws a error that this function doesn't exist.

Just confused. Do I need to wrap this in a IIFE?

    because let is scoped

    Thank you kind sir! That worked perfectly.

    Another question. Why can't we declare namespaces using let? I've been trying to move all my code to ES6 and above these days and just curious why let wouldn't.

    afaik you can't use let to define a namespace, you need to use var

    also you have "name" after function that is not correct, this code should work:

    var Sdk = Sdk || {}; //Create namespace

Sdk.testFunction = function(executionContext) {
    let formContext = executionContext.getFormContext();
    // Get Record ID
    let recordId = formContext.data.entity.getId();
    // console log record ID
    console.log(recordId);
    
}
