Intl-tel-input javascript library in Aura Component

753    Asked by AnkitChauhan in AWS , Asked on Jul 12, 2021

So I have a requirement in Aura Component were in, I need to create an international telephone input field. I found this library called but I'm having issues trying to implement it. One of the requirements to implement this field is to load the javascript file utils.js for me to call validation/formatting methods already available in the library.

What i'm doing so far is present in the code below

Component :

Controller after script is loaded method :
$A.createComponent( "ltng:require", { "scripts": $A.get('$Resource.int_tel_input') + '/js/utils.js', "afterScriptsLoaded" : component.getReference('c.submit') }, function(newRequire,status, errorMessage){ if (status === "SUCCESS") { console.log('Success - > '); var body = component.get("v.body"); body.push(newRequire); component.set("v.body", body); console.log(component.get('v.body')); } } );
javascript function from library that is throwing an error.
var injectScript = function injectScript(path, handleSuccess, handleFailure) { // inject a newscript element into the page var script = document.createElement("script"); script.onload = function() { forEachInstance("handleUtils"); if (handleSuccess) handleSuccess(); }; script.onerror = function() { forEachInstance("rejectUtilsScriptPromise"); if (handleFailure) handleFailure(); }; script.className = "iti-load-utils"; script.async = true; script.src = path; document.body.appendChild(script); };
AfterScriptsLoaded is not being called so I'm sure there's something wrong with the way I try to load the javascript library.
Any tip is appreaciated or can someone point me in the right direction who have implemented this library before in Aura Component. How to create intltelinput ?

Follow the steps below:

To create intl-tel-input, you need to embed the intl-tel-input plugin in your code.
