P.ej:
<script> var RequestURL = ''; function onWindowClosed(obj) { console.log("callback event : " + JSON.stringify(obj)); if(obj.event_name === event_name) { console.log("successfully returned: " + obj.message); } else { console.log("unknown-event"); } } var userDetails = JSON.stringify({ "appId": ", "customerId": "", }); </script>Puede agregar elementos como scripts u hojas de estilo usando JavaScript de vainilla
var script = document.createElement("script"); script.setAttribute("src", "https://script.example.com/script.js") // Replace with your script link var head = document.querySelector("head") head.appendChild(script)
