    Add WaitingPopup Widget

    To render the ejWaitingPopup using aurelia directive, we need to inject the ej aurelia directive with modules.

    In a real-time login page scenario, when you click the Login button, the WaitingPopup is displayed.

  • js
  • export class DefaultFunctionalities { 
     constructor() {}
     onOpen(args) {
    	 $("#popup").ejWaitingPopup({
                    showOnInit: true,
                    target: "#targetElement"
                });
                function success() {
                    let obj = $("#popup").data("ejWaitingPopup");
                    alert("Signed in successfully");
                    obj.hide();
                }
    			setTimeout(success, 5000);
                 
    }
    }

    The following screenshot shows the output of the above code example.
