How to Display an Alert in Power Apps using JavaScript

When using JavaScript, we can display alerts in model-driven Power Apps. To do this, we can use openAlertDialog.

The syntax for this method looks like below:

Xrm.Navigation.openAlertDialog(alertStrings,alertOptions).then(closeCallback,errorCallback);

As a simple example, we can use:

var alertStrings = { confirmButtonLabel: "Got it", text: "Something happened.", title: "Alert Title" };
var alertOptions = { height: 500, width: 500 };
Xrm.Navigation.openAlertDialog(alertStrings, alertOptions).then(
    function success(result) {
        console.log("Alert dialog closed");
    },
    function (error) {
        console.log(error.message);
    }
);

This displays an alert, with a button “Got it”, an Alert Title and some text “Something happened.”. This may be useful when wanting to alert a user of something when customizing your org.
