Requirement: I have an Oracle APEX page. On that page I have button on click of which I want to show the Alert Message.

Sample screen is shown below:

Solution: For solution of the above requirement I will be discussing here two approaches. Off course there are many more approaches by which we can show the Alert Message.

Approach 1: Show Alert Message by using Alert Action

Step 1: Create a button with the below properties

• Button Name: P3_SHOW_ALERT_MSG_DA
• Label: Show Alert Message by using Alert Action

Step 2: Create the Dynamic Action and set the below properties:

• Name: Show Alert Message by using Alert Action
• Event: Click
• Selection Type: Button
• Button: P3_SHOW_ALERT_MSG_DA

Step 3: Set the properties of the True outcome as below:

• Action: Alert
• Text: Hello &APP_USER. I am called using Alert Action

Here &APP_USER. will dynamically pick the Login User Name.

Approach 2: Show Alert Message by using JavaScript

Step 1: Create a button with the below properties

• Button Name: P3_SHOW_ALERT_MSG_JAVASCRIPT
• Label: Show Alert Message by using JavaScript

Step 2: Create the Dynamic Action and set the below properties:

• Name: Show Alert Message by using JavaScript
• Event: Click
• Selection Type: Button
• Button: P3_SHOW_ALERT_MSG_JAVASCRIPT

Step 3: Set the properties of the True outcome as below:

• Action: Execute JavaScript Code
• Code:

apex.message.alert("Hello &APP_USER.. I am called using JavaScript");

Here &APP_USER. will dynamically pick the Login User Name.

Save and run the application. Thus, the ran application is shown below:

Let us now click on the “Show Alert Message by using Alert Action” button and with that throws an Alert with the message as “Hello [email protected] I am called using Alert Action“

Let us now click on the “Show Alert Message by using JavaScript” button and with that throws an Alert with the message as “Hello [email protected]. I am called using JavaScript“

Hence, the solution to our requirement.
