There are three types of alerts you can use:
-Confirm Alert: A confirm alert will display a message with an “OK” and “Cancel” button. The user will have to click either the “OK” or “Cancel” button to continue.
-Prompt Alert: A prompt alert will display a message with an input field and an “OK” button. The user can enter some text into the input field and then click the “OK” button to continue.
Alerts are generally used for debugging purposes, but they can also be used for important messages that you want the user to see.
An alert is a message that pops up on the screen to give the user some information or to ask them to do something. Alerts are created using the Alert class.
There are four ways to create an alert:
1. Use the alert() method:
alert(“I am an alert”);
2. Use the assert() method:
assert(true,”I am an alert”);
3. Use the confirm() method:
confirm(“I am an alert”);
4. Use the prompt() method:
prompt(“I am an alert”);
Here’s the full code for a basic alert box:
You can also add HTML tags to your alert message:
An alert box is often used if you want to make sure information comes through to the user. When an alert box pops up, the user will have to click “OK” to proceed.
Here is an example of an alert box:
A confirm box is often used if you want the user to verify or accept something. When a confirm box pops up, the user will have to click either “OK” or “Cancel” to proceed. If the user clicks “OK”, the box returns true. If the user clicks “Cancel”, the box returns false.
Here is an example of a confirm box:
A prompt box is often used if you want the user to input a value before proceeding. When a prompt box pops up, the user will have to click either “OK” or “Cancel” to proceed after entering an input value. If the user clicks “OK”, the box returns the input value. If the user clicks “Cancel”, the box returns null.
Here is an example of a prompt box:
-Use alerts sparingly. If you use too many alerts, users will start ignoring them. Use them only when absolutely necessary.
-Make sure the message is clear and concise. Avoid using long, complicated messages.
-Make sure the alert is triggered at an appropriate time. Don’t trigger an alert too early or too late in the user’s interaction with your website or app.
-Allow users to dismiss the alert if they wish. Don’t force them to interact with the alert if they don’t want to.
