Alert prompt confirm part 2

Prompt Box



A prompt box is often used to have the user input a value before entering a page.
When a prompt box pops up, the user will have to click either OK or Cancel to proceed after entering the input value.

The prompt() method takes two parameters. 
- The first is the label, which you want to display in the text box.

var user = prompt("Please enter your name");
alert(user);Try It Yourself

When a prompt box pops up, the user will have to click either "OK" or "Cancel" to proceed after entering an input value. Do not overuse this method, because it prevents the user from accessing other parts of the page until the box is closed
