A Prompt dialog box is very useful when we want to pop-up a text box to get user input. User needs to fill the text box field and then click OK.
A Prompt dialog box is displayed using a method prompt(). The prompt method takes two parameters:
1. A label which you want to display
2. A default string to display in the text box
A Prompt dialog box gives two buttons:
1. A label which you want to display
2. A default string to display in the text box

1. OK - If a user clicks the OK button, prompt() method returns a value from a text box
2. Cancel - If a user clicks the Cancel button, the prompt() method returns a null value
2. Cancel - If a user clicks the Cancel button, the prompt() method returns a null value
