Quiz On JavaScript Skills! Trivia

The correct answer is ".Js" because JavaScript files typically have a file extension of ".js". This file extension helps to identify and differentiate JavaScript files from other types of files.

When a button is clicked, the event handler associated with that button is invoked. In this case, the correct answer is "Onclick()" because it represents the event that is triggered when the button is clicked. The other options, "OnSubmit()", "OnLoad()", and "IsPostBack()", do not specifically refer to the event of clicking a button.

The isNaN() function is used to determine if a given value is not a number. It returns true if the value is not a number and false if it is a number. This function is often used to validate user input in forms or to check if a mathematical operation resulted in a valid number.

A function associated with an object is called a method. In object-oriented programming, methods are functions that are defined within a class and are used to perform specific actions or operations on the object. Methods can access and manipulate the data within the object, and they are typically called using the object's name followed by the method name, using the dot notation.

The prompt() dialog box displays a message and a data entry field. This allows the user to enter some input in response to the message displayed. The other options, such as alert(), confirm(), and msg(), do not have a data entry field and are used for displaying messages or asking for confirmation from the user.

The getMonth() function returns the month as an integer. This means that the value returned by the function will be a whole number representing the month, such as 1 for January, 2 for February, and so on. It will not return a float (decimal number), character, or string.

The method Prompt() contains two parameters.

The onBlur() event is used to check if a text box is empty when the user moves away from it. This event is triggered when the user clicks outside of the text box or tabs away from it. It allows for validation or any other action to be performed to ensure that the text box is not left empty. The onClick() event is triggered when the user clicks on the text box, OnFocus() event is triggered when the text box receives focus, and "None" indicates that none of these events are used to check an empty text box.

Int.Parse is the correct answer because it is a function that is used to convert a string to an integer. By using Int.Parse, you can take a string input and convert it into an integer data type. This function is commonly used in programming languages to handle situations where you need to convert user input or data from a file into numerical values for calculations or comparisons.

The "caption" tag is used to provide a heading or title to a table. It is typically placed at the top of the table and helps to provide a brief description or summary of the table's content. This tag is used to improve the accessibility and understanding of the table for users.

The correct answer is "script". This is because the "script" element is specifically designed to hold JavaScript code within an HTML document. It is used to embed or reference external JavaScript files, or to directly include JavaScript code within the HTML file itself.
