질문 # 11
Which two code segments declare a JavaScript method? Choose 2.
정답：B,C
설명：
The correct selections are C and D because both declare a function as a property of an object, which is the defining characteristic of a JavaScript method. MDN describes a method as a function associated with an object, or more specifically, an object property whose value is a function. In option C, Score: function() { ... } is object-literal syntax. It defines a property named Score whose value is an executable function, so that property behaves as a method of the object. In option D, this.Score = function() { ... } assigns a function to the Score property of the current object instance. MDN notes that this is commonly used inside object methods to refer to the object the method is attached to. Option B does not declare a method; it calls Score() and assigns the return value. Option A is only an incomplete or ordinary variable declaration and does not create a function-valued object property. References/topics: JavaScript objects, custom classes, methods, function expressions, this.
질문 # 12
You create an interface for a touch-enabled application. You discover that some of the input buttons do not trigger when you tap them on the screen. You need to identify the cause of the problem. What are two possible causes? Choose 2.
정답：A,D
설명：
The two likely causes are undersized touch targets and overlapping input regions. Touch input is less spatially precise than mouse input because the contact area of a finger is larger and less exact than a pointer cursor.
Microsoft's touch-target guidance states that interactive UI elements must be large enough for users to access accurately, and recommends a target size around 7.5 mm square, approximately 40 × 40 pixels on a 135 PPI display. Earlier Microsoft touch-design guidance similarly emphasizes that controls must be appropriately sized for touch and identifies approximately 9 mm as a minimum targeting area. Therefore, small input buttons may fail to trigger because the user is not actually hitting the active target area. Overlap is also a valid cause: when two active regions occupy the same physical screen area, hit testing may route the touch to a different element, or the effective target area may be reduced. W3C accessibility guidance explicitly treats overlapping targets as reducing measurable target size unless the overlapping controls perform the same action. Event handlers themselves are not the defect; they are the normal mechanism for processing input.
"Touch screen not initialized" is not a standard HTML5 application cause. References/topics: touch input, event handling, hit testing, target size, overlapping controls.
질문 # 13
You have created custom error messages for a form. When a user attempts to submit the form with invalid data, the data must remain in the form and error messages must be displayed. Which Event property or method should you use?
정답：C
설명：
The correct method is preventDefault(). During form submission, the browser's default behavior is to submit the form to the target URL, which may navigate away from the current page or reload it. If the submitted data is invalid and the application must display custom error messages while preserving the entered values, the submit event handler should call event.preventDefault(). This cancels the default submit action, allowing the page to remain in place and the script to display validation feedback next to the relevant form controls.
defaultPrevented is not the method to use; it is only a Boolean property that indicates whether preventDefault() has already been called. cancelable is also only informational; it tells whether the event's default behavior can be canceled. abort is unrelated to form validation and does not provide the required control over form submission. References/topics: HTML5 form validation, custom validation messages, submit event, event cancellation, preserving form data.
질문 # 14
The following form is missing validation attributes:
< form >
< div class= " container " >
< h1 > Register Here < /h1 >
< p > Please fill in the details to create an account with us. < /p >
< hr >
< label for= " ? " > < b > Enter Email < /b > < /label >
< input type= " ? " placeholder= " Enter Email " name= " ? " placeholder= " username@domain.com " >
< label for= " ? " > < b > Password < /b > < /label >
< input type= " ? " placeholder= " Enter Password " name= " ? " >
< label for= " ? " > < b > Confirm Password < /b > < /label >
< input type= " ? " placeholder= " Confirm Password " name= " ? " >
< label for= " phone " > < b > Phone < /b > < /label >
< input type= " tel " id= " phone " name= " phone " placeholder= " 123-45-678 " >
< hr >
< p > By creating an account you agree to our < a href= " # " > Terms & Privacy < /a > . < /p >
< button type= " submit " class= " registerbtn " > < strong > Register < /strong > < /button >
< /div >
< /form >
You need to update the form to enforce the following requirements for visitors:
* All fields must be completed with valid information.
* The users should not be allowed to type passwords longer than 8 characters.
* Passwords must use only numbers and letters.
* Phone numbers and email addresses must follow the configuration of the placeholder text.
* The browser must display an error message that makes it clear what type of input change is needed.
Review the markup on the left.
Complete the sentences by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct selection.
정답：
설명：
Explanation:
First drop-down: four
Second drop-down: maxlength
Third drop-down: email, password, and phone
The form contains four user-entry input elements: email, password, confirm password, and phone. Since the requirements state that all fields must be completed, the required attribute must be applied to all four inputs.
The password field must prevent entries longer than eight characters, so the correct length-control attribute is maxlength, not max; max applies to numeric/date-style value ranges, while maxlength limits character count in text-style inputs. The phone field also benefits from maxlength because its placeholder format has a fixed visible structure. Finally, completed pattern attributes are needed for email, password, and phone because each has a required format rule: the email must match the placeholder-style address format, the password must use only letters and numbers, and the phone number must follow the placeholder format such as 123-45-
678. The title attribute should accompany these patterns to produce meaningful browser validation messages.
질문 # 15
The ctx variable is the context of an HTML5 canvas object. What does the following HTML markup draw?
ctx.arc(x, y, r, 0, Math.PI, true);
정답：C
설명：
The statement draws a semicircle at the specified point. The arc() method of the Canvas 2D API adds a circular arc to the current path. Its core parameters are the center point x, y, the radius, the starting angle, the ending angle, and an optional direction flag. In this expression, x and y define the center of the arc, and r defines its radius. The start angle is 0 radians, and the end angle is Math.PI radians. Since Math.PI represents
180 degrees, the path covers exactly half of a full circle. The final argument, true, tells the canvas context to draw the arc counterclockwise rather than using the default clockwise direction; however, the angular span remains half of the circumference. The call does not draw a complete visible shape unless the path is later stroked or filled, but the geometric path being created is a semicircular arc. It is not a straight line, square, or full circle. References/topics: Canvas 2D context, arc() method, radians, path construction, drawing arcs and circles.
