44. Frage
You want to display a message box showing the user ' s current latitude and longitude as identified by the user' s browser.
Complete the code by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct selection.
Antwort:
Begründung:
Explanation:
First drop-down: navigator.geolocation
Second drop-down: navigator.geolocation
Third drop-down: getCurrentPosition(showLocation)
The correct API object is navigator.geolocation because browser-based geographic location is exposed through the Geolocation API, not through window.location. window.location represents the current page URL and navigation state; it does not provide latitude or longitude. The first selection checks whether the browser supports geolocation by evaluating navigator.geolocation. Inside the block, the same object must be used to request the user's current position. The correct method is getCurrentPosition(showLocation), which requests the device's current location and passes a position object to the callback function when the location is available. The callback then reads position.coords.latitude and position.coords.longitude and displays those values with alert(). The alternatives that pass window.location are incorrect because they provide page- location information rather than geographic coordinates. The alternatives that call showLocation(...) directly are also incorrect because the browser must first retrieve the actual position object. References/topics:
Geolocation API, navigator.geolocation, getCurrentPosition(), callback functions, latitude and longitude.
45. Frage
Review the images on the left.
Complete the statements by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct selection.
Antwort:
Begründung:
Explanation:
First drop-down: flex boxes
Second drop-down: background-size
Third drop-down: cover
The correct layout mechanism is responsive flex boxes because the content changes from a vertical mobile arrangement to a wider multi-column layout as space becomes available. Flexbox supports this behavior naturally through flexible item sizing and wrapping, often without needing explicit media queries for every screen size. The header image must fill its visible header region on both mobile and desktop. The correct CSS property for controlling how a background image scales inside its container is background-size. The correct value is cover, because background-size: cover scales the image so that the entire container is covered while preserving the image's aspect ratio. This prevents distortion, although some cropping can occur when the image and container have different aspect ratios. contain would preserve the full image but may leave empty space. auto would use the image's intrinsic size and would not reliably fill the header area. background- attachment, background-clip, and background-repeat do not control image scaling.
46. Frage
You write the following JavaScript code. Line numbers are included for reference only.
01 < script >
02
03 beststudent = new Student( " David " , " Hamilton " );
04 document.write(beststudent.fullname + " is registered. " );
05 < /script >
You need to write a function that will initialize and encapsulate the member variable fullname.
Which code fragment could you insert at line 02 to achieve this goal?
Note: Each correct answer presents a complete solution.
Antwort: B
Begründung:
The correct answer is A because the code at line 03 creates an object by calling a constructor function with the new keyword. A constructor function must be declared with the same identifier used in the new Student( " David " , " Hamilton " ) expression. Inside the constructor, instance members should be assigned through this, because this refers to the newly created object. Option A correctly initializes this.firstname, this.lastname, and this.fullname, so beststudent.fullname is available at line 04 and evaluates to " David Hamilton " . Option B is invalid JavaScript syntax because var student(firstName, lastName) is not a valid function declaration. Option C is also invalid syntax for the same reason: var Student(firstname, lastname) cannot declare a constructor.
Option D uses a valid function declaration, but it assigns firstname, lastname, and fullname without this, which creates or references non-encapsulated variables rather than properties of the constructed object.
References/topics: JavaScript constructor functions, new keyword, object instance properties, this, custom classes.
47. Frage
You need to draw a blue rectangle that meets these conditions:
* It is 200 by 200 pixels.
* It contains a white circle that is centered within the rectangle.
* The circle has a 50-pixel radius.
* The image should appear as follows: a blue square with a centered white circle.
Refer to the image on the left.
You need to ensure that the image scales without distortion when the page is resized. You must not be required to use JavaScript.
Complete the code by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct selection.
Antwort:
Begründung:
Explanation:
First blank: < svg width= " 200 " height= " 200 " >
Second blank: < rect width= " 200 " height= " 200 "
Third blank: < circle cx= " 100 " cy= " 100 " r= " 50 "
Fourth blank: < /svg >
The correct solution uses SVG because SVG graphics are vector-based and can scale without pixel distortion when the page or viewport changes. A < canvas > element would require script-based drawing logic, which violates the requirement that JavaScript must not be required. An < img > or < picture > element can display an image, but those options do not define the rectangle and circle directly in markup. The outer container must therefore be < svg width= " 200 " height= " 200 " > . The blue square is created with < rect width= " 200 " height= " 200 " fill= " blue " / > , which produces a rectangle matching the required 200-by-200 dimensions.
The centered white circle must use SVG circle geometry: cx= " 100 " and cy= " 100 " place the center at the midpoint of the 200-by-200 square, and r= " 50 " creates the required 50-pixel radius. The final closing tag must be < /svg > .
48. Frage
The following code adds items to the groceries array from the other arrays. Line numbers are for reference only.
01 < body >
02 < p id= " list " > < /p >
03 < script >
04 var groceries = [];
05 var dairy = [ " Milk " , " Eggs " , " Cheese " , " Ice Cream " ];
06 var beverages = [ " Juice " , " Water " , " Soda " , " Coffee " ];
07 var fruits = [ " Apples " , " Bananas " , " Grapes " , " Oranges " , " Strawberries " ];
08 var vegetables = [ " Broccoli " , " Carrots " , " Lettuce " , " Spinach " , " Tomatoes " ];
09 var meats = [ " Beef " , " Chicken " , " Pork " ];
10
11 function addVegetables() {
12 groceries = groceries.concat(vegetables);
13 }
14
15 function addFruits() {
16 groceries = groceries.concat(fruits);
17 }
18
19 function addOther() {
20 groceries.push(meats[1]);
21 groceries.push(dairy[3]);
22 }
23
24 fruits.shift();
25 addVegetables();
26
27 groceries.shift();
28 addFruits();
29
30 groceries.pop();
31 groceries.shift();
32
33 addOther();
34 document.getElementById( " list " ).innerHTML = groceries;
You need to debug the code on the left to determine how many items are in the groceries array at the specified breakpoints.
Evaluate the code and answer the questions by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct answer.
Antwort:
Begründung:
Explanation:
Line 26 drop-down: 5
Line 29 drop-down: 8
Line 32 drop-down: 6
The groceries array starts empty. Line 24 runs fruits.shift(), which removes " Apples " from the fruits array.
This leaves four fruits, but it does not add anything to groceries. Line 25 calls addVegetables(), which executes groceries = groceries.concat(vegetables);. Since vegetables contains five items, groceries contains 5 items at line 26. Line 27 then executes groceries.shift(), removing the first item from groceries and reducing the count to 4. Line 28 calls addFruits(), which appends the four remaining fruits, increasing the array count to 8; therefore, line 29 is 8. Line 30 executes groceries.pop(), removing the last item and reducing the count to
7. Line 31 executes groceries.shift(), removing the first item and reducing the count to 6. Therefore, line 32 is
6. The addOther() function on line 33 has not executed yet at the line 32 breakpoint. References/topics:
JavaScript arrays, debugging breakpoints, concat(), shift(), pop(), push(), array item counting.
