NEW QUESTION # 46
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.
Answer:
Explanation:
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:

NEW QUESTION # 47
Which two functions support 2D transformations in CSS3? Choose 2.
Answer: A,D
Explanation:
The correct 2D transformation functions are matrix() and skew(). CSS transformations are applied through the transform property, which accepts transform functions that can move, rotate, scale, skew, or otherwise alter an element visually in two-dimensional or three-dimensional space. MDN describes the < transform-function > type as representing transformations that affect an element's appearance and can operate in 2D or 3D space.
The matrix() function is valid because it defines a homogeneous two-dimensional transformation matrix, allowing multiple transform effects to be represented in a single function. The skew() function is also valid because it distorts an element along the 2D plane. move() is not a CSS transform function; the standard movement function is translate(). scroll() is not a transform function; scrolling is controlled through overflow and scroll APIs. zoom() is not a CSS3 2D transform function. References/topics: CSS3 transforms, transform property, 2D transformation functions, matrix(), skew().
NEW QUESTION # 48
Which three methods are associated with the HTML5 localStorage API? Choose 3.
Answer: B,C,D
Explanation:
The correct methods are setItem(), removeItem(), and clear(). The HTML5 Web Storage API exposes localStorage as a persistent key-value storage object for the current origin. Data stored in localStorage remains available after page reloads and browser restarts unless it is explicitly removed or cleared. setItem (key, value) stores a value under a named key or updates the value if the key already exists. removeItem(key) deletes one specific key-value pair from storage. clear() removes all key-value pairs from the storage object for that origin. These methods are part of the standard Storage interface used by both localStorage and sessionStorage. write is not a Web Storage method; it is associated with document-writing behavior, not application state storage. cookie is also incorrect because cookies are a separate browser storage mechanism accessed through document.cookie, not a method of localStorage. References/topics: Web Storage API, localStorage, Storage interface, application state, persistent key-value data.
NEW QUESTION # 49
You need to ensure that the value of an input element is a valid 10-digit phone number with no symbols. The input element should initially display all zeroes, but that value should never be stored with the form.
Complete the markup by selecting the correct option from each drop-down list.
Answer:
Explanation:
Explanation:
< input id= " phone "
pattern= " [0-9]{10} "
placeholder= " 0000000000 " >
The correct first attribute is pattern because the requirement is to validate the entered value against a specific format: exactly ten numeric digits and no symbols. The regular expression [0-9]{10} means that only digits from 0 through 9 are allowed, and exactly ten of them must be entered. This prevents values such as 123-456-
7890, (123)4567890, or 123 456 7890 because those contain symbols or spaces. The correct second attribute is placeholder, not value, because the input should initially display all zeroes but that displayed text must not be submitted or stored with the form. A placeholder is hint text shown when the field is empty; it disappears when the user enters real data and is not submitted as the control's value. By contrast, value= " 0000000000 " would actually prepopulate the input and could be submitted if the user did not change it. The required option is not selected because the question focuses on format validation and display hint behavior, not mandatory completion. References/topics: HTML5 form validation, pattern, regular expressions, placeholder, input constraint validation.
NEW QUESTION # 50
You are creating a script that reads a JSON menu file and displays the Entree, Price, and Description.
Complete the code by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct selection.
Answer:
Explanation:
Explanation:
First drop-down: var xhr = new XMLHttpRequest();
Second drop-down: if(xhr.status===200){
Third drop-down: responseObject = JSON.parse(xhr.responseText);
The script must first create an XMLHttpRequest object, so the correct first selection is var xhr = new XMLHttpRequest();. This object performs the asynchronous request for menu.json. After the request finishes, the onload callback executes. The response should be processed only when the request succeeds, so the correct status check is if(xhr.status===200){; HTTP status 200 means the file was successfully retrieved.
Status codes 403, 404, and 500 represent forbidden access, missing resource, and server error conditions, so they are not appropriate for normal JSON processing. The JSON file is returned as plain text through xhr.
responseText, so it must be converted into a JavaScript object with JSON.parse(xhr.responseText). Once parsed, the code can access responseObject.menu[i].Entree, Price, and Description inside the loop and build the display output. responseXML is incorrect because the source file is JSON, not XML.
