NEW QUESTION # 43
Move the appropriate attributes from the list on the left to the correct descriptions on the right. You may use each attribute once, more than once, or not at all.
Note: You will receive partial credit for each correct match.
Answer:
Explanation:
Explanation:
pattern # Provides a way to set a regular expression that the value must match placeholder # Provides a way to set default text that displays until focus is placed in an element required # Provides a way to set form elements as mandatory multiple # Provides a way to allow more than one file or email address in a single input The correct matches are based on standard HTML5 form validation and input-attribute behavior. The pattern attribute defines a regular expression that the input value must satisfy before the form can be submitted successfully. It is commonly used for structured values such as phone numbers, codes, postal formats, or custom identifiers. The placeholder attribute supplies short hint text inside an input field, helping the user understand the expected value before entering data. The required attribute makes a form control mandatory; if the field is empty, constraint validation prevents successful submission. The multiple attribute allows a single input to accept more than one value, specifically for controls such as input type= " file " and input type= " email " , where users may upload multiple files or enter multiple email addresses. The maxlength attribute is not used in these matches because it limits the maximum number of characters that can be entered, but none of the listed descriptions asks for character-length restriction. References/topics: HTML5 form attributes, constraint validation, pattern, placeholder, required, multiple, input validation.
NEW QUESTION # 44
Review the following markup segment:
< form action= " process.js " method= " get " >
< label for= " secretcode " > Secret Code < /label >
< input type= " text " name= " secretcode "
pattern= " [a-zA-Z]{4}-[0-9] {2}-[0-9]{4}-[a-zA-Z] {4} "
placeholder= " secretcode " >
< input type= " submit " value= " Submit " >
< /form >
Which entry will validate successfully according to the required pattern?
Answer: B
Explanation:
The correct answer is D because the pattern attribute requires the exact structure defined by the regular expression [a-zA-Z]{4}-[0-9] {2}-[0-9]{4}-[a-zA-Z] {4}. The first group, [a-zA-Z]{4}, requires exactly four alphabetic characters. The second group, [0-9] {2}, requires exactly two numeric digits. The third group, [0-9]
{4}, requires exactly four numeric digits. The final group, [a-zA-Z] {4}, requires exactly four alphabetic characters. Hyphens must appear between each group. Option D, kukX-34-4938-WJDF, satisfies every part:
kukX is four letters, 34 is two digits, 4938 is four digits, and WJDF is four letters. Option A fails because Uhj6 contains a digit in the final letter-only group. Option B fails because y7Ts contains a digit in the first group and A3 is not two digits. Option C fails because 23h contains a letter and breaks the two-digit group.
References/topics: HTML5 input validation, pattern attribute, regular expressions, form constraint validation.
NEW QUESTION # 45
Which two code segments declare a JavaScript method? Choose 2.
Answer: A,D
Explanation:
The correct selections are B and C because both define a function as a member of an object context, which is the essential JavaScript pattern for declaring a method. MDN defines a method as a function that is a property of an object. It also shows that a function expression can be assigned to a variable or property and then invoked later. In option B, Score: function() { ... } represents an object-literal method property. This pattern is commonly used when defining custom objects, prototypes, configuration objects, or class-like structures in JavaScript. In option C, this.Score = function() { ... } assigns a function to the current object instance, creating an instance method that can be called through that object. Option A does not declare a method; as written, it is only an invalid or incomplete variable assignment and does not use the function keyword or method syntax.
Option D invokes Score() and assigns its return value to a; it calls a function rather than declaring a method.

NEW QUESTION # 46
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.
Answer:
Explanation:
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.
NEW QUESTION # 47
Which three methods are associated with the HTML5 localStorage API? Choose 3.
Answer: A,C,E
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.
