問題 #23
You need to contain overflowing text inside the element ' s border without creating unneeded scrollbars or losing text. Which attribute setting should you use?
答案：A
解題說明：
The correct setting is overflow: auto;. The requirement is precise: the text must remain inside the element's border, must not be lost, and scrollbars should not appear unless they are needed. overflow: auto satisfies all three requirements because it clips overflowing content to the element's box and creates scrollbars only when the content actually exceeds the available space. This preserves access to all text while avoiding unnecessary horizontal or vertical scrollbars when the content fits. overflow: hidden is incorrect because it clips the overflowing text and provides no scrolling mechanism, meaning some content may become inaccessible.
overflow: visible is incorrect because the extra text can flow outside the element boundary, violating the requirement to keep content inside the border. overflow: scroll is close but not optimal because it forces scrollbars even when they are not required, which directly conflicts with the instruction to avoid unneeded scrollbars. References/topics: CSS overflow, scroll containers, text containment, content clipping, layout flow.
問題 #24
You need to display the following user interface:
A text input field that displays a selectable suggestion list containing:
Motorcycle
Truck
Boat
Car
Bicycle
答案：
解題說明：
Explanation:
The correct markup uses the HTML5 < datalist > element because the interface shows a text input with a drop- down list of suggested values. The < input > element has list= " vehicles " , which means it must be connected to a < datalist > whose id value is exactly vehicles. This relationship is essential: the list attribute on the input references the id of the datalist that supplies the available options. Each < option > element inside the datalist defines one suggested value: Motorcycle, Truck, Boat, Car, and Bicycle. Unlike a traditional < select > element, a datalist does not restrict the user only to the listed choices; the user can either select an option with the mouse or type directly into the input field. That behavior matches the displayed interface, where the control appears as an editable text box with suggestions. The final closing tag must be < /datalist > because the option elements belong to the datalist container. References/topics: HTML5 forms, < input list > , < datalist > , option elements, selectable typed input.
問題 #25
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.
答案：A
解題說明：
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.
問題 #26
The following output has more text than will fit in the element.
You need to apply CSS to contain the text inside the element ' s border without creating unneeded scrollbars or losing text. Which attribute setting should you use?
答案：D
解題說明：
The correct setting is overflow: auto;. The CSS overflow property controls how content behaves when it does not fit inside an element's padding box. The requirement has three parts: keep the text inside the element's border, avoid unnecessary scrollbars, and avoid losing text. overflow: hidden clips overflowing content and does not provide a user-visible scrollbar, so text can become inaccessible. overflow: visible allows excess content to render outside the element's box, failing the containment requirement. overflow: scroll makes the element scrollable, but user agents display scrollbars whether or not content is actually overflowing, which violates the requirement to avoid unneeded scrollbars. MDN describes overflow: auto as clipping overflow content at the padding box while allowing it to be scrolled into view, with scrollbars displayed only when content is actually overflowing. This makes auto the precise choice for a controlled text container. References

問題 #27
You define the Pet class as follows:
class Pet {
constructor(name, breed) {
this.name = name;
this.breed = breed;
this.show = function() {
var text = " < p > Your pet ' s name is " + name + " . The pet ' s breed is " + breed + " . < /p > " ; return text;
};
}
}
You need to derive a Dog class from the Pet class.
Complete the code by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct selection.
答案：
解題說明：
Explanation:
First blank: class Dog extends Pet {
Second blank: super(name, breed);
The correct syntax for deriving one JavaScript class from another is extends, so the derived class declaration must be class Dog extends Pet {. This creates Dog as a subclass of Pet, allowing Dog instances to inherit members defined by the Pet constructor, including name, breed, and the show() function assigned inside the parent constructor. Inside a derived class constructor, super() must be called before using this. The call super (name, breed); invokes the parent Pet constructor and passes the values required to initialize the inherited name and breed properties. Pet(name, breed); is incorrect because a class constructor cannot be invoked like a normal function. Pet.constructor(name, breed); is also incorrect because it does not call the parent constructor for the current instance. After super() runs, the Dog constructor can safely assign subclass-specific properties such as price and gender. References/topics: JavaScript classes, inheritance, extends, derived constructors, super(), custom class creation.
