質問 # 18
Which markup segment creates an SVG ellipse?
正解：D
解説：
The correct answer is D because an SVG ellipse is created with the < ellipse > element and the required geometry attributes cx, cy, rx, and ry. The cx attribute defines the x-coordinate of the ellipse's center point, and cy defines the y-coordinate of the center point. The rx attribute defines the horizontal radius, while ry defines the vertical radius. In option D, cx= " 200 " and cy= " 80 " correctly position the center of the ellipse, while rx= " 100 " and ry= " 50 " correctly define an ellipse that is wider than it is tall. Option A is invalid because the element name is misspelled as < ellipsp > , so the browser will not interpret it as an SVG ellipse.
Option B incorrectly uses x and y attributes instead of the ellipse-specific center and radius attributes. Option C correctly uses cx and cy, but incorrectly uses x and y where rx and ry are required. References/topics: SVG markup, < svg > container, < ellipse > element, center coordinates, horizontal radius, vertical radius.
質問 # 19
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?
正解：A
解説：
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.

質問 # 20
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.
正解：
解説：
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.
質問 # 21
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?
正解：B
解説：
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.
