NEW QUESTION # 32
Which three methods are associated with the HTML5 localStorage API? Choose 3.
Answer: A,D,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.

NEW QUESTION # 33
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?
Answer: A
Explanation:
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

NEW QUESTION # 34
You need to contain overflowing text inside the element ' s border without creating unneeded scrollbars or losing text. Which attribute setting should you use?
Answer: B
Explanation:
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.
NEW QUESTION # 35
You need to call a function named process when a user clicks a button.
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:
< button onclick= " process() " > Process < /button >
< script >
function process()
{
}
< /script >
The button must use the onclick attribute because the required action occurs when the user clicks the button.
The plain word click is an event name used in JavaScript event listeners, but it is not the correct inline HTML event-handler attribute. The value of the onclick attribute must be process() because the function must actually be invoked when the click event occurs. Using process alone only references the function name and does not call it in this inline markup context. this.process would attempt to reference a property on the current element, and javascript:process is not the correct handler expression. Inside the < script > block, the correct function declaration is function process(). This defines the named function that the button's onclick attribute calls. The final structure therefore connects the button event directly to the script function: when the user clicks Process, the browser runs process().
NEW QUESTION # 36
Which JavaScript method is used to draw a circle on a canvas?
Answer: D
Explanation:
The correct method is arc(). In the Canvas 2D API, circles and circular arcs are drawn by creating an arc path on the canvas rendering context. MDN defines CanvasRenderingContext2D.arc() as creating a circular arc centered at (x, y) with a specified radius, start angle, end angle, and drawing direction. To draw a full circle, the common pattern is to call beginPath(), then arc(x, y, radius, 0, 2 * Math.PI), and then use stroke() or fill() to render the path. There is no standard Canvas 2D method named circle(), so option A is invalid. ellipse() can draw ellipses and can mathematically draw a circle if both radii are equal, but the classic and exam-targeted method for drawing a circle is arc(). bezierCurveTo() draws cubic Bezier curves and is used for custom curved paths, not the direct circle primitive. References/topics: Canvas 2D context, arc() method, drawing circles, radians, path rendering.
