56. Frage
Which value does the following JavaScript code fragment store in the variable num?
var num = localStorage.length;
Antwort: C
Begründung:
The value stored in num is the number of key-value pairs currently stored in localStorage. The localStorage object implements the Web Storage Storage interface, which stores data as named string key/value entries for the current origin. Its length property is read-only and returns the number of data items stored in that Storage object, not the size of the stored data and not the remaining capacity. MDN's Storage reference explicitly defines length as returning the number of data items stored, and its example shows that after three items are added to localStorage, localStorage.length returns 3. Therefore, if the storage area contains five named entries, num receives 5; if it contains no entries, num receives 0. Option A is incorrect because available bytes are not exposed through length. Option B is unrelated to Web Storage. Option C is incorrect because browser storage quota or capacity is separate from the length property. References/topics: Web Storage API, localStorage, Storage.length, key-value storage, application state.
57. Frage
You want to display a message box showing the user ' s current latitude and longitude as identified by the user' s browser.
Complete the code by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct selection.
Antwort:
Begründung:
Explanation:
First drop-down: navigator.geolocation
Second drop-down: navigator.geolocation
Third drop-down: getCurrentPosition(showLocation)
The correct API object is navigator.geolocation because browser-based geographic location is exposed through the Geolocation API, not through window.location. window.location represents the current page URL and navigation state; it does not provide latitude or longitude. The first selection checks whether the browser supports geolocation by evaluating navigator.geolocation. Inside the block, the same object must be used to request the user's current position. The correct method is getCurrentPosition(showLocation), which requests the device's current location and passes a position object to the callback function when the location is available. The callback then reads position.coords.latitude and position.coords.longitude and displays those values with alert(). The alternatives that pass window.location are incorrect because they provide page- location information rather than geographic coordinates. The alternatives that call showLocation(...) directly are also incorrect because the browser must first retrieve the actual position object. References/topics:
Geolocation API, navigator.geolocation, getCurrentPosition(), callback functions, latitude and longitude.
58. Frage
Which CSS property defines the sides of an element where other floating elements are not allowed?
Antwort: C
Begründung:
The correct property is clear. In CSS layout, float removes an element from the normal inline flow and positions it to the left or right, allowing following content to wrap beside it. The clear property controls whether an element may be positioned next to preceding floated elements or must be moved below them.
MDN defines clear as the property that sets whether an element must be moved below floating elements that precede it. Typical values include left, right, both, and none, allowing the developer to block floats on one or both sides. display controls the formatting behavior of an element, such as block, inline, flex, or grid. float creates the floating behavior; it does not prevent other floats from appearing beside an element. position controls positioning schemes such as static, relative, absolute, fixed, or sticky. Therefore, only clear directly defines the sides where adjacent floating elements are not permitted. References/topics: CSS floats, content flow, clearing floated elements, layout positioning.
59. Frage
Review the grid container requirements and mockup on the left. Which markup should you use to define the grid container?
Antwort: B
60. Frage
You want to position a specific element so that it always directly follows the previous element, which is positioned by default, regardless of the viewport characteristics. Which positioning method should you use?
Antwort: D
Begründung:
The correct positioning method is static. In CSS, position: static is the default positioning behavior for elements. A statically positioned element remains in the normal document flow, meaning it is laid out according to the order of the markup and directly follows preceding elements unless another layout rule changes that flow. MDN defines static positioning as placing the element according to the normal flow of the document, with top, right, bottom, left, and z-index having no effect. This matches the requirement that the element always directly follows the previous default-positioned element and does not depend on viewport characteristics. absolute removes the element from normal flow and positions it relative to a containing block.
fixed also removes it from normal flow and positions it relative to the viewport. sticky starts in normal flow but changes behavior relative to a scrolling ancestor when a threshold is crossed. References/topics: CSS positioning, normal document flow, static positioning, viewport-independent layout.
