NEW QUESTION # 39
Given the JavaScript below:
01 function filterDOM(searchString){
02 const parsedSearchString = searchString & & searchString.toLowerCase();
03 document.querySelectorAll( ' .account ' ).forEach(account = > {
04 const accountName = account.innerHTML.toLowerCase();
05 account.style.display = accountName.includes(parsedSearchString) ? /* Insert code here */;
06 });
07 }
Which code should replace the placeholder comment on line 05 to hide accounts that do not match the search string?
Answer: B
Explanation:
We have a ternary:
account.style.display = accountName.includes(parsedSearchString)
? /* if true */
/* if false */;
Requirement:
* If the account matches the search string # show it.
* If it does not match # hide it.
For display:
* Show: ' block ' (or similar visible value).
* Hide: ' none ' .
So we want:
account.style.display = accountName.includes(parsedSearchString)
? ' block '
' none ' ;
That corresponds to option A.
Why others are wrong:
* B, C use values suitable for visibility, not display.
* D ( ' none ' : ' block ' ) inverts the logic, hiding matches and showing non-matches.
