- A. You have retrieved the query string "phone=%28802%29%20555-4781" and saved it in the variable phoneField. Which statement can you use to convert the string value of this variable to "phone=(802) 555-4781"? a. phoneField = phoneField.split(/&/g); b. phoneField = location.search(phoneField); c. phoneField = phoneField.replace(/\+/g, " "); d. phoneField = decodeURIComponent(phoneField); B. Suppose you need to save a string that contains spaces and punctuation marks to a cookie as a data value. If you have assigned the string to the variable tagLine, what statement should you include in your code before the one creating the cookie? a. document.cookie = "tag line=" + tagLine; b. let tagLine2 = setItem("tag line", tagLine); c. let tagLine2 = encodeURIComponent(tagLine); d. let tagLine2 = decodeURIComponent(tagLine);Complete the following JavaScript code in order to validate repeated students based on their ID within the “postStudent” function. Block Code: estControl.postStudent = (req,res)=>{ const {id, name,lastName} = req.body; if(!id || !name || !lastName){ res.status(400).send("Incomplete data {id, name, lastName}"); return; } const Student= { id, name, lastName } db.Students.push(Student); db.updateDB(); res.send('Student registered'); }This is a PHP code that generates a random number. It's supposed to check if my database already has that number generated. If it does, it generates another number. Else it stops. I am having difficulty figuring the errors out. <?php $CRN = rand(1000000, 9999999); $result = $pdo->query('SELECT * FROM class'); while($row = $result->fetch(PDO::FETCH_ASSOC)) { if($row["CRN"] == $CRN) { generate($pdo); } else echo $row["CRN"]; function generate($pdo) { $CRN = rand(1000000, 9999999); determine($pdo, $CRN); } function determine($pdo, $CRN) { $result = $pdo->query('SELECT *, count(CRN) FROM class WHERE CRN = '.$CRN); while($row = $result->fetch(PDO::FETCH_ASSOC)) {…
- Question 4 Write a function that will redact every third word in a sentence.
