Question

. Write a JavaScript function that counts the number of form elements and
displays them in an alert box
​

Answer 1

Answer:

If you have a div with child input elements in it (with a class of parent):

       parent = document.querySelector('.parent');

       function countChildren() {

           numberOfChildren = 0;

           children = Array.from(parent.children);

           children.forEach(child => {

               numberOfChildren += 1;

           })

           alert('Number of child elements: ' + numberOfChildren);

       }

Create a button with an onclick event of 'countChildren()'.

Hope this helps - have a great day!
