Hey guys i am learning JS, the thing is i made a simple application which display the multiplication table of the input number. The problem is that when i enter a number again the it will print below the previous multiplication table so i want to delete all the child element of div tag when i enter a number again
function print() { var box = document.getElementById("table"); for(let i=1 ; i<=10 ; i++) { var t = document.getElementById("tabInput").value; var t_Element = document.createElement("p"); var t_line = document.createTextNode(t + " x " + i + " = " + t*i); t_Element.appendChild(t_line); box.appendChild(t_Element); } }

If you need to clear ALL elements, then there is no need to iterate through them.
You can just clear the innerHTML
of the div
like so:
document.getElementById('yourdivid').innerHTML = '';
And then you can proceed with the rest of your code that creates the new elements
