We've looked at how to access the current elements on the DOM, so now let's learn how to create and delete them.
To create an element, use the
createElement() method, which takes in an element type. We then store this reference into a variable, and use the methods we learned in the previous lessons to add attributes and text nodes.
var newElement = document.createElement("p"); body.appendChild(newElement); body.newElement.removeChild(newElement);
To set attributes to our newly created element Now we can just set the ID.
We may also create a text node by using the
createTextNode() method. Simply attach this node to our element.
var myTextNode = document.createTextNode("text here"); newElement.appendChild(myTextNode);
To append the element to the DOM, we use the
appendChild() method. This takes in the variable that holds a reference to your newly created element. You can then attach it to any pre-exiting element.
To remove a node, simply use the
var elementRemoval = document.getElementById("removeMe"); document.body.removeChild(elementRemoval);
