1. A document is a tree of nodes2. Nodes are divided into different types: element nodes, text nodes, attribute nodes, etc.3. Each node is an object, and the atom of the DOM is an element node4.getElementById returns an object that corresponds to a specific element node in the document5.getELementsByTagName and Getelementsbyclassname return an array of objects that correspond to a specific set of ELEMENT nodes in the document, respectively.The 6.typeof operator can tell us whether its operand is
=document.getelementbyid (' id name '); Returns the element node, where each element node is an object, so the data type returned is an objectThe tag and class methods can iterate through a set of elements with a for loop4, gets and sets the element's attributes , which belong to the element node objectGets the property name of the attribute getattribute, a parameter that needs to be obtained.Set the property SetAttribute, two parameters, need to modify the property name, the modified value.Note
