GetAttribute & SetAttribute Get and Set properties

GetAttribute Get Properties:

Syntax: Object.getattribute (attribute); This method does not belong to the Document object, so it cannot be called with the Document object, but only through the element node object; The setattribute is the same;

For example, var paras = document.getelementsbytagname (' P ');

Alert (Paras[0].getattribute (' title '))

SetAttribute modifying attributes;

Object.setattribute (Attribute,value);

Example: var shopping = document.getElementById (' purchases ');

Shopping.setattribute (' title ', "a list of goods");

Tips: attributes include title, Alt, class, ID and other categories, so you can use the above 2 methods to get and set the corresponding properties of the elements in the page, such as changing the style;
