How to get Objects:
window.document.getElementById (' Miao ');//window can be omitted
document.getElementById (' Miao ');//id is unique, not conflicting, so gets an object value, not an array
document.getElementsByTagName ("a");//tag name is not unique get all a tag object, generate array
Document.getelementsbyclassname ("a");//classname is not unique, gets all the classname for a label object to generate an array
Document.getelementsbyname ("a");//name property is not unique, gets all label objects with Name A, generates an array
is the entire label .

after you get the object, you can call the object's innerHTML property if you want to get the contents of the tag
The label object. InnerHTML: Represents the text between tags
The Label object. InnerHTML = new data: The assignment of content between tags

confirm (): pops up a popup with confirmation and cancellation
