Document.createelement (tagName) : The CreateElement method on a Document object can create an element that is specified by tagname, and if a string div is used as a method parameter, a DIV element is generated;
document.createTextNode (text) : The createTextNode method of the Document object creates a node that contains static text;
<element>.appendchild (Childnode) : The AppendChild method adds the specified node to the list of child nodes of the current element (as a new child node). For example, you can add an option element as a child of a SELECT element;
<element>.getattriture (name): These methods get and set the value of the Name property in the element;
<element >.setattritube (Name,value): Each of these methods gets and sets the value of the Name property in the element;
<element>.insertbefore (Newnode,targetnode) : This method inserts the node newnode as a child of the current element in front of the targetnode element;
<element>.removeattribute (name): This method deletes the property name from the element;
< Element>.removechild (Childnode): This method deletes the child element Childnode from the element;
<element>.replacechild (Newnode,oldnode) : This method replaces the node OldNode with the node NewNode
<element>.haschildnodes (): This method returns a Boolean value that specifies whether the element has child elements;
