Simple JavaScript framework for manipulating HTML elements that are compatible with all browsers

1. Take element $id based on ID name (idname)
2. The element $class (ClassName) based on the class definition returns all the array of elements defined as className in the class, or $eclass (ClassName) returns the first element
3. Take element $tag according to tag name (TagName) returns an array of all elements whose label name is TagName, or $etag (TagName) returns the first element
4. A parent-child relationship takes an element $dom (id#idname class#classname tag#tagname) returns an array of elements whose label name is className for all elements under the Idname element with the class TagName, or $ Edom (id#idname class#classname tag#tagname) returns the first element, separated by a space between each relationship, and the corresponding relationship is delimited by a well number, and the relationship can be arbitrarily ordered
5. The extracted elements will be accompanied by an extension method
A.getattr (attrname) take attribute
B.setattr (Attrname, attrValue) setting properties
C.getstyle (stylename) Take style
D.setstyle (stylename,stylevalue) Setting style
E.getval () value, if it is the value of Input,select,textarea, the other tags are taken out of the embedded HTML
F.setval (value) setting value, if the value of Input,select,textarea is set, the other label is set to the embedded HTML
G.show () display element
H.hide () Hidden elements
5.AJAX operation using Functions, Ajax (Type,url,callback,data);
A.type Submission Type
B.url Submit Address
C.callback callback function
D.data pending Data (a=1&b=2)
6.Cookie operation using function, Cookie.set (k,v,e) k name v value e valid (seconds) cookie.get (k)
