JQuery gets objects from the class, which is very convenient. Not much to mention below

[Javascript]
/*
* ClsName: Specifies the class name.
* TagName: The given HTML element. If any tagName is '*'
* ClassElements: Return Value
*/
Function getElementsByClassName (clsName, tagName ){
Var ClassElements = [];
SelElements = document. getElementsByTagName (tagName );
 
For (var I = 0; I <selElements. length; I ++ ){
If (selElements [I]. className = clsName ){
ClassElements [ClassElements. length] = selElements [I];
}
}
Return ClassElements;
}
