Basic usage: prototype. JS divides every major class into a class, which is easy to use. to produce a specific effect, you only need to use new class. function (<argument>. for example:

 
<Div id = "div1"> <a href = "#" onclick = "new element. Toggle ('div2')"> click me </a> </div>
<Div id = "div2"> hello! </Div>
 

When you click "Click me", div2 will be hidden or displayed alternately. note that you can add infinite parameter to toggle, such as element. toggle (''div2'', ''div3 '', ''div4 '',...)
