Often browser displays information from database. Typical operation is viewing of some TREE: smaller part of tree is shown in browser, bigger part was not still inquired from database. Let's enter a special form (looks like tree), which would immediately send request to server, if user opens folder (and wants to see sub-folders). It would be very comfortable and economize time and torment (especially for un-experienced user). <tree name="A" action="script.cgi"> tree { src: root.gif } ti { src: folder.gif } When browser meet this html-element during loading document, it immediately sends "name=A&id=null", gets and displayes all folders of top level. After that, tree looks like so (code below is not really inside document!) <tree action="script.cgi"> <ti id=1> folder_name1 </ti> <ti id=2> folder_name2 </ti> <ti id=5> folder_name5 </ti> </tree> If user opens folder with "id=2", then browser immediately sends "name=A&id=2". After that, trees looks like so <tree action="script.cgi"> <ti id=1> folder_name1 </ti> <ti id=2> folder_name2 <ti id=3> folder_name3 </ti> <ti id=4> <any_html_element> </ti> </ti> <ti id=5> folder_name5 </ti> </ti> </tree> Server answers to browser by piece of html-text with TI-elements and any other html-elements, enclosed into TI. For example above: <ti id=2> <ti id=3> folder_name3 </ti> <ti id=4> <any_html_element> </ti> </ti>
