Ajax said novel is not novel technology , if you have used Google Map service will realize his advantages, of course, can not be used, hehe!
The following is a small example of their own writing, for reference only, laughed!

is to call the WHOIS query for 7e
Detailed content can go online search ~
The specific code is as follows:

main.html content

< HTML >
< Head >
< title > invoking WHOIS queries with Ajax </ title >
< Meta http-equiv = "Content-type" content = "text/html charset=gb2312" >
< META NAME = "keywords" CONTENT = "Call whois query with Ajax" >
< META NAME = "description" CONTENT = "Call whois query with Ajax" >
< META NAME = "Robots" CONTENT = "All" >
< META name = "AUTHOR" content = "Anlige" >
</ Head >
< Body >
< form name = "se" >
< input type = "text" name = "Domain" >
< input type = "button" value = "Query" onclick = "Star (se.domain.value)" >
</ form >
< Div ID =whois >
</ Div >
</ Script ></ span ></ TD >
</ Body >
</ HTML >
< Script language = "JavaScript" src = "Fun.js" ></ Script >
<!-- The following VBScript is decoded and is not used here for a while. -->
< Script language = "VBScript" > ...
Function STR2ASC (STRSTR)
STR2ASC = hex(ASC(STRSTR))
End Function
Function Asc2str (ASCASC)
Asc2str = chr(ASCASC)
End Function
