Below is the jQuery plug-in:Copy codeThe Code is as follows:; (function ($ ){

This. $ input = $ (this. o. input, this. e );
This. $ popup = $ (this. o. popup, this. e );
This. initEvent ();
},
Match: function (quickExpr, value, source ){
For (var I in source ){
If (value. length> 0 & quickExpr.exe c (source [I])! = Null)
This. $ popup. append ('<li> <a href = "javascript:;">' + source [I] + '</a> </li> ');

When an ajax request is called, it returns a json data. I used php to read the database for testing. If necessary, the Code is as follows:Copy codeThe Code is as follows: <? Php
Class DataFetch {
Private $ conn, $ rs;
Function _ construct (){
$ This-> conn = mysql_connect ("localhost", "root", "pwd") or die ("Cant't connect host ~ ");
Mysql_select_db ("studentinfo", $ this-> conn) or die ("Cant't select database ~ ");
}
Public function data_list ($ s ){
$ This-> rs = mysql_query ("select sno from student where sno like '$ s %'") or die ("Can't fetch ~ ");
$ DataList = array ();
While ($ row = mysql_fetch_array ($ this-> rs, MYSQL_ASSOC )){
Array_push ($ dataList, $ row );
}
Return $ dataList;
}
}
$ Search = isset ($ argv [1])? $ Argv [1]:
(Isset ($ _ GET ['search'])? $ _ GET ['search']: '');
$ Fetch = new DataFetch ();
$ Data = $ fetch-> data_list ($ search );
Echo '[';
Foreach ($ data as $ key => $ value ){
Echo "\ n \ t ";
Echo '"'. $ value ['sno']. '"';
If ($ key! = Count ($ data)-1) echo ','; else echo "\ n ";
}
Echo "] \ n ";
?>
