php二级联动菜单代码示例:
script language = javascript> var onecount; onecount=0; subcat = new array(); ?php mysql_connect(localhost,charles,
charles); mysql_select_db( _crm ); $sql = select * from site; $result = mysql_query( $sql ); $count = 0; while($res = mysql_fetch_row($result)){ ?> subcat[ ?php echo $count ?>] = new array
( ?php echo $res[0]?>, ?php echo
$res[2]?>, ?php echo $res[1]?>); ?php $count++; } echo onecount=$count;; ?> //联动函数 function changelocation(locationid) { document.myform.ctype.length = 0; var locationidlocationid=locationid; var i; for (i=0;i onecount; i++) { if (subcat[i][2] == locationid) { //var newnewoption1=new option(subcat[i]
[1], subcat[i][0]); //document.all.ctype.add(newoption1); document.myform.ctype.options[document.
myform.ctype.length] = new option(subcat
[i][1], subcat[i][0]); } } } /script> form method=post name=myform
action=ru_query.php> select name=type onchange=changelocation(
document.myform.type.options[document.myfo
rm.type.selectedindex].value) size=1> option selected value=>main /option> ?php $sql = select * from entreprise; $result = mysql_query( $sql ); while($res = mysql_fetch_row($result)){ ?> option value=> ?php echo $res[1]; ?> /option> ?php } ?> /select> select name=ctype> option selected value=>sub /option> /select> input type=submit name=submit value=search> /form> 以上代码就是php二级联动菜单的具体实现方法。
