二级联动菜单
二级联动下拉菜单 自家用的 js二级联动菜单 其实我觉得 asp二级联动菜单 与 php二级联动菜单 两个相同只是表示方式不一样.
<script>
function GetObjId(ObjName)
{
//alert(document.all.tags('select')[i].name);
for(i = 0; i < document.all.tags('select').length; i++)
{
if (document.all.tags('select')[i].name == ObjName) {return(i); break;}
}
return(-1);
}
function Do_ToDo_Change(ObjName1, ObjName2, StatInt)
{
//document.forms[0].elements[0].name
var id1, id2, tempstr, tempint
var my_array = new Array();
<?php
$list='';
for($i=1;$i<=11;$i++){
$osql ="Select * from tanbme where f_id=$i";
$resul =mysql_query($osql) or die(mysql_error());
while($res =mysql_fetch_array($resul)){
$list=$list.$res['id'].'|'.$res['z_name'].',';
}
?>
my_array[<?php echo $i-1; ?>] = '<?php echo $list;?>';
<?php
$list='';
}
?>
id1 = GetObjId(ObjName1);
id2 = GetObjId(ObjName2);
tempint = document.all.tags('select')[id2].length;
for(i = 1; i < tempint; i++) {document.all.tags('select')[id2].options[1] = null}
if (document.all.tags('select')[id1].selectedIndex > StatInt - 1)
{
tempstr = my_array[document.all.tags('select')[id1].selectedIndex - 1].split(",");
for(i = 1; i <= tempstr.length; i++) {document.all.tags('select')[id2].options[i] = new Option(tempstr[i - 1].substr(tempstr[i - 1].indexOf("|") + 1), tempstr[i - 1].substr(0,tempstr[i - 1].indexOf("|")))}
}
}
</script>
