Menu
I am trying to connect 2 select boxes together.
What I have in mind is this: The user chooses a userid from the first select box. Once they select the userid it projects data based off only the userid.
There is a second select box that holds year values so that once a year is selected it will filter the data of that userid to only show for that specific year.
I’m not that well with Javascript so I don’t know what exactly I’m trying to do in the Javascript area.
[code=html]<script type=”text/javascript”>
function saveUser(userid)
{
var userid;
showUser(userid);
}
function saveYear(year)
{
var year;
showUser(year);
}
function showUser(userid,year)
{
if (userid ==”” && year ==””)
{
document.getElementById(“txtHint”).innerHTML=””;
return;
}
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject(“Microsoft.XMLHTTP”);
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById(“txtHint”).innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open(“GET”,”Status_23Gs.php?q=”+userid+”&year=”+year,true);
xmlhttp.send();
}
</script>
*******Select Box1
[code=php]
<?php
$query=”SELECT uuid,auth,emp FROM auto_atp.Admin”;
$result=mysql_query($query);
$options=””;
while($row = mysql_fetch_array($result)){
$id=$row[‘uuid’];
$users=$row[‘uuid’];
$options.=”<OPTION VALUE=”$id”>”.$users;
}
?>
<b>UUID:</b><select id=”theuser” name=”users” onchange=”saveUser(this.value)”>
<OPTION VALUE=0><b>UID</b>
<?=$options?>
</SELECT>
[code=php]
*****Select Box 2*******
<?php
$query=”SELECT serial,year FROM auto_atp.GeoProbe GROUP BY year ORDER BY year”;
$result=mysql_query($query);
$options=””;
while($row = mysql_fetch_array($result)){
$RES=$row[‘year’];
$options.=”<OPTION VALUE=”$RES”>”.$RES;
}
?>
<select id=”theyear” name=”year” onchange=”saveYear(this.value)”>
<OPTION VALUE=0>
<?=$options?>
</SELECT>
