Hello all,
I borrowed a bit of JS code from a website and modified it so it could handle progressive dropdown box population for four boxes. It works, but I’d like to improve it. I have no talent to read JS code so I’m basically looking for ideas on how to do what I want to do. Let me show you the code as it is today:
<SCRIPT LANGUAGE=”JavaScript”>
var Sites = new Array();
var Divisions2 = new Array();
Sites[1] = “All Sites”;
Divisions2[1] = “All Divisions”;
[23 MORE PAIRS OF SITE/DIVISION FOLLOW]
var Departments2 = new Array();
var Divisions = new Array();
Departments2[1] = “All Departments”;
Divisions[1] = “All Divisions”;
[119 MORE PAIRS OF DIVISION/DEPARTMENT FOLLOW]
var Areas = new Array();
var Departments = new Array();
Areas[1] = “All Areas”;
Departments[1] = “All Departments”;
[444 MORE PAIRS OF DEPARTMENT/AREA FOLLOW]
function selectChange(control, controlToPopulate, ItemArray, GroupArray)
{
var myEle ;
var x ;
// Empty the second drop down box of any choices
for (var q=controlToPopulate.options.length;q>=0;q–)
controlToPopulate.options[q] = null;
if (control.name == “Division”) {
// Empty the third drop down box of any choices
for (var q=New_CorrAct.Department.options.length;q>=0;q–)
New_CorrAct.Department.options[q] = null;
}
if (control.name == “Department”) {
// Empty the fourth drop down box of any choices
for (var q=New_CorrAct.Area.options.length;q>=0;q–)
New_CorrAct.Area.options[q] = null;
}
// ADD Default Choice – in case there are no values
myEle = document.createElement(“option”) ;
myEle.value = “%” ;
myEle.text = “Select” ;
controlToPopulate.add(myEle) ;
// Now loop through the array of individual items
// Any containing the same child id are added to
// the second dropdown box
for ( x = 0 ; x < ItemArray.length ; x++ )
{
if ( GroupArray[x] == control.value )
{
myEle = document.createElement(“option”) ;
myEle.value = ItemArray[x] ;
myEle.text = ItemArray[x] ;
controlToPopulate.add(myEle) ;
}
}
}
// End –>
</script>
What’s happening is that we have the same division or department in several sites and the boxes don’t really narrow the selections because instead of one huge array, I have three separate ones. I’d like to be able to work things around so I can use one huge array so only what’s pertinent within a site/division/department shows up.
Can someone please guide me on how to do this? Help will be greatly appreciated in the form of cyber smiles ?
Thanks for reading!
