To
acheive this u need to do -
1. In the OnChange event of the combo1 call Java script
function inorder to populate the values to combo2 ...& Pass some params to
that method
2. Send-in the array of data to the client while loading the page
itself..
3. Submit the page to server in the onchange() event of combo2.(may
be selectIndexChnaged event)...
Refer these code blocks -
I. Calling
Point Combo1:
populateDependentCombo(Combo2,
arrayCombo2Values, this.value)
II. Actual
Function to populate values to Combo2: (General
implementation)
//Purpose: Populate dependent combo with data
array
function populateDependentCombo(cboDest, arrData,
strValue)
{
//Evaluate the
given object [string or combo] to combo
object
cboDestination =
eval("document.all['"+cboDest+"']");
if (cboDestination != null && arrData !=
null)
{
//delete all options of dest
combo
cboDestination.options.length=0;
//Populate
the destination combo with data retrieved from
dataArray
for(i=0;
i<arrData.length;
i++)
{
//If
data.base matches with strValue then add to the destination
combo
if
(arrData[i].base ==
strValue)
{
//Create
a new Option object and assign data to
it
cboDestination.options[cboDestination.options.length]
= new
Option(arrData[i].literal,arrData[i].id);
}
}
}
}
III Sending the
array to the client -
function data(base, id,
literal)
{
this.base = base; //Dependent Combo1
Value
this.id = id; //Combo2
Value
this.literal =
literal;//Combo2 Literal
}
Combo2Values = new
Array();
Combo2Values[Combo2Values.length]= new data(1,1,"with out any
body_s");
Combo2Values[Combo2Values.length]= new data(2,2,"ISO Std.
7.15_s");
