Developing Web Applications with ColdFusion
<!--- Dump the recordset --->
q.dump(true);
</SCRIPT>

Transferring Data From Browser to Server
This example serializes form field data, posts it to the server, deserializes it, and
outputs the data. For simplicity, only a small amount of data is collected. In
applications where complex JavaScript data collections are generated, this basic
approach can be extended very effectively.
<!--- Get WDDX JS utility objects --->
<SCRIPT LANGUAGE="JavaScript"
SRC="/CFIDE/scripts/wddx.js"></SCRIPT>
<!--- Add data binding code --->
<SCRIPT>
// Generic serialization to a form field
function serializeData(data, formField)
{
wddxSerializer = new WddxSerializer();
wddxPacket = wddxSerializer.serialize(data);
if (wddxPacket != null)
{
formField.value = wddxPacket;
}
else
{
alert("Couldn’t serialize data");
}
}
// Person info recordset with columns firstName and lastName
var personInfo = new WddxRecordset(new Array("firstName",
"lastName"));
// Add next record to end of personInfo recordset
function doNext()
{
nRows = personInfo.getRowCount();
personInfo.firstName[nRows] =
document.personForm.firstName.value;
personInfo.lastName[nRows] = document.personForm.lastName.value;
document.personForm.firstName.value = "";
document.personForm.lastName.value = "";
}
