With this code you can set all fields "readOnly":
for (var nPageCount = 0; nPageCount < xfa.host.numPages; nPageCount++)
{
var oFields = xfa.layout.pageContent(nPageCount, "field");
var nNodesLength = oFields.length;
// Set the field property.
for (var nNodeCount = 0; nNodeCount < nNodesLength; nNodeCount++)
{
oFields.item(nNodeCount).access = "readOnly";
}
}
Use it in the mouseDown-event of your send-button.
