we generally encounter a situation in domino web application to have a dblookup functionality
based on a field selection we need to populate subsequent fields ,
In this case if we use @DbColumn function, the form has to be refreshed,which reloads window which is not acceptable for most of the users
we can use XMLHttpRequest to perform a DBlookup from java script without reloading the current window
I have given two examples to show how simple it is to implement this feature
In Example 1 I have shown how to populate values from a different database
In Example 2 I have shown how to populate values based on a view in the current database.
