Removing the "null" test from textfields

I need some idea in this regard.

The Scenario :

I have a page, where I have to display some fields, which are brought from database.

Before the records are fetched, the textfields show "null". I can get rid of this using script.

I want to know whether, we can make a generalized script, which could be used to check all the textfields, in a page and then, set a value of "", when it is null?

Is there a way to get all the textfields in a script?

I agree. Here's the link:
