I need more elegant solution.

From MS KB under dynamic properties chapter:

Handling events can get fairly involved and inefficient. Implementing event handlers on a document that is not fully known at design time (database driven Web pages or pages with data binding, for example) is only possible with event bubbling . As a result, authors frequently implement a single global handler at the top of the event chain to update everything. On the other hand, with dynamic properties, authors can automatically determine a minimal and optimal recalculation of properties and evaluate only the expressions that really need to be evaluated.

... also

This frees authors from the requirement of learning script programming before they can design advanced features for their pages.

I can force using Internet explorer. I read about setExpresson() method in
MSKB, run its samples and found that using setExpresson() is more
elegant implementation of this: no need to write separate javascript
functions!

There is also a sample in MSKB about setting dynamic style properties like

< INPUT TYPE=text
STYLE="width:expression(eval(oBox1.value)+eval(oBox2.value))" >

Unfortunately, value property does not belong to style.

However, description of < input type=text> element VALUE attribute
says that

Expressions can be used in place of the preceding value(s), as of Microsoft® Internet Explorer 5. For more information, see Dynamic Properties.

I read July MSKB "Dynamic properties chapter" but does'nt found referred "more information"!
