How can I get the field type at a position (x,y) ?

Colin Fraser, sharon,

I suspect what you are asking is essentially impossible, if not just 
highly unlikely. In a client-side script how can you establish what is 
where? Obviously, by using an event, like the onMouseMove, to determine 
the current position of the pointer. The problem then becomes how can 
you induce the user to move the pointer to the required position. 
Secondly, you will probably need to replicate your definition script for 
every resolution there is. The position of a field on a form should not 
vary according to the user's resolution, but you cannot guarrantee 
this. 
I suspect you are asking too much from JavaScript, however, if you were 
to use Java, you could probably avoid trying to find the x,y position 
alltogether. 
The real problem with this question is its vagueness though. Are you 
sure you are asking the right question? Is it possible you might be 
looking for the tab-order of a set of form fields? 
The part of the question that reads "field type" is odd though. Are you 
referring to the data type to be returned? String, integer, real, 
double, single or what? I suggest you read the JavaScript User's guide, 
a link to it can be found in the main page of JavaScript FAQTS, for this 
answer.
