Positioning the cursor in an input field

[Jay Damon]

Is there a way to obtain the position of the cursor in an input field? Conversely, is there a way precisely position the cursor in an input field?

I am writing a mask function for an input field and it occurred to me that the user may want to use the arrow keys to go back and insert a missing character in the input field.

It is easy enough to trap arrow keys and allow the user to insert a new character but when he does and the input field value is reformatted, the cursor goes to the end of the field, i.e. after the last character.

What I would like to do is put the cursor back to its previous position so that the user may enter multiple characters at the insert point.

Any suggestions would be appreciated.

You can not control the position of the cursor in a text field

In IE, there is a TextRange object, that you can use. Not sure, if there something like tatn in Gecko.
