1) AFAIK, Javascript will blithely convert text entered into a text
field into a numeric without any prompting, given the proper context.
Example: the user enters '7' in a text field and Javascript will
interpret it as 7.
2) Using the onChange event? Maybe. Though it's pretty straightforward--
<input name="myfield" type="text" size="5" onChange="some_javascript">
The javascript is contained earlier in the file, between a matched pair
of <script>/</script> tags.
Here's the original post:
I'd like to have a form where the user enters a number, generates an
onChange() event, and the form beneath creates a set of text input
blanks corresponding to the number the user entered. All dynamically,
not generated by pushing a button first. I've been checking my texts and
googling, and I must be missing something.
Further explained:
Originally, the form has some fields on it, one of which is a field
asking for a number. When the user enters a number in that field and
then moves off of it (generating an onChange event), a space opens up
somewhere else on the form with a number of text fields. If the user
enters the number '3' in the blank, the onChange()/Javascript/etc.
creates 3 text fields named, for example, 'field_1', 'field_2' and
'field_3'.
Some hints:
If you onChange() javascript generates calls to document.write(), it
will force a new form to appear, not the modified original form. This is
due to the way intrinsic event handlers work. So that way won't work.
Apparently part of the solution to this may lie in having a span or
other tag with an id that is known to the javascript, which it then can
modify by creating the new fields within it.
Honestly, I didn't think the original post was that vague, nor did I
think this was non-trivial (for someone very familiar with DOM,
Javascript, and maybe AJAX). I just don't happen to be fully familiar
with all that stuff
