jQuery to populate array-named form fields based on first entered value where number of fields is un
- by da5id
Greetings,
I have a form with a variable number of inputs, a simplified version of which looks like this:
<form>
<label for="same">all the same as first?</label>
<input id="same" name="same" type="checkbox" />
<input type="text" id="foo[1]" name="foo[1]" value="" />
<input type="text" id="foo[2]" name="foo[2]" value="" />
<input type="text" id="foo[3]" name="foo[3]" value="" />
<input type="text" id="foo[4]" name="foo[4]" value="" />
<input type="text" id="foo[5]" name="foo[5]" value="" />
</form>
The idea is to tick the #same checkbox and have jQuery copy the value from #foo[1] into #foo[2], #foo[3], etc. They also need to clear if #same is unchecked.
There can be any number of #foo inputs, based upon input from a previous stage of the form, and this bit is giving me trouble. I'm sure I'm missing something obvious, but I can't get any variation on $('#dest').val($('#source').val()); to work.
Help!
