.... and what I need to do is pass to the calculateBidUnit
function the value of quantity, do a calculation on it and
plug into this field.
Which of course I know how to do for non-array values, but not
sure how to get the values to do the calculation on the JS
side if the fields are in an array.
Any help, as always, is greatly appreciated,

This question is probably more appropriate for a JS list... but I'm not =
mean, so I'll let you know. The easiest way would be to update the blur =
event qty input:
onblur=3D"calculateBidUnit(this.value);"
Now you have the value sent to that function. Another way would be to =
give your input and output an id each - let's say 'qty' and =
'bid_unit_value', respectively. Then reference those ids in your =
function. This gives you the following:
I'll give you a small warning. All browsers are not alike, so my =

compatibility portion of javascript (I use Mootools). Nonetheless, the =

with the more complicated stuff and you'll be smarter for it! =3DP
Hope that helps,

Hey Philip,
But will that ID value identify the right member of each
array? I thought about that but just assumed that it would not.

Each text input will only contain 1 value... and contain 1 unique "id." =
So, if you have multiple input boxes with the same name (qty[]), only =
the $_POST output will contain an array of each value. See below...
When you blur qty1, buv will receive the value 1; blur qty2, buv will be =
2; and so on. The last input box that you blur on will determine buv's =
final value (unless you throw in some logic to handle this)...
So, let's say you blur on qty2 and then submit the form, your PHP script =
will have this in $_POST...
If this is not what you're wanting, you will need to modify the behavior =
above. If you're wanting the bid_unit_value to contain all the values of =
each blur, you may want to do something like this...
Which may result from each blur in $_POST to be...
Or something along those lines. Then you can just explode() on that =
first index to get individual values. Maybe you can clarify your =
ultimate goal and we can assist you in what the best plan is.
Hope that helps,

What about using the DOM for getting to these elements and their
properties?

H'mm, in my experience the only surefire foolproof way to make sure you pic=
k the correct "bid_unit_value[]" input to match the corresponding "qty[]" i=
s to actually supply specific array indexes (so "qty[1]", "bid_unit_value[1=
]"; "qty[2]", "bid_unit_value[2]"; etc.). There are other Javascript approa=
ches that work in theory, but I've never been convinced of their robustness.
As to addressing these elements, I merely observe that in Javascript, by de=
finition a.z is *identical* to a["z"]. Application of this to the current s=
ituation is left as an exercise for the reader.
Cheers!
