Can any one help me with a line of javascript to be executed when a WO
PopUpButton is changed?
I am familiar with adding an extra binding to a popUpButton of the
form:
onChange = "form.submit();"
In this case I want to do something different. My application is
recording payments on several currencies. I have a popUpButton to
select a currency from a small array. The next TextField displays the
exchange rate. Selecting a currency *copies* an exchange rate from the
currency table into the payment's exchange rate field. The individual
payment's exchange rate can then be edited if required. The idea being
that the currency table is not going to be continually adjusted and
will therefore only be approximately right. Selecting a currency will
insert that last known exchange rate from the currency table but the
operator is free to adjust that figure for a specific item. If the
operator uses the popUp to select a different currency the rate should
again be set to to a value from the currency table.
I need to set up the popUp Button so that it transfers its exchange
rate value to the payment record only when the popUp is changed. If
the user edits the exchange rate directly, without touching to the
popUpButton I want the user's textfield entry to take precedence and
not be overridden by the popUp.
I think I can do this by binding a single line of javascript to the
popUp. something like
onchange = "form.rate.value = value"
where the last "value" is the attribute bound to the value binding of
the popUp.
I know this is isn't quite right. Can someone help me with the next
step?
Here's what I have:
Form1: WoForm {}
PopUpBotton1 : WOPopUpButton {
list = currencyArray;
item = currencyItem;
displayString = currencyItem.abbreviation;
selection = payment.currency;
value = currencyItem. fxRate;
onChange = "form.rate.value = value"; <-- this line is not correct
}
TextField1: WOTextField {
value = payment.fxRate;
name = "rate";
}
