I have a variable number of lines, with each line being a transaction,
displayed in my jsp. Each line has an amount value with the name
equal to the line it is displayed on. For example name=amount0 on
line 1
name=amount1 on line 2, etc...
I am attempting to edit the values in the amount field prior to
submitting the form. I have a for loop that goes through the lines
but haven't been able to come up with a way to dynamically address the
field. In the example below I was hoping that 'i' would append itself
to the field name 'tranLimit'. Unfortunatly, it doesn't. How would I
make the field name variable?
isMoney = /^\d+\.\d{2}$/;
// See list of all accounts available to user
function submit_form() {
continueSubmit = "Y";
rowCount = document.chglim its.rowCount.va lue;
for(i=0;i<rowCo unt;i++) {
if(!isMoney.tes t(document.chgl imits."tranLimi t"i.value)) {
alert('Invalid Dollar Amount');
continueSubmit = "N";
} else {
}
}
if(continueSubm it == "Y") {
document.chglim its.cmd.value = 'chg_tranlimit' ;
document.forms['chglimits'].submit();
}
} 3 1427

If you used the collection syntax for accessing forms and their controls,
you can build up names with the concatenation operator. Your attempt would
be written:
document.forms['chglimits'].elements['tranLimit' + i].value

So close...
But close only counts with grenades and horseshoes.
for(i=0;i<rowCo unt;i++) { if(!isMoney.tes t(document.chgl imits."tranLimi t"i.value))
Now come on - you can't just stick a variable name after quotes in JSPs,
either. :)
document.chglim its.elements["tranLimit" +i].value
Note: the above is not good cross-browser syntax.
If supporting non-IE browsers, use
document.forms["chglimits"].elements["tranLimit" +i].value

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
