OT: javascript question ... can it be done

Assume: var x = "one_two_three_four";
Is there any way to do the following with only one line of
code?
var tmp = x.split('_'); // tmp =
array("one","two","three","four")
y = x[x.length-1]; // y = "four"

Look into lastIndexOf() and slice()

Raid question, can it be done or not

hi, and thanks in advance for any help given regarding my question.
i have two raptors set up as a mirrored raid array, my question is can i go into bios and change them to a stripped array (raid 0) for peformance without having to reinstall xp and if so what are the best settins?

I can confirm supershanks answer, as i've TRIED it.. and no, if you change ANY of the nVraid settings, you have to reinstall windows..
I don't think this is the case with all RAID controllers though, as the promise controller on my other board, was more flexible..
you could just make a ghost image of your current setup, then change the settings, and ghost it back. check my sig for instructions using ghost with nvraid

Reports Question -- Can this be done?

Encrypting a report for distribution in an e-mail

Hello Everyone!
Does anyone know how to encrypt a report? This will be batch
processing of emailing reports using Reports Server.
Thanks in advance,

Vannette,
You can send reports over the internet via ssl, but Reports

Is there a way that you can have two different text fields (email, phone) that one at least one of them must be completed before submitting the form? Can it be done using javascript in the validation tab? if so, how?

Is there a way that you can have two different text fields (email, phone) that one at least one of them must be completed before submitting the form? Can it be done using javascript in the validation tab? if so, how?

Here is one solution:
// mouse up action for submit button;
function GetField(cName) {
// get field object for cName field with error checking;
var oField = this.getField(cName);
if(oField == null) app.alert("Error accessing field named " + cName + "\nPleae verigy field name, spelling and capitalizeation.", 1, 0);
return oField;
} // end GetField function;
var oPhone = GetField("phone");
oPhone.required = oPhone.value == oPhone.defaultValue;
var oEmail = GetField("email");
oEmail.required = oEmail.value == oEmail.defaultValue;
if(oPhone.required && oEmail.required) {
app.alert("Missing required fields.", 1, 0);
} else {
app.alert("Submitting form", 3, 0);

JAVASCRIPT: Accessing the sessionbean - how ??? can it be done?

Hi,
I need to access the sessionBean from javawscript. I have trawled throughj all posts and have got no satisfactory code.
Can this be done?
I have tried for eg alert(#{sessionBean.firstName}) and get a syntax error, i assume due to # symbol. do i need to CDATA this request?
Any help, much appreciated.
Regards,
LOTI

Your problem is trying to access server side information from the client side, so that alert is never gonna work in that simple form. If you want javascript access to a sessionbean variable, that variable will have to be present in the final rendered page....meaning bring it into your page as either a visible or inviisble field and then using javascript to read that. Thats one solution?

You need to ask Apple to reset your security questions; ways of contacting them include clicking here and picking a method for your country, phoning AppleCare and asking for the Account Security team, and filling out and submitting this form.
They wouldn't be security questions if they could be bypassed without Apple verifying your identity.

Need to keep record for each response to each question on quiz. Can this be done outside an LMS?

For auditing purposes, I need to keep a record of the user's response to each question of a 35 question quiz.
I don't think my LMS (Halogen) has this capability. Is there a way to keep a record of each slide, outside of screen capturing each response?

JavaScript Error : Can't move focus to the control because it is invisible,

I have one JSP page in my project where i am putting all input to save personal details of a person.
This personal details header contains button(to collapse or expand).
I input all details and save. It works fine but when i collapse the header and name, age etc are not visible.
Only Save and cancel button is visible. so i click on save and following javascript error show up :
Can't move focus to the control because it is invisible, not enabled, or of a type that does not accept the focus.
In case of expand mode,If there is any error while providing input in text boxes , i have given pop up to display that like " Name field is mandatory " and control focus to that field again. it works fine.
In case of collapse, as fields are not visible and if i directly click on save button. Pop up is displayed as usual "Name field is mandatory" but it pop up again javascript error
"Can't move focus to the control because it is invisible, not enabled, or of a type that does not accept the focus."
Please let me know how to reolve this?

1) there is a JSP forum
2) that still doesn't make it a forum to ask javascript questions
Please let me know how to reolve this?Who says that you can resolve it? If it isn't allowed, don't try it. Likely you'll have to rethink the design of your page.

Additional Pageflow - JavaScript Questions

I was hoping someone (bea employee???) could answer a couple more JavaScript questions
for me?? First one is how do I (can I) do something similar to what John Rohrlich
(see below) suggested inside a netui-data:grid tag? Among other things that didn't
workI tried this:
<netui-data:anchorColumn action="deleteUsr" title="">
<netui:anchor action="deleteUsr" onClick="return confirmDelete('user', {container.item.usr_nm}
); return false;">
Drop
<netui:parameter name="userToDrop" value="{container.item.usr_nm}" />
</netui:anchor>
</netui-data:anchorColumn>
From this snippet you might be able to guess what my next question is. Is there
a way to render a variable inside the onClick value? I have tried a number of
things to no avail, stuff like:
<netui-data:getData resultId="thisId" value="{container.item.userId}" />
<netui:anchor action="dropUser" onClick="return confirmDelete('user', '<%=(String)pageContext.getAttribute("thisId");%>');
return false;">
BTW this is in a repeater I have else ware in my code. I would really like to
convert everything to grids to get the sorting, filtering and paging capabilities.
I would like to be able to pass the parameter to my JavaScript so the user has
a little more info on what he is dropping - here is the script:
function confirmDelete(){
//arg 1 would be the record type i.e. "user"
//arg 2 would be the key identifier i.e. "Fred"
var question = "Are you sure you want to drop this record?";
var argNum = confirmDelete.arguments.length;
if (argNum == 1){
question = "Are you sure you want to drop this "+confirmDelete.arguments[0]+"?";
else if (argNum == 2){
question = "Are you sure you want to drop the "+confirmDelete.arguments[0]+"
"+confirmDelete.arguments[1]+"?";
return confirm(question);
Thanks,

John,
If you want to put up a confirm dialog before calling an action from
an
anchor it is done as follows.
Here is an example from code of mine that deletes a customer order, if
the
user confirms the delete. I pass the order id as a parameter.
- john
Here is the JavaScript -
function confirmDelete() {
if(confirm('Continue with order delete?'))
return true;
else
return false;
Here is a sample anchor tag -
<netui:anchor action="requestToDeleteOrder" onClick="return
confirmDelete(); return false;">
Delete
<netui:parameter name="orderId" value="{container.item.orderId}"/>
</netui:anchor>

Thanks Eddie, I looked at that reply when you gave it but it didn't give me enough
to go on. You suggested:
<netui-data:expressionColumn title="Show Alert" value="<a href='javascript:alert(12345);return
false;> {container.item.customername}</a>" />
I started a new thread after that one - What is the best way to call a pageflow
action from JavaScript? Guess I was sort of beating around the bush on this. Can
you see where I was going? If I use the method you describe above how do I call
my dropUser pageflow action if the user confirms the drop in the java dialog?
Thanks, John

John--
You might check an earlier response about this from a different thread.
"Re: Confirmation dialog w/netui:anchor and netui-data:anchorColumn"
on
1/28/2004.
It's possible to do though not intentional; the 8.1 grid wasn't
really designed to do this.
The NetUI team is certainly aware of the limitations with using this
version of the grid and is working to address said limitations with a
much improved tag set in v9. If you have additional feedback on
features you'd like to see, please feel free to send them along --
including your top 10 (or whatever!) reasons not to use the grid. :)
In the meantime, depending on what you need to do, the repeater may
suit your needs well, though you may need to do some work to implement
sort / filter logic.
Hope that helps.

The grid doesn't support event handlers like onClick but I have included

handler when using the repeater. Let me know if you have any questions

the code.
Most of the code is standard repeater code. The interesting code is

TS3988 I changed my Apple ID to my new email address successfully for the iTunes and App store but it won't work for iCloud and it won't recognize my password. I read that this can't be done. How am I supposed to get into iCloud?

I changed my Apple ID to my new email address successfully for the iTunes and App store but it won't work for iCloud and it won't recognize my password. I read that this can't be done. How am I supposed to get into iCloud? I plan on getting rid of my old email address which is my old Apple ID so how is that going to work?

Same question Wish someone had replied!
I changed my Apple ID to my new email and now cannot find any way to access icloud. Unfortunately I had allowed icloud to hijack my airbook files, so of course I am afraid I will lose them tomorrow when I exchange my iphone for a new one and cannot keep an icloud account i cannot access. What a poor sync system! Really atypical for apple!

I would like to transfer the balance from one Apple ID to another how can this be done??

I want to transfer the account ballance from my account to my son's. I unintentionally redeemed one of his gift cards to my account. how can this be done?

Sorry, but balances can't be transferred from one iTunes Store account to another. You'll either have to make his purchases through your account, or buy another prepaid card and redeem that in his account.
BTW, for future questions, this forum is for questions from those managing sites on iTunes U, Apple's service for colleges and universities to post educational material in the iTunes Store. You'll be most likely to get help if you ask in the general iTunes forums.
Regards.
