Do Until Loop

Hello,
I am wondering if a Do until loop can be used in Javascript. I have an
array and want to fill the array 10 times with the users details until
it reaches 10 or if they press cancel. I'm using window.prompt to get
user info. Any suggestions.

Do {
//ask user to input their details
} while (myairline !=10);

JS ist case-sensitive. `do' instead of `Do' works OK.
Learn from this:

var i = 10;

do
{
alert(i);
}
while (--i);

What are you talking about? The above loop will be executed exactly 10
times. And if you are referring to the condition: any while-condition
can be _literally_ inverted to an until-condition:

do
alert('as long as condition applies')
while (condition);

do
alert('until condition applies')
while (!condition);

Then why didn't you post script code this time? The code itself is
exactly the same.

When correcting yourself, you should reply to yourself.

Top-posting is *never* acceptable. Even when correcting oneself.

Hi, Thomas, I was not referring to your code.

Just making a joke as such.

I did, read again.

It is not, read again.

No, you should not. There are three prudent ways when this happens
(I think we agree that it should not happen in the first place.)

A) Supersede the article to be corrected so that the new article
will be posted and the old article be canceled automatically
by the news server because of the Supersedes header it contains,
specifying the old article via its Message-ID.

B) Cancel the old article and repost it. Virtually the same as A),
however it is supported by news servers that support the Cancel
control message and not the Supersedes header. (However, both
are specified in Son-of-RFC-1036, the quasi-standard Usenet is
based on.)

C) Reply to the erroneous article. Only necessary on very large
postings where little is to be corrected and a complete repost
would waste bandwidth. Since the advent of Usenet spam, there
should not be one _public_ news server or Web interface out
there that disregards Cancel control messages, even though they
are only part of the quasi-standard.

I did A), using my newsreader's built-in feature that works perfectly
since the old article was indeed canceled. What is your excuse?
Top-posting is *never* acceptable. Even when correcting oneself.


I was _not_ top-posting, read again! And learn to understand the
concept of submitter's note, unless you want to make a complete
fool of yourself here.

this works for me:

do

details[myairline]=prompt("Enter details for Airline "+myairline );
myairline++;
}
while(myairline <10);
