Convert Data From One Format To Another?

Oct 21, 2010

I am trying to convert data from one format to another. Starting with

Code:
X:1
T:Speed the Plow
M:4/4
C:Trad.

[Code]....

I am assuming I will have two textareas in a form, the data are copied from a clipboard to one of them and split into an array on newline characters. On the last few lines the letters A-G or a-g may or may not be preceded by _, =, or ^ and may or may not be followed by a comma or apostrophe then a (or not) number. The lack of a space after a letter indicates a grouping (beaming).

Does anyone have an example of some parsing code? Just something that looks at the input byte by byte building a token, putting a character back if it belongs to the next token and handling the end of the line and end of data. If someone has a parser for anything, I think I could adapt it.

Convert An Integer To Time Format?

May 6, 2010

Does JavaScript have an easy of converting an ordinary integer like 135 into a time format like 02:15? I'm working on a timer that handles the backend with just a plain integer that counts down every second but it needs to output looking like a clock.

Countdown Clock - Convert Resulting Milliseconds To Back To Time Format ?

Apr 28, 2009

teaching myself javascript. my current self-challenge is to write a countdown clock that will tick off the days, hours, minutes, seconds until a certain date.i'm thinking that this should be what's happening in the javascript:

get current date/time (using new Date())

get future date/time counting down to (using new Date(2009,7,7))

subtract current from future (Math.ceil(movie.getTime - today.getTime))

convert resulting milliseconds to back to time format (not sure how to do that yet)write result back to html page (not sure how to do that yet, either)loop the whole thing every 1000 milliseconds.is this a workable idea? it seems the most straightforward way of doing it, but other scripts i've found on the web seem much more complicated.

JQuery :: Ajax Returned Data Format ?

Sep 23, 2009

Getting information from a php file. Basically :

MY JAVASCRIPT FILE:

In this dumb example, I'm unable to match the 'data' returned variable with the value I assigned to it in php (I can't manage to enter my 'do stuff'), yet its value is 'ok' if I display it. I have no problem to retrieve html code from php and inject it in my pages, but I can't test it as a regular javascript string. 

What's wrong in this ? What have I missed about the 'data' format ? Do I have to 'cast' data to a javascript string (and if so, how ?)

JQuery :: Timezone - Get Data From System And Return In EU Format

May 21, 2010

I have my code php like that:
<?php
//Get the data from system and return in EU format
function ShowDate() {
$Date = date("d"."/"."m"."/"."Y");
return $Date;
}
//Get the time from system
function ShowTime() {
$Time = date("H".":"."i");
return $Time;
}
?>

Now I have two input box
<html>
<head>
</head>
<body>
Type the date:<input name="txtdate" type="text" class="input" id="txtdate" title="e.g dd/mm/yyyy" value="<?php echo ShowDate(); ?>" size="9" maxlength="10">
<br>
Type the time:<input name="txttime" type="text" id="txttime" value="<?php echo ShowTime(); ?>" size="5" maxlength="5">
<br>
London: Friday May 21 2010 05:12:00 <br>
New York: Friday May 21 2010 00:12:00<br>
Hong Kong: Friday May 21 2010 12:12:00<br>
Tokyo: Friday May 21 2010 13:12:00<br>
</body>
</html>

So.... the important is the user can interactive with the date. If I change the date or time all this values will be change as well. Someone knows how can I do this? The field txtdate I will get from a calendar plugin (javascript) that I already put in my code.

JQuery :: Json Considered The Better File Format For Loading Data Via AJAX?

Aug 14, 2011

Is Json considered the better file format for loadind data via Jquery AJAX? I am going to use it either way, but from a cutting edge stand point, is JSON looked at a more cutting edge since it loads faster. 2. And for that matter is anyone using css3 and E4X? All these seem to require the latest versions of all browsers. Since my goal is to be cutting edge I was thinking to do some stuff in the above listed that require only the latest browser if it is detected, if not use what works in most all browsers? What are cutting edge web app developers really doing at this time?

Convert 2 Characters - 2 Text Areas (input And Output) + "convert" Button

Aug 2, 2010

I would like to create a program which converts some letters into different ones.

1) I want 2 text areas (input and output) + "convert" button

2) if I type in the input area the letters "ea" I would like it to be converted into "a", so that If I type "cambrea" and press "submit" the output text will have "cambra".

3) if I type "e " which is (e+space) I want it to be converted into " " which is "space" example: if I type the word "spine " it should be converted into "spin , note that there is a space after "spin ".

4) If I type any vowel before "o" it should render "o", example: gambuo becomes gambo.
would this be possible? I'm not very familiar with Javascript even though I can modify it.

Convert Value To Integer.

Sep 25, 2007

function calculateGst(exGst) {

//percentage of current gst.
var gst = 10;

var gstAmount = (exGst * (1 / gst));
var gstInc = (exGst + gstAmount)

alert(gstAmount);
alert(gstInc);

}

now, the exGst parameter comes from an document.getElemenetById('txtExGst').value in an onclick event.

the problem is this. if 400 is entered at exGst, the gstAmount spits out 40, as it should, but the gstInc spits out 40040...so its treating it like a string rather than a number...
