Need An Ascii Image Format!

Jul 23, 2005

I developing a system using JSP. People familiar with this technology
know that ServerPages are easier to maintain than Servlets, but they
can only have ASCII output.

With that as the backdrop, here's what I want to accomplish. I want
clicking on a link to cause a script to be executed on the server but
-->I don't want the browser to jump to another page<--.

A solution that I conceived was to have javascript like

someimage.src = 'http://myscript'

This will accomplish the task and it would be great if myscript return
an image of a checked checkbox! But, because of JSP limitations this
would need to be an ASCII image.

So my question is twofold:

1. Are there convenient ASCII image formats?
2. Is there another way to accomplish what I want (trigger some action
on the server without jumping to another page and using js to display
a sensible response - something like a check)?

Slide Show Gets To The Last Image After The Last Image All Photos Disappear And It Resets Itself Changing The Format Of The Webpage

Jun 12, 2009

I found this slide show [URL]. I got it to work on my website [URL] using Firefox, but when it is viewed in Internet Explorer it will not work. Second question, When the slide show gets to the last image, after the last image all photos disappear and it resets itself changing the format of the webpage. Any way to not have the images disappear while it loops itself or is there a code to have it stop on the last photo and not loop.

Grabbing ASCII Values In A Text Box

Mar 10, 2006

I have a function that lets me convert one character and throw an alert
with the corresponding ASCII value, but what I am having trouble with
is applying it to a text box. What I'm trying to do is when characters
are entered the function will loop through the entered values and throw
an alert for each of the corresponding ASCII values for each of the
characters entered. I am trying to alert the user for every character
that is out of the range of ASCII equivalent 1 - 128. Test code:

Unicode Escape Non-ascii Chars?

Jan 1, 2009

I'm looking for a function that will convert non-ascii characters to unicode escaped string.For example, "あ" => "u3042".A similar piece of code is below. However, it convert strings to "\uxxxx" instead of "uxxxx". Changing "\" to "" in code below still won't work because that result in 'u' + 'xxxx' which print as "uxxxx".I have been searching for a few days already, and start wondering if this is at all possible. ; (

Code:
var unicodeEscape = function(str) {
var code, pref = {1: '\x0', 2: '\x', 3: '\u0', 4: '\u'};

Need To Convert From Ascii To Its Ingeger Number

Jul 8, 2010

I have a quastion, I am currently passing in a number as a string to my function (this is hard to change since its a program that generates the numbers).

For example i pass the number function random('252'), but what I want is this
function random(252).

So my quastion is, do you guys have a clever idea on how to take this string, this ascii number and convert it to its "real" integer value, so that i can make correct calculations?

Displaying Upper ASCII (code 128-255) In Alert() Window.

Jul 23, 2005

Most of these characters are not on the standard keyboard.
Here's a successful contrivance, with comments & cautions,
a little page that works in IE6.

<HTML><HEAD><SCRIPT TYPE="text/javascript">
function alt() {
document.all.s1.innerHTML="Current Temp: 68F";
var txt=document.all.s1.innerText;
alert(txt);
}
</SCRIPT></HEAD>
<BODY>
<INPUT TYPE="button" VALUE="Temperature" onClick="alt()">
<P ID="s1" STYLE="visibility:hidden"> </P>
</BODY></HTML>

comments: The innerHTML property is needed to produce the
character glyph from the entity code. If the entity string
were passed to innerText(in 1st statement) then the code
would remain literal.

This work-around depends on s1 being rendered before alt()
is called. It will not work as immediately executed code,
because element s1 would not exist yet.

cautions: Trying to style alert's display will produce error
msgs. Do not use <B>, <U>, or <I> tags in the argument
string. No Heading tags either.

Strange enough, an inline STYLE, setting font values, say,
does not give error msg, but will not execute either.
Alert ignores it.

You can use <BR> tags in the argument, which give the same
result as
in a direct arg to alert().

In sum, you can tell alert what characters to display,
in what order, and on what line, but you cannot tell
alert HOW to display them.

AOL Email Format?

Apr 21, 2001

Quick question: I have a simple script (PHP) that emails users information along with a URL. This URL is encoded with characters and is extremely long, and needs to be clicked on by the user, as is, from within the email.

I have noticed that email clients like Hotmail, Yahoo! mail, and even other app. based clients allow the user to directly click on the URL. However other users, especially AOL users, are having problems clicking on this URL.

Does anyone know how to embed URL's within an email for AOL users? I know its a bit different because whe I receive newsletters, they normally have a separate link for AOL users.

GET Message Format HTTP

Jul 23, 2005

I wondered what the text before the get text signifies? I imagine they are
variable names and parameter values.

Is this correct?

Would someone tell me how I can go about decoding them (or give a
reference(s)), so I can find out what I should actually send in the GET?

Here is a sample of format of the instruction I have trapped.

AlphaIDs=&origin=placeAlpha&SelectionIDs=20930%7C&BidTypes=B%7C&Part=10%7C&N

Get/format Date Field

Jul 23, 2005

I have an asp page that uses a calendar.js (pop-up) file to add an
exact date format in the text field (txtDDate). My problem is I need
some javascript that sets an alert that does not allow them to select
today.

example:
var dtToday = Date()
if(document.frmSoftware.txtDDate.value == dtToday)
{
alert("You cannot select same day distributions. Please enter a new
value in the "Delivery Date" field.");
return false
}

But dtToday is blank....How can I get dtToday value? Also, when I set
the dtToday value outside javascript and used a Response.Write to see
what format Date() came up with - it gave me 1/24/2005 - but the
calendar pop-up gives me 01/24/2005....could this also be the issue?

Function Format Question!

Jun 28, 2007

I was wondering if someone could give me a brief explanation as to what the differences are between the following.... i'm guessing that the second example is more for Object-Oriented programming? Why would it be better than the first (the inherited code I'm looking at has almost all functions defined in the second format)

first:

function saveFinal(){

if (confirm("would you like to save your completed chart?")){
window.location="savereport.php";
}

}


versus the second:


saveFinal = function(){

if (confirm("would you like to save your completed chart?")){
window.location="savereport.php";
}

}

Date Format Changed In IE7 But Not In FF?

Jun 3, 2009

After fetching a timestamp via sql,I return to javascript to do the formatting. Actually, I was first doing a bit of formatting in php to change from yyyy mm dd hh:mm (as saved in db) to mm dd yyyy hh:mm as I found the 1st not to work with the Date() function in FF.Consider the following...

var date_from_server = "06 03 2009 01:37";
var jsDate = Date(date_from_server);

In FF jsDate is "Thu Jun 03 1909 01:37:00 GMT-0700 (Pacific Daylight Time)".In IE7 jsDate is NaN.I've tried a few different formats. Does IE7,s Date() function not allow an arg at all or only of a certain format?
