Changing Or At Least Detecting Character Encoding Via Javascript ?

Jul 20, 2005

I have a question if it is possible to manipulate the settings of
character encoding in Ms Internet Explorer 5.0, 5.5 and 6.0. The
problem is that the default instalation of Ms IE seems to have hard
selected default encoding to "Western European (ISO)", which means
iso-8859-1. When browsing pages with some Central/Eastern European
characters these are converted to iso-8859-1 so displayed wrong.

I would suppose the "auto-select" option should be default, so the
browser can select the right encoding according to the meta-tags in
the head of webpage. But this is apparently not true.

Please, is it possible to use JavaScript or Java applet to get the
information about the current client character encoding settings
and/or change it to the "auto-select" value ? How to do this ?

JQuery :: Character Encoding Not Being Transmitted By GetJSON?

Jun 11, 2010

I'm seeking to send this string via getJSON to my app:Academia-Gate the Nanny State & The Professors: My Brief Email Exchange With The Co-Chair of the Cry Wolf ProjectI have this code immediately prior to the getJSON call:

jQuery.ajaxSetup({ scriptCharset: "utf-8" , contentType: "application/json; charset=utf-8"});

Using Firebug, I can see that the text variable containing the above string, does contain it correctly, at the time it is used in my getJSON call. However, using breakpoints, I can see that when this text is received by my php app during the call made by getJSON, it looks like this:cademia-Gate the Nanny State & The Professors: My Brief Email Exchange With The Co-Chair of the ºCry Wolf ProjectHow can I correct this?

Detecting Non-Character Key Strokes?

Oct 21, 2010

I want to determine if a keystroke in a textbox was a character (a, X 3, &, etc) or not (SHIFT, CAPS, PrtScrn).....I am using String.fromCharCode(e.keyCode) for other things and I tried using it here in different ways (because these special keys always return a blank value with a string length of 1, but not a space??) but I can't get it at all.

Javascript Text Encoding/encrypting

Jul 20, 2005

MS has published on its sites javascript encoder, which enables "encrypting"
javascript code. It allows hiding js code from being seen as a text file.
There is a decoder for it, available in the net, freeware, srcdec14.exe.

I have tested both, encrypting, decrypting, the source and the final files
are identical.

But what I met on a certain site is a js file, encoded I think in another
way, because I cannot decrypt it using the srcdec14.exe.

This is why I have a question for genarally any information cons. this
subject (are there several ways MS is able to read encrypted js files?, do
you know other decoders?,...)

Changing The First Character To Upper Case?

Nov 21, 2011

this is what im trying to do:

Code:
var field01 = document.getElementById("Field01").value;
field01[0] = field01[0].toUpperCase();

it doesnt work, the first letter of the field stays lower case BUT when I do this:

Code:
alert (field01[0].toUpperCase());

then it converts the first character to uppercase, well only in the alert box, the actual one still unchanged.

so i figure thats because it needs to be triggered somehow, it wont work by assigning it. i cant use it as return. are there any trigger methods that would just let me capitalize the first letter without any pop ups or anything?

Detecting Image Dimensions With Javascript?

Nov 28, 2006

I have some CSS/javascript which takes an image and re-sizes it on a page with a hover-over state which causes it to expand. However, this will only re-size to specific proportions (in this case 1:1).

This is fine in the case of e.g. an 86x86 image but what I want to be able to do is detect if the image has a height greater than it's width, and if so, crop the image accordingly to make it a square.

Is there a way of doing this with javascript?

May 22, 2009

I have a HTML form which takes some values including a password field.

var iChars = "`<>";
for (var i = 0; i < document.ipform.password.value.length; i++) {

It's the first time I read the following code.
A few js files like the one below, but I don't know how to make them

Changing SRC With Javascript?

Aug 24, 2006

Basically, I'm trying to make a "chat-like" updater with javascript.

html.html includes the following:

<html>
<head>
<script>
var t;

function getData () {
document.getElementById("dataStore").href = "test2.html";
}

function update (message) {
getData ();
document.getElementById("txt").innerHTML= message;
t = setTimeout ("update ()",1000);
}
</script>
</head>
<body onload="getData()">
<div id="txt">hello</div>
<script id="dataStore" type="text/javascript"></script>
</body>
</html>
The file that it should get variables from is from test2.html, which is below:

var updateData = "hello!dasd";

update (updateData);
For this example, basically - I want javascript to change the "hello" in test.html to "hello!dasd" found in a variable in test2.html. This should keep asking for new updates from test2.html (which will be dynamic with php).

Latin Encoding In Ajax

Aug 1, 2006

I am trying to fill a dropdown menu with ajax, but the table
contains latin characters. In mozilla i get a weird black character
instead, and in internet explorer the whole code breaks because if a
word ends in a latin character then it ignores the <bri put on the
end, therefore affecting my data logic.

I am using results = http.responseText.split("<br>"); as a delimiter.

Is there a way to fix this without resorting to using xml encoding?

Email Encoding Script

May 22, 2006

I am working on/modifying a dom script to automatically convert e-mail addresses in the text format of username [at] domain [dot] com that are inside a pair of em tags into working mailto links.

the script works by getting all em elements in the document, checking to make sure they aren't empty and also that they contain the string s[at]s in them and then converts them to mailto links

the problem im having is that the script is skipping over every other em tag, so it is only creating mailto links for the 1st, 3rd, 5th, etc. em tags I know that the problem occurs in the final line of the function

ems[i].parentNode.replaceChild( a, ems[i] );

because i've added alerts through the code and i know that its cycling through all of the em tags correctly, but when it gets to that last line for some reason it is only replacing the odd ems. Code:
