May 1, 2009 how I can get this lookup to work..:?I'm using a app that uploads an image and returns a hex code in a 3x3 grid. (See here: http://jrm.cc/color-palette-generator) I want to take this one stage further and have a code that will then take the Hex code and look up a field in an sql database containing hex codes. Then convert the hex code into an image containing the selected colour. For example;
User uploads image of the sky
App returns hex codes of sky
App then needs to look in a field database of images on server and finds image/s with similar hex value
App then returns images in replace of the hex code (i.e blue water, swimming pool, blue coloured hat etc etc)
Base64 Strange
May 14, 2007I'm trying to send a byte array (JPG image) from javascript to a servlet for processing. I'm using Base64 to encode the byte array in javascript, and then a base64 decoder in the servlet to decode it.
The thing is, that even though the String has the same length on both sides, the decoded byte array is shorter then the original one. I've tried a couple of different implementation on both sides, with the same results.

Feb 16, 2009How do I convert an image or datauri to canvas? I see the other way at [URL], but I also want to find out how I can create a canvas at the first place.The reason I ask this question is because I would like to create a little app that lets user create a canvas 'image', save it as something and be able to reopen it for canvas modification in the future. I figured that datauri is a good way to save a canvas, but I am not sure how I can do to reopen the datauri and use canvas to modify the drawing.

JQuery :: Character Encoding Not Being Transmitted By GetJSON?
Jun 11, 2010I'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 Cry Wolf ProjectHow can I correct this?

View 3 Replies View RelatedJQuery :: Textarea/Textbox Html Content Encoding To Satisfy .Net 4.0 Validation Test
Sep 19, 2011I have web form (not MVC) that has bunch of textarea and textboxes where user can input HTML markup. For example, a textarea is provided so users can put YouTube embed iframe html tag where it will be shown on their profile. The problem is that asp.net 4.0 http request validation doesn't like things like ">" or "<", etc. I can put pagevalidation="false" on the page and/or revert back to .net 2.0 validation but why would I want to do that since I have geniuses like you guys that can show me how to do what I want with jquery without jeopardizing security.
So what I want to do is form a handler so when the form is submitted, the content of the textboxes and textarea on the page be encoded (i.e. > to > etc.) before the submission to the asp.net 4.0 so we can keep the httprequest validation stuff happy. I have added a class "mustEncode" to each of the textarea and textboxes.

Latin Encoding In Ajax
Aug 1, 2006I 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, 2006I 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:

Aug 2, 2010I 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.
Javascript Text Encoding/encrypting
Jul 20, 2005MS 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 Or At Least Detecting Character Encoding Via Javascript ?
Jul 20, 2005I 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 ?
