Das richtige JavaScript POPUP

Mon, 12 Mar 2007 20:30:00 GMT

Ab XHTML 1.1 ist das tag target="_blank" nicht mehr erlaubt, weil der User selbst entscheiden soll, wie sich das Fenster öffnet. Ein Trick für Webmaster ist JavaScript zu nutzen. Und es ist egal, ob JavaScript deaktiviert ist oder nicht. Wenn JavaScript deaktiviert ist, öffnet sich das Fenster halt im selben Fenster wie der Aufruf.

Conversion to Content-Transfer-Encoding Quoted-Printable

Mon, 15 May 2006 10:21:00 GMT

This script will convert text to the Quoted-Printable type of Content-Transfer-Encoding that is commonly used for email. See RFC2045: "Multipurpose Internet Mail Extensions (MIME) Part One: Format of Internet Message Bodies for the description of this encoding type and others. A copy is at:http://www.ietf.org/rfc/rfc2045.txt?number=2045In particular, See "6.7. Quoted-Printable Content-Transfer-Encoding" in "Chapter 6. Content-Transfer-Encoding Header Field". Note that the standard supports representation of binary (non-text) data for this encoding type but it is not useful for it; therefore this script assumes the data is text. It is assumed that the end of a line is represented as CrLf, which is the standard for email and is used by Windows operating systems for end of lines.A summary of the algorithm is as follows. Character code numbers 33-60 and 62-126 are not converted and characters 9 and 32 (tab and space) need not be converted unless at the end of a line. All others are encoded by converting to hexadecimal preceded by an equal sign (character code number 61). Characters 33-60 and 62-126 are the exclamation mark through the tilde, excluding the equal sign. Following conversions of characters in that manner, encoded lines must not exceed 76 characters in length. An equal sign can be inserted at the end of a line to continue the line.The characters that are converted can include additional characters, depending on the application. Also the maximum line length can be different from 76 characters in length; the value 76 is used to ensure maximum compatibility. See the standard for details.The following HTML can be used to try the script.Quoted-Printable Content-Transfer-Encoding

IE Client Browser Offline/Online & Dial-up or Faster

Mon, 15 May 2006 10:20:00 GMT

Many of us would like to have Scripts or html pages which could be run OFFLINE on the clients PC when they are NOT connected to the internet. This is an example of how to check using some very SIMPLE HTML and JavaScript. Example you may have Gifs which you could reference in a default home page which could now be accessed offline via a directory on the clients system. Very Many possibilites with this. Please Rate this if you can and check out my other submissions here.Inputs:None//// Returns:This example just uses an ALERT BOX when the Browser is offline. you // can replace that with any logic you wish// , or just inform the person that they mu// st be online to use your Page or Script.// //// Assumes:Not only does this tell you i// f the Client PC is ONLINE or OFFLINE it // also tells you if the Client PC is Dial-// up or High-Speed. This means you could a// lso use this to determine Download optio// ns if your visitor is accessing your sit// e via a Slow speed dial-up line you coul// d re-direct to pages with less images ju// st for them so that pages would load fas// ter for dial-up visitors. Neat huh.No alert was added for this check however you can see that could be done very easily ;-)//// Side Effects:Joy to those of use whom// needed a way to take a diffenert path su// ch as getting Gifs, scripts from a direc// tory on the users hard drive when the us// er wishes to use our tools or applicatio// ns offline and the HTML is pointing to a// WEB Site for scripts of images.//This is a GREAT site to share ideas, code, and suggestions. Any Questions please email me at: Webmaster@Programming-Services.com Thanks Don Kennedy
