For example, pretend that the variable was just introduced. And if there is an unbalanced number of curly brace '' characters, or any other parse problem, the whole URL will just get reset to an empty string.A URL template like this could be used to make sure it had no effect on older toolbars: It should also be noted that any time an escape is used that is not recognized, the parser will substitute an empty string. Most icons that are used as favicons can also be used as custom button icons.You can display a small amount of status text next to the title of a toolbar button using a toolbar-specific namespace extension to RSS or ATOM.If the user has button text turned off, the status text will still show next to the button.A small text icon appears on the custom button icon when text is selected.This operation requires the Custom buttons with send operations will also appear on the right-mouse-button context menu of the browser when text is selected.Here is an example of a mood ring button that pulls from a feed: AAAAAAMAAAABAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAACAAAAAw AAAAMAA AAABAAEAEBAAAAEAIABo BAAAFg AAACg AAAAQAAAAIAAAAAEAIAAAAAAAQAQAAAAAAAAAAAAAAAAA AAAAAAAAAAAGAAAAHAAAAEAAAABh AAAAcw AAAHQAAABp AAAAVQAAAD4AAAAp AAAAGAAAAAo AAAAD AAAAAQAAAAAAAAAAAAAAESZIXl4zd Jv AXb HS8m3C3f9Lnrr LFUtsmw ILEX4AAABz AAAAYQAAAEc A AAAq AAAAEw AAAAc AAAACAAAAACs9RTNOjr Dt W6n S/53u/f n/P//hej//2b P/P9Fq93w HGa Nrx Ev O4k AAAB6AAAAXw AAADw AAAAf AAAADAAAAANiha WST6XK/0h/kc Ad KCy WKTt Ag VJ/k Ihyt NKse873 9E w6v9Ru N39SXu Jpg QHCIo AAAB2AAAAUQAAACs AAAAPb6n U7m K65v9jqs76Kk NPq AUICJo AAACE AAAAax Ug JWBkr Miwsvv //D /v y1Nni Ij1Fn AAAAIg AAABc AAAALHS74PV1z Pn/c835/1Oezv9N iq7v NVRjrx Ui J5k BAg ORAQICh3u Lj Zz3 vr1 f///4PL5/wv Vmus AAAAig AAAFNyu TPdt L8/0Cp 7v8ng8X/CFOH/ytpjv86g J//R46z Th6jsov Vm Csd56px Nf2/f9Tu PH/W7fs/yp GV6UAAAByf77Y r02y7P9Zwfb/pu H3/y At P8j Z5f/KWKH/0p7h P Zr Vr/zc Ut/9v MKf/bz Sz/ts BP/3Ozr P9kl7Pp AAAAg HGdp Thatu T/0fn //b/// V0uv/NICu/4mvf P/czj L/3M0v/9r MKP/dzz T/3c83/9v NLf/b z S//nr WA/g AAAIMAMz MFbrrd2d/ ///5////t n6/4q6nf/czz X/3t A /97QPf/czj P/3d A7/97R Qv/czj D/3M4z/9DHLPo AAAB/AAAAAWSht Uix5 //5v7 /5Hf7//Bvjn/3M0v/9/SSP/g1FL/39RR / DVWv/e0kf/3t FA/9z NL//bz Cj/AAAAbw AAAAAAAAADcq7Fmpzo8f9rs L3/2ssl/93POf/f0kj/ 49pu/ ffh P/q45b/49pp/97SSv/cz S//yb0q4w AAAE8AAAAAAAAAAF54hh Nrq77BXp Cj/7 7Of/c zj H/3t FH/ bde P/w7cv/9PLa/ zlnf/g1VP/1so5/m Bf JHs AAAAr AAAAAAAAAAAAAAABa5Gg IHWs t/dym G3/3t E//9/UUv/o4Ij/9PHT//v67P/v6a3/08x Y/3u MX6UAAAAu AAAAEAAAAAAAAAAAAAAA AAAAAAKSvb9YSo Wa Wyag P wv2X/4NRO/ ngfv/m4Zf/r Le B lpub Ik AAAAl AAAADg AAAAMAAAAA AAAAAAAAAAAAAAAAAAAAAoqvu Dxkkp2g Yo c51m Hkv9lk5v/Y4e Ntl Bfa Eg AAAAWAAAACQAAAAIA AAAAAAMAAAABAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAACAAAAAw AAAAMAA AADg AAAA8AEAAA== The icons should be in the same folder as the script.
This could be useful for a translation service, or maybe a blogging or messaging application.
To do this, add a search element in the form attribute in the search element. Also, it is possible to send CGI parameters and post data at the same time -- to do this, use two question mark '? This example uses a post method to send postdata (highlighted): The download URL you use to host the XML file for the button becomes the button's unique ID for updating the button.
If a second attempt is made to download a button from the same URL, the toolbar will offer only to replace the old one, not add a new one.
There are several sites on the Internet that will do the encoding for you -- for instance, this one.
On that site, use the "Browse..." button to select the file you want to encode, then click the "Convert the source data" button to start the encoding.
