for details on this script, and how to use it on your own site.


Note this script can take a number of parameters. Parameters are stored in the wiktLookup object. Generally its a good idea to set parameters before the onload event is fired (some parameters it matters, others it doesn't). An example of parameters would be using the following js code (don't feel like you have to set all of them. they all have defaults. this is just an example):

if (!window.wiktLookup) wiktLookup = {};
wiktLookup.count = 1; //number of defn to return.
wiktLookup.showWord = bold; // to show what word we're looking up. one of bold, none, link
wiktLookup.noRedir = false;// true to stop magic (not mediawiki)-redirection. unrecomended
wiktLookup.audio = true;//  true, false, autoplay. NOT IMPLEMENTED
wiktLookup.width = 500; //  width of box. make sure number not string. in units of pixels.
wiktLookup.height = 400; //- height of box
wiktLookup.key = 'w';// - ctrl+shift+key makes box popup (should be lowercase. default is 'l')
wiktLookup.reverseShift = false; // - if set, requires shift+double click to lookup a word.
wiktLookup.mode = context; // - context, bottom. default to context. to display as tooltip, or at bottom
wiktLookup.definitionBegin = 'Definition ('; // - for i18n. in english it is 'Definition ('. used in mode='bottom'
wiktLookup.definitionEnd = '):'; //  - for i18n. in English it is '):' used in bottom mode
wiktLookup.hideText = 'hide'; //- for i18n. in English it is 'hide'. used in bottom mode.
wiktLookup.exit = true; //have a hide link.
wiktLookup.disableByDefault = true; //enable only in <span class="wiktLookup-enable">blah</span> sections.
