/*********************************************************************************************** Script taken from some third party site The script has been modified by Steve Curry to meet the requirements. ************************************************************************************************ To swap between stylesheets: changeStyle(); //switches off all stylesheets that have title attributes changeStyle('Default'); //switches off all stylesheets that have title attributes that do not match 'Default' changeStyle('High Contrast'); //switches off all stylesheets that have title attributes that do not match 'High Contrast' changeStyle('Big Font'); //switches off all stylesheets that have title attributes that do not match 'Big Font' changeStyle('High Contrast','Big Font'); //switches off all stylesheets that have title attributes that do not match 'High Contrast' or 'Big Font' Opera 7+ and Mozilla also allow users to switch between stylesheets using the view menu (only one at a time though ...) To make the script remember the user's choice of stylesheets, for example to use on more than one page or if they reload - includes stylesheets chosen using the view menu in Gecko - it will only attempt to store a cookie if they actually changed something: In these examples, I call the cookie used to store the choice 'styleTestStore'. You could use any name you like. To remember only until the browser window is closed: To remember for 10 days (for example): _____________________________________________________________________________________________*/ function getAllSheets() { if( !window.ScriptEngine && navigator.__ice_version ) { return document.styleSheets; } if( document.getElementsByTagName ) { var Lt = document.getElementsByTagName('link'), St = document.getElementsByTagName('style'); } else if( document.styleSheets && document.all ) { var Lt = document.all.tags('LINK'), St = document.all.tags('STYLE'); } else { return []; } for( var x = 0, os = []; Lt[x]; x++ ) { var rel = Lt[x].rel ?
