/* class Keynav ;-) Enables the user to navigate via arrow keys and/or Page Up/Page Down keys. It is also possible for the user to either enable/disable this feature. To enable this permanent, you have to comment out an if-block below (see comments in code). Use something like this in your HTML Code if you want to let the user decide if or not to use keynav: and */ /** * void tastendruck() * @PARAM Event ereignis * Jumps to next or previous Page, depending on which arrow key has been pressed */ function tastendruck (ereignis) { // comment out first if-block to enable keynav permanent //if (document.cookie == "true") //{ if (!ereignis) { // init object if none exists ereignis = window.event; } switch (ereignis.keyCode) { // enter case 13: jumpToPage(); break; //pagedown //case 34: //right case 39: window.open(myNextPage, "_parent"); break; //pageup //case 33: //left case 37: window.open(myPreviousPage,"_parent"); break; case 38: parent.centerFrame.scrollBy(0,-30); break; case 40: parent.centerFrame.scrollBy(0,30); break; } //end of if-block to comment out to enable keynav permanent //} } /** * void checkCheckBox() * Checks if cookie is present. * If true, then keynav and checkbox are enabled * If false, then keynav and checkbox are disabled */ function checkCheckBox() { keyNav = false; if (document.cookie == "true") { keyNav = true; } document.getElementsByName("cb")[0].checked = keyNav; } /** * void setCheckBox() * Sets cookie true or false if checkbox is enabled/disabled */ function setCheckBox() { cb = document.getElementsByName("cb")[0].checked; if (document.cookie == "true") { document.cookie = "false"; cb = false; } else { document.cookie = "true"; cb = true; } location.reload(); } // Catching Event document.onkeydown = tastendruck; // end class Keynav ;-)
