    Listing hotKeys active for a page

    supernovasoftware.com Nov 14, 2008 1:49 PM

      Is there any way to list the currently active rich:hotKeys for a given page using javascript or otherwise?

      I would like to let the user see what hotKeys will work. This could be a modal panel or tool tip or whatever.

      I might be nice to add a title, or description to rich:hotKey so that this could be displayed as well.

      Thank you for your advice in advance.

          Hi,

          Try this:

          <body onload="showMappings()">

 <rich:hotKey key="alt-a" selector="span" />
 <rich:hotKey key="shift-b" selector="span" />
 <rich:hotKey key="c" selector="span" />

 <script type="text/javascript">
 function showMappings() {
 var mappings = {};
 var all = jQuery.hotkeys.all;
 if (all) {
 for ( var name in all) {
 var elt = all[name];
 if (elt.events) {
 for (var eventName in elt.events) {
 var combi = elt.events[eventName];
 if (combi.callbackMap) {
 for (var key in combi.callbackMap) {
 mappings[key] = true;
 }
 }
 }
 }
 }
 }

 var result = new Array();
 for (var mapping in mappings) {
 result.push(mapping);
 }
 alert(result);
 }
 </script>
...
</body>

            That works quite nicely.

            Thank you for the tip.

            I would now like to display some information about what the hotkey will do.

            I guess I could tie this to my messages, but different hotkeys could do different things on different pages.

            Any advice on the best way to implement this?

              As for me I think messages is a good enough to perform this. You could just create alternate messages for some hotKeys which could be defined with the different meaning.
