[richfaces-issues] [JBoss JIRA] Commented: (RF-1282) Mouse wheel scrolling support for scrollableDataTable

[Pieter Van Nuffel (JIRA)]

    [ https://issues.jboss.org/browse/RF-1282?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12605704#comment-12605704 ] 

Pieter Van Nuffel commented on RF-1282:
---------------------------------------

I encountered this issue and created a workaround using the jQuery mousewheel extension: http://plugins.jquery.com/project/mousewheel

Make sure this code is executed once when the datatable is rendered to make scrolling work on the entire table:
(I hardcoded the tag id's, this can be improved to be more robust.)

            var innerPanel = jQuery('div[id = j_id197:resultTable:bc]');
            var scrollPanel = jQuery('div[id = j_id197:resultTable:scb]');

            jQuery(innerPanel).bind('mousewheel', function(event, delta) {
                var shift = delta * 30;
                var current = scrollPanel.scrollTop();
                //console.log(current + " " + shift);
                scrollPanel.scrollTop(current - shift);
                //don't let this scroll event continue to the entire page
                return false;
            });
