jquery - unaffix event for Bootstrap affix? -

-

i want combine affix plugin bootstrap navbar-fixed-top class. far have got working when scroll past navbar gets fixed. when scroll want go static state again. have seen code think older bootstrap versions , unaffix event. why gone? can create one? or how accomplish trying here?

navbar_secondary = $( '.navbar-secondary:first' );  navbar_secondary.affix( {     offset: {         top: function () {             return (this.top = navbar_secondary.offset().top )         }     } } );  navbar_secondary.on( 'affix.bs.affix', function () { // wrong event this. want fire when *not* affixed     console.log('affix');     navbar_secondary.removeclass( 'navbar-fixed-top' ).addclass( 'navbar-not-fixed' ); } );  navbar_secondary.on( 'affixed.bs.affix', function () {     console.log('affixed');     navbar_secondary.removeclass( 'navbar-not-fixed' ).addclass( 'navbar-fixed-top' ); } );

figured out myself. event names totally confusing. affixed-top.bs.affix event when goes being not affixed.

navbar_secondary = $( '.navbar-secondary:first' );  navbar_secondary.affix( {     offset: {         top: function () {             return (this.top = navbar_secondary.offset().top )         }     } } );  navbar_secondary.on( 'affixed-top.bs.affix', function () {     console.log('unaff');     navbar_secondary.removeclass( 'navbar-fixed-top' ).addclass( 'navbar-not-fixed' ); } );  navbar_secondary.on( 'affix.bs.affix', function () {     console.log('aff');     navbar_secondary.removeclass( 'navbar-not-fixed' ).addclass( 'navbar-fixed-top' ); } );

summary

affix.bs.affix => before fixed positioning applied element
affixed.bs.affix => after fixed positioning applied element
affix-top.bs.affix => before top element returns original (non-fixed) position
affixed-top.bs.affix => after top element returns original (non-fixed) position
affix-bottom.bs.affix => before bottom element returns original (non-fixed) position
affixed-bottom.bs.affix => after bottom element returns original (non-fixed) position

i have implement video collection website users of specific isp. site hosted on public web-server movies hosted on local isp server. user of isp + general visitors can see available movies; isp's users able play them. player on site point url of local machine ( http://192.x.x.x/movies/mymovie.mov ) private class (192.x.x.x) accessible isp user. question: possible phpmotion script? or need custom work. if possible, can please suggest available mods? phpmotion require modifications able handle this. uploading, conversion, thumbnail generation, , playback pretty static in phpmotion. really though, rather modding entire upload , conversion process, if created quick custom form add entries phpmotion database (maybe include thumbnail upload), tweaked playback paths, should go on phpmotion side of things. assume had videos in format player handle (such flv or mp4).
