js:

var s,  appwidget = {      settings: {         btnclass:   ".object",         main:       {},         btns:       {},         icon:       {},         current:    {},         next:       {},         prev:       {}     },      init: function(){         s   = this.settings;         m   = this.settings.main;         b   = this.settings.btns;           = this.settings.icon;         c   = this.settings.current;         n   = this.settings.next;         p   = this.settings.prev;         appwidget.binduiactions();         $(window).bind("resize", appwidget.resizewindow);         appwidget.resizewindow();     },      resizewindow: function () {       appwidget.setmaininfo();       appwidget.setcontent();     },      setmaininfo: function(){         m.btnc          = $(s.btnclass);         m.parent        = $(s.btnclass).parent();          b.owidth        = parseint( m.btnc.outerwidth(true) );         b.width         = parseint( m.btnc.width() );         b.margin        = parseint( m.btnc.css("margin").replace("px",'') );          m.iwidth        = parseint( m.parent.innerwidth() );         m.width         = parseint( m.parent.width() );         m.count         = parseint( m.btnc.length );         m.inrow         = parseint( math.floor( parseint( m.parent.width() ) / b.owidth ) );         m.rows          = parseint( math.ceil( m.count / m.inrow ) );         m.rowwidth      = parseint( b.owidth * m.inrow );         m.espace        = ((m.width - m.rowwidth) / m.inrow) / 2;         b.nmargin       = parseint( b.margin + ( ((m.width - m.rowwidth) / m.inrow) / 2 ) );         console.log(b.margin + m.espace);     },      setcontent: function(){         m.btnc.css({ "margin-left": b.margin + m.espace, "margin-right": b.margin + m.espace })     },      binduiactions: function() {         $(s.btnclass).click(function() {             console.log(this.id);         });     }, } 

it must in line, if comment line doesn't change back

            m.btnc.css({ "margin-left": b.margin + m.espace, "margin-right": b.margin + m.espace }) 

i tried kinds of stuf doesn't work :( me much, , saves time, thank much
