本文实例讲述了jquery插件实现控制网页元素动态居中显示的方法。分享给大家供大家参考。具体实现方法如下：
(function($){ $.fn._center = function(self, parent, dimension) { if(!dimension.vertical && !dimension.horizontal) return; //won't do anything anyway if(parent) parent = self.parent(); else parent = window self.css(position, absolute); if(dimension.vertical) { self.css(top, math.max(0, (($(parent).height() - $(self).outerheight()) / 2) + $(parent).scrolltop()) + px); } if(dimension.horizontal) { self.css(left, math.max(0, (($(parent).width() - $(self).outerwidth()) / 2) + $(parent).scrollleft()) + px); } return self; }; $.fn.center = function(parent, args) { if(!args) { args = {horizontal: true, vertical: true}; } return this.each(function() { var obj = $(this); obj._center(obj, parent, args); function callback() { obj._center(obj, parent, args); } callback(); $(window).resize(callback); }); };})(jquery);
希望本文所述对大家的jquery程序设计有所帮助。
