我怎样才能做到这一点? :D
解决方法
将“height”,“marginTop”,“marginBottom”,“paddingTop”和“paddingBottom”设为“显示”.
例如:
$(...).animate({ "height": "show","marginTop": "show","marginBottom": "show","paddingTop": "show","paddingBottom": "show" });
来源:jQuery源代码
fxAttrs = [ // height animations [ "height","marginTop","marginBottom","paddingTop","paddingBottom" ],// width animations [ "width","marginLeft","marginRight","paddingLeft","paddingRight" ],// opacity animations [ "opacity" ] ]; ... jQuery.each({ slideDown: genFx("show",1),slideUp: genFx("hide",slidetoggle: genFx("toggle",fadeIn: { opacity: "show" },fadeOut: { opacity: "hide" } },function( name,props ) { jQuery.fn[ name ] = function( speed,callback ) { return this.animate( props,speed,callback ); }; }); ... function genFx( type,num ) { var obj = {}; jQuery.each( fxAttrs.concat.apply([],fxAttrs.slice(0,num)),function() { obj[ this ] = type; }); return obj; }
