layer.open({
	 type: 1,
	 title: false,
	 shadeClose: true,
	 area: ['400px', '350px'],
	 content: $('#box'),
	 success: function(layero){
	     //layer樣式layer-anim導致全屏樣式錯亂，移除該樣式即可
	     setTimeout(function() {
	      $(layero).removeClass('layer-anim');
	     }, 0);
	 }
});
 

這樣就ok了，當然，這是需要jar包支援的，需要下載 layer.js。 這個jar包的原始碼我給列出來了，直接copy到檔案中 改個名就行了
