利用art.dialog id将art.dialog关闭方法

 $(document).on("click",".withdraw",function(){
	      		var href=$(this).data('href');
	      		art.dialog.loadCall(href, {
	               id: 'showdesc',
	               title: "设置为已提现",
	               width:'750px',
	               lock: true,
	               close:function(){aTable.fnDraw()}
	           	},
	           	false,function(){});
	           	return false;
       	  });//弹出一个对话框之后

        art.dialog({id:'showdesc'}).close();}//可以利用art.dialog的id属性将其自动关闭
