使用时,我收到以下错误:
$('#topo').scrollFollow();
TypeError: Cannot read property 'top' of null
arguments: Array[2]
get message: function () { [native code] }
get stack: function () { [native code] }
set message: function () { [native code] }
set stack: function () { [native code] }
type: "non_object_property_load"
__proto__: Error
那么,我该怎么办呢? :d
