The invention discloses a method and device for processing webpage activities. The method comprises the following steps that module selecting instructions of a user are received, and corresponding functional modules are obtained, wherein the functional modules comprise condition limiting interfaces for achieving interaction among the functional modules and task executing interfaces for executing tasks corresponding to the functional modules; setting information of the user is obtained, the functional modules are associated through the condition limiting interfaces of the functional modules according to the setting information; the tasks corresponding to the functional modules are executed in sequence through the task executing interfaces of the functional modules. The method and device for processing the webpage activities save the development cost of the webpage activities, improve the utilization efficiency of the developed webpage activities and effectively lower the error rate of the webpage activities.
