Intelligent Chat question and answer stream typewriting output method and system implemented by pure front end

The invention relates to the technical field of typewriting output, and provides a Chat intelligent question and answer stream typewriting output method and system realized by a pure front end, and the method comprises the steps: defining a stream typewriting output method class, and setting a dependency attribute and a control method in the defined stream typewriting output method class; a default constructor function of the streaming type typing output method class is adopted, and parameters input from the outside are received to update dependency attributes of the streaming type typing output method class; and controlling the execution of the streaming typewriting output method according to a control method set in the streaming typewriting output method class and the updated dependency attribute. According to the Chat intelligent question and answer stream typewriting output method and system realized by the pure front end, intelligent question and answer stream typewriting output which is easy to control,
