Front-end timing polling task multi-component linkage triggering method and device and related medium

The invention discloses a front-end timing polling task multi-component linkage triggering method and device and a related medium, and the method comprises the steps: setting a front-end component of query equipment as a target component, and setting a first timer in the target component; when the first timer of the target component triggers query, querying and judging whether data update occurs, and acquiring updated data after judging that the data update occurs; determining an associated component associated with the target component, and setting the associated component to monitor the target component to obtain the update data; and when the associated component acquires the update data, the associated component performs updating according to the update data. According to the embodiment of the invention, the timer polling is set in the target component, the component information is updated when the polling is triggered, and other associated components monitor the information change so as to trigger the que
