The specific steps are as follows: define a reference variable and add it to the ref attribute of the DOM element to be referenced. Use the $refs object in the mounted hook to access DOM elements. Note: Reference variables must be defined before the component is instantiated, DOM elements can only be accessed in the mounted hook, and the $refs object is read-only.
