If you click a button to send ajax and limit the frequency of clicking the button, you can use 防抖動(dòng)
Instance analysis of debouncing and throttling
Make a timer. Click again if the time is less than the timer to cancel the last ajax sent.
The timer sets the click state of the button (clicking again within 3 seconds after clicking will have no effect), or define a state value and reset the state value when the callback is completed
