How to control large number of ajax requests?
I have a element when click, it will trigger some other elements to be selected.
and those elements will trigger elements in next level.
It is a three levels hierarchy so to speak.
but each element will send an ajax request when selected.
Those requests will become out of control especially when I repeatedly click the root element.
Can I queue those XHR request in a queue and send them one by one?
or maybe add a delay before send so that they can collect their information into one batch request and send one request after that.
Please advice. Thank you very much.
