For example, both of them can be used for statistical usage purposes, tracking the number of clicks on certain links of a page, measuring the amount of time an element is focused, and so forth. In addition, when combined with AJAX technology, they help minimize the number of requests to the server, depending on the user activity and the page layout.", "sections": [{"id": "Browser_compatibility", "title": "\u30d6\u30e9\u30a6\u30b6\u5b9f\u88c5\u72b6\u6cc1"}, {"id": "Browser-specific_notes", "title": "Browser-specific notes"}, {"id": "Gecko_notes", "title": "Gecko notes"}, {"id": "See_also", "title": "\u95a2\u9023\u60c5\u5831"}], "id": 32895, "review_tags": []}
