我需要我的用戶流每10秒更新一次以更新諸如來自其他用戶的新插入狀態，時間戳和最新添加的評論數量等內容。Ajax輪詢只更新數據
現在我可以使用下面的，但是我面臨的問題是當我發佈到textarea中時，需要插入用戶帖子的狀態需要10秒，之後每十秒鐘添加一次相同的狀態。 。只是在不同的ID。
我需要的所有輪詢都是選擇在insert.php頁面中輸出的數據，而不是每隔10秒添加一條新評論。是否有可能採用這種不同的方式來選擇響應數據？

對不起，但我仍然不知道你的問題是什麼。你可能也可以發佈HTML頁面的代碼不僅僅是PHP和JavaScript代碼。我的意思是homestatusid被定義的部分。 – Preli 2012-08-04 17:21:18
它很長。但是我更新了我的代碼。 – dave 2012-08-05 06:32:08
