更新反映在數據庫中，但不是SELECT查詢

Question

第一次來我這裏。

我使用PHP，MySQL和JavaScript和運行jQuery和AJAX功能。

我有一個運行功能的錨鏈接。

該函數將會清空DIV標記，然後填充/顯示器（SELECT查詢）行的表中DIV與爲空where子句。每行都有一個選擇框，其中NULL數據列將放在哪裏。選擇框中的數據來自不同的表格。

當選擇框改變它立即運行AJAX在選擇框中輸入新的數據來更新錶行。

當你點擊鏈接再次運行功能（空，選擇查詢和顯示基於空列），這是剛剛更新到數據庫的行顯示再次基礎上，爲空子句。在這一點上檢查數據庫表顯示它實際上不是空的，並在第一次出現時進行了正確的UPDATE。

頁在此過程中從來沒有刷新，從來沒有要。如果我刷新它顯示沒有BUG的正確數據。

所有你的想法，不勝感激。

的jQuery緩存您的Ajax調用。這很可能是您刷新頁面時看到正確結果的原因，而不是在通過ajax進行的後續調用中。

嘗試在ajax call
