我有一個EXT窗體,它打開一個包含GridPanel的窗口,其中每次提交表單時都需要更新數據存儲區。網格顯示從客戶端計算機上傳的文件列表。所有這些工作正常,直到我關閉窗口並選擇一組不同的文件。我遇到的問題是當包含網格的窗口關閉然後重新打開時,它正在顯示先前加載的第一組文件,而不是從窗體提交的新文件列表。希望這是有道理的。我試過grid.getView()。refresh()但不更新網格。我試過grid.getView()。refresh(),但不更新網格。以下是我的窗口,窗體,網格和JSON商店的代碼。如果有人看到這個,我一定會欣賞一些建議。 (道歉的代碼格式...有很多的麻煩它是可讀的這個文本框)當窗口重新打開時EXTJS GridPanel內部窗口沒有從存儲中加載更新的數據
