在 jqGrid 中捕獲下拉的更改/單擊事件
[英]Capture change/click event of drop down in jqGrid
問題描述
我的下拉菜單上的點擊事件不會觸發。 我沒有看到警報，當我在 Firebug 中添加斷點時，它沒有到達斷點。 如果我斷點它們，它確實會到達單擊和雙擊事件。
具體來說，當我：
- 雙擊編輯一行
- 選擇客戶下拉菜單並選擇其他內容
- 移至另一行
然后線
alert("I changed");
不運行。
我想知道是不是因為當我移動到另一行時，值被恢復了（即使我已經注釋掉了restoreRow方法）
當我的下拉值更改時（無需更改焦點），我是否使用正確的事件來捕獲。

此外，目前還不清楚為什么您同時使用inlineNav和人工呼叫editRow內ondblClickRow ？ 如果您選擇行，然后單擊導航器中的按鈕，則不會調整dataUrl 。
您描述的主要問題的原因是dataEvents錯誤使用。 在editoptions的文檔中，您會發現dataEvents是editoptions的屬性，例如dataUrl 。 當前，您將dataEvents放在colModel的錯誤位置。
我建議您另外閱讀描述如何使用dataUrl哪些參數取決於當前所選行的答案。 此外，我建議您驗證您是否在dataUrl的響應中設置了Cache-Control （請參閱答案）。 或者，您可以使用此處描述的另一個選項。
