sx：autocompleter onchange沒有調用JQuery函數

我正在使用Struts2 + Spring MVC + Hibernate，我試圖創建一個依賴的下拉菜單。但是，我的JQuery函數只在頁面啓動時被調用，而不是在第一個菜單中選擇了一個選項時調用。組織下拉菜單工作正常。這裏是相關代碼：sx：autocompleter onchange沒有調用JQuery函數

search.jsp的

由於Ajax and JavaScript recipes show要設置的適當屬性是loadOnTextChange。

請記住，這些是Dojo小部件，而不是簡單的HTML控件–您不一定使用標準HTML屬性來修改它們的行爲。

如果您使用的是JSON，請參見recipe for JSON results;它可以比你做得更簡單。

loadOnTextChange無法正常工作......我只是在操作上使用System.out.println來查看它是否再次調用，但它只是在啓動時調用。您給他的幫助很有幫助，之前我遇到過，但是我在使用Spring MVC時遇到了麻煩。 – user1287523

@ user1287523 Spring MVC與這些有什麼關係？我真的不明白你要做什麼 - 如果你試圖在jQuery中使用Dojo小部件，那麼你做錯了。 –

我見過的大部分教程都要求我創建一個包含兩個類的新操作類。但是我不能實現兩個不同的VO文件。我知道我做錯了，因爲我對此很新。我希望如果我顯示我的代碼，我可以得到有關如何做的建議。 – user1287523
