我有一個帶有一些級聯下拉菜單和提交按鈕的web窗體。在點擊提交按鈕時,我從數據庫獲取數據。整個webform在包含按鈕的更新面板中。jquery在頁面部分回發後隱藏/顯示不工作
事情是,我試圖在網絡表單中顯示更新進度。我能夠做到,但無論如何都無法隱瞞它。所以,我試圖把這個更新進程放在一個,並嘗試使用jquery隱藏div。
我在第一次加載時隱藏div有點成功。但後來如果我在下拉菜單中做了一些選擇,並再次提交數據,則更新進度不會顯示。我的意思是,在第一次加載頁面和單擊事件時,更新進度顯示並隱藏。但是,在Cascading下拉列表中進行了一些選擇後,該頁面將部分回發,並且更新進度未顯示出來再次點擊或其他。
由於除了新鮮的頁面加載,在其他情況下會發生部分回發。因此,在部分回發方案期間沒有顯示更新進度。
注: - WebForm的是母版頁的內容頁...
我在這裏張貼jQuery和守則。請看看,並糾正我在哪裏做錯了,請建議正確的事情。

可以試試'$(document).on(「click」,'#btnSearch',function(){'而不是'$('#btnSearch')。click(function(){' – vijayP
