我在updatepanel內部使用下拉菜單,問題在於頁面刷新時從我的下拉列表中選擇值。最初更新面板工作正常,直到我添加到asp:scriptmanager的ScripPath。將ScriptPath添加到<asp:scriptmanager刷新頁面。如何阻止頁面刷新?
即使現在,如果我從scriptmanager中刪除ScriptPath,頁面不會刷新並且行爲如預期。
我添加ScriptPath的原因是,我希望每次在下拉列表中更改值時執行abc.js。正如所料,abc.js是爲我的下拉列表中的每個選定值執行的,但我不希望頁面被刷新。
那麼,即使添加scriptpath到asp:scriptmanager後,如何停止刷新頁面?
以下是我的.aspx源碼。
<asp:ScriptManager ScriptPath="abc.js" runat="server"></asp:ScriptManager>
<asp:UpdatePanel ID="UP_Social_Ddl" runat="server">

<div class="styled-select">

分享你的js代碼,我肯定有什麼不對 – nunespascal
@nunespascal我已經在我的js文件中添加了代碼。你認爲它是因爲js文件嗎?即使我把警報('嗨')它劑量執行! – Anuya
我沒有看到任何代碼,你正在聽select的onchange事件(DropDownList) – nunespascal
