ASP Webforms JQuery

我使用VS 2015並開始一個新的ASP C＃Webforms項目。該模板包含ScriptManager。問題是我無法讓JQuery在內容頁面上工作。適用於獨立頁面。請參閱我的代碼。ASP Webforms JQuery

感謝，

主網頁代碼

下面是我的內容網頁的代碼 - 代碼不起作用。我但裁判在我的兩個母版和內容頁面的jQuery，不工作

<%@ Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="WebForm2.aspx.cs" Inherits="PayrollTimeManagement.WebForm2" %>  

<asp:Content ID="Content1" ContentPlaceHolderID="MainContent" runat="server">  

    <script src="Scripts/jquery-ui-1.12.0/external/jquery/jquery.js"></script> 
    <script src="Scripts/jquery-ui-1.12.0/jquery-ui.js"></script> 
    <script src="Scripts/jquery-ui-1.12.0/jquery-ui.min.js"></script> 

    <script src="Scripts/select2.js"></script> 
    <link href="Content/css/select2.css" rel="stylesheet" />  

    <script type="text/javascript"> 
     $(document).ready(function() { $("#DropDownList1").select2(); }); 
</script> 

    <asp:DropDownList ID="DropDownList1" runat="server"> 
     <asp:ListItem>aawe3wrw4t34t</asp:ListItem> 
     <asp:ListItem>ss</asp:ListItem> 
     <asp:ListItem>ff</asp:ListItem> 
     <asp:ListItem></asp:ListItem> 
     <asp:ListItem></asp:ListItem> 
     <asp:ListItem>rye</asp:ListItem> 
     <asp:ListItem></asp:ListItem> 
     <asp:ListItem>43t5</asp:ListItem> 
     <asp:ListItem></asp:ListItem> 
     <asp:ListItem>rey</asp:ListItem> 
     <asp:ListItem></asp:ListItem> 
     <asp:ListItem></asp:ListItem> 
     </asp:DropDownList> 

</asp:Content>

您的內容頁面在哪裏？爲什麼不使用ContentPlaceholder和MasterPageFile？ – toha

添加的MasterPageFile屬性：

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm3.aspx.cs" Inherits="PayrollTimeManagement.WebForm3" MasterPageFile="~/Master/Site.master" %>

和內容：

<asp:Content ID="Content1" ContentPlaceHolderID="MainContent" Runat="Server"> 
</asp:Content>

請刪除此代碼在您的內容：

<script src="Scripts/jquery-ui-1.12.0/external/jquery/jquery.js"></script> 
<script src="Scripts/jquery-ui-1.12.0/jquery-ui.js"></script> 
<script src="Scripts/jquery-ui-1.12.0/jquery-ui.min.js"></script>

你不應該多次輸入jquery js lib .. 你已經把它放在母版頁上，所以不需要再把它放在內容頁面上。

然後讓組件id，你應該使用客戶端Id即：

document.getElementById('<%=DropDownList1.ClientID%>').value

也許是這樣的：

$(document).ready(function() { 
    $("#<%=DropDownList1.ClientID %>").select2(); 
});

我粘貼了錯誤的代碼，請查看我內容頁面中的代碼 – user6741701

請檢查我的答案.. – toha

這足以單獨申報母版頁的主要jQuery的文件。繼承母版頁的內容頁自動獲取這些jquery文件。不需要在這兩個頁面中聲明。
