ASP Webforms JQuery

本文关键字：JQuery Webforms ASP | 更新日期: 2023-09-27 18:03:24

我正在使用VS 2015并开始一个新的asp.net c# Webforms项目。模板包括ScriptManager。问题是我不能得到JQuery的内容页工作。工作良好的独立页面。请参考我的代码。

谢谢,

母版页代码

下面是我的内容页的代码-代码不工作。我只能参考jquery在我的主页和内容页，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>

ASP Webforms JQuery

仅在母版页中声明jQuery主文件就足够了。继承母版页的内容页自动获取这些jquery文件。不需要在两个页面都声明。

添加MasterPageFile属性:

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

和你的内容:

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

请删除内容中的此代码:

<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>

你不应该输入jquery js lib超过一次。你已经把它放在母版页了，所以，不需要再把它放在内容页。

然后要获得组件id，你应该使用ClientId，即:

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

也许像这样:

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