我想做很简单的事情,但我不是成功的。我的asp.net页面上有按钮和标签,我想在点击按钮后获取标签文本。这是我的代码:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm2.aspx.cs" Inherits="DynamicWebApplication.WebForm2" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> <script type="text/javascript"> function f() { var g = $('<%=Label1.ClientID%>').val(); // Also I tried .text() and .html() alert(g); } </script> </head> <body> <form id="form1" runat="server"> <div> <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label> <p></p> <asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="f();"/> </div> </form> </body>
解决方法
尝试这个:
var g = $('#<%=Label1.ClientID%>').val();
或这个:
var g = $('#<%=Label1.ClientID%>').html();
你错过了#
添加到头部:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
