I have a header.master ASP page and I am trying to handle a button click.
My MasterPage.master has the following codes:
<%@ Master Language="VB" CodeFile="MasterPage.master.vb" Inherits="MasterPage" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<asp:ContentPlaceHolder id="head" runat="server">
</asp:ContentPlaceHolder>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>
</div>
</form>
</body>
In Default.aspx page I have the following code:
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox ID="TextBox1" runat="server"/>
<asp:Button ID="Button2" text="Search" runat="server"/>
</div>
<script>
$(document).ready(function () {
//write your code here
var txt = $('input[id$=TextBox2]').val();
$("input[id$=Button2]").click(function () {
alert("Hello world!");
});
});
</script>
</form>
</body>
</html>
Everytime I click the button I get the following error: 0x800a1391 - JavaScript runtime error: '$' is undefined
My HTML source code has this:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head><title>
</title>
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
</head>
<body>
<form method="post" action="Default.aspx" id="form1">
<div class="aspNetHidden">
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="7dUu7W1yzgwgCERTGi4lbDb7UGbWC6oigS9K1dTKxNLxOKUQzVp9hkyhbKT/e5Ve22nU2D7eaALUFm2bnAuOroUPGHMRph/IDyBFloPmn0I=" />

<div>
<input name="TextBox1" type="text" id="TextBox1" />

</div>
<script>
$(document).ready(function () {
//write your code here
var txt = $('input[id$=TextBox2]').val();
$("input[id$=Button2]").click(function () {

});
});
</script>
</form>
</body>
</html>
