jQuery：输入类型的文本值显示在警报中

Question

  function ValidateLogin() { alert($("#txtUserName").val()); //alert($('#txtUserName').val()); }

 <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Login | Profi Admin</title> <link href="css/960.css" rel="stylesheet" type="text/css" media="all" /> <link href="css/reset.css" rel="stylesheet" type="text/css" media="all" /> <link href="css/text.css" rel="stylesheet" type="text/css" media="all" /> <link href="css/login.css" rel="stylesheet" type="text/css" media="all" /> </head> <body> <div class="container_16"> <div class="grid_6 prefix_5 suffix_5"> <h1>Login</h1> <div id="login"> @* <p class="tip">You just need to hit the button and you're in!</p> <p class="error">This is when something is wrong!</p>*@ <form id="form1" name="form1" method="post" action=""> <p> <label> <strong>Username</strong> <input type="text" name="UserName" class="inputText" id="txtUserName" /> </label> </p> <p> <label> <strong>Password</strong> <input type="password" name="Password" class="inputText" id="txtPassword" /> </label> </p> <a class="black_button" onclick="return ValidateLogin();"><span>Authentification</span></a> <label> <input type="checkbox" name="checkbox" id="checkbox" />Remember me</label> </form> <br clear="all" /> </div> <div id="forgot"> <a href="#" class="forgotlink"><span>Forgot your username or password?</span></a> </div> </div> </div> <br clear="all" /> </body> </html>

Here, in the alert, I am not getting the UserName. 在这里，在警报中，我没有得到用户名。 I also tried using single quotes, still it's not showing up. 我也尝试使用单引号，但仍然没有出现。

Maybe you forgot to Enable Jquery in your site, Because in the example below it works perfect. 也许您忘记了在站点中启用Jquery，因为在下面的示例中它可以完美地工作。

 function ValidateLogin() { alert($("#txtUserName").val()); //alert($('#txtUserName').val()); }

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="container_16"> <div class="grid_6 prefix_5 suffix_5"> <h1>Login</h1> <div id="login"> <form id="form1" name="form1" method="post" action=""> <p> <label> <strong>Username</strong> <input type="text" name="UserName" class="inputText" id="txtUserName" /> </label> </p> <p> <label> <strong>Password</strong> <input type="password" name="Password" class="inputText" id="txtPassword" /> </label> </p> <a class="black_button" onclick="return ValidateLogin();"><span>Authentification</span></a> <label> <input type="checkbox" name="checkbox" id="checkbox" /> Remember me</label> </form> <br clear="all" /> </div> <div id="forgot"> <a href="#" class="forgotlink"><span>Forgot your username or password?</span></a> </div> </div> </div> <br clear="all" />
