我想在点击html按钮后立即发送电子邮件。为了完成这项任务,我已经编写了以下代码
HTML code:
<button onclick="sendEmail()">Send Email</button>
<p id="mailStatus"></p>
Java脚本代码:
function sendEmail()
{
$.ajax({
url: "mail.php",
type: "POST",
success: function(response) {
if (!response) {
alert("Something went wrong. Please try again");
return;
}
var parsedJSON = eval('('+response+')');
// If there's an error, display it.
if(parsedJSON.Error) {
// Handle session timeout.
if (parsedJSON.Error == "Timeout") {
alert("Session timed out. Please login again.");
window.location.reload();
}
}
document.getElementById('mailStatus').innerHTML = "Email Sent successfully";
}
});
}
问题是,当我点击发送电子邮件按钮时,我收到一条错误消息
"Uncaught ReferenceError: $ is not defined"
有人可以帮忙吗?

由于$.ajax
是jQuery的功能,因此您需要在文件中添加jQuery。
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.0/jquery.min.js"></script>
在sendMail
函数上方添加此行。
