Javascript 表单未通过ajax发送到php页面

我创建了一个表单，其中包含输入，我试图通过ajax调用将其发送到php表单，以便获取电子邮件

通过查看我的“网络”选项卡，我没有看到我的php文件

email project.php

显示，除非我查找的位置错误。我不确定我做错了什么。我得到的唯一错误是ajax变量中此行的意外标记：

var项目名称=$（“#项目名称”）.val（）

有人知道怎么回事吗

<form action="" autocomplete="on" method="POST" id="project-information-form">
    <input type="text" class="input-borderless" id="project-name" placeholder="Your Name">
    <input type="text" class="input-borderless" id="title-roll" placeholder="Title/Role">
    <input type="email" class="input-borderless" id="project-email" placeholder="Email Address">
    <input type="text" class="input-borderless" id="project-number" placeholder="Phone Number">

</div>
<div class="project-input-container2">
    <textarea rows="3" class="input-borderless" id="project-description" placeholder="Describe the project"></textarea>
    <input type="text" class="input-borderless" id="project-source" placeholder="How did you hear about us?">
    <input type="text" class="input-borderless" id="project-socialMedia" placeholder="Which of our social media influenced you the most?">
    <input type="text" class="input-borderless" id="project-humanTest" placeholder="Human Test: What day comess after Thursday?">

    <input type="submit" id="submit-project" value="Send Project Inquiry">

JS教程101：变量名只能包含字母、数字和下划线。
表单提交，页面重定向。您需要使用
event.preventDefault（）
或
返回false停止该操作。在控制台中查看抛出的错误…事件在所有浏览器中都不是全局的，需要将as参数添加到事件处理程序中。还可以通过在元素上使用名称和
serialize（）
极大地简化要发送的数据收集。表单控件上应始终有名称
$（“#提交项目”）。在（“单击”上，函数（事件）.
