假设以下是我们的按钮 −

<button id="submitForm">Submit</button>

根据按钮 ID，在表单提交时生成警报 −

$("#submitForm").click(function() {
   alert("The Form has been Submitted.");
});

示例

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initialscale=1.0">
<title>Document</title>
<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
</head>
<body>
CollegeId=<input id="collegeId" type="text"><br />
CollegeName= <input id="collegeName" type="text"><br />
<button id="submitForm">Submit</button>
<script>
   $("#submitForm").click(function() {
      alert("The Form has been Submitted.");
   });
</script>
</body>
</html>

要运行上述程序，请将文件名保存为"anyName.html(index.html)"，然后右键单击该文件。在 VS Code 编辑器中选择选项"使用 Live Server 打开"。
