如何从ruby-on-rails (HTML)调用函数？

<button onclick="myFunction()">点击调用函数</button>

<script>
function myFunction() {
  // 在这里编写要执行的函数代码
}
</script>

<button id="myButton">点击调用函数</button>

<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script>
$(document).ready(function() {
  $("#myButton").click(function() {
    $.ajax({
      url: "/path/to/server/function",
      type: "POST",
      data: {param1: "value1", param2: "value2"},
      success: function(response) {
        // 在这里处理服务器端函数的响应
      }
    });
  });
});
</script>

<form action="/path/to/server/function" method="POST">
  <input type="text" name="param1" value="value1">
  <input type="text" name="param2" value="value2">
  <input type="submit" value="提交">
</form>
