如何在模态内容中调用javascript函数？

<!-- 模态框触发按钮 -->
<button type="button" data-toggle="modal" data-target="#myModal">打开模态框</button>

<!-- 模态框 -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h4 class="modal-title" id="myModalLabel">模态框标题</h4>
      </div>
      <div class="modal-body">
        <p>模态框内容</p>
        <button type="button" onclick="myFunction()">调用JavaScript函数</button>
      </div>
    </div>
  </div>
</div>

<!-- JavaScript函数 -->
<script>
function myFunction() {
  // 在这里执行你的操作
  alert("Hello, World!");
}
</script>
