我认为你应该尝试一些 AJAX 调用：

$('#divExternalPage').on('click', 'input[type="submit"]', function(e){
   e.preventDefault();
   $.get('http://mywebsite/ExternalPage.aspx', function(data) {
     console.log(data); // this would show you the returned data.
   });
});

• 在浏览器的控制台中，您可以看到从 AJAX 请求返回的响应。*

由于内容是动态的，因此必须将事件委托给最近的静态父对象，在本例中是#divExternalPage，或者可以直接将事件委托给$(document) or $(document.body)。

更新！我正在CodeProject.com上更新下面的代码。请搜索“将ASPX页面加载到另一个页面”。

我也在尝试做类似的事情：尝试将一个ASPX页面的内容加载到一个HTML页面中，并在提交一些东西时使用ASPX页面的代码。也许下面的代码可以帮助你。注意，我只是一个JQuery初学者！如果有人可以改进下面的代码...请做！

你可以使用iframe标签和绑定**. aspx**页面很容易。它很容易使用。

var acc = document.getElementsByClassName("accordion");
var i;

for (i = 0; i < acc.length; i++) {
  acc[i].onclick = function() {
    this.classList.toggle("active");
    var panel = this.nextElementSibling;
    if (panel.style.maxHeight){
      panel.style.maxHeight = null;
    } else {
      panel.style.maxHeight = panel.scrollHeight + "px";
    } 
  }
}

button.accordion {
    background-color: #eee;
    color: #444;
    cursor: pointer;
    padding: 18px;
    width: 100%;
    border: none;
    text-align: left;
    outline: none;
    font-size: 15px;
    transition: 0.4s;
}

button.accordion.active, button.accordion:hover {
    background-color: #ddd;
}

div.panel {
    padding: 0 18px;
    background-color: white;
    max-height: 0;
    overflow: hidden;
    transition: max-height 0.2s ease-out;
}
