我有一个本地运行的网络应用程序，我想使用 jquery 从此 url 获取特定的 div，而不加载完整的页面。有一个部分包含用于打开模式对话框的按钮。我浏览了一些在这里找到的例子，但无法解决我的问题。下面是页面
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="css/modal.css" />
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.0/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.0/js/bootstrap.min.js"></script>
<script src="https://code.jquery.com/jquery-1.9.1.min.js"></script>
<script>
$(document).ready(function(){
$.post("https://localhost:44330/",{},function(response){
$(response).find('testblock').each(function(){
$('#main').append($(this).html());
});
});
});
</script>
</head>
<body>
<div class="text-center">
<h1 class="display-4">Hello from sub application 2</h1>
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal1">Open</button>
<!-- Modal -->
<div class="modal fade" id="myModal1" role="dialog">
<div class="modal-dialog modal-lg" style="height: 100%; width: 100%">
<!-- Modal content-->
<div class="modal-content" style="height: 90%; width: 100%">
<div class="modal-body" id="main">
@*<iframe src="https://localhost:44330/" width="1200" height="700" style="overflow: hidden; height: 90%; width: 100%; border: 1px solid red;" scrolling="yes"></iframe>*@
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
</div>
<script src="js/modalClick.js"></script>
</body>
</html>
URL 具有以下结构
<html>
<head>
<script type="text/javascript" src="jquery.js"></script>
</head>
<body>
<div id ="testblock">
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal5">Open modal</button>
<!-- Modal -->
<div class="modal fade" id="myModal5" role="dialog">
<div class="modal-dialog modal-lg" style="height: 100%">
<!-- Modal content-->
<div class="modal-content" style="height: 90%">
<div class="modal-body" style="height: 90%">
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal" id="myBtn5">Close</button>
</div>
</div>
</div>
</div>
</div>
</body>
</html>
我试过this示例但不起作用
最佳答案
您忘记添加# 。您将 testblock 定义为 ID。 <div id="testblock"> ...
$(response).find('#testblock') ...
