bootstrap, JQuery 加载函数;无法从外部 html 文档加载元素

bootstrap, JQuery load function; cannot load elements from an external html document

我拼命地尝试遵循有关使用 JQuery 从外部页面加载 html 元素的基本教程。

我有一个名为 oltest.html 的 html 文档,其中仅包含:

<ol id="projects">
<li>un</li>
<li>deux</li>
<li>trois</li>
</ol>

和一个 html 文档,test.html,在第一个加载 ol 元素的旁边:

<!DOCTYPE html>
<html lang="fr">
  <head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <!-- The above 3 meta tags *must* come first in the head; any other head content must come *after* these tags -->
    <meta name="description" content="Test">
    <meta name="author" content="">
    <link rel="icon" href="favicon.ico">

    <title>Test</title>

    <!-- Bootstrap core CSS -->
    <link href="css/bootstrap.min.css" rel="stylesheet">

    <!-- Custom styles for this template -->
    <link href="home.css" rel="stylesheet">

    <!-- Just for debugging purposes. Don't actually copy these 2 lines! -->
    <!--[if lt IE 9]><script src="../../assets/js/ie8-responsive-file-warning.js"></script><![endif]-->
    <!--script src="../../assets/js/ie-emulation-modes-warning.js"></script-->

    <!-- HTML5 shim and Respond.js for IE8 support of HTML5 elements and media queries -->
    <!--[if lt IE 9]>
      <script src="https://oss.maxcdn.com/html5shiv/3.7.2/html5shiv.min.js"></script>
      <script src="https://oss.maxcdn.com/respond/1.4.2/respond.min.js"></script>
    <![endif]-->
  </head>

  <body>
    <div>   
    <!--ol id="projects">
    <li>un</li>
    <li>deux</li>
    <li>trois</li>
    </ol-->


    <ol id="new-projects"></ol>

    </div> <!-- /container -->


    <!-- Bootstrap core JavaScript
    ================================================== -->
    <!-- Placed at the end of the document so the pages load faster -->
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
    <script src="js/bootstrap.min.js"></script>
    <script>
        $( "#new-projects" ).load( "oltest.html #projects li" );
    </script>
    <!-- IE10 viewport hack for Surface/desktop Windows 8 bug -->
    <!--script src="../../assets/js/ie10-viewport-bug-workaround.js"></script-->
  </body>
</html>

但这不起作用。有人知道吗?提前致谢。

这是一个有趣的问题。它可能没有加载外部 HTML 文件,因为 运行 您的测试是在本地进行的。当我在本地 运行 你的代码时,我得到了这个控制台错误:

XMLHttpRequest cannot load file:///path/to/your/html/file. Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https, chrome-extension-resource.

您可能想看看这个 Whosebug 线程:

希望对您有所帮助!
