推荐答案
您遇到了跨域策略问题，原因是AJAX(出于安全原因)不允许您从页面中获取内容不在同一域上.
You're running into a cross domain policy issue cause AJAX (for security reasons) will not let you grab content from a page that does not sit on the same domain.
要摆脱它并完成任务:
您需要一个PHP文件，您可以仅使用以下PHP行来调用grabber.php:
<?php echo file_get_contents($_GET['url']); ?>
比起您的html文件(或其他文件，就像:)
Than inside your html (or whatever file just do like:)
<!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<meta charset=utf-8 />
<title>test</title>
</head>
<body>
<div id="response"></div>
</body>
<script>
$(function(){
var contentURI= 'http://domain.com #element'; // URL TO GRAB + # of any desired element // if needed :)
$('#response').load('grabber.php?url='+ contentURI);
});
</script>
</html>
这为什么起作用?
Why does this work?
- 现在，AJAX正在向
grabber.php页面发送一个简单的GET请求，
-
grabber.php回显所需的内容
- 现在内容在您的(服务器)域中了！
- AJAX很高兴为您服务:)
- now, AJAX is sending a simple GET request to the
grabber.phppage, grabber.phpechoes the desired content- now the content is on your (server) domain!
- and AJAX is happy to serve you :)
