$.ajax 或 $.get 函数 get 仅在本地文件上接收
我需要使用 $.ajax 或 $.get 从 xml 文件获取获取响应。 问题是 $.ajax 或 $.get 函数似乎没有从远程服务器中的文件获得响应。它显然仅适用于本地文件。我正在从本地服务器开发网站，所以我的服务器主机类似于 127.0.0.1/。有人知道这个问题吗？或者我是否可以调试这个问题？我想我读过浏览器不允许跨站点 ajax 调用的地方..但是..那么我如何进行远程主机调用？
<script>
$(document).ready(function(){
$.ajax({
url: "<?=$request_url?>",
data: "<?=$data?>",
success: function(msg){
alert( "Data Saved: " + msg );
},
error: function(XMLHttpRequest, textStatus, errorThrown) {
$("#output").append(XMLHttpRequest.responseText + "<br />TextStatus: " + textStatus + "<br />ErrorThrown: " + errorThrown);
}
})
});
</script>
I need to use $.ajax or $.get to get fetch response from xml file.
The thing is that $.ajax or $.get function does not seem to get a response from files that are in remote server. It apparently works on local files only. I am developing the websites from local server, so my serverhost is like 127.0.0.1/. Does anyone know about this problem? Or is there anyway that I can debug this problem at all? I think I have read somewhere where browsers do not allow cross-site-ajax call..but..then how can I make remote host call?
<script>
$(document).ready(function(){
$.ajax({
url: "<?=$request_url?>",
data: "<?=$data?>",
success: function(msg){
alert( "Data Saved: " + msg );
},
error: function(XMLHttpRequest, textStatus, errorThrown) {
$("#output").append(XMLHttpRequest.responseText + "<br />TextStatus: " + textStatus + "<br />ErrorThrown: " + errorThrown);
}
})
});
</script>

幸运的是，由于跨域策略，您不能这样做。不过，您可以通过
$.ajax调用来调用服务器端脚本，该调用又调用远程站点脚本。Fortunately, you cannot due to the cross-domain policy. You can however invoke a server side script via your
$.ajaxcall which in turn calls on the remote site script.看看如何使用 JSONP

是的，这是正确的，因为您无法使用这些方法访问另一个域上的内容。这是一个跨域脚本安全问题。
看一下与 jQuery 和 Javascript 相关的 XSS。
Yes, this is correct because you can't access content on another domain using those methods. This is a cross domain scripting security issue.

由于安全限制，浏览器不允许跨域 ajax 调用，
但是仍然有一些解决方法。
尝试这些

Browsers don't allow cross-domain ajax calls due to security restrictions
But there are still some workarounds in the wild.
