为什么 XMLHTTP 请求不适用于我的服务器？

Question

I've rented a server and have a website right now. But I have a problem: I want to refer Textfiles I've saved on the server and load the content into a String. I've tried the following:

 <script type="text/javascript"> var filePath = "the link"; xmlhttp = new XMLHttpRequest(); xmlhttp.open("GET",filePath,false); xmlhttp.send(null); var fileContent = xmlhttp.responseText; var fileArray = fileContent.split('\\n') //Now do whatever you need with the array window.alert(fileArray); </script>

The problem ist: I doesn't work :-( I can load other Textfiles (eg from GitHub) but referencing Textfiles on my server constantly fails to work! The files are publically available and can be read and executed. I also tried to get the content via Java:

 import java.net.*; import java.io.*; public class URLReader { public static void main(String[] args) throws Exception { URL oracle = new URL("the link"); BufferedReader in = new BufferedReader( new InputStreamReader(oracle.openStream())); String inputLine; System.out.println(in.readLine()); while ((inputLine = in.readLine()) != null) System.out.println(inputLine); in.close(); } }

This code works fine (even for my server files). Can you help me? Why isn't it working?

It's most likely a cors issue as @Alex already assumed. You can fix this by adding the option Header always set Access-Control-Allow-Origin: "*" to your .htaccess on the server.
