Question

我有一个页面，它将XMLHttpRequest调用到另一个站点的页面。问题是，返回的状态是0。来电者页面的代码：

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>HTML Template</title>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
<meta name="Generator" content="Dev-PHP 2.6.0" />
<meta name="Keywords" content="your,keywords,here" />
<meta name="Description" content="." />

</head>
<body>
<p>
  <input type="text" name="txtReturn" id="txtReturn" size=75 />
</p>

<textarea name="taStatus" id="taStatus" cols="75" rows="25"></textarea>

<p>&nbsp; </p>
<script type="text/javascript">
function getReturn()
{
    var txtBox = document.getElementById("txtReturn");
    var taStatus = document.getElementById("taStatus");

    txtBox.value = "Preparing to get Response";

    if (window.XMLHttpRequest)
    {// code for IE7+, Firefox, Chrome, Opera, Safari
        // alert('IE7+, Firefox, Chrome, Opera, Safari');
        xmlhttp=new XMLHttpRequest();
    }
    else
    {// code for IE6, IE5
        // alert('IE6, IE5');
        xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
    }

    xmlhttp.onreadystatechange=function()
    {   
        taStatus.innerHTML = taStatus.innerHTML + "URL: " + url + ".\nReadyStatus: " + xmlhttp.readyState + ".\nStatus: " + xmlhttp.status + ".\nStatusText: " + xmlhttp.statusText + ".\nresponseText: " + xmlhttp.responseText + ".\n\n";

        if (xmlhttp.readyState==4 && xmlhttp.status==200)
        {
                // alert(xmlhttp.responseText);
            txtBox.value = xmlhttp.responseText;
                // alert(xmlhttp.responseText);
        }

    }

    var url = 'http://www.ip.com.om/site/checkdata.php';
    var url2 = 'http://badihbarakat.com/site/checkdata.php';
    var url3 = '../site/checkdata.php';

    xmlhttp.withCredentials = true;
    // url = url + ((/\?/).test(url) ? "&" : "?") + (new Date()).getTime();
    xmlhttp.open("GET", url, true);
    xmlhttp.send();

}

    getReturn();
</script>
</body>
</html>

另一个网站上的.php页面，只是回显一个带有日期和时间的字符串。

任何人都可以建议可能出现的问题吗？我正在使用FireFox 27，我已经检查了错误浏览器，它显示：

**GET http://www.ip.com.om/site/checkdata.php [HTTP/1.1 200 OK 710ms]**

当您点击它时，请求的详细信息显示：

由于安全问题，您无法对其他域中的服务器执行xmlhttp请求。您可以从服务器端代码使用服务，然后可以通过您自己的服务将其代理到页面。查看以下帖子。 Still confused about using XMLHTTPRequest cross domain
