这就是我的代码的样子,它总是在Safari和Firefox中引发错误。疯狂的是,如果我删除事件侦听器,并将响应类型更改为responseText
,Internet Explorer会给我输出。我试过overrideMimetype
,但这似乎没有帮助。如果我在Firefox或Safari中检查响应,我会得到null
。我很茫然,任何帮助都会受到赞赏。
我应该提一下,我宁愿避免使用任何第三方库。
更新:
在progress
事件期间发生错误,如果我检查.lengthComputable
,我会false
更新2: Safari在这个问题上有了更多的启示:
XMLHttpRequest cannot load Origin is not allowed by Access-Control-Allow-Origin.

我不能百分百肯定,但在我看来,这个问题涉及跨站点沟通。我最终做的是让PHP脚本下载文件,然后我使用javascript在本地获取它。
<?php
$mark = $_GET['mark'];
$xmldoc = new DOMDocument();
$xmldoc -> preserveWhiteSpace = false;
$xmldoc -> formatOutput = true;
$xmldoc -> load($mark);
unlink('fenced.xml');
echo $xmldoc -> save('fenced.xml');
?>
使用Javascript:
localreq.open('GET', 'fenced.xml', true);
localreq.addEventListener('load', function(e) {xmldoc = localreq.responseXML;}, false);
localreq.send();
