Question

我正在创建一个函数来获取xml文件并对其进行编辑。我之前从未做过，所以我搜索了一种获取xml文件的好方法。我决定使用ajax，但由于未定义url，因此从未返回文件。

编辑：我编辑了代码，并在成功函数中进行了处理。现在此文件没有问题。这是ajax部分的更新：

$.ajax({
    type: 'GET',
    url: 'allrtp.xml',
    dataType: 'xml',
    success: function(xml) {
        //file = $.parseXML(xml);

        // Editing the file to have the good dates
        $(xml).find('StartDateTime').text(start);
        $(xml).find('EndDateTime').text(end);

        var strFile;

        if (window.ActiveXObject) {
            strFile = xml.xml;
        } else {
            strFile = (new XMLSerializer()).serializeToString(xml);
        }

        var encoded64 = Base64.encode(strFile); // Encoded in base64
        var encodeURL = encodeURIComponent(encoded64); // Encoded URL

        var AR = urlAR + encodeURL; // The URL to open
        window.open(AR, '_blank');
    }
})

现在，关于xml文件的一切工作都很好，我的window.open有一个小问题，它打开了我的网址，但开头是％31，但这是另一个问题。

谢谢您的帮助！

Answer 1

添加错误回调：错误：函数（例如）{}

许多事情都可能发生，您将通过错误回调获得更多信息。可能是您查询的网址不正确。不要相信未定义的url，请参阅返回您的jquery ajax函数的内容。也许您应该查询“ \ files \ xxx.xml”之类的东西。

Answer 2

文件未定义，因为您在ajax成功函数中声明了文件
