我使用'clouddns'模块将~800个域名导入Rackspace帐户.我一直收到错误说下面的内容

TypeError: Cannot call method 'forEach' of undefined
at _wrapDomains (/home/duet/www/git/node-rackspace/node_modules/clouddns/lib/clouddns/core.js:146:17)

在查看有问题的库文件(core.js)后,我决定在那里抛出一些日志语句,看看我是否能弄清楚发生了什么.这是代码:

CloudDNS.prototype.getDomains = function getDomains(options, callback) {
    var args = Array.prototype.slice.call(arguments),
        callback = args[args.length - 1];

    if (typeof callback !== 'function') {
        throw new Error("This method requires a callback");
    }

    var self = this;
    var reqOpts = {
        method: 'GET',
        uri: this.dnsUrl('domains'),
        client: this …

我正在尝试使用需要调用的API来获取具有基本HTTP身份验证的Json.我用javascript并不精彩.

我的代码是:

    <script type="text/javascript">

    $.getJSON({
        'url': 'http://data.unistats.ac.uk/api/KIS/Institutions.JSON?pageIndex=1&pageSize=25',
        'beforeSend': function(xhr) {
            xhr.setRequestHeader("Authorization",
                "Basic " + encodeBase64("ABCDEF" + ":" + password));
        },
        success: function(result) {
            alert('done');
        },
        error: function(result) {
            alert('no');
        }
    });
    </script>

我希望这可以称之为成功或错误之一.因此输出应该是警告说"完成"或警告说"不".甚至是开发人员控制台中的错误告诉我出了什么问题.

我没有得到任何东西,也没有警报显示,我在控制台中没有错误.有什么想法在这里发生了什么？

谢谢,

编辑:使用firebug我看到请求标题是:请求标题显示为:

Host: data.unistats.ac.uk

这似乎不正确,因为它应该是:授权:基本TheSecurityKey

响应是405,方法不允许重新加载页面以获取源代码:http://data.unistats.ac.uk/api/KIS/Institutions.JSON？pageIndex = 1&pageSize = 25

响应标头:

我想在段落标记的clok上添加select类.我写了代码,但它没有用.请建议.

代码如下:

<style type="text/css">
    #elm p { background:#FF0000; color:#FFFFFF; font-weight:bold;}
    .select{ background:#000099;}

</style>
<script type="text/javascript" src="js/jquery-1.10.2.min.js"></script>
<script type="text/javascript">

$(document).ready(function(){
    $('#elm').click( function(){ $("p").addClass('hover') });
    function(){ $("p").removeClass('hover') }
});
});

</script>
