所以我有一个字符串，类似于Wed, 08 May 2013 11:11:30 GMT. （仅供参考，它是从 XML RSS 文件中提取的）我想要从上面的字符串到两个变量，Wed, 08 May和11:11. 据我所知，这里需要做几件事：

  • 删去第三个空格前的文字
  • 剪掉第 4 个空格和第 2 个冒号之间的文本
  • 将这两段文本保存为变量

除此之外，我不知道该怎么做。任何人都可以帮忙吗？到目前为止，我的代码如下：

$.ajax({
            type: 'GET',
            url: 'proxy.php',
            data: {requrl: "http://feeds.bbci.co.uk/news/rss.xml"},
            dataType: 'xml',
            success: function (xml) {
                $('#newsTimeline').empty();
                $(xml).find("item").each(function () {
                    //for(var i = 0; i < $item.length && i < 5; i++){
                        var title = $(this).find("title").text();
                        var description = $(this).find("description").text();
                        var linkUrl = $(this).find("link_url").text();
                        var link = "<a href='" + linkUrl + "' target='_blank'>Read More<a>";
                        $('#feedContainer').append('
                            <li>\
                                <time class="cbp_tmtime" datetime="2013-04-10 18:30"><span>4/10/13</span> <span>18:30</span></time>\
                                <div class="cbp_tmicon cbp_tmicon-phone"></div>\
                                <div class="cbp_tmlabel">\
                                    <h2>Ricebean black-eyed pea</h2>\
                                    <p>Winter purslane courgette pumpkin quandong komatsuna fennel green bean cucumber watercress. Pea sprouts wattle seed rutabaga okra yarrow cress avocado grape radish bush tomato ricebean black-eyed pea maize eggplant. Cabbage lentil cucumber chickpea sorrel gram garbanzo plantain lotus root bok choy squash cress potato summer purslane salsify fennel horseradish dulse.

Plantain salad beetroot bunya nuts black-eyed pea collard greens radish water spinach gourd chicory prairie turnip avocado sierra leone bologi.</p>\
                                </div>\
                            </li>\
                        ');
                    //}
                });
            }
        });

如您所见，我已经删除了标题、描述并阅读了更多文本。proxy.php 文件只是一个 file_get_contents 请求。

您的问题的解决方案是：Parse RSS pubDate to Date object in JavaScript

为了也获得时间：

var pubDate = "Sun, 27 Mar 2011 20:17:21 +0100";
var date = new Date(pubDate);

var months = Array("January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December");
var string = date.getDate() + " " + months[date.getMonth()] + " " + date.getFullYear()

var time = date.getHours()+":"+date.getMinutes();

alert(string+"\n"+time);

var str1="Wed, 08 may 2013 11:11:30 GMT";
var test1 = str1.substring(0,str1.length-17);
alert(test1 );
var test2 = str1.substring(test1.length+4,str1.length-7);
alert(test2 );

检查这是完美的工作，
