我正在使用 jquery 构建我的网站的 RSS 提要,并且链接元素一直返回空白。我自己构建的 javascript 解决方案没有问题,但 jquery 似乎讨厌链接元素。
下面是jquery代码:
function loadData(xml, ifid) {
var htmlStr;
var iframeToWrite = document.getElementById(ifid);
htmlStr = "<html><body>"
var items = $(xml).find("channel item").each(function () {
var $article = $(this);
var title = $article.find("title").text();
var description = $article.find("description").text();
var link = $article.find("link").text();
var pubDate = $article.find("pubDate").text();
htmlStr += "<div class='Rssitem'>\n";
htmlStr += "\t<h3><a href='" + link + "' target='_blank' >" +
title + "</a></h3>\n";
htmlStr += "\t<p>" + description + "</p>\n";
htmlStr += "\t<h6>" + pubDate + "</h6>\n";
htmlStr += "</div>\n"
});
htmlStr += "</body></hmtl>";
iframeToWrite.contentDocument.write(htmlStr);
}
下面是我从得到的 npr 流中编辑的示例 xml:
