javascript - .parseHTML()替代jQuery 1.7？

我有一个ajax函数可以从RSS提要中加载图像，但是由于我仍在使用1.7.2，所以得到了一个.parseHTML is not a function error。不幸的是，不能升级到1.8。

$.ajax({
    type: "GET",
    url: "url.com/feed",
    dataType: "xml",
    success: function(xml) {
        var limit = 1;
        $(xml).find('item').each(function(index) {
            if (index < limit) {
                var title = $(this).find('title').text();
                var url = $(this).find('link').text();
                var pubDate = $(this).find('pubDate').text();
                var desc = $(this).find('description').text();
                desc = $.parseHTML(desc);
                var imgURL = desc[0].firstChild.srcset.split(',').pop().trim().split(' ')[0];
                var alt = desc[0].firstChild.alt;
                // Do something
                return;
            }
        }); //end each
    }
});

我正在使用.praseHTML()定位图像的最后一个srcset属性以获取其URL。这是我的RSS的样子

最佳答案

您实际上在这里不需要jQuery。 Ajax中的X首先代表XML。

https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/responseXML

使用responseXML属性获取文档，则可以在其上使用经典的DOM方法（例如element.querySelector）。
