I am fetching css from ajax and in onsuccess function my code is as follow:
我正在从 ajax 获取 css，在 onsuccess 函数中，我的代码如下：
$(xml).find('item').each(function() {
var title = $(this).find('title').eq(0).text();
var url = $(this).find('content').attr('url');
// Printing url as undefined
alert(url);
console.log($(this).find('content');
});
What I want to get content url attribute I am getting item children (title, description, content, commentRss and comments) but when I try to get $(this).find('content') It is not giving me anything Can anyone figure it out what am I doing wrong? Thanks
