Question

我在这里使用jQuery供稿脚本http://camagu.github.io/jquery-feeds/demos/：下面是一个带有jquery的工作html页面，它从html列表中的链接列表中提取到RSS源的链接，并将它们传递给feeds函数，该函数在页面上的div中显示它们。

我的问题是我想动态创建网址数组，以便从页面上的内容传递给feed函数（listoflinks）（我已经完成了），但不是一次传递一个listoflinks [ 0]，我想在listoflinks中传递整个数组。如何修改它以使用任意数量的链接而不是指定的数组大小，我知道我应该做一个foreach循环，但不知道它应该放在哪里才能工作。目前，每个链接都通过$ listoflinks [0]，$ listoflinks [1]，$ listoflinks [2]等传递给feed函数。

我建议你创建一个空对象

var listoflinks = {};

然后替换此行

$(".field-name-field-news ul li a").each(function() { listoflinks.push("http:" + $(this).attr("href")) });

使用以下内容向对象添加项目

    $(".field-name-field-news ul li a").each(function(index) { 
      listoflinks['option'+index] = "http:" + $(this).attr("href"); 
   });

现在，不要将4个项目传递给feed（）方法，而是传递我们之前构建的对象

$('.feed').feeds( {
   feeds: listoflinks, 
  // your function (didn't modify this)
  preprocess: function(feed) {}
 });
