Question

我在网上看过一些例子，但我仍然在努力解决这个问题。我想在“ indexDesc ”标记中获取“ descShort ”标记的值，然后显示“最后”中的值“ 标签？我见过人们使用箭头＆gt;但我还是迷路了。

Answer 1

“＆gt;”是一个选择器;您可以在此处查看所有可用的内容：selectors。 “div＆gt; span”将找到所有具有div作为父母的跨度。这与“div span”不同，它将找到所有跨越div的后代。

var values = [];

$(yourXml).find('index').each(function () {
  var self = $(this);

  values.push({
    descShort: self.find('descShort:first').text(),
    capitalLast: self.children('capital').children('last').text(),
    grossLast: self.children('gross').children('last').text()
  });
});

values现在是一个对象数组，每个对象都有descShort，captialLast和grossLast属性。

不幸的是我无法测试我的代码。
