使用jQuery从XML获取嵌套项目 [英] Get nested item from XML with jQuery

问题描述

我已经在网上查看了一些示例，但是我仍在为此而苦苦挣扎. 我想在" indexDesc "标签中获取" descShort "标签的值，然后在"最后一个"中显示该值"标签?我见过人们使用箭头>，但我仍然迷路.

I've looked at some examples on the web but I am still struggling with this. I would like to get the value for "descShort" tag within the "indexDesc" tag and then after that display the value from the "last" tag? I've seen people using the arrow > but I'm still lost.

推荐答案

>"是选择器；您可以在此处查看所有可用的选项:选择器. "div> span"将找到所有以div为父对象的span.这与"div span"不同，"div span"将找到所有属于div的后代.

The ">" is a selector; you can see all f the available ones here: selectors. "div > span" will find all spans that have div's as parents. This is different to "div span", which will find all spans which are descendents of divs.

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，每个对象具有descShort，captialLast和GrossLast属性.

values is now an array of objects, each with descShort, captialLast and grossLast properties.

不幸的是，我无法测试我的代码.

Unfortunately I can't test my code.
