javascript - 使用 Javascript 解析 XML 对象数组中的数据

Question

我的 XML 对象如下所示。我想知道如何查看它并获取开始日期和结束日期数据。稍后我想比较相同日期的约会并将其分组在一起。我擅长 JSON，但不知道如何操作 XML。我正在努力

$(xmlData).find("appointment")[0]['startdate']
$(xmlData).find("appointment")[0].find('startdate')  

<appointment>
    <appointmentid>2015032303585487505373377</appointmentid>
    <startdate>20150323000000</startdate>
    <enddate>20150323080000</enddate>

Answer 1

您需要使用 :eq() 在给定索引处获取约会。 $(xmlData).find("appointment")[0] 将给出一个不是 jQuery 对象的元素引用，因此 .find() 将给出错误

$(xmlData).find("appointment:eq(0) startdate").text()
