HTML with XML using jQuery

本文关键字：jQuery using XML with HTML 更新时间：2023-09-26

我有包含大量数据的XML文件。现在我想选择一个有条件的价格。我在 JavaScript 函数中设置了一个参数，但它没有给出期望的结果。我认为这可以通过子节点完成，但我不知道这一点

XML 文件

<head>
  <script type="text/javascript">
    function myXml(origin, destination ) {
      var x = xmlDoc.getElementsByTagName("flights");
      for(i=0; i<x.length; i++) {
          if (x[i].getAttribute('FrTLAs') == origin
           && x[i].getAttribute('destination') == destination) {
              alert(x[i].getAttribute('price'))
          }
      }
    }
  </script>
</head>
<body>
  <a href="#" onclick="myXml('SYD','Bali')">click me</a>
</body>

你错过了吗？？

xmlDoc=loadXMLDoc("flights.xml");

示例 2 非常清楚如何使用它

x=xmlDoc.getElementsByTagName("book")[0].attributes;
   //here its would be getElementsByTagName("flights") in the loop
   //then .attributes on it
   // and then this
frtlas=x.getNamedItem("FrTLAs");
desti=x.getNamedItem("destination");
//and your code here

希望这有帮助
