2.jQuery程式碼

window.onload = function () {
      //get解析xml文件
      $.get("1.xml", function (data) {
        $data = $(data);
        //獲得節(jié)點(diǎn)
        var $books = $data.find("book");
        var $names = $data.find("name");
        var $authors = $data.find("author");
        //var $authors = $data.find("author") = $books.children("author") = $names.siblings("author");//獲得books的子節(jié)點(diǎn)
        //獲得屬性、節(jié)點(diǎn)text
        //var id = $($books[0]).attr("id") = $books[0].getAttribute("id");//獲得第一個(gè)book的id屬性
        $authors.each(function () {
          var author_text = $(this).text(); //獲得節(jié)點(diǎn)內(nèi)部文本,嘗試過用nodeValue無果(不兼容)
        })
