jquery - 无法获取类似 XML 的字符串来在 Jquery 中解析

Question

我有一个像这样的字符串:

<note><url>urlofpage1</url><notes>These are the Notes of Page 1</notes></note>
<note><url>urlofpage2</url><notes>These are the Notes of Page 2</notes></note>

我一直在尝试解析它，以便我可以根据 URL 获取注释:

所以

notesofpage1 = getNotes('urlofpage1')

这是我尝试过的一件事，但由于某种原因不起作用。

var xml = '<note><url>urlofpage1</url><notes>These notes should load!</notes></note><note><url>urlofpage2</url><notes>These are the Notes of Page 2</notes></note>';
var $xml = $(xml);

var $notes = $xml.find('url')
                 .filter(function() { return $(this).text() == 'urlofpage1' })
                 .closest('notes');

你知道我做错了什么吗？

Answer 1

function getNotes(urltext) {
    var notes;
    var xmlString = "<note><url>urlofpage1</url><notes>These notes should load!</notes></note><note><url>urlofpage2</url><notes>These are the Notes of Page 2</notes></note>";

    $(xmlString).find('url').each(function() {
        if ($(this).text() == urltext) {
        notes = $(this).next("notes").text();
        }
    });

   return notes;
}

var notesofpage1 = getNotes('urlofpage1');
var notesofpage2 = getNotes('urlofpage2');

alert("page 1: " + notesofpage1 + " page 2: " + notesofpage2);
