JQuery 似乎无法在返回的 XML 字符串中找到我的选择器字符串。它似乎在 Chrome 中工作，但由于浏览器身份验证问题，我无法在同一环境中调试。

我知道过去曾有人问过这类问题，但我没有找到任何特别适用于我的情况的问题。

以下 XML 响应由 SOAP 请求提供；我相信这<z:row件作品在这里很重要：

以下例程旨在遍历此响应并找到关联的值。它完全无法执行，好像 xData.XML 是空的（我也尝试过 xData.xml - 没有变化）。

$(xData.XML).find("z\\:row").each(function() {
           quantityOneArray[i] = parseFloat($(this).attr("ows_Quantity"));
           quantityTwoArray[i] = parseFloat($(this).attr("ows_Quantity2"));
           i++;
           alert("xData "+ i + ": "+xData.XML);
    });

这是我的 IE8 调试器窗口屏幕截图的链接，其中包含几个手表。xData.xml字符串突出显示。这个断点紧接在我上面的迭代例程之前。

  • 我的选择器格式不正确吗？
  • 我的选择器是否需要额外的转义？
  • 我是否在查看错误的返回值或对象？

我绝对在这里拔头发。我在 Chrome 中将选择器更改为“行”，它可以工作；在 IE8 中没有区别。

另外，请查看此博客文章以查看工作示例。最初我使用的是“xData.responseXML”，但它会在调试器中显示为“未定义”。

看起来您正在将 xml 字符串传递给$()，这将导致 jQuery 将该 xml 字符串转换为 HTML。现代浏览器倾向于只允许它并使用“新” html 元素，而旧浏览器（IE6、7、8）会扼杀它们。

尝试使用

var xmlDoc = $.parseXML(xData.XML);
$(xmlDoc).find("z\\:row").each(...

试试这个，

铬/火狐：

xml.children[0].childNodes[1].innerHTML

IE8+/Safari：

xml.childNodes[0].childNodes[1].textContent

IE8：

xml.documentElement.childNodes[1].text；

示例代码在这里，

var xml = $.parseXML(XMLDOC);

var xmlNodeValue = "";

if(userAgent.match("msie 8.0")){

xmlNodeValue = xml.children[0].childNodes[1].innerHTML;

}else{ // IE8+

xmlNodeValue = xml.childNodes[0].childNodes[1].textContent;

}
