jquery - IE 8 JQuery .find() 不适用于 XML 字符串

Question

JQuery 似乎无法在返回的 XML 字符串中找到我的选择器字符串。它似乎可以在 Chrome 中运行，但由于浏览器身份验证问题，我无法在同一环境中进行调试。

我知道过去曾有人问过此类问题，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<z:row这里最重要的是:

以下例程旨在迭代此响应并查找关联值。它完全无法执行，就好像 xData.XML 为空一样(我也尝试了 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);
    });

Here is a link to a screenshot of my IE8 debugger窗口有几 block watch 。 xData.xml字符串被突出显示。该断点紧接在我上面的迭代例程之前。

• 我的选择器格式是否不正确？
• 我的选择器需要额外的转义吗？
• 我是否看到了错误的返回值或对象？

我绝对在这里拔掉我的头发。我在 Chrome 中将选择器更改为“行”并且它有效；在 IE8 中这没有什么区别。

此外，请查看 this blog post查看一个工作示例。最初我使用“xData.responseXML”，但它在调试器中显示为“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。现代浏览器倾向于允许它并使用"new"html 元素，而旧浏览器(IE6、7、8)则对它们感到窒息。

尝试使用

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