IE 8 JQuery .find（）不能在XML字符串上工作 [英] IE 8 JQuery .find() not working on XML string

问题描述

JQuery似乎无法在返回的XML字符串中找到我的选择器字符串。它显示为在Chrome中工作，但由于浏览器身份验证问题，我无法在相同的环境中调试。

我知道这些类型以前的问题，但我没有发现任何具体适用于我的情况。

以下XML响应是从SOAP请求提供的;我相信< z：row 是这里最重要的部分：

遍历这个响应并找到相关的值，它完全无法执行，就好像xData.XML是空的一样（我也试过xData.xml - 没有改变）。

<$ p $（$）$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $（$） .attr（ows_Quantity））;
quantityTwoArray [i] = parseFloat（$（this）.attr（ows_Quantity2））;
i ++;
alert（xData+ i +：+ xData.XML）;
}）;

下面是几个手表的链接，IE8调试器的截图窗口 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？


• 选举人需要额外的逃生？


• 我是在看错误的返回值或对象吗？
  

我绝对是在这里拉我的头发。我在Chrome中将选择器更改为row，并且工作正常;在IE8中没有区别。

另外，请看这个博客文章来看一个工作的例子。最初我使用的是xData.responseXML，但在调试器中会显示为Undefined。

解决方案

正在传递一个xml字符串给 $（），这会导致jQuery将该xml字符串转换为HTML。现代浏览器往往只是允许它，并与新的HTML元素，而旧的浏览器（IE6,7,8）呛他们。

尝试使用

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

JQuery does not seem to be able to find my selector string inside of a returned XML string. It appears to be working in Chrome, but I can't debug in the same environment due to browser authentication issues.

I know these type of questions have been asked in the past, but I haven't found anything that specifically applies to my situation.

The following XML response is supplied from a SOAP request; I believe the <z:row piece is what matters here:

The following routine is designed to iterate through this response and find associated values. It completely fails to execute as though the xData.XML is empty (I also tried xData.xml - no change).

$(xData.XML).find("z\\:row").each(function() {
           quantityOneArray[i] = parseFloat($(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 window with several watches. The xData.xml string is highlighted. This breakpoint immediately precedes my iteration routine above.

• Is my selector formatted incorrectly?
• Does my selector require additional escapes?
• Am I looking at the wrong return value or object?

I am absolutely pulling out my hair here. I changed the selector to "row" in Chrome and it works; in IE8 that makes no difference.

Also, take a look at this blog post to see a working example. Initially I was using "xData.responseXML" but it would show as "Undefined" in the debugger.

解决方案

It looks like you are passing an xml string to $(), which would result in jQuery turning that xml string into HTML. Modern browsers tend to just allow it and go with the "new" html elements, while older browsers (IE6,7,8) choke on them.

Try using

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