IE9中的Ajax / jQuery / PHP但不是IE 8或更低版本

My jQuery/AJAX script posts to a php file in hopes of returning XML. When I print if the data I get all the html source code returned and the xml is not properly parsed in IE 8 or less. The code works in IE 9 and all other browsers. If anyone has a suggesion to what is goin on or a solution to my problem?

我的jQuery / AJAX脚本发布到php文件，希望返回XML。当我打印如果数据我得到所有html源代码返回并且xml未在IE 8或更低版本中正确解析。该代码适用于IE 9和所有其他浏览器。如果有人对我的问题有什么建议或解决我的问题？

jQuery:

jQuery的：

$.post("load-content/", {type: "POST", img: placeholder, dataType: "XML", selection: $(this).html()}, function(xml)  {
                // format and output result
                // alert(placeholder+' && '+$(this).html());
                nshow = $("content", xml).text() ;
                $("div p.p2").html(
                    $("content", xml).text() 
                );
                alert("HERE IE 9+ "+xml.length);
            });

php:

PHP：

if(isset($_REQUEST["img"]) && isset($_REQUEST["selection"])) {
      $xml='<ratings><content>test</content></ratings>';
      echo $xml;

Solved.
There were two problems here.

解决了。这里有两个问题。

As the above answer suggested there was a problem with headers.
如上面的答案所示，标题存在问题。
Again as the answer above suggested there was a problem with the datatype... code for older IE browsers should look something like

再次如上面的答案所示，数据类型存在问题...较旧的IE浏览器的代码应该类似于
```
$.post("/load-content/", {type: "POST", img: showcase, menuv: aname}, function(response) { ...
```

Actually i think your problem is making the ajax call itself. You are using $.post but youre supplying the options hash as if it is $.ajax. The two are different...

实际上我认为你的问题是自己调用ajax。您正在使用$ .post但是您提供的选项哈希就好像它是$ .ajax一样。两者不同......

$.post takes the url, data, callback and response type as the arguments. You are supplying a hash similar to the one you would supply to $.ajax as your second argument which is not what it wants.

$ .post将url，data，callback和response类型作为参数。您提供的哈希类似于您将提供给$ .ajax的哈希值作为您的第二个参数，而不是它想要的。

If you are going to use $.post it shoudl look like this:

如果你打算使用$ .post，它应该是这样的：

$.post("load-content/", {img: placeholder, selction: whatever}, function(), 'xml');

Additionally its not obivous what the contex of your call is... this may not exist unless this is inside an event handler or jQuery.each iteration so using selection: $(this).html() may not make sense.

此外，你的调用的上下文不是很明显...这可能不存在，除非这是在事件处理程序或jQuery.each迭代中，所以使用选择：$（this）.html（）可能没有意义。

Have you tried setting the proper header for your response and exiting immeadiately?

您是否尝试过为响应设置正确的标题并立即退出？

 if(isset($_REQUEST["img"]) && isset($_REQUEST["selection"])) {
      header('Content-type: application/xml');
      $xml='<ratings><content>test</content></ratings>';
      echo $xml;
      exit(0);
 }
