return xml in jquery ajax
提问by Christos Mitsis
My problem is that I want to return an xml file from server back to client and parsing it using ajax function of jquery. This is the code:
我的问题是我想将一个 xml 文件从服务器返回给客户端并使用 jquery 的 ajax 函数解析它。这是代码：
Client:
客户：
$("#submit").click(function(){
$.ajax({
type: "POST",
url: "search.php",
data: "whatever",
dataType: "xml",
async: false,
success: function(xml){
var data = $('doctor',xml).text();
alert(data);
}
});
});
Server(php file),
服务器（php文件），
header('Content-type: text/xml');
echo '<?xml version="1.0" encoding="utf-8"?>';
echo "<tables>";
echo "<doctor>Someone</doctor>";
echo "</tables>";
I have a blank alert and I do not know why??
我有一个空白警报，我不知道为什么？
好的，我找到了。我的 php 文件是这种形式
//some code
include("other.php");
//some other code
where the other.php file was the file I posted above. I cut/paste the header so the final php file would be
other.php 文件是我在上面发布的文件。我剪切/粘贴标题，因此最终的 php 文件将是
//some code
header('Content-type: text/xml');
include("other.php");
//some other code
and other.php
和其他.php
echo '<?xml version="1.0" encoding="utf-8"?>';
echo "<tables>";
echo "<doctor>Someone</doctor>";
echo "</tables>";
now it works perfect. Thanks for your quick replies!
现在它完美无缺。感谢您的快速回复！

This is working fine
这工作正常
Post.php file
Post.php 文件
if($_GET['id']!=""){
$array = array('satyam' => 'satyam',
'class' => 'B.TECH',
'company' => 'Ranosys');
}
$new ='<?xml version="1.0" encoding="iso-8859-1"?><data>';
foreach($array as $key => $values){
$new .= "<$key>$values</$key>";
}
echo $new.'</data>';
=================
function load_data(){
$.ajax({
url: "post.php",
async: false, // stop browser for another activity
data: "id=satyam",
// dataType :'xml',
error: function(e, b, error) {
for(var i in e){
// alert(i);
}
alert(e.respone);
},
success: function(msg) {
//alert($response);
var data = $(msg).find("satyam").text();
alert(data);
}
});
}

Try this: var data = $(xml).find('doctor').text()
尝试这个： var data = $(xml).find('doctor').text()
In your example, 'xml' is not a jQuery object.
在您的示例中， 'xml' 不是 jQuery 对象。

You need to parse this XML (I really don't understand why , but...), you can do it by do:
你需要解析这个 XML（我真的不明白为什么，但是......），你可以这样做：
$(xml).find('doctor').text();
Bye. :)
再见。:)

You have to change your function to be:
您必须将您的功能更改为：
$("#submit").click(function(){
$.ajax({
type: "POST",
url: "search.php",
data: "whatever",
dataType: "xml",
async: false,
success: function(xml){
var xmlDoc;
if (window.DOMParser) {
parser = new DOMParser();
xmlDoc = parser.parseFromString(xml, "text/xml");
}
else {// Internet Explorer
xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = "false";
xmlDoc.loadXML(xml);
}
var $response = $(xmlDoc);
var data = $response.find("doctor").text()
alert(data);
}
});
});
The reason for the if (window.DOMParser) {is that you'll have an issue with IE doing the parsing.
if (window.DOMParser) {的原因是您在 IE 进行解析时会遇到问题。
