jQuery ajax post to web service
提问by Jan Johansen
$(document).ready(function() {
$.ajax({ type: "POST",
url: "/getprojects.ashx",
data: "<formData client=\"\" year=\"\" categories=\"\" tags=\"\" freeText=\"\" count=\"34\" page=\"1\"></formData>",
dataType: "text/xml",
cache: false,
error: function() { alert("No data found."); },
success: function(xml) {
alert("it works");
alert($(xml).find("project")[0].attr("id"));
}
});
});
My problem is i get some data back but i can't seem to get it displayed.
我的问题是我取回了一些数据，但似乎无法显示。

dataTypeshould be the type of what you receive but contentTypeshould be the mime-type of what you are sending, the following should be ok:
dataType应该是您收到的类型，但contentType应该是您发送的内容的 mime 类型，以下应该没问题：
$(document).ready(function() {
$.ajax({ type: "POST",
url: "/getprojects.ashx",
data: "<formData client=\"\" year=\"\" categories=\"\" tags=\"\" freeText=\"\" count=\"34\" page=\"1\"></formData>",
contentType: "text/xml",
dataType: "xml",
cache: false,
error: function() { alert("No data found."); },
success: function(xml) {
alert("it works");
alert($(xml).find("project")[0].attr("id"));
}
});
});

Your dataTypeseems to be wrong. It should look like
你的dataType好像错了。它应该看起来像
dataType: "xml"
Your datastructure also looks pretty wierd. Have a look at .serializeArray(). It should be standard query string foo=bar&test=blaetc.
你的data结构看起来也很奇怪。看看.serializeArray()。它应该是标准查询字符串foo=bar&test=bla等。
If the success handlergets executed, try to lookup your xmlvariable plain, without
operating on it with .find()or whatever. Still empty?
如果success handler被执行，请尝试查找您的xml变量plain，而不要对其进行操作.find()或其他任何操作。还是空的？
