JQuyer $.post 与 $.ajax 访问WCF ajax service 时的问题需要注意的地方

$.post('<%=this.AppPath %>DataService/InventoryUIService.svc/Rename', ///location.protocol + "//" + location.host + location.pathname + "/Rename", 
odata, 
function (result) { 
$dialogProcessing.dialog("close"); 
if (result.Success) { 
alert("Success"); 
} 
else { 
var msg = "Your submit fauiler, Detail message is:" + result.ErrorMessage; 
window.alert(msg); 
} 
}, 
"json"); 
$.ajax({ 
url: '<%=this.AppPath %>DataService/InventoryUIService.svc/Rename', 
type: 'POST', 
contentType: 'application/json', 
dataType: 'json', 
data: odata, 
success: function (result) { 
if (result.Success) { 
alert("Success"); 
} 
else { 
var msg = "Your submit fauiler, Detail message is:" + result.ErrorMessage; 
window.alert(msg); 
} 
}, 
error: function (jqXHR, textStatus, errorThrown) { 
var msg = "Your submit throw a error, \r\nError message is:" + $(jqXHR.responseText).text(); 
window.alert(msg); 
} 
});

感觉$.post是用来提交forms的，而要跟wcf ajax service访问，还必须得用$.ajax来指定Content-Type.

后来找到的资料: http://stackoverflow.com/questions/2845459/jquery-how-to-make-post-use-contenttype-application-json

以上都是按个人理解所写，有不对之处请指正
