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);
}
});
