Things to note when JQuyer $.post and $.ajax access WCF ajax service_jquery

复制代码 代码如下:

$.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, rnError message is:" $(jqXHR.responseText).text();
window.alert(msg);
}
});

$.ajax:

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.

以上都是按个人理解所写，有不对之处请指正
