var local = 'http://localhost:1163/CustomerService.svc/getcustomer?method=?';
var dev = 'http://yourserver.com/CustomerService.svc/GetCustomer?method=?';
$.getJSON(dev, function (customer) {
alert(customer.Address);
alert(customer.Name);
});
如果我在远程域上运行http://yourserver.com/CustomerService.svc/getcustomer?method=foo'，则会出现访问被拒绝错误；如果我运行http://yourserver.com/CustomerService.svc/getcustomer?method=?'，则会出现此错误(请参见下文)，并且您的样本中的内容完全相同页.似乎"method = foo"拒绝访问"和"method =?"抛出此错误:URI:
if i run http://yourserver.com/CustomerService.svc/getcustomer?method=foo' on the remote domain i get access denied error AND if i run http://yourserver.com/CustomerService.svc/getcustomer?method=?' i get this error(see below) and i have exactly what you have in your sample page. it seems that "method=foo" "get access denied" and "method=?" throw this error: URI:
"http://yourserver.com/CustomerService.svc.svc/GetCustomer?method=jsonp1290197214042"

UPDATE2
我已经在两种不同的情况下进行了测试:
i have tested with two different scenario:
1)可以与本地主机正常工作
$.getJSON('http://localhost:1163/service.svc/getcustomer?method=?', function (customer) {
alert(customer.Address);
alert(customer.Name);
});
2)不适用于跨域
$.getJSON('http://yourserver.com/CustomerService.svc/getcustomer?method=?', function (customer) {
alert(customer.Address);
alert(customer.Name);
});
我收到此错误:
消息:应为';' 行数:1 字符:11 代码:0
Message: Expected ';' Line: 1 Char: 11 Code: 0
URI: http://yourserver.com/CustomerService.svc/GetCustomer?method=jsonp1290183992345
UPDATE2
UPDATE1
当我在浏览器中运行服务时 http://yourserver.com/CustomerService.svc/getcustomer 我得到一个弹出窗口，要求我进行细化或保存文件，因此我将文件保存到浏览器中，然后在记事本中打开它，然后看到数据，因此将其返回给我jsonp.
when i run the service in the browser http://yourserver.com/CustomerService.svc/getcustomer i get the the popup window asking for me to fine or save the file, so i save the file to browser and i open it in the notepad and i see that the data so its returning me the jsonp.
{"Address":"1 Example Way","Name":"Bob"}
您到底要我在按钮的哪个位置放置return false?
where exactly you want me to put return false in the button?
在调试器上，我只是为了插入代码而已.
on the debugger i put just for steping in the code.
UPDATE1
更新: 以下是我如何致电我的跨域服务.
UPDATE: below is how i am calling to my cross domain service.
$(document).ready(function () {
$("#driver").click(function (event) {
$.getJSON('http://yourserver.com/CustomerService.svc/getcustomer?method=?', function (customer) {
debugger
alert(customer.Address);
alert(customer.Name);
});
});
});

更新结束
我一直在fx3.5上使用WCF学习和构建JSONP Web服务.我终于在此文章和MSDN文章带有填充的JSON(AJAX)
I've been learning and building JSONP Web services using WCF on fx3.5. I finally got a sample togather with the help of this article and MSDN article JSON with Padding (AJAX)
我正在本地运行
http://localhost:4058/WiringJsonImpl.svc
进行测试.
它没有显示标准的wsdl屏幕，而是显示消息当前已禁用此服务的元数据发布"
instead of getting the standard wsdl screen it display the message "Metadata publishing for this service is currently disabled"
我将地址粘贴到网址中
http://yourserver.com/LocationService.svc/GetLocation?method=jsonpCallback
然后按Enter键，我将在IE浏览器中看到带有此消息的黑屏.
and hit enter i see the blank screen with this message in IE browser.
The webpage cannot be found
HTTP 400
在我的web.conig中，我看到错误，但没有停止运行该应用程序:
in my web.conig i see the error but does not stop running the application:
<bindings>
<customBinding>
<binding name="jsonpBinding">
<jsonpMessageEncoding/> //<<<error here
<httpTransport manualAddressing="true"/>
</binding>
</customBinding>
</bindings>
推荐答案
在提供的示例应用程序(JSONP)中，服务方法称为GetCustomer，而不是GetLocation.这么称呼:
In the provided sample application (JSONP) the service method is called GetCustomer and not GetLocation. So to call it:
http://localhost:1163/service.svc/getcustomer?method=jsoncallback
在我的浏览器中返回了以下响应:
which returned the following response in my browser:
jsoncallback( {"Address":"1 Example Way","Name":"Bob"} );
Visual Studio Intellisense强调<jsonpMessageEncoding/>的原因是因为这是一个自定义绑定元素，而不是架构的一部分，并且未知.您可以放心地忽略此警告.
The reason that Visual Studio Intellisense underlines the <jsonpMessageEncoding/> is because this is a custom binding element and not part of the schema and it is not known. You can safely ignore this warning.
此示例的唯一问题是文件打包在类库中，而不是Web应用程序中.为了在Visual Studio内置服务器中更轻松地运行服务，您可以创建一个新的Web应用程序，将所有文件复制到该新应用程序中并运行它.您只需要在web.config中修改此行:
The only problem with this sample is that the files are packaged in a Class Library instead of Web Application. In order to run the service more easily in the Visual Studio built in server you could create a new Web Application, copy all the files to this new application and run it. You just need to modify this line in web.config:
<add name="jsonpMessageEncoding"
type="Microsoft.Ajax.Samples.JsonpBindingExtension, service, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"/>
^
包括您的Web应用程序名称:
to include your web application name:
<add name="jsonpMessageEncoding"
type="Microsoft.Ajax.Samples.JsonpBindingExtension, MyWebAppName, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"/>
^
仅此而已.现在，继续编写使用此JSONP流的客户端应用程序. jQuery在 $.getJSON() 方法中做得很好:
That's all. Now go ahead and write a client application which consumes this JSONP stream. jquery does a great job with the $.getJSON() method:
$.getJSON('http://localhost:1163/service.svc/getcustomer?method=?', function(customer) {
alert(customer.Address);
});
我已经在这里上传了工作版本.
