You can make an AJAX request like any other requests:
您可以像任何其他请求一样发出 AJAX 请求:
$.ajax( {
type:'Get',
url:'http://mysite.com/mywebservice',
success:function(data) {
alert(data);
}
})

EDIT:
编辑:
The OP was not looking to use cross-domain requests, but jQuery supports JSONP as of v1.5. See jQuery.ajax(), specificically the crossDomain
parameter.
OP 并不打算使用跨域请求,但 jQuery 从 v1.5 开始支持 JSONP。请参阅jQuery.ajax(),特别是crossDomain
参数。
The regular jQuery Ajax requests will not work cross-site, so if you want to query a remote RESTful web service, you'll probably have to make a proxy on your server and query that with a jQuery get request. See this sitefor an example.
常规的 jQuery Ajax 请求无法跨站点工作,因此如果您想查询远程 RESTful Web 服务,您可能必须在服务器上创建一个代理并使用 jQuery get 请求进行查询。有关示例,请参阅此站点。
If it's a SOAP web service, you may want to try the jqSOAPClient plugin.
如果它是 SOAP Web 服务,您可能想尝试jqSOAPClient 插件。

The post shows how to create a service proxy straight up in javascript.

Incase people have a problem like myself following Marwan Aouida's answer ... the code has a small typo. Instead of "success" it says "sucess" change the spelling and the code works fine.
如果按照 Marwan Aouida 的回答,人们有像我这样的问题......代码有一个小错字。而不是“成功”,它说“成功”改变拼写,代码工作正常。

In Java, this return value fails with jQuery Ajax GET:
在 Java 中,此返回值会因 jQuery Ajax GET 而失败:
return Response.status(200).entity(pojoObj).build();
But this works:
但这有效:
ResponseBuilder rb = Response.status(200).entity(pojoObj);
return rb.header("Access-Control-Allow-Origin", "*").build();
----
Full class:
全班:
@Path("/password")
public class PasswordStorage {
@GET
@Produces({ MediaType.APPLICATION_JSON })
public Response getRole() {
Contact pojoObj= new Contact();
pojoObj.setRole("manager");
ResponseBuilder rb = Response.status(200).entity(pojoObj);
return rb.header("Access-Control-Allow-Origin", "*").build();
//Fails jQuery: return Response.status(200).entity(pojoObj).build();
}
}
