<p>I'm trying to use jQuery to get data from an ASP.NET web service (SharePoint Server 2007 lists.asmx), but any call to a web service will really help as a first step in that direction.</p>

Here is an example to call your webservice using jQuery.get:
```
```
$.get("http://domain.com/webservice.asmx", { name: "John", time: "2pm" },
  function(data){
    alert("Data Loaded: " + data);
  });
```
```
In the example above, we call "webservice.asmx", passing two parameters: name and time. Then, getting the service output in the call back function.
