Calling a web service from javascript and .net 2.0

Question

Thank you all for your help, fishing rod.

Hello everybody,

Is it possible to call a web service (on my localhost) from jquery on a simple HTML page inside an asp.net 2.0 web application using visual studio 2005?

<script type="text/javascript">
    $(document).ready(function(){
        $('#button1').click(function(){                
            $('#targetDiv').load('http://localhost/testservice/Service1.asmx/HelloWorld',null,function(){alert('test')});
        });
    });
</script>

Am I having a 500 error? Not sure if this is possible to do so?

thanks, core

By default, ASP.Net does not include web methods for queries GET(this is what it .load()does without data ). Scott Guthrie has a good blog post on how to incorporate GET into web methods .

, - ( ), $.post() :

$('#button1').click(function(){                
  $.post('http://localhost/testservice/Service1.asmx/HelloWorld',
    function(data) { $('#targetDiv').html(data); }
  );
});

.load() POST , :

$('#button1').click(function(){                
  $('#targetDiv')
    .load('http://localhost/testservice/Service1.asmx/HelloWorld', {});
});

{} - , .load() POST GET.

A 500 error means your web service made an exception. Check the event log to see what the problem is, or debug the web service to find out.
