Question

I’ve developed a web service in asp.net and am able to test it from an in-project aspx page and can readily display the information that was returned in JSON format.

I now need to consume the web service from a stand-alone html page.

Does someone have experience with this? I’m puzzled by the part that would replace this

<asp:ScriptManager ID='ScriptManager' runat='server'>     <Services>         <asp:ServiceReference Path='~\MyService.asmx' />     </Services> </asp:ScriptManager> 

If this is not possible with straight html and javascript, can someone show me a stand-alone php page that would do it?

See this link:

Use JQuery

Essentially, you make your Web Service script callable, just an attribute in your Web Service definition and you do:

  $.ajax({     type: 'POST',     url: '~/MyService.asmx/MyMethod',     data: '{parameterName:'' aStringArgument + ''}',     contentType: 'application/json; charset=utf-8',     dataType: 'json',     success: function(msg) {        var data = msg.d        // Now var is an object with properties just like your object     }   });
