# How do you invoke a web method of web service in AJAX?

In order to use a webmethod of a webservice, we need to add the reference of webservice in the <services> section of ScriptManager. Under services you have to configure the servicepath. \
\
<asp:ScriptManager ID="ScriptManager1" runat="server"> \
<Services> \
<asp:ServiceReference Path="..\service1.asmx" /> \
</Services> \
</asp:ScriptManager> \
\
Inside JAvascript Use methods of this service directly like \
service1.methodname() \
