This is used to call the Web Service using ASP.Net and Script Manager. Must be inserted in .aspx page.
<asp:ScriptManager runat=”server” ID=”scriptManager”> <Services> <asp:ServiceReference path=”WebService/TestService.asmx” /> </Services> </asp:ScriptManager>This is the script to call the web service method and print the result on the form:
<script type=”text/javascript”>var res1=0;
var res2=0;
LoadById(2);
function initialize() { document.getElementById(“javaControls”).className=””;
document.write(res1);
document.write(res2);
}
function OnSucceed(result) {
res1=result[0];res2=result[1];
initialize();
}
function LoadById(id) {
TestService.GetResult(id, OnSucceed);
}
function LoadByDetail(testId) {
TestService.GetResultByDetail(testId, OnSucceed);
}
</script>
