PAGEMETHODS is not working from JS function

Question

I am trying to call code behind method from JS function using pagemethods but its not calling and its not throwing any error either...

function example(){

pagemethods.method();
}

**aspx.cs
[webmethod]
public static void method(){

//some logic
}

so to find the issue i did some negative testing for that

1. I commented WEBMETHOD then it showed an error by saying"object does not support this property or method".can i assume this case shows pagemethods is working!!!

2. Then I replaced calling method name in JS function to pagemethods.newmethod() but i didn't change method name to newmethod..i was expecting an some error but it didn't give me an error..

NOTE:i have "method=post" in form declaration..does it effect pagemethods anything..

so confused why this issue is happening!!!

can we call codebehind method in any other way instead of pagemethods..please advice!!!

Solution

in msnd you can see a sample of this, so you need...

in markup:

<asp:ScriptManager ID="sm" runat="server" EnablePageMethods="true">
    <Scripts >
        <asp:ScriptReference Path="pm.js" />
    </Scripts>
</asp:ScriptManager>

in code behind: your static method, with attribute [WebMethod]

in pm.js: something like this

function example(){
    PageMethods.method();
}

UPDATE
Another variant is use an ajax request to your method, for example with jquery in goes like this:

function CallMethod(){
    $.ajax({
        type: "POST",
        dataType: 'json',
        contentType: "application/json; charset=utf-8",
        url: "YourPage.aspx/yourmathod",
        data:JSON.stringify({}), // parameters for method
        success: function (dt) { alert(dt);}, //all Ok
        error: function () { alert('error'); } // some error
    });
}
