I’m calling a Pagemethod in a Javascript function, but it goes straight to the end not entering my function C#. Follow the code below:

<script type="text/javascript">
    function enviar() {
        if (document.getElementById('<% =CPF.ClientID %>').value == "") {
            alert("Informe o documento do devedor!");
            document.getElementById('<% =CPF.ClientID %>').focus();
            return false;
        }

        PageMethods.VerificaCaixa(cartID, onSucess);

        function onSucess(result) {
            if (result != "") {
                str = result.split("|||");
                if (trim(str[0]) != "A") {
                    alert("Caixa fechado, favor abra o caixa e repita a operação!");
                    location.href = "/Caixa/Abrir/frmAbrCaixa.aspx";
                }
            }
        }
    }
</script>


<form name="frm" runat="server">
    <asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="True">
    </asp:ScriptManager>
    <table width="95%" border="0" align="center">
        <tr>
            <td class="tblNormal" align="right">CPF/CNPJ:</td>
            <td class="tblNormal" valign="middle" align="left">
                <asp:TextBox ID="CPF" runat="server" onblur='return valida();' MaxLength="14" Width="130px">
            </td>
        </tr>
        <tr>
            <td class="tblNormal" colspan="2" align="center">
                <asp:Button ID="btnEnviar" runat="server" Text="Enviar" CssClass="btn btn-default" OnClick="btnEnviar_Click" OnClientClick="enviar();" />
            </td>
        </tr>
    </table>
</form>

    {
        CPesquisa pesquisa = new CPesquisa();

        string parametros = "";
        parametros = pesquisa.VerificaCaixa(cart);

  • add the code of your methods and what error you are having, so we will be able to help you :)

  • Even if I create the code with a deliberate error to try to simulate your mistake, my code will be different than yours. Post your code friend so we can view.

On the page of MSDN you get an example.

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

Your method has to contain [WebMethod] to be exposed. In the archive myPageMethods.js, you would do something like this.

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

In case of any problem, you can consume your method via ajax too.

function method(){
    $.ajax({
        type: "POST",
        dataType: 'json',
        contentType: "application/json; charset=utf-8",
        url: "myPage.aspx/metodo",
        data:JSON.stringify({}), // parametros de entrada do metodo
        success: function (dt) { alert(dt);}, //sucesso
        error: function () { alert('error'); } // error
    });
}
