update field or redirect page using jquery and asp.net mvc

Im new to jquery and stuck with what i want to achieve. Heres what I want to do using jquery and asp.net mvc.

• click a submit button
• this calls an action method called LogOn in the controller Account
• if the call allows users to log in succesfully redirect to a url (sepecified by LogOn)
• if it fails replace a div(with id="error") with "sorry error occured"

so far I tried this:

 $("#submit"开发者_运维百科)
            .button()
            .click(function () {
                $.ajax({
                    type: "POST",
                    url: "Account/LogOn",
                    dataType: "json",
                    success: function (data, textStatus) {
                        if (data.redirect) {
                            // data.redirect contains the string URL to redirect to
                            window.location.href = data.redirect;
                        }
                        else {
                            // data.form contains the HTML for the replacement form
                            $("#error2").replaceWith(data.error);
                        }
                    }
                });

            });

how do I construct the relevant bits in the action method? to make this work? and is the jquery code ok? i suspect prob not.

Thanks

If you want to redirect asp.net page at same directory , you can by Jquery/Java script by this :

  $("#ctl00_iframecontent_BtnCancle").click(function () {
        window.location = "IncSLAList.aspx?bi=37";
    });

and To redirect to Another page of project , can use :

     window.location.href = "http://ImageUpload/Welcome.aspx?

Your jQuery is almost correct:

• Don't call .button() (unless you're using jQuery UI and want to do that)
• Add return false; at the end of the click handler to prevent the browser from submitting normally.

In the action, you would either return Json(new { redirect = str }) or return Json(new { error = str }).
