Error with jquery in ie8

I get this error:

Webpage error details

User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET4.0C; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729) Timestamp: Tue, 26 Jun 2012 11:31:22 UTC

Message: Object doesn't support this property or method Line: 56 Char: 738 Code: 0

I cant rely on that ie debugger , cause when i view source, i see line 56 as a long line, and i dont know where the error really is? is there a way to trace the error? what does the error doesnt support.Here is line 56:

function send_email(to) {
    if (to.length == 0) {
        $("#email_loader").html("<p>Please enter an `email address</p>");
        $("#email_response").fadeIn(250);
    }
    else {
        _gaq.push(['_trackEvent', 'Email', FA.appID]);
        $("#email_loader").html("<img src='http://apps.com/img/ajax_load.gif' />");
        $("#email_response").fadeIn(500);
        $.get("/inc_appdl_main_api.php", {
            to: to,
            app_id: FA.appID
        }, function (data) {
            if (data.length > 0) {
                $("#email_loader").html(data);
                $("#email_response").delay(1000).fadeOut(500);
            }
        });
        setTimeout(FA.iframeClose, 2000);
    }
};
function iframeClose() {
    parent.postMessage("closeFA", "*");
};
$("#to").keypress(function (event) {
    if ((event.which == '13') && ($(this).val().length > 0)) {
        to = $(this).val();
        event.preventDefault();
        send_email(to);
    }
});
$("#email").click(function () {
    to = $("#to").val();
    send_email(to);
});
function set_url_target(url) {

}

is there a way to debug in ie8?

I looked in notepad++. it points to there: char 791 to=$("#to").attr('value');send_email(to);

whats wrong with it

This worked for me:

IE threw an error because of the "to" variable. I changed this:

$("#email").click(function () {
    to = $("#to").val();
    send_email(to);
});

To this:

$("#email").click(function () {
   var to = $("#to").val();
    send_email(to);
});

IE stopped throwing the error!!

Make sure the console/developer tools is open when you load the page, or else it will fail when you try to use console.log.

Assuming that's not the problem, try liberally adding console.log() statements around the various function calls, like so:

$("#email").click(function () {
    console.log('call 1...');
    to = $("#to").val();
    console.log('call 1 done.');
    send_email(to);
});

Go crazy with it, and hopefully you'll see something in the console like 

LOG: call 7...

with no matching LOG: call 7 done.. Then you know who the culprit is.

The error mentions a couple character numbers, and those land you close to two of the .val() calls. So focus on those first. Just replace them with a constant.
