Jquery Firefox won't submit form

I was attempting submit a cart checkout page to a hosted order form. I was submitting the form via a jquery call after modifying the form by removing some un-necessary elements and modifying the form action. This worked fine in IE/Chrome but not FF. In FF the form was not submitted. It was apparently due to the removing of the extra elements. I found this post that helped me out:

I was using ASP.NET button as using the submit behavior. I removed the asp.net button and replace it with a plain old html input button and it worked great!

Here is some sample code:

Input Button:

<input type="button" name="btnPayment" value="Checkout" onclick="update();" id="btnPayment">


Javascript:

function update() {

if ($("#uType").val() == "US") {

$("#__EVENTVALIDATION").remove();

$("#__VIEWSTATE").remove();

$("#__PREVIOUSPAGE").remove();

$("#__EVENTARGUMENT").remove();

$("#__EVENTTARGET").remove();

$elements = $('input[id^="ctl00_SubContentPlaceHolder_"]').remove();

$('form').get(0).action = "https://xxx.com/payment";

$('form').get(0).submit();

}

}

Hope that helps!!!
