如何绕过表单动作？

Question

I am trying to bypass my form action="WFMSWI.aspx" , my form is working perfectly on my system but when i am testing on server the form comes through a proprietary software which provides database and inputs the form action automatically, which i not allowing my C# code to trigger. I tried using J query ajax but in URL it cannot the method because they change the URL too, if I put anything action like action="#" they change it no matter what.What can do to bypass it and that my method triggers instead of it. i also tried using Handler but nothing is working. Everything is working perfectly in local system and in server too it doesn't show any error it just fires form action rather than my c# code.

Form Action:

<form action="WFMSWI.aspx" id="form1" runat="server"  method="post" name="form1">

Form Button:

<input type="button" ID="submit"  class="btn btn-success" value="Approve" />                
<button id="hiddenButton" runat="server" onserverclick="btnClick_Click" style="display:none;" ></button>

Java Script :

<script type="text/javascript">

    var isEmpty = function (element) {
        if ($("#" + element).val() == "" || $("#" + element).val() == null) {
            return true;
        } else {
            return false;
        }

    };

    var arrayCheck = function (array) {
        for (var i = 0; i < array.length; i++) {
            if (array[i] == false) {
                return false;
            }

        };

        return true;
    };

    function arrayAssign(array, num) {
        for (var i = 0; i < num; i++) {
            array[i] = false;

        };

        return array;
    };



    function validationCheck(array, number, element) {
        if (isEmpty(element)) {
            $("#" + element).parent(".form-group").addClass("has-error");
            array[number] = false;
        } else {
            $("#" + element).parent(".form-group").removeClass("has-error");
