Why after AJAX post, the URL redirect to a URL with the POST params like GET params in this addon?

[malin]

In the [addonmodule Controller.php](https://github.com/WHMCS/sample-addon-module/blob/master/modules/addons/addonmodule/lib/Admin/Controller.php):

I append this `order_detail` function:

```
    /**
     * @param $vars
     */
    public function order_detail($vars){

        $modulelink = $vars['modulelink']; // eg. addonmodules.php?module=addonmodule
        $version = $vars['version']; // eg. 1.0
        $LANG = $vars['_lang']; // an array of the currently loaded language variables

        $orderid = 28;//isset($_REQUEST['orderid']) ? $_REQUEST['orderid'] : '';

        $sql = "SELECT tblhosting.id, tblhosting.regdate, tblhosting.domain, tblhosting.billingcycle, tblhosting.nextduedate, tblhosting.nextinvoicedate, tblhosting.termination_date, tblhosting.domainstatus, tblhosting.username, tblhosting.notes, tblhosting.dedicatedip, tblhosting.assignedips FROM tblhosting ";
//        $sql .= "LEFT JOIN tblorders ON ";
//        $sql .= "tblhosting.orderid = tblorders.id ";
        $sql .= ("WHERE tblhosting.orderid = " . $orderid);

        $tblhostings = Capsule::select($sql);

        $table_tbody = "";
        for($i = 0; $i < count($tblhostings); $i ++) {

            $item = $tblhostings[$i];

            $row = "<tr>";

            $row .= ("<td><input type='text' id='tblhosting-id' name='id' class='form-control' readonly=\"readonly\" style='width:80px;' value='" . $item->id . "'></td>");
            $row .= ("<td><textarea id='tblhosting-domain' name='domain' class='form-control' style='width:320px;'>" . $item->domain . "</textarea></td>");
            //$row .= ("<td>" . $item->billingcycle . "</td>");
            $row .= ("<td ><div style='width:80px;'>" . $item->nextduedate . "</div></td>");
            $row .= ("<td ><div style='width:80px;'>" . $item->nextinvoicedate . "</div></td>");
            //$row .= ("<td>" . $item->termination_date . "</td>");
            //$row .= ("<td>" . $item->username . "</td>");

            $row .= ("<td><textarea id='tblhosting-dedicatedip' name='dedicatedip' class='form-control' style='width:200px;'>" . $item->dedicatedip . "</textarea></td>");
            $row .= ("<td><textarea id='tblhosting-assignedips' name='assignedips' class='form-control' style='width:200px;'>" . $item->assignedips .  "</textarea></td>");
            $row .= ("<td>" . $item->domainstatus . "</td>");
            $row .= ("<td><div style='width:80px;'>" . $item->regdate . "</div></td>");
            $row .= ("<td><textarea id='tblhosting-notes' type='textarea' name='notes' class='form-control' style='width:200px;'>" . $item->notes .  "</textarea></td>");

            $row .= ("<td> <button id='modify' type='submit' class='btn btn-warning'>modify</button>  <button id='send-email' type='button' class='btn btn-success'>Send email</button>  </td>");

            $row .= "</tr>";

            $table_tbody .= $row;

        }

I want to use this way to update the `tblhosting` entries.  You see my jQuery code want to use `post` method to update the `tblhosting` entry. 

 when I click update button, it will execute the update url, but however it will redirect to this URL 

```
http://192.168.33.10/whmcs/admin/addonmodules.php?id=28&domain=10.93.240.193-194（15M%29+HK-Z7-A15++E5-2650%282CPU%29%2F32G%2F500G+ssd%2F++&dedicatedip=10.93.240.193-194&assignedips=10.93.240.193%0D%0A10.93.240.194&notes=02442%2F66655%0D%0A10&intellisearch=1&token=ac271aed87528e68969608329e8a1f4d2a35c858&value=

As we know the ajax will not refresh a whole page, and will not redirect by default after request, why there goes different? 

Who know the way to avoid the redirect?

I also tried use 
```
window.location.href(origin_url);
```
to redirect to back after the wrong redirect, but it will not execute.
