How to rewrite and submit form at same time

Question

There is a form that i want to submit and url rewrite at the same time. I can change url by adding onsubmit="rewrite_form(event);" option in form :

function rewrite_form(e) {    
  var form = document.forms[0];   // .getElementById("form1");
  window.location = '/search/' + form.f.value + '_' + form.t.value + '.htm/' + form.amt_from.value;            
  if (e && e.preventDefault) { e.preventDefault(); }
  return false;
}

Url changes but other values of form not posted to url generated page.

Answer 1

Just change the form's action property instead.

function rewrite_form(e) {
    var form = documen.forms[0];

    form.action = 'newurl';
    //rest of code, make sure not to call e.preventDefault(); or return false
    //because the form will not get submitted
}

Answer 2

i got the solution:

    function rewrite_form() {
//Create custom link here
----------------------------
----------------------------------
//create form submit action
var url = '/search/' +'your custom link';
document.getElementById('FormId').action = url;
document.FormId.submit();
}
