html - Is it possible to overwrite the action-value in a form? -

is possible overwrite action-value of 1 searchfield when submitting value of second searchfield? i'm in need of adding searchfield

      <input type="search" id="id2">       <input type="submit" value="value2" />

to:

  <form method="get" action="/../.." id="search">     <div>       <input type="search" id="id1">       <input type="submit" value="value1" />   </div>   </form>

by pressing enter in second searchfield, i'm forwarded link of first searchfield because has action-value.

can change behaviour?

using javascript :

    function setaction(){          document.getelementbyid('search').setattribute('action',document.getelementbyid('id2').value     } 

you need set onclick event of 'id2' setaction().
