javascript - How to separate two forms in a page -

-

i have 2 forms in page when click on 1 button other form runs , >>>two windows of same page<<< open. how can separate function of these 2 or more forms in page?

the code below. form has same code different web addresses.

<form method="post">              <input id="element 1_1" class="element radio1" name="element 1" type="radio" value="http://www.yahoo.com" />      model 13<br/>     <br/>     <input id="element 2_1" class="element radio1" name="element 1" type="radio" value="http://www.msn.com" />     model 17<br/><br/>     <input id="element 3_1" class="element radio1" name="element 1" type="radio"   value="http://www.ebay.com" />      model 22 <br/><br/>  <script> $(function () {     $("form").submit(function (e) {         e.preventdefault();         var url = $(this).find('input[type="radio"]:checked').val();         window.open(url);      }); }); </script></form>

other coder

<form method="post">               <input id="element 1_2" class="element radio" name="element 2" type="radio" value="http://www.123.com" />      model 5 - 8<br/>     <br/>     <input id="element 2_2" class="element radio" name="element 2" type="radio" value="http://www.543.com" />     model 6-10<br/>     <br/> <script> $(function () {     $("form").submit(function (e) {         e.preventdefault();         var url = $(this).find('input[type="radio"]:checked').val();         window.open(url);      }); }); </script></form>

you can use attribute id each form.

<form method="post" id="form1">    ... </form>  <form method="post" id="form2">    ... </form>  <script> $(function () {   $("#form1").submit(function(e) {     // function form1   });   $("#form2").submit(function(e) {     // function form2   }); }); </script>
