To get the value just use this    lt select id   ari select  onchange    getvalue    gt   lt option value    1  gt  lt  option gt   lt option value    2  gt  lt  option gt   lt option value    3  gt  lt  option gt   lt option value    4  gt  lt  option gt   lt  select gt    lt script gt  function getvalue         alert     ari select option selected   val         lt  script gt    this will fetch the values
