javascript - How can I capture form options on submit? -


how can capture form options on submit?

i have plain html form can call javascript function on exit, how capture chosen option <select> element?

please see code below:

 <legend>administration:</legend> <script type="text/javascript">   function handleit(m){       alert("hello");       }  </script> </head> <body>   <form action="javascript:handleit(select.name)"/>   <select name="num" required>   <option value="1">add anouncment</option>   <option value="2">del anouncment</option>   <option value="3">aprove </option>   <option value="4">unaprove </option>   </select>  <input name="anouncement" type="text" required>    <input name="submit"  type="submit" value="update"/> </form>

first of all, there errors in html syntax.

this data when 'submit' button pressed (jsfiddle):

$('#submit_btn').on('click', function(e) {     e.preventdefault();   console.log($('[name="num"]').val()); });  <form id="main-form" method="get">   <select name="num" required>   <option value="1">add anouncment</option>   <option value="2">del anouncment</option>   <option value="3">aprove </option>   <option value="4">unaprove </option>   </select>    <input name="anouncement" type="text" required>    <input name="submit"  type="button" value="update" id="submit_btn"/> </form>
