编码onchange事件

hello i need to load page based on the results of dropdown box. for example in my code i have value="userlog". if this selected it will load userlog.php and remove itself so that only userlog.php is being used. thanks

<select onchange="updatePage(this.value)">

            <option value="">Select a report</option>
            <option value="userlog">User Logs</option>
            <option value="actionlog">Action Logs</option>

        </select>

On change event you will get the selected options value. Using this value you can decide what you want to do.

<select id="select_page">
  <option value="">Select a report</option>
  <option value="userlog">User Logs</option>
  <option value="actionlog">Action Logs</option>
</select>

$('#select_page').change(function() {
  var $el = $(this);
  if($el.val() != '') {
    $('#page').load($el.val()+'.php');
    $el.find('option:selected').remove();
  }
});

something like this :

    $(document).ready(function() {

    $("select option ").each(function() {

        if (location.href.indexOf($(this).val()) >= 0) {
            $(this).remove();
        }

    });


    $('select').change(function() {
        var obj = $(this);

        location.href = obj.val() + ".php";


    });

});
