With this example, you will see how you can post a form when you change a value from a drop down select element.
Jquery Code
The code below can be translated to mean the following. When the ‘myclass’ class is changed from a user selecting a different option, that form is automatically submitted.
<script type="text/javascript"> $(document).ready(function () { $('.myclass').change(function () { $(this).closest('form').trigger('submit'); }); }); </script>
HTML Select Element
WThe select element has a class called ‘myclass’ and its name attribute is my_item.
<select class="myclass" name="my_item"> <option value="all">All</option> <option value="1">One</option> <option value="2">Two</option> </select>
