Submit drop down on click

问题:

I have a list of pages generated by Wordpress within a drop down, on click, how can submit the form and goto the page that was selected?

<form id="work" action="" method="post">
<select name="work">
    <?php $pages = get_pages(array('child_of' => '15', 'sort_column' => 'menu_order')); 
    foreach($pages as $post) {
    setup_postdata($post);
    $fields = get_fields(); ?>
        <option class="work-dropdown" value="<?php echo the_permalink(); ?>"><?php echo the_title(); ?></option>    
    <?php } wp_reset_query(); ?> 
</select>           
</form>

I tried this jquery but I'm not sure if that's correct and what to put in the action:

<script type="text/javascript">
jQuery(document).ready(function( $ ) {
$('.work-dropdown').change(function() {
  $('#work').submit();
});
});
</script>

If you simply want to redirect the page try:

<script type="text/javascript">
jQuery(document).ready(function( $ ) {
   $('select[name="work"]').change(function(){
        window.location = $(this).val();
    })
});
</script>

You may want to add an ID to the select to make the jQuery selector faster. So you would add: id="page-redirect" to the select change the jQuery object to $('#page-redirect'). ID's are selected much faster than classes or attributes.

If you want the form to post to the selected URL then try:

<script type="text/javascript">
jQuery(document).ready(function( $ ) {
    $('#work select[name="work"]').change(function(){
        $('#work').attr('action', $(this).val()).submit();
    });
});
</script>

The .change() cannot be written on option's selector as you've written. It needs to be the select. So, $('[name=work]') needs to be your selector.

Also, it looks like your link is present in the value of the option. The below code should work.

$('[name=work]').change(function() {
    window.location = $(this).val();
});

EDIT:

You cannot do submit & then redirect to the page if you're resetting the dropdown on submit. In case, you need to submit and you didn't reset the dropdown & then redirect based on the URL or index,

$('[name=work]').change(function() {
    $('#work').submit();
});
//handle it on document ready & assuming your index's first option is plain text 'Select from below'
if($('[name=menu] :selected').index() > 0)
{
    window.location = $(this).val();
}

jQuery(document).ready(function ($) {
    $('.work-dropdown').change(function () {
        $('#work').attr('action', $(this).val());
        $('#work').submit();
    });
});

Will do this
