move jQuery code to a function

I have the following jQuery code:

$('.show-additional-link').click(function(){
    $(this).parent().next().slideDown();
    $(this).hide();
    return false;
});

HTML:

<div class="row">
    <label for="native_language">Select</label>
    <select name="native_language" id="native_language">
      <option value="">Any</option>
      <option value="1">English</option>
    </select>

    <a class="show-additional-link" href="#">Select Additional Languages</a>
</div>

<div id="additional-languages" style="display: none;">      
    <div class="row">
        <!-- additional language checkboxes -->
    </div>
</div>

I would like to move the contents of my jQuery code (within the 'click' function) in to a separa开发者_如何转开发te function, as I will need to call it again on page load (after the form is submitted, so that the DIV is shown again automatically).

I'm having trouble with this - can anyone help?

try:

$('.show-additional-link').click(function() {return showAdditional(this);});

function showAdditional(e) {
    $(e).parent().next().slideDown();
    $(e).hide();
    return false;
}

and on page load something like showAdditional($('#linkyouwantclicked'))

You can manually trigger events. This should keep the right context for the handlers without any extra hassles.

jQuery(function ($) {
    // when the document has loaded
    $('.show-additional-link')
        .click(function () {    // set up the handler
            // your code here
        })
        .click()                // trigger the handler
    ;
});

$('.show-additional-link').each(function() {makeClickable($(this));}));


function makeClickable(el) { 
    el.click(function(){
        el.parent().next().slideDown();
        el.hide();
        return false;
    });
}

Did you try:

<script type="text/javascript">
  function showAdditional() {
    $('.show-additional-link').parent().next().slideDown();
    $('.show-additional-link').hide();
  }
</script>

and change your show-additional-link href to "javascript:showAdditional()" ?
