# ‹‹ homejQuery Expander Plugin

## Example 1

The following definition list has two expanders assigned to it, one for the first answer and one for the other two. The second expander has a number of options set for it, including three "callbacks" which invoke functions at three separate moments.

    $(document).ready(function() {
      $('dl.expander dd:eq(0)').expander();

      $('dl.expander dd:gt(0)').expander({
        collapseTimer: 4000,
        beforeExpand: function() {
          $(this).parent().parent().append('<div class="success">before expand.</div>');
        },
        afterExpand: function() {
          $(this).parent().parent().append('<div class="success">after expand.</div>');
        },
        onCollapse: function(byUser) {
          var by = byUser ? 'user' : 'timer';
          $(this).parent().parent().append('<div class="success">on collapse (' + by + ').</div>');
        }
      });
    });

Benedick's Question: I pray you, what is he?
  Beatrice's Answer: Why, he is the prince's jester: a very dull fool; only his gift is in devising impossible slanders: none but libertines delight in him; and the commendation is not in his wit, but in his villany; for he both pleases men and angers them, and then they laugh at him and beat him. I am sure he is in the fleet: I would he had boarded me. (Much Ado About Nothing, II.1)
Benedick's Question: I do love nothing in the world so well as you: is not that strange?
  Beatrice's Answer: As strange as the thing I know not. It were as possible for me to say I loved nothing so well as you: but believe me not; and yet I lie not; I confess nothing, nor I deny nothing. (Much Ado About Nothing, IV.1)
Karl's Question: Why aren't you using another question from Much Ado About Nothing here?
  Karl's Answer: Because I'm lazy. And besides, this demo is getting a little too pretentious.

Note that the third answer does not have a "read more" link because it's using the default value of 100 characters and 4 "widow" words as its cut-off. No sense in linking to read more when there isn't much more to read.

## Example 2

The following list items have a single expander assigned to them with a few custom options set.

    $('ul.expander li').expander({
      slicePoint: 50,
      widow: 2,
      expandEffect: 'show',
      userCollapseText: '[^]'
    });

- Run a marathon [...]and qualify for Boston.
- Climb Mount Everest, or at least Mount Pleasant, and take some pictures while I'm there.
- Become proficient at the pogo stick.

Hey, why is the first `<li>` collapsed? Well, the first list item is a trick! Rather than let the plugin decide where to truncate the text, I put the links and the span directly in the HTML. It looks like this:

    <li>Run a marathon <span class="read-more"><a href="#">[...]</a></span><span class="details">and qualify for Boston.</span></li>

## Example 3

The Expander Plugin now works for block-level elements, too.

    $('div.expander').expander();
