javascript - 扩展阅读更多/阅读更少 jQuery 脚本

Question

我有一个很棒的脚本，它使用 jQuery 显示一小部分内容并允许用户阅读更多/更少内容。这是我当前的 fiddle :http://jsfiddle.net/Tqwdh/1/

摘要:当您单击图像时，它需要显示附加文本。

我很想知道如何更新此脚本以允许用户单击关联的图像，并且它将显示更多文本(以及保留文本链接)。

有人可以告诉我如何实现这一目标吗？

这是我的示例HTML:

<article id="post-5" >

            <div class="more-less">    
                <div class="more-block">
                    <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed diam purus, lacinia eget placerat sit amet, bibendum nec nisl. Curabitur a mattis ipsum. Praesent quis nisi in purus malesuada rhoncus. Pellentesque ut quam eget libero congue lobortis. Nunc sed quam ac erat lobortis eleifend. Donec elementum sodales cursus. Aliquam porttitor massa nisi, in laoreet turpis. Sed consequat condimentum lorem ut dignissim. Sed hendrerit mauris ut massa fermentum laoreet. Pellentesque a leo vitae enim dictum lobortis. Praesent commodo feugiat velit iaculis malesuada.</p>
                    <p>Phasellus id elit ac lacus faucibus ullamcorper. Etiam ullamcorper pretium tellus, ut pharetra ante pulvinar vel. Sed neque diam, semper vel rhoncus non, congue ut sapien. Integer a mi eget libero elementum lobortis. Donec hendrerit egestas ligula sit amet eleifend. Curabitur pharetra venenatis tempor. Quisque pulvinar malesuada justo, ut euismod arcu pharetra vitae. Cras lobortis, ligula id euismod euismod, ipsum risus varius urna, faucibus gravida lectus mi nec nulla. Fusce eleifend fringilla nibh ut vulputate. Vivamus sagittis leo metus. Etiam facilisis convallis lacus adipiscing hendrerit. Duis ultricies euismod libero, nec blandit est semper a. Phasellus sit amet justo sed quam elementum lobortis. Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>
                </div>
            </div>

            <p>
                <a href="#" title="News Item 1"><img src="http://placehold.it/300x187" alt="News Item 1" width="300" height="187" /></a>
            </p>            

        </article><!-- #post-## -->

和我的jQuery:

$(function(){
        // The height of the content block when it's not expanded
        var adjustheight = 130;
        // The "more" link text
        var moreText = "Click to read more...";
        // The "less" link text
        var lessText = "Click to read less...";
        // Sets the .more-block div to the specified height and hides any content that overflows
        $(".more-less .more-block").css('height', adjustheight).css('overflow', 'hidden');
        // The section added to the bottom of the "more-less" div
        $(".more-less").append('<p style="display:block;margin-top:8px"><a href="#" class="adjust"></a></p>');
        $("a.adjust").text(moreText);
        $(".adjust").toggle(function() {
                $(this).parents("div:first").find(".more-block").css('height', 'auto').css('overflow', 'visible');
                // Hide the [...] when expanded
                $(this).parents("div:first").find("p.continued").css('display', 'none');
                $(this).text(lessText);
            }, function() {
                $(this).parents("div:first").find(".more-block").css('height', adjustheight).css('overflow', 'hidden');
                $(this).parents("div:first").find("p.continued").css('display', 'block');
                $(this).text(moreText);
        });
        });

谢谢你:-)

您可以像这样向 img 添加一个点击处理程序: DEMO

$(function(){
    $('img').click(function(){
        $(this).closest('article').find('.adjust').click();
    });
});​
