我试图在单击时切换图像。它部分工作，但部分不工作 :'(
演示： http://jsfiddle.net/Tqwdh/4/ 。

当我单击大图像时，较小的图像会发生变化（从 50x50 变为 151x151）- 欢呼！

但是当我单击“阅读更多”文本时，小图像仍是同一图像。 当我单击“阅读更多”文本时，小的嵌套图像需要更改。

有人可以告诉我如何解决这个问题吗？

我已附上我的 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);
        });
        });

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

        $(function(){ 
           $("article").click(function(){ 
           $("img.small").attr('src',  
                        ($("img.small").attr('src') == 'http://placehold.it/50x50'  
                    ? 'http://placehold.it/151x151'  
                    : 'http://placehold.it/50x50' 
                             ) 
                        )  
            }); 
        }); 

和我的 HTML :

<article id="post-5" >

            <div class="more-less">    
                <div class="more-block">

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>
                <img src="http://placehold.it/50x50" class="small" style="position:absolute;margin-left: 240px;margin-top: 127px;" />
                <a href="#" title="News Item 1"><img src="http://placehold.it/300x187" alt="News Item 1" width="300" height="187" /></a>
            </p>            

        </article>

非常感谢您的指点。
