我正在使用一个脚本来限制段落的几个单词，所以对于那个 m 使用 readmore 的脚本..但问题是它在我点击文本的任何地方折叠段落，而我希望它在点击 >>更多时折叠链接..所以我请求任何人帮助我解决这个问题，它不会接受点击文本。

                    <!--readmore script-->
                <script type="text/javascript">

                $(function () {

                    // Grab all the excerpt class
                    $('.excerpt').each(function () {

                        // Run formatWord function and specify the length of words display to viewer
                        $(this).html(formatWords($(this).html(), 15));

                        // Hide the extra words
                        $(this).children('span').hide();

                    // Apply click event to read more link
                    }).click(function () {

                        // Grab the hidden span and anchor
                        var more_text = $(this).children('span.more_text');
                        var more_link = $(this).children('a.more_link');

                        // Toggle visibility using hasClass
                        // I know you can use is(':visible') but it doesn't work in IE8 somehow...
                        if (more_text.hasClass('hide')) {
                            more_text.show();
                            more_link.html(' &raquo; hide');        
                            more_text.removeClass('hide');
                        } else {

                            more_text.addClass('hide');
                        }

                        return false;

                    });
                });

                // Accept a paragraph and return a formatted paragraph with additional html tags
                function formatWords(sentence, show) {

                    for (i = 0; i < words.length; i++) {

                        // process the rest of the words
                        } else {

                            // add a span at start
                            if (i == (show + 1)) new_sentence += ' <span class="more_text hide">';      

                            new_sentence += words[i] + ' ';

                            // close the span tag and add read more link in the very end
                            if (words[i+1] == null) new_sentence += '</span><a href="#" class="more_link"> &raquo; more</a>';
