jQuery Read More 容器扩展问题

Question

我正在尝试根据点击折叠和展开 div。以下代码运行良好，但容器始终在页面加载时保持扩展。所以我想做相反的事情。当页面加载时，它应该是折叠的。

jQuery

var showTotalChar = 200, showChar = "read more", hideChar = "less";
$('.review_item').each(function () {
    var content = $(this).html();

    if (content.length > showTotalChar) {
        var con = content.substr(0, showTotalChar);
        var hcon = content.substr(showTotalChar, content.length - showTotalChar);
        var txt = con + '<span class="morectnt"><span>' + hcon + '</span><span class="read-more sample"><a href="" class="clickme">' + hideChar + '</a></span>';
        $(this).html(txt);
    }
});
$(".clickme").click(function () {
    if ($(this).hasClass("sample")) {
        $(this).removeClass("sample");
        $(this).text(hideChar);
    } else {
        $(this).addClass("sample");
        $(this).text(showChar);
    }
    console.log($(this).parent().prev());
    $(this).parent().prev().toggle();
    $(this).prev().toggle();
    return false;
});

HTML/PHP

<?php
foreach ( $product[ 'review' ] as $review ): ?>
    <div class="greycont">
        <img src="<?php echo $review[ 'image_url' ] ?>"
             alt="<?php echo $review[ 'customer' ] ?>">
        <h2><?php echo $review[ 'review_heading' ] ?></h2>
        <div class="null"></div><!-- this div is just to avoid read more issue -->
        <div class="review_item">
            <?php //echo $review[ 'review_content' ] ?>
            <?php eWC_text_to_paragraph( $review[ 'review_content' ] ) ?>
        </div>
<!--                                <span class="read-more"><a href="#" class="clickme">read more...</a></span>-->
    </div><!-- end div class greycont -->
<?php endforeach; ?>

请帮我解决它！

令我震惊的是，您的代码比您可能需要的要多得多。

这是我认为您的目标设置的简化版本：

$(document).ready(function(){
    
    $('.review_item p:nth-of-type(3)').slideToggle();
    $('.toggle').eq(1).toggle();

    $('.toggle').click(function(){
        $('.review_item p:nth-of-type(3)').slideToggle();
        $('.toggle').toggle();
    });

});

.toggle {
color: rgb(0,0,255);
text-decoration: underline;
cursor: pointer;
}
