我正在尝试根据点击折叠和扩展div。具有以下代码的东西工作正常，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，它应该被折叠。
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;
});
<?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; ?>
请帮我解决一下！
<div class="greycont">

答案 0 :(得分：0)
让我觉得你的代码比你可能需要的代码多得多。
以下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;
}<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
