javascript - 单击触发按钮在“阅读更多”和“阅读更少”按钮中不起作用

Question

我正在尝试制作“多读”和“少读”按钮。一切都很好，我总共有 4 个 div，其中字符受到限制，字符也受到限制，甚至按钮也工作正常，问题是按钮在某些 div 中工作，在某些 div 中不起作用，我不明白有什么问题吗？

function limitCharacters(){
    $('.limit-characters').each(function(){
        var element = $(this);
        // var element = $('.limit-characters');
        var elementHtml = element.html();
        element.prepend(elementHtml);
        element.find("p:first").addClass("limited");
        element.find("p:last").addClass("unlimited hide-element");
        var limitedElement = element.find('.limited');
        var limitedElementString = limitedElement.text();
        var subStringedString = limitedElementString.substring(0,500);
        limitedElement.html(subStringedString);
        var buttonElement = '<a href="#" class="btn btn-sample3 btn-sm actionButton ">Read More</a>';
        element.append(buttonElement);
        var button = $(".actionButton");
        button.click(function(e){
            $(this).parent().find(".unlimited").toggleClass("hide-element");
            $(this).parent().find(".limited").toggleClass("hide-element");
            $(this).toggleClass("read-less");
            if($(this).hasClass("read-less")){
                $(this).html("Read Less");
            }else{
                $(this).html("Read More");
            }
            e.preventDefault();
        });
    });
}

.hide-element{
  display:none;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="limit-characters">

问题出在 var button = $(".actionButton"); 中，您应该选择 element 内的 .actionButton .

var button = element.find(".actionButton");
