如何使用jquery使屏幕阅读器看不到div的一部分？我试图在某些文本上实现readmore readless功能但我面临屏幕阅读器的问题，但我必须允许accessibilty在这里。这是我的代码，我将根据行数显示我的div的一部分：

$(document).ready(function() {
 var divHeight,l=3;
 $('.comment').each(function() {
 var $this = $(this),divHeight;
 var $content = $this.find(".text-content"),
   lineHeight= $content.css('line-height');
   divHeight= ((parseInt(l)+3)*parseInt(lineHeight))+"px";
   if($content.hasClass("short-text")){
      $content.css("height","auto");
   }
   else{
    $content.addClass("short-text");
    $content.css("overflow","hidden");
    $content.css("height",divHeight);
    $content.on("focus",function(){
      $(this).attr('aria-hidden', 'false');
    })
   }
   html='<p class="'+'para'+'"><a href="#" class="morelink morelinkStyle">' + 'more' + '</a></p></span>';
   $this.append(html);
 });
 $(".morelink").click(function(){
    var $this = $(this),
    $elem=$this.parents().find(".text-content");
    if ($elem.hasClass("short-text")) {
        $elem.removeClass("short-text");
        $this.html('less');
        divHeight = $elem.height();
        $elem.css("height","auto");
    } else {
        $elem.addClass("short-text");
        $elem.on("focus",function(){
            console.log($(this));
            $(this).css("border","2px solid red");
      $(this).attr('aria-hidden', 'false');
       })
        $this.html('more');
        $elem.css("height",divHeight);
        $elem.css("overflow","hidden");
    }
    return false;
    });

HTML正在：

<div class="comment">
<article class="text-content">

Answer 1

编辑高度＆amp; div的溢出属性不会隐藏屏幕阅读器中的内容。您需要在短文本类中使用display：none。（另外，在CSS中编写类更简单，只需使用jquery添加/删除类名）。

几个月前，我的任务是解决在保持WCAG 2.0可访问性的同时实现“阅读更多”/“阅读更少”链接的相同问题。

如果您不反对使用Bootstrap和jQuery，我有一个非常好的解决方案。引导程序collapse使它成为可能。
