屏幕閱讀器的易用性

-1

如何製作div的一部分對於使用jQuery的屏幕閱讀器不可見？我試圖在某些文本上實現readmore readless功能，但我面臨屏幕閱讀器的問題，但我必須在這裏允許accessibilty。這裏是我的代碼，我將展示基於行數我的DIV的一部分：屏幕閱讀器的易用性

$(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之中：

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