如果段落延伸特定高度，并且通过单击高度更改为完整的按钮，我想隐藏 div 的文本，但通过单击该按钮，所有 div 都会受到影响，我只想为该按钮的父 div 制作动画，而不仅仅是行在这种情况下，只有第一个延伸该高度的 div 受到按钮单击的影响
$(document).ready(function() {
var text = $('.description'),
btn = $('.btn-overflow'),
h = text[0].scrollHeight;
if(h > 120) {
btn.addClass('less');
btn.css('display', 'block');
}
$(".emp-bio .btn-overflow").click(function(e) {
e.stopPropagation();
e.preventDefault();
if ($(this).hasClass('less')) {
$(this).removeClass('less');
$(this).addClass('more');
$(this).text('Show less');
text.animate({'height': h});
} else {
$(this).addClass('less');
$(this).removeClass('more');
$(this).text('Show more');
text.animate({'height': '120px'});
}
});
});.description {
width: 250px;
height: 120px;
display: block;
overflow: hidden;
word-break: break-word;
word-wrap: break-word;

e.stopPropagation();
e.preventDefault();
if ($(this).hasClass('less')) {
$(this).removeClass('less');
$(this).addClass('more');
$(this).text('Show less');
//use siblings to access .description in same level.
$(this).siblings( ".description" ).animate({'height': h});
} else {
$(this).addClass('less');
$(this).removeClass('more');
$(this).text('Show more');
//use siblings to access .description in same level.
$(this).siblings( ".description" ).animate({'height': '120px'});
}
