Question

如果段落扩展到特定高度，我想隐藏div的文本，然后单击一个将高度更改为完全的按钮，但是通过单击该按钮，所有div都会受到影响，我想仅对该按钮的父div设置动画，而不仅仅是行在这种情况下，只有第一个div扩展了该高度才会受到按钮点击的影响

$(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;
}

希望我的代码段可以以某种方式为您提供帮助。

今天天气愉快，

$(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');

      //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'});
  }  
});


});

.description {
  width: 250px;
  height: 120px;
  display: block;
  overflow: hidden;
  word-break: break-word;
  word-wrap: break-word;
}
