问题描述
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全屏的按钮，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，只有延伸该高度的第一个div会受到按钮点击的影响
I want to hide the text of div if paragraph extend a specific height and by clicking a button that height changes to full but by clicking the button all divs are affected I want to animate only parent div of that button not just line in this case where only first div that extends that height is affected by button click
$(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'});
}
});
});
