vue也可以 slidedown

vue也可以实现jquery的 slidedown

结合原生js与transition 动画完成slidedown

   clickBy(){//点击事件let slide = { //down up事件      down : function(div){div.style.height='140px';},              up : function(div){div.style.height='0';}}function toggleSlide(id,s){var div = document.getElementById(id),div_height = div.offsetHeight;div.style.transition='height '+s+'ms';  div.style.overflow='hidden';                    if(div_height){slide.up(div);}else{slide.down(div);}}toggleSlide('groupRadioBox','300')//调用事件传值let classN=this.$refs.caret.className//获取类名if(classN=='el-icon-caret-bottom'){//切换图标类名this.$refs.caret.setAttribute("class",'el-icon-caret-right')}else{this.$refs.caret.setAttribute("class",'el-icon-caret-bottom')}}
