本文介绍了Vue 实现展开折叠效果的示例代码,分享给大家,具体如下:

效果如见:

Vue 实现展开折叠效果的示例代码

1.html代码

<!DOCTYPE html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
  <title>js文本段落展开和收拢效果</title>
  <script type="text/javascript" src="/UploadFiles/2021-04-02/jquery-1.6.2.min.js">

2.js代码,最关键的

$(function() {
 var slideHeight = 45; // px 定义折叠的最小高度
 var defHeight = $('#wrap').height();
 if(defHeight >= slideHeight) {
 $('#wrap').css('height', slideHeight + 'px');
 $('#read-more').append('<a href="#" rel="external nofollow" >更多</a>');
 $('#read-more a').click(function() {
  var curHeight = $('#wrap').height();
  if(curHeight == slideHeight) {
  $('#wrap').animate({
   height: defHeight
  }, "normal");
  $('#read-more a').html('折叠');
  } else {
  $('#wrap').animate({
   height: slideHeight
  }, "normal");
  $('#read-more a').html('更多');
  }
  return false;
 });
 }
});

3.css代码

#container {
 margin: 0 auto;
 width: 600px;
 border: 1px solid #3bb2d0;
}
 
#wrap {
 position: relative;
 padding: 10px;
 overflow: hidden;
}
 
#read-more {
 padding: 5px;
 background: #fff;
 color: #333;
}
 
#read-more a {
 padding-right: 22px;
 no-repeat 100% 50%;
 font-weight: bold;
 text-decoration: none;
}
 
#read-more a: hover {
 color: #000;
}

除了使用jQuery的方式实现上述效果,同样可以在Vue实现,下面是解决办法:

1、创建collapse.js文件

const elTransition =
 "0.3s height ease-in-out, 0.3s padding-top ease-in-out, 0.3s padding-bottom ease-in-out";
const Transition = {
 "before-enter"(el) {
  el.style.transition = elTransition;
  if (!el.dataset) el.dataset = {};

  el.dataset.oldPaddingTop = el.style.paddingTop;
  el.dataset.oldPaddingBottom = el.style.paddingBottom;

  el.style.height = 0;
  el.style.paddingTop = 0;
  el.style.paddingBottom = 0;
 },

 enter(el) {
  el.dataset.oldOverflow = el.style.overflow;
  if (el.scrollHeight !== 0) {
   el.style.height = el.scrollHeight + "px";
   el.style.paddingTop = el.dataset.oldPaddingTop;
   el.style.paddingBottom = el.dataset.oldPaddingBottom;
  } else {
   el.style.height = "";
   el.style.paddingTop = el.dataset.oldPaddingTop;
   el.style.paddingBottom = el.dataset.oldPaddingBottom;
  }

  el.style.overflow = "hidden";
 },

 "after-enter"(el) {
  el.style.transition = "";
  el.style.height = "";
  el.style.overflow = el.dataset.oldOverflow;
 },

 "before-leave"(el) {
  if (!el.dataset) el.dataset = {};
  el.dataset.oldPaddingTop = el.style.paddingTop;
  el.dataset.oldPaddingBottom = el.style.paddingBottom;
  el.dataset.oldOverflow = el.style.overflow;

  el.style.height = el.scrollHeight + "px";
  el.style.overflow = "hidden";
 },

 leave(el) {
  if (el.scrollHeight !== 0) {
   el.style.transition = elTransition;
   el.style.height = 0;
   el.style.paddingTop = 0;
   el.style.paddingBottom = 0;
  }
 },

 "after-leave"(el) {
  el.style.transition = "";
  el.style.height = "";
  el.style.overflow = el.dataset.oldOverflow;
  el.style.paddingTop = el.dataset.oldPaddingTop;
  el.style.paddingBottom = el.dataset.oldPaddingBottom;
 }
};

export default {
 name: "collapseTransition",
 functional: true,
 render(h, { children }) {
  const data = {
   on: Transition
  };
  return h("transition", data, children);
 }
};

2、在.vue组件中引入

<template>
  <div class="container">
    <button @click="isActive = !isActive">展开/折叠</button>
    <collapse>
      <div class="container" v-show="isActive">
        <h2>欢迎大家品尝Pizza!</h2>
        <h5>这里有你非常喜欢的Pizza!</h5>
      </div>
    </collapse>
  </div>
</template>
<script>
import collapse from "../assets/js/collapse.js";
export default {
 data() {
  return {
   isActive: false
  };
 },
 components: {
  collapse
 }
};
</script>

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!

昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。

这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。

而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
