VUE:整屏滚动效果


这里需要用的是vue-fullpage插件

安装

npm install vue-fullpage --save
npm install animate.css --save

配置

在main.js需要引入该插件的css和js文件

import 'vue-fullpage/vue-fullpage.css'
import VueFullpage from 'vue-fullpage'
Vue.use(VueFullpage)

页面代码

在page-wp容器上加v-fullpage指令,v-fullpage的值是fullpage的配置 在page容器上加v-animate指令,v-animate的值是animate.css的动画效果

<template>
  <div id="app">
    <div class="fullpage-container">
      <div class="fullpage-wp" v-fullpage="opts">
        <div class="page-1 page">
          <p class="part-1" v-animate="{value: 'bounceInLeft'}">vue-fullpage</p>
        </div>
        <div class="page-2 page">
          <p class="part-2" v-animate="{value: 'bounceInRight'}">vue-fullpage</p>
        </div>
        <div class="page-3 page">
          <p class="part-3" v-animate="{value: 'bounceInLeft', delay: 0}">vue-fullpage</p>
          <p class="part-3" v-animate="{value: 'bounceInRight', delay: 600}">vue-fullpage</p>
          <p class="part-3" v-animate="{value: 'zoomInDown', delay: 1200}">vue-fullpage</p>
        </div>
      </div>
    </div>
  </div>
</template>

<script>

export default {
  name: 'App',
  data () {
    return {
      opts: {
        start: 0,
        dir: 'v',
        loop: false,
        duration: 500,
        stopPageScroll: true,
        beforeChange: function (prev, next) {
          console.log(prev,next)
        },
        afterChange: function (prev, next) {
          console.log(prev,next)
        }
      }
    }
  }
}
</script>

  margin: 0;
  padding: 0;

  position: absolute;

CSS | 将彩色图片转换成黑白色


需求

净月投资热力图PC端涉及个列表图片,鼠标放上去之后图片变成有颜色的那种。
那就先要让它变成黑白的

代码如下

<img src="..." class="graypic" />
.graypic { 
    -webkit-filter: grayscale(100%);
    -moz-filter: grayscale(100%);
    -ms-filter: grayscale(100%);
    -o-filter: grayscale(100%);
    filter: grayscale(100%);
    filter: gray;
}

element-ui table列合并--支持多个列(vue)


驻场的最后一天,小伙伴列的合并碰到了问题,帮忙解决一下。

效果如图:
微信截图_20201219105321.png

具体代码:

<el-table
        :data="tableData"
        :span-method="arraySpanMethod"
        border
        style="width: 100%; margin-top: 20px">
        <el-table-column
          prop="id"
          label="ID"
          width="180">
        </el-table-column>
        <el-table-column
          prop="name"
          label="姓名">
        </el-table-column>
        <el-table-column
          prop="amount1"
          label="数值 1(元)">
        </el-table-column>
        <el-table-column
          prop="amount2"
          label="数值 2(元)">
        </el-table-column>
        <el-table-column
          prop="amount3"
          label="数值 3(元)">
        </el-table-column>
      </el-table>

CSS:鼠标悬停整体上升


驻场管委会需要个悬停的效果:

.mouse_onshow{background:white;margin:0 5px;}
.mouse_onshow:hover{
    transform:translate(0,-10px);  
   -webkit-transform:translate(0,-10px);    
  -moz-transform:translate(0,-10px);    
  -o-transform:translate(0,-10px);    
  -ms-transform:translate(0,-10px);
    box-shadow:0px 5px 20px #ccc;
}

1.鼠标悬停图片变大

:hover {

  -webkit-transform: scale(1.1);

  -moz-transform: scale(1.1);

  -o-transform: scale(1.1);

  -ms-transform: scale(1.1);

}

缓慢变化需要在包住图片的外层加上:-webkit-transition: all 0.5s; -moz-transition: all 0.5s; -o-transition: all 0.5s; -ms-transition: all 0.5s;

变大不超出的话就加上overflow:hidden;

2.鼠标悬停整体旋转

:hover {

  transform:rotate(360deg);

  -webkit-transform:rotate(360deg);

  -moz-transform:rotate(360deg);

  -o-transform:rotate(360deg);

  -ms-transform:rotate(360deg);

}

缓慢变化需要在包住图片的外层加上:transition:All 0.4s ease-in-out;-webkit-transition:All 0.4s ease-in-out;-moz-transition:All 0.4s ease-in-out;-o-transition:All 0.4s ease-in-out;

3.鼠标悬停整体旋转放大

:hover {

  transform:rotate(360deg) scale(1.2);

  -webkit-transform:rotate(360deg) scale(1.2);

  -moz-transform:rotate(360deg) scale(1.2);

  -o-transform:rotate(360deg) scale(1.2);

  -ms-transform:rotate(360deg) scale(1.2);

}

缓慢变化需要在包住图片的外层加上:transition:All 0.4s ease-in-out;-webkit-transition:All 0.4s ease-in-out;-moz-transition:All 0.4s ease-in-out;-o-transition:All 0.4s ease-in-out;

4.鼠标悬停整体上升

:hover {

  transform:translate(0,-10px);

  -webkit-transform:translate(0,-10px);

  -moz-transform:translate(0,-10px);

  -o-transform:translate(0,-10px);

  -ms-transform:translate(0,-10px);

}

缓慢变化需要在包住图片的外层加上:transition:All 0.4s ease-in-out;-webkit-transition:All 0.4s ease-in-out;-moz-transition:All 0.4s ease-in-out;-o-transition:All 0.4s ease-in-out;

需要上升载加一点阴影(加在hover里面):box-shadow:0px 5px 20px #ccc;


CSS:画圆点连线


这回再高新管委会驻场,需要到一个效果,没办法,只能手写 ,来吧!
