vue开发移动端时的准备工作

1.在index.html文件head中添加

<meta name="viewport" content="width=device-width,initial-scale=1,maximum-scale=1,minimum-scale=1,user-scalable=no">

2.添加css reset重定义浏览器默认样式

html,
body,
p,
ol,
ul,
li,
dl,
dt,
dd,
blockquote,
figure,
fieldset,
legend,
textarea,
pre,
iframe,
hr,
h1,
h2,
h3,
h4,
h5,
h6 {
  margin: 0;
  padding: 0;
}
 
h1,
h2,
h3,
h4,
h5,
h6 {
  font-size: 100%;
  font-weight: normal;
}
 
ul {
  list-style: none;
}
 
button,
input,
select,
textarea {
  margin: 0;
}
 
html {
  box-sizing: border-box;
}
 
* {
  box-sizing: inherit;
}
*:before, *:after {
  box-sizing: inherit;
}
 
img,
embed,
object,
audio,
video {
  height: auto;
  max-width: 100%;
}
 
iframe {
  border: 0;
}
 
table {
  border-collapse: collapse;
  border-spacing: 0;
}
 
td,
th {
  padding: 0;
  text-align: left;
}

然后在main.js中引入

    

 3.添加boder.css，实现1px边框，避免实际边框1px看起来比较粗的问题

@charset "utf-8";
.border,
.border-top,
.border-right,
.border-bottom,
.border-left,
.border-topbottom,
.border-rightleft,
.border-topleft,
.border-rightbottom,
.border-topright,
.border-bottomleft {
  position: relative;
}
 
.border::before,
.border-top::before,
.border-right::before,
.border-bottom::before,
.border-left::before,
.border-topbottom::before,
.border-topbottom::after,
.border-rightleft::before,
.border-rightleft::after,
.border-topleft::before,
.border-topleft::after,
.border-rightbottom::before,
.border-rightbottom::after,
.border-topright::before,
.border-topright::after,
.border-bottomleft::before,
.border-bottomleft::after {
  content: "\0020";
  overflow: hidden;
  position: absolute;
}
 
/* border
 * 因，边框是由伪元素区域遮盖在父级
 * 故，子级若有交互，需要对子级设置
 * 定位 及 z轴
 */
.border::before {
  box-sizing: border-box;
  top: 0;
  left: 0;
  height: 100%;
  width: 100%;
  border: 1px solid #eaeaea;
  transform-origin: 0 0;
}
 
.border-top::before,
.border-bottom::before,
.border-topbottom::before,
.border-topbottom::after,
.border-topleft::before,
.border-rightbottom::after,
.border-topright::before,
.border-bottomleft::before {
  left: 0;
  width: 100%;
  height: 1px;
}
 
.border-right::before,
.border-left::before,
.border-rightleft::before,
.border-rightleft::after,
.border-topleft::after,
.border-rightbottom::before,
.border-topright::after,
.border-bottomleft::after {
  top: 0;
  width: 1px;
  height: 100%;
}
 
.border-top::before,
.border-topbottom::before,
.border-topleft::before,
.border-topright::before {
  border-top: 1px solid #eaeaea;
  transform-origin: 0 0;
}
 
.border-right::before,
.border-rightbottom::before,
.border-rightleft::before,
.border-topright::after {
  border-right: 1px solid #eaeaea;
  transform-origin: 100% 0;
}
 
.border-bottom::before,
.border-topbottom::after,
.border-rightbottom::after,
.border-bottomleft::before {
  border-bottom: 1px solid #eaeaea;
  transform-origin: 0 100%;
}
 
.border-left::before,
.border-topleft::after,
.border-rightleft::after,
.border-bottomleft::after {
  border-left: 1px solid #eaeaea;
  transform-origin: 0 0;
}
 
.border-top::before,
.border-topbottom::before,
.border-topleft::before,
.border-topright::before {
  top: 0;
}
 
.border-right::before,
.border-rightleft::after,
.border-rightbottom::before,
.border-topright::after {
  right: 0;
}
 
.border-bottom::before,
.border-topbottom::after,
.border-rightbottom::after,
.border-bottomleft::after {
  bottom: 0;
}
 
.border-left::before,
.border-rightleft::before,
.border-topleft::after,
.border-bottomleft::before {
  left: 0;
}
 
@media (max--moz-device-pixel-ratio: 1.49), (-webkit-max-device-pixel-ratio: 1.49), (max-device-pixel-ratio: 1.49), (max-resolution: 143dpi), (max-resolution: 1.49dppx) {
  /* 默认值，无需重置 */
}
 
@media (min--moz-device-pixel-ratio: 1.5) and (max--moz-device-pixel-ratio: 2.49), (-webkit-min-device-pixel-ratio: 1.5) and (-webkit-max-device-pixel-ratio: 2.49), (min-device-pixel-ratio: 1.5) and (max-device-pixel-ratio: 2.49), (min-resolution: 144dpi) and (max-resolution: 239dpi), (min-resolution: 1.5dppx) and (max-resolution: 2.49dppx) {
  .border::before {
    width: 200%;
    height: 200%;
    transform: scale(.5);
  }
 
  .border-top::before,
  .border-bottom::before,
  .border-topbottom::before,
  .border-topbottom::after,
  .border-topleft::before,
  .border-rightbottom::after,
  .border-topright::before,
  .border-bottomleft::before {
    transform: scaleY(.5);
  }
 
  .border-right::before,
  .border-left::before,
  .border-rightleft::before,
  .border-rightleft::after,
  .border-topleft::after,
  .border-rightbottom::before,
  .border-topright::after,
  .border-bottomleft::after {
    transform: scaleX(.5);
  }
}
 
@media (min--moz-device-pixel-ratio: 2.5), (-webkit-min-device-pixel-ratio: 2.5), (min-device-pixel-ratio: 2.5), (min-resolution: 240dpi), (min-resolution: 2.5dppx) {
  .border::before {
    width: 300%;
    height: 300%;
    transform: scale(.33333);
  }
 
  .border-top::before,
  .border-bottom::before,
  .border-topbottom::before,
  .border-topbottom::after,
  .border-topleft::before,
  .border-rightbottom::after,
  .border-topright::before,
  .border-bottomleft::before {
    transform: scaleY(.33333);
  }
 
  .border-right::before,
  .border-left::before,
  .border-rightleft::before,
  .border-rightleft::after,
  .border-topleft::after,
  .border-rightbottom::before,
  .border-topright::after,
  .border-bottomleft::after {
    transform: scaleX(.33333);
  }
}

然后在main.js中引入

 

 4.移动端300ms点击延迟问题

①npm install fastclick --save

②在main.js引入

import fastClick from 'fastclick'

fastClick.attach(document.body)
