统一样式(reset.css与border.css)

reset.css

不同浏览器对相同标签的显示效果，有时候往往不同，那么在做项目的时候就需要对基本的样式进行设置，以达到在不同浏览器下显示效果是相同的，reset.css的作用就在于此。

所有，大家很有必要收藏一下，在做项目的时候直接使用即可。

border.css

该css样式用于解决移动端1像素边框问题。

问题分析：有些手机的屏幕分辨率较高，是2-3倍屏幕。

css样式中border:1px solid red;在2倍屏下，显示的并不是1个物理像素，而是2个物理像素。为了解决这个问题，引入border.css是非常有必要的。

使用方法：在vue项目中的入口文件main.js中引入即可。

// 在入口文件中引入基本样式
import './assets/styles/reset.css'
import './assets/styles/border.css'

vue基础样式应用

用于记录自己经常用到的一些样式

1、文本溢出隐藏

<template slot-scope="scope">
    <div class="text-hidden">{{ scope.row.address }}</div>
</template>

.text-hidden{
 overflow: hidden;
  text-overflow: ellipsis;
  white-space: nowrap;
}

overflow: hidden;
text-weight: ellipsis;
white-space: normal;
word-break: break-all;
word-wrap: break-word;
display: -webkit-box;
-webkit-line-clamp: 1;
-webkit-box-orient: vertical;

2.大的外边框，类似卡片的样式

.shopcheck {
  border: 1px solid #999;
  margin: 20px;
  border-radius: 10px;
  padding: 20px;
  box-shadow: 2px 4px 6px #999;
  background-color: #fff;
}

3、详情普通表格

<el-dialog title="店铺发布详情" :visible.sync="dialogVisible" width="50%">
      <div class="table-d">
        <table border="0" cellspacing="1" cellpadding="0">
          <tr>
            <td style="width: 100px">店铺名</td>
            <td>{{ pub_shop.shop_name }}</td>
          </tr>
          <tr>
            <td style="width: 100px">店铺联系方式</td>
            <td>{{ pub_shop.shop_mobile }}</td>
          </tr>
          <tr>
            <td style="width: 100px">文章标题</td>
            <td>{{ msg.title }}</td>
          </tr>
          <tr>
            <td>类型</td>
            <td>{{ msg.type }}</td>
          </tr>
          <tr>
            <td>店铺地区</td>
            <td>{{ msg.area}}</td>
          </tr>
          <tr>
            <td>店铺详细地址</td>
            <td>{{ msg.address }}</td>
          </tr>
          <tr>
            <td>联系号码</td>
            <td>{{ msg.mobile }}</td>
          </tr>
          <tr>
            <td>发布时间</td>
            <td>{{ msg.create_time }}</td>
          </tr>
          <tr>
            <td>浏览量</td>
            <td>{{ msg.views }}</td>
          </tr>
          <tr>
            <td>文章内容</td>
            <td>{{ msg.content }}</td>
          </tr>
          <tr>
            <td>图片</td>
            <td>
              <el-image v-viewer="{movable: false,title:false}"  :src="msg.images" class="img" ></el-image>
            </td>
          </tr>
        </table>
      </div>
      <span slot="footer" class="dialog-footer">
        <el-button @click="dialogVisible = false">关闭</el-button>
      </span>
    </el-dialog>

.table-d table {
  background: #999;
  width: 100%;
}
.table-d table td {
  background: #fff;
  padding: 20px;
  text-align: center;
  line-height: 1.5;
}

4、input框长度限制

<el-input v-model="inData.name" maxlength="30"  show-word-limit  placeholder="请输入通告标题"></el-input>

5、看图插件的引入( viewer )这个插件比element的image图片操作更多

viewer 文档

npm install v-viewer --save

在main中配置

import Viewer from 'v-viewer'
import 'viewerjs/dist/viewer.css'
Vue.use(Viewer)
Viewer.setDefaults(
  {options:{
    'title':false,
  },
 
})

使用

<el-image v-viewer="{movable: false,title:false}"  :src="msg.images" class="img" ><div slot="error" class="image-slot"> </div></el-image>

和element模态框混用时，出现的层级错乱

.el-dialog__wrapper{
    z-index: 2014 !important;
  }
  .v-modal{
    z-index: 2000 !important;
  }

5、对element表格某列进行修改

<el-table-column prop="address" label="方式"> 
    <template slot-scope="scope">
       <span>{{ scope.row.condition | condition }}</span>
     </template> 
</el-table-column>

表格里的图片样式

<template slot-scope="scope">
      <el-image v-viewer="{movable: false,title:false}"  :src="scope.row.images[0]" class="tableimg"  v-if="scope.row.images[0]" ></el-image>
</template>

6、搜索框

<el-container class="imgsearch"
      ><el-input
        placeholder="请输入要搜索标题或内容"
        prefix-icon="el-icon-search"
        v-model="input2"
        style="width: 300px; margin-right: 20px"
        @input="change"
        @change="search"
        maxlength="255"
      >
      </el-input>
      <div></div>
      <el-select
        v-model="value"
        placeholder="筛选信息类型"
        style="margin-right: 20px"
        :clearable='true'
        @clear='getList'
      >
        <el-option
          v-for="item in options"
          :key="item.value"
          :label="item.label"
          :value="item.value"
        >
        </el-option>
      </el-select>
      <el-button type="primary" @click="search">搜索</el-button>
    </el-container>

7、element 表格中的按钮

<template slot-scope="scope">
    <el-button @click="pay(scope.row)" :plain="true" type="success" size="small">支付</el-button>
    <el-button @click="look(scope.row)" size="small" type="warning" plain>查看</el-button>
    <el-button @click="auth(scope.row)" :plain="true" size="small" type="primary">修改</el-button>
    <el-button type="danger" plain size="small" @click="del(scope.row)" style="margin-right: 10px">删除</el-button>
</template>

9、引用svg图标

<svg-icon :iconClass="classname[index]" class="icon"/>

10、输入框只能输入数字，限制长度

maxlength="4"
oninput = "value=value.replace(/[^\d]/g,'')"

10、设置滚动条样式

::-webkit-scrollbar {
  -webkit-appearance: none;
  width: 7px;
}
::-webkit-scrollbar-thumb {
  border-radius: 4px;
  background-color: rgba(222, 222, 227,.8);
  -webkit-box-shadow: 0 0 1px rgba(255, 255, 255, .5);
}
// 隐藏火狐滚动条
  overflow:auto;
  /* overflow: scroll; */
  overflow-x:hidden;
  overflow-y: scroll;
  scrollbar-width: none;
  scrollbar-color: transparent transparent;
  scrollbar-track-color: transparent;
  -ms-scrollbar-track-color: transparent;

11、element上传走自己的请求

<el-upload
    action="#"
    list-type="picture-card"
    :on-success="uploadImg"
    :on-remove="handleRemove"
    :limit="1"
    :file-list="fileList"
       :http-request="upImg"
>
    <img src="../assets/img/upload.png" class="centerimg" />
</el-upload>

upImg(param) {
      const formData = new FormData();
      formData.append("file", param.file);
      this.$http
        .upLoadImg(formData)
        .then((res) => {
          
        })
        .catch((err) => {
         
        });
    },

12、让文本框textarea不可拖动

textarea{
    resize: none;
}

13.隐藏滚动条

 overflow: scroll;
  overflow-x:hidden;
  overflow-y: scroll;
  scrollbar-width: none;
  scrollbar-color: transparent transparent;
  scrollbar-track-color: transparent;
  -ms-scrollbar-track-color: transparent;

14.抓到element选择器下面的那个弹窗

//  :popper-append-to-body="false"  加上这个字段
<el-select v-model="value" placeholder="选择名称" class="selectList-item" :popper-append-to-body="false" >
              <el-option
                v-for="item in options"
                :key="item.value"
                :label="item.label"
                :value="item.value">
              </el-option>
            </el-select>

.index >>> .el-select-dropdown {
  color: #fff !important;
  background-color:#277fba !important;
  border: none;
  box-shadow: 0 0 10px rgba(255, 255, 255,.3);
}
.index >>> .el-select-dropdown .el-select-dropdown__empty{
  color: #fff !important;
}
.index >>> .el-select-dropdown .el-select-dropdown__item{
 color: #fff !important;
}
.index >>> .el-select-dropdown .hover{
  background: #186192 !important;
}

以上为个人经验，希望能给大家一个参考，也希望大家多多支持。
