• 关于使用vue进行考试页面的开发


    //页面分为左右两部分,下面是主要的代码
    <div class="container"> <el-container style="height: calc(100vh - 90px); border: 1px solid #eee"> <el-aside width="300px" style="background-color: #EBEBEB" > <el-image :src="src" class="showImg" > <div slot="error" class="image-slot" > <i class="el-icon-picture-outline"></i> </div> </el-image> <el-form ref="form" v-model="form" size="mini" style=" 270px;margin-left: 30px" label-position="left" > <el-form-item label="姓名:" label-width="60px" > <span>{{ form.userTitle }}</span> </el-form-item> <el-form-item label="身份证号:" label-width="90px" > <span>{{ form.userIdcard }}</span> </el-form-item> <el-form-item label="单位:" label-width="60px" > <span>{{ form.corpName }}</span> </el-form-item> </el-form> <div style="height: 50px;line-height: 50px;background-color:#DDDDDD; margin-left: 10px; 280px"> <span style="font-size: 18px;font-weight:700;color: rgb(96, 98, 102);margin-left: 100px">试题导航</span> </div> <div class="note"> <div style="background-color: #7D7D7D;margin-left: 30px" class="all" ></div> <span class="textStyle">全部</span> <div style="background-color: #05C826;" class="all" ></div> <span class="textStyle">正确</span> <div style="background-color: #E70012" class="all" ></div> <span class="textStyle">错误</span> </div> <ul class="sole"> <li v-for="(item,index) in list" :key="index" :class="item.title" :style="{background:item.color}" @click="toTegional(index)" > {{ index+1 }} </li> </ul> </el-aside> <el-container> <el-header style="text-align: left; font-size: 14px;height: 60px"> <div style="margin: 20px 20px 0"> <span v-if="isReady" style=" font-family: Arial;" >共计试题{{ count }}道,已做{{ finished }}道,完成率{{ rate }}%,答对{{ successCount }}道,正确率{{ unRate }}%,总分:{{ allScore }},得分:{{ trueScore }}</span> <span v-else style=" font-family: Arial;" >共计试题{{ count }}道,已做{{ finished }}道,完成率{{ rate }}%</span> <span class="timeruning" style="margin-left: 20px" >考试时间共1小时30分钟,距离考试结束还有{{ hr }}:{{ min }}:{{ sec }}</span> <el-button type="text" style="color:#1e8cfb;float:right;padding: 0 0 0" :disabled="isSubmit" @click="handleClick()" > 提交 </el-button> </div> </el-header> <el-main> <div ref="rightContent" style="height: calc(100vh - 160px);" > <div v-for="(item,index) in list" :key="index" > <el-card :id="'a'+index" class="box-card" > <div style="background-color: #EEEEEE; 100%; height: 80px"> <div style="padding-top: 20px"> <p style="display: inline;margin-left: 20px"> {{ index + 1 }}.{{ item.title }} </p> <p v-if="item.type=='1'" style="display: inline;margin-left: 10px" > (单选题) </p> <p v-else-if="item.type==='2'" style="display: inline;margin-left: 10px" > (多选题) </p> <p v-else-if="item.type==='3'" style="display: inline;margin-left: 10px" > (判断题) </p> <p v-if="item.type!=='3'&&isReady" style="display: inline;margin-left: 10px" > 正确答案:{{ item.answer }} </p> <p v-else-if="item.type==='3'&&item.answer==='1'&&isReady" style="display: inline;margin-left: 10px" > 正确答案:对 </p> <p v-else-if="item.type==='3'&&item.answer==='0'&&isReady" style="display: inline;margin-left: 10px" > 正确答案:错 </p> <p style="display: inline;float: right;margin-right: 20px"> 本题{{ item.score }}分 </p> </div> </div> <el-radio-group v-if="item.type==='1'" v-model="item.examValue" @change="onChange(item)" > <ul> <li v-for="(item1,index1) in item.examQBankDetailsList" :key="index1" style="margin:10px 0 10px 20px" > <el-radio :value="item1.options" :label="order[index1]" :disabled="isReady" > {{ order[index1] }}.{{ item1.options }} </el-radio> </li> </ul> </el-radio-group> <el-checkbox-group v-else-if="item.type==='2'" v-model="item.examValue" @change="onChange(item)" > <ul> <li v-for="(item1,index1) in item.examQBankDetailsList" :key="index1" style="margin:10px 0 10px 20px" > <el-checkbox :value="item1.options" :label="order[index1]" :disabled="isReady" > {{ order[index1] }}.{{ item1.options }} </el-checkbox> </li> </ul> </el-checkbox-group> <el-radio-group v-else-if="item.type==='3'" v-model="item.examValue" @change="onChange(item)" > <ul> <li style="margin:10px 0 10px 20px"> <el-radio label="1" :disabled="isReady" ></el-radio> </li> <li style="margin:10px 0 10px 20px"> <el-radio label="0" :disabled="isReady" ></el-radio> </li> </ul> </el-radio-group> </el-card> </div> </div> </el-main> </el-container> </el-container> </div>

    下面的截图是实现后哦的样式

    下面是使用的样式

     js可以参考这进行动态交互,这个是一次提交完成的,你们也可以做一道题提交一次,这样退出后进来还可以接着考试
