由于最近在一个项目中需要实现创建试卷与预览试卷的功能，所以就自己动手写了一个，效果还不错，目前项目已经交付使用，今天就先和大家分享一下创建试卷。
创建试卷
先放一下效果图
首先是试卷的相关设置
考试对象是通过接口返回的数据
<span class="content-label">选择考试对象</span> <el-form-item prop="roleList"> <el-select v-model="form.roleList" multiple filterable allow-create default-first-option placeholder="请选择考试对象" > <el-option v-for="item in roles" :key="item.value" :label="item.label" :value="item.value" /> </el-select> </el-form-item>
需要定义的data数据
roles: [], //考试对象选择列表（接口返回）
form: {
title: '',
roleList: [], // 考试对象
deadline: '', // 截止时间
questions: []
},
获取考试对象列表
getRoles() {
crudRoles.getAll().then(res => {
res.map((obj) => {
const role = {
value: obj.id,
label: obj.name
}
this.roles.push(role)
})
})
},
截至时间使用的是element时间日期选择器
<span class="content-label">截止时间</span> <el-form-item prop="deadline"> <el-date-picker v-model="form.deadline" type="datetime" placeholder="选择日期时间" value-format="yyyy-MM-dd HH:mm:ss" /> </el-form-item>
然后是添加试题
试题类型的相关数据也是通过接口返回的
data数据
questionType: [],
获取试题类型
getQuestionType() {
crudExam.getQuestionType().then(res => {
this.questionType = res
})
},
<div class="question-type">
<el-button
v-for="item in questionType"
:key="item.typeId"
style="border-color: #2A82E4; color: #2A82E4"
@click="addQuestion(item.typeId)"
>
<svg-icon :icon-class="item.icon" />
{{ item.typeName }}
</el-button>
</div>
addQuestion(typeId) {
const question = {
id: this.questionId,
quesTypeId: typeId,
title: '',
score: 0,
answer: [],
content: []
}
this.form.questions.push(question)
this.questionId++
},
对于添加的试题模板则是单独创建了一个question.vue
这里由于其他布局方法一直不太理想，所以采用了栅格布局，效果还算可以
<template>
<el-card class="box-card">
<div slot="header" class="clearfix" style="margin-bottom: -10px">
<span
class="type-name"
v-text="question.quesTypeId < 3 ?
question.quesTypeId === 1 ?
'单选题' : '多选题'
: question.quesTypeId < 5 ?
question.quesTypeId === 3 ?
'填空题' : '简答题'
: '判断题'"
>卡片名称</span>
<el-input v-model="question.score" style="width: 55px" />
<span>分</span>
<el-button style="float: right; border: none; font-size: 20px" icon="el-icon-close" @click="removeQuestion" />
</div>
<el-form-item>
<el-input
v-model="question.title"
type="textarea"
placeholder="请输入题干内容..."
/>
</el-form-item>
<!--单选、多选-->
<el-form-item v-if="question.quesTypeId === 1 || question.quesTypeId === 2" style="margin-bottom: 0px">
<el-checkbox-group
v-model="question.answer"
:min="0"
:max="question.quesTypeId === 1 ? 1 : 4"
>
<el-row
v-for="(item, index) in ['A', 'B', 'C', 'D']"
:key="item"
>
<el-col :span="1">
<el-checkbox-button
v-model="question.answer"
:label="question.content[index]"
border
>
{{ item }}
</el-checkbox-button>
</el-col>
<el-col :span="23">
<el-input
v-model="question.content[index]"
placeholder="请输入选项..."
@input="contentChange(question)"
/>
</el-col>
</el-row>
</el-checkbox-group>
</el-form-item>
<!--简答、填空-->
<el-form-item v-if="question.quesTypeId === 3 || question.quesTypeId === 4" style="margin-bottom: 0px">
<el-input
v-model="question.answer[0]"
type="textarea"
placeholder="请输入参考答案"
/>
</el-form-item>
<!--判断-->
<el-form-item v-if="question.quesTypeId === 5" style="margin-bottom: 0px">
<el-checkbox-group
v-model="question.answer"
:min="0"
:max="1"
>
<el-checkbox v-model="question.answer" label="对" border />
<el-checkbox v-model="question.answer" label="错" border />
</el-checkbox-group>
</el-form-item>
</el-card>
</template>
<script>
export default {
props: {
question: {
type: Object,
required: true
}
},
methods: {
removeQuestion() {
this.$emit('removeQuestion', this.question.id)
},
contentChange(question) {
question.answer.splice(0)
}
}
}
</script>
<style scoped>
.type-name {
color: #505050;
margin-right: 20px;
}
</style>
然后是删除试题
<question v-for="item in form.questions" :key="item.id" :question="item" class="question-content" @removeQuestion="removeQuestion" />
removeQuestion(id) {
for (let i = 0; i < this.form.questions.length; i++) {
if (this.form.questions[i].id === id) {
this.form.questions.splice(i, 1)
}
}
},
最后提交方法中进行数据验证
