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

基于vue与element实现创建试卷相关功能(实例代码)

首先是试卷的相关设置

考试对象是通过接口返回的数据

基于vue与element实现创建试卷相关功能(实例代码)

<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

基于vue与element实现创建试卷相关功能(实例代码)

<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

基于vue与element实现创建试卷相关功能(实例代码)
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 "
   >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 "
   >
    <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
这个在之前一篇博客中简单介绍过,感兴趣的朋友可以自行前去了解

最最后把create.vue的源码分享给大家方便大家进行参考,如有更好的建议也请大家不吝赐教

暂无基于vue与element实现创建试卷相关功能(实例代码)的评论...

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!

昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。

这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。

而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
