基于jQuery的试卷自动排版系统实现代码


Posted in Javascript onJanuary 06, 2011

根据提供的试卷题目(是一个干净的只有“数据”的HTML网页)生成一份多页的试卷,用户能执行翻页、具有答题时间限制,展示给用户的试卷中题目需要占用尽量少的空间(比如选择题中把两条较短的选项由两行合并到一行)、同一道题目不要跨页面显示以方便答题者,管理员能够改变试卷的样式(字体、颜色、行距、页面边距,像字处理软件一样……),题目之间可以插入一些说明性的文字(比如告知答题者作答的须知等等)。题目提干、选择题的选项、说明文字可以包含多媒体信息(文字、图片、列表、表格、视频等等……)。选择题选项数目不限、单选多选不限。翻页要有可订制的动画效果

提供的试卷样板类似如下(Input):

<ol id="olThePaper"> 
<div class="Desc">选择题:说明文字。说明文字。说明文字。说明文字。说明文字。说明文字。说明文字。说明文字。说明文字。说明文字。说明文字。说明文字。说明文字。说明文字。</div>

<label><input type="radio" name="prob1" value="B" />所在教学班的成绩优于其他平行班</label> 
<label><input type="radio" name="prob1" value="C" />严格管理学生、所带的班级班风良好</label> 
<label><input type="radio" name="prob1" value="D" />父母般地关心学生的生活和情绪状态</label> 
</div> 
</div> 
<div class="Problem" id="2"> 
<li>2.一位有15年教龄的英语教师,教了多年高三,可谓学校的核心骨干。一次接受邀请到外校介绍教学经验,台下有老师发表了观点并问到几个英语教法发面的问题,一下子把她给卡住了。这是因为</li>

思路
面对这种需求该怎么办呢?使用JavaScript了,看来。后来决定用jQuery,Aptana作IDE(虽然jQuery支持库在Windows上死活装不上去,换了个OS就好了,奇怪),格式么就用CSS了。

具体步骤:

导入试卷题目HTML
对所有选择题进行排版,把一行划分为四个位置,使选项尽量适应一个位置、两个位置或四个位置(也就是一行四项、一行两项或者一行一项的效果)
对所有题目进行分页
思路还是清晰的,但是由于浏览器众多,还是比较麻烦的,并且我是新手,没接触过jQuery之前……

实现
