31、cookie小test

请尽量使用JQuery进行代码编写,需求如下:

 

 

1.  页面初始化样式如图

 

 

2. 顶部input框中输入内容,按下回车enter键后,“正在进行” 列表中加入该条内容。

 

 

3. 顶部input框中输入内容,按下回车enter键后,“正在进行” 列表中继续加入内容。右上角的数字跟随列表数目变化而变化。

 

 

4. 点击列表左侧checkbox,可以将“正在进行”的列表项变更为“已经完成”的列表项。每个列表中的数字要跟随变动。

 

 

5. 点击列表项右侧的删除按钮可以删除列表项。

 

 

6. 将当前列表项内容保存在cookie中,做持久存储,下一次访问页面的时候,仍可以看到以前的列表项内容。

 

7. 要求样式布局尽量和图片上保持一致
