velocity-字母序号 list

版权声明：本文为博主原创文章，未经博主允许不得转载。

【需求】

遍历一个list，同时需要在每个item前面显示字母序号，例如A,B,C,D

【代码】

1. #set($zimu = ["A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z"])
2. #set($k=0)
3. #foreach($item in ${questionDTO.answerList})
4. <span class="exe_mc_option" data-obid="${item.obid}">
5. <span class="optionid">$zimu.get($k)</span>${item.answerContext}
6. </span>
7. #set($k=$k+1)
8. #end

【说明】
这里定义了一个k，如果使用$zimu.get($velocityCount-1)这种形式会报错，没有深究原因。
