試下這樣，a,b,c,d是多選項(xiàng)的值，改為你的多選項(xiàng)的值
{eyou:diyfield type='checkbox' id='diy' name='$eyou.field.diy'}
{eyou:if condition="($diy.value== 'a')"}
<span class='style1'>我是1</span>
{eyou:elseif condition="($diy.value== 'b')"}
<span class='style2'>我是2</span>
{eyou:elseif condition="($diy.value== 'c')"}
<span class='style3'>我是3</span>
{eyou:elseif condition="($diy.value== 'd')"}
<span class='style4'>我是4</span>
{/eyou:if}
