【问题描述】：
我有预定义的范围值作为选择元素的选项，范围可以从任何负值到预定义的正值（我正在使用 select2 插件）。
例如 -12 到 +12 以定义的增量说 0.25 在这种情况下我如何让选项值始终从 0 开始。
<select id="form_exam:currentLenses:rCylinder" name="form[exam:currentLenses:rCylinder]" class="select-2 form-control select2-hidden-accessible" data-select2-id="form_exam:currentLenses:rCylinder" tabindex="-1" aria-hidden="true">

值 0 实际上很重要，所以我不能只默认为零
