未设置前

光标在左边

<input type="number" placeholder="请输入分润数量" placeholder-class="shareprofit_placeholder_num"
v-model="money">

设置后

光标在右边

<input type="number" placeholder="请输入分润数量" placeholder-class="shareprofit_placeholder_num"
v-model="money" style="text-align: right; direction: rtl;">

要设置input样式

在input加上这两个样式就ok了

.identity-input {
  text-align: right;
  direction: rtl;
}
