1.不可以输入负数:min="0" 但是可以输入保留2位小数
<el-input
:disabled="goodManageForm.freightType !== 0"
:min="0"
placeholder="请输入"
type="number"
oninput=" value=value.indexOf('.') > -1?value.slice(0, value.indexOf('.') + 3):value"
v-model="goodManageForm.freightFee"
style="width:30%"
class="price-desc"
clearable
>
2.去掉:上下箭头
参考: blog.csdn.net/louting249/…
//全局去除input的type为number时的上下箭头
::v-deep input::-webkit-outer-spin-button,
::v-deep input::-webkit-inner-spin-button { -webkit-appearance: none; }
::v-deep input[type="number"]{ -moz-appearance: textfield; }
