elment ui 中el-input标签中@input初始化赋值触发问题

遇见问题记录起来，方便以后隔了很久再次遇到。

elment ui 中el-input标签中@input初始化赋值时会触发到@input方法

  <el-input-number
    v-model="scope.row.discount_value"
    :controls="false"
    :min="0"
    :precision="0"
    @input="setDiscount_value(scope.row, scope.$index)"
    size="mini"
    :max="productDiscount.activity_type === 'DIRECT_DISCOUNT' ? 100 : Infinity"></el-input-number>

把@input方法 改成 @change

  <el-input-number
    v-model="scope.row.discount_value"
    :controls="false"
    :min="0"
    :precision="0"
    @change="setDiscount_value(scope.row, scope.$index)"
    size="mini"
    :max="productDiscount.activity_type === 'DIRECT_DISCOUNT' ? 100 : Infinity"></el-input-number>
