6
<Input
  v-model.number="addForm.categoryorder"
  :number="true"
  type="number"
  placeholder="请输入排序"
></Input>

这种方式有个问题就是可以输入e，导致保存失败。

方式2

这里我们只让输入正整数。

我们自己处理输入的内容，只保留里面的数字。

<Input
  v-model.number="addForm.categoryorder"
  :number="true"
  @keyup.native="inputUpNumber"
  type="text"
  placeholder="请输入排序"
></Input>

这里使用的是text类型，使用number类型输入1e的时候是获取不到内容的。

  if (!reg.test(value)) {
    let numArr = value.match(/[0-9]+/g);
    if (numArr && numArr.length > 0) {
      e.target.value = numArr[0];
    } else {
      e.target.value = "";
    }
  }
