关于饿了么ui里面的表单校验规则

页面有两个输入框 想要写一个校验规则 校验这两个输入框的只能输入1-99之间的数字 并且这两个输入框中填的数字相加不能大于100

 <el-col :span="6">
            <el-form-item
              class="form-item"
              v-if="
                ruleForm.payMode[0] == 'YHZZ' || ruleForm.payMode[1] == 'YHZZ'
              "
              label="银行转账比例(%)："
              prop="arbAdditionInfo.yhzzPercentage"
            >
              <el-input
                class="payinput-width"
                v-model="ruleForm.arbAdditionInfo.yhzzPercentage"
                size="mini"
              ></el-input>
            </el-form-item>
          </el-col>
          <el-col :span="6">
            <el-form-item
              class="form-item form-item-width"
              v-if="
                ruleForm.payMode[0] == 'CDHP' || ruleForm.payMode[1] == 'CDHP'
              "
              label="承兑汇票比例(%)："
              prop="arbAdditionInfo.cdhpPercentage"
            >
              <el-input
                class="payinput-width"
                v-model="ruleForm.arbAdditionInfo.cdhpPercentage"
                size="mini"
              ></el-input>
            </el-form-item>
          </el-col>




下面是现在写的校验规则  只写了一个 不知道要怎么添加 和判断
  var validatePercentage = (rule, value, callback) => {
      if (!value || isNaN(value) || value <= 0 || value >= 99) {
        return callback(new Error("百分之0-99"));
      } else {
        callback();
      }
    };

需要改的地方自己改改

<template>
  <div>
    <el-form
      :model="ruleForm"
      :rules="rules"
      ref="ruleForm"
      label-width="100px"
      class="demo-ruleForm"
    >
      <el-form-item label="价格" prop="price">
        <el-input v-model="ruleForm.price"></el-input>
      </el-form-item>
      <el-form-item label="价格2" prop="price2">
        <el-input v-model="ruleForm.price2"></el-input>
      </el-form-item>
    </el-form>
  </div>
</template>
<script>
export default {
  data() {
    let validatePass = (rule, value, callback) => {
      if (!value) {
        callback(new Error("请输入价格"));
      } else {
        if (Number(value) + Number(this.ruleForm.price2) > 100) {
          callback(new Error("不能大于100"));
        }
        callback();
      }
    };
    let validatePass2 = (rule, value, callback) => {
      if (!value) {
        callback(new Error("请输入价格"));
      } else {
        if (Number(value) + Number(this.ruleForm.price) > 100) {
          callback(new Error("不能大于100"));
        }
        callback();
      }
    };
    return {
      ruleForm: {
        price: "",
        price2: "",
      },
      rules: {
        price: [{ validator: validatePass, trigger: "blur" }],
        price2: [{ validator: validatePass2, trigger: "blur" }],
      },
    };
  },
  methods: {},
};
</script>

可以写一个监听器，当两个值相加超过100就提示错误
