下面是一个基于 Uniapp 的油耗计算器实现，包含 Vue 组件和页面代码。

1. 创建页面文件

在 pages 目录下创建 fuel-calculator 页面：

<!-- pages/fuel-calculator/fuel-calculator.vue -->
<template>
  <view class="container">
    <view class="calculator">
      <view class="header">
        <text class="title">油耗计算器</text>
      </view>
      
      <view class="input-group">
        <text class="label">当前油价 (元/升)</text>
        <input 
          type="number" 
          v-model="price" 
          placeholder="例如：7.85" 
          class="input"
          @input="validateInput('price')"
        />
      </view>
      
      <view class="input-group">
        <text class="label">加油金额 (元)</text>
        <input 
          type="number" 
          v-model="money" 
          placeholder="例如：300" 
          class="input"
          @input="validateInput('money')"
        />
      </view>
      
      <view class="input-group">
        <text class="label">行驶里程 (公里)</text>
        <input 
          type="number" 
          v-model="distance" 
          placeholder="例如：450" 
          class="input"
          @input="validateInput('distance')"
        />
      </view>
      
      <button class="calculate-btn" @click="calculate">计算油耗</button>
      
      <view class="result" v-if="showResult">
        <view class="result-header">
          <text class="result-title">计算结果</text>
        </view>
        <view class="result-item">
          <text>加油量:</text>
          <text class="result-value">{{ fuel.toFixed(2) }} 升</text>
        </view>
        <view class="result-item">
          <text>百公里油耗:</text>
          <text class="result-value">{{ consumption.toFixed(2) }} 升/百公里</text>
        </view>
        <view class="result-item">
          <text>每公里油费:</text>
          <text class="result-value">{{ costPerKm.toFixed(2) }} 元</text>
        </view>
      </view>
    </view>
  </view>
</template>

<script>
export default {
  data() {
    return {
      price: '',
      money: '',
      distance: '',
      fuel: 0,
      consumption: 0,
      costPerKm: 0,
      showResult: false
    }
  },
  methods: {
    validateInput(field) {
      // 确保输入是正数
      if (this[field] < 0) {
        this[field] = ''
      }
    },
    calculate() {
      // 验证输入
      if (!this.price || !this.money || !this.distance) {
        uni.showToast({
          title: '请填写完整信息',
          icon: 'none'
        })
        return
      }
      
      if (this.price <= 0 || this.money <= 0 || this.distance <= 0) {
        uni.showToast({
          title: '请输入大于0的数值',
          icon: 'none'
        })
        return
      }
      
      // 计算
      this.fuel = this.money / this.price
      this.consumption = (this.fuel / this.distance) * 100
      this.costPerKm = this.money / this.distance
      
      this.showResult = true
      
      // 隐藏键盘
      uni.hideKeyboard()
    }
  }
}
</script>

<style>
.container {
  padding: 20px;
  background-color: #f5f5f5;
  min-height: 100vh;
}

.calculator {
  background-color: #ffffff;
  border-radius: 10px;
  padding: 20px;
  box-shadow: 0 2px 10px rgba(0, 0, 0, 0.1);

  text-align: center;
  display: block;
}

.input-group {
  margin-bottom: 20px;
}

2. 配置页面路由

在 pages.json 中添加页面路由配置：

{
  "pages": [
    // ...其他页面配置
    {
      "path": "pages/fuel-calculator/fuel-calculator",
      "style": {
        "navigationBarTitleText": "油耗计算器"
      }
    }
  ]
}
