vue公共按钮实现

Vue 公共按钮组件的实现方法

封装基础按钮组件

创建一个可复用的基础按钮组件，通常放在 src/components 目录下。示例代码：

<template>
  <button 
    :class="['base-button', type, size, { 'disabled': disabled }]"
    :disabled="disabled"
    @click="handleClick"
  >
    <slot></slot>
  </button>
</template>

<script>
export default {
  name: 'BaseButton',
  props: {
    type: {
      type: String,
      default: 'default',
      validator: value => ['default', 'primary', 'danger', 'warning'].includes(value)
    },
    size: {
      type: String,
      default: 'medium',
      validator: value => ['small', 'medium', 'large'].includes(value)
    },
    disabled: {
      type: Boolean,
      default: false
    }
  },
  methods: {
    handleClick(e) {
      this.$emit('click', e)
    }
  }
}
</script>

<style scoped>
.base-button {
  border-radius: 4px;
  cursor: pointer;
  transition: all 0.3s;
}

.primary {
  background-color: #1890ff;
  color: white;
}

.danger {
  background-color: #ff4d4f;
  color: white;
}

.small {
  padding: 4px 8px;
  font-size: 12px;
}

.large {
  padding: 10px 16px;
  font-size: 16px;
}

.disabled {
  opacity: 0.6;
  cursor: not-allowed;
}
</style>

全局注册组件

在 main.js 中全局注册组件，方便在整个项目中使用：

import Vue from 'vue'
import BaseButton from '@/components/BaseButton.vue'

Vue.component('BaseButton', BaseButton)

使用动态插槽和图标

增强按钮组件的灵活性，支持图标和动态内容：

<template>
  <button class="base-button" :class="[type, size]">
    <span v-if="$slots.icon" class="icon-wrapper">
      <slot name="icon"></slot>
    </span>
    <slot></slot>
  </button>
</template>

<style scoped>
.icon-wrapper {
  display: inline-flex;
  align-items: center;
  margin-right: 4px;
}
</style>

实现按钮权限控制

结合项目权限系统，添加权限验证功能：

<script>
export default {
  props: {
    permission: {
      type: String,
      default: ''
    }
  },
  computed: {
    hasPermission() {
      return !this.permission || this.$store.getters.hasPermission(this.permission)
    }
  }
}
</script>

<template>
  <button v-if="hasPermission" class="base-button">
    <slot></slot>
  </button>
</template>

集成Loading状态

添加异步操作时的Loading状态反馈：

<template>
  <button 
    class="base-button"
    :disabled="loading"
  >
    <span v-if="loading" class="loading-spinner"></span>
    <slot v-else></slot>
  </button>
</template>

<script>
export default {
  props: {
    loading: {
      type: Boolean,
      default: false
    }
  }
}
</script>

<style scoped>
.loading-spinner {
  display: inline-block;
  width: 14px;
  height: 14px;
  border: 2px solid rgba(255,255,255,0.3);
  border-radius: 50%;
  border-top-color: white;
  animation: spin 1s ease-in-out infinite;
}

@keyframes spin {
  to { transform: rotate(360deg); }
}
</style>

主题定制方案

通过CSS变量实现主题定制：

<style scoped>
.base-button {
  --primary-color: #1890ff;
  --danger-color: #ff4d4f;
  --warning-color: #faad14;
}

.primary {
  background-color: var(--primary-color);
}

.danger {
  background-color: var(--danger-color);
}

.warning {
  background-color: var(--warning-color);
}
</style>
