实现 Enter 键登录功能

在 Vue 中实现 Enter 键登录功能可以通过监听键盘事件来完成。以下是几种常见的实现方式：

方法一：在输入框上监听 keyup.enter 事件

<template>
  <div>
    <input v-model="username" placeholder="用户名" @keyup.enter="handleLogin" />
    <input v-model="password" placeholder="密码" type="password" @keyup.enter="handleLogin" />
    <button @click="handleLogin">登录</button>
  </div>
</template>

<script>
export default {
  data() {
    return {
      username: '',
      password: ''
    }
  },
  methods: {
    handleLogin() {
      // 登录逻辑
      console.log('登录:', this.username, this.password)
    }
  }
}
</script>

方法二：在表单上监听 submit 事件

<template>
  <form @submit.prevent="handleLogin">
    <input v-model="username" placeholder="用户名" />
    <input v-model="password" placeholder="密码" type="password" />
    <button type="submit">登录</button>
  </form>
</template>

<script>
export default {
  data() {
    return {
      username: '',
      password: ''
    }
  },
  methods: {
    handleLogin() {
      // 登录逻辑
      console.log('登录:', this.username, this.password)
    }
  }
}
</script>

方法三：在 mounted 钩子中监听全局键盘事件

<template>
  <div>
    <input v-model="username" placeholder="用户名" ref="usernameInput" />
    <input v-model="password" placeholder="密码" type="password" ref="passwordInput" />
    <button @click="handleLogin">登录</button>
  </div>
</template>

<script>
export default {
  data() {
    return {
      username: '',
      password: ''
    }
  },
  mounted() {
    window.addEventListener('keyup', this.handleKeyUp)
  },
  beforeDestroy() {
    window.removeEventListener('keyup', this.handleKeyUp)
  },
  methods: {
    handleKeyUp(event) {
      if (event.key === 'Enter') {
        this.handleLogin()
      }
    },
    handleLogin() {
      // 登录逻辑
      console.log('登录:', this.username, this.password)
    }
  }
}
</script>
