vue检查用户名是否重复

1.vue检查用户名是否重复

  • 前端函数如下,js方法代码无需更改,前端代码逻辑在components\common\lab_header.vue

  • 只需要修改components\axios_api\http.js中调用的后端地址

// axios.defaults.baseURL = "http://127.0.0.1:8000/"
axios.defaults.baseURL = "http://192.168.56.100:8888/"
</template>
 <div>      
     <input
       type="username"
       name="username"
       class="form-control"
       v-model="username"
      @blur="check_username"
      placeholder="请输入用户名">
 </div>
</template>

<script>
    // 检查用户名 是否使用
   methods: {
    check_username() {
      console.log('判断用户名')
      console.log(this.username == '')
      var reg = new RegExp(/^[a-zA-Z0-9_-]{3,16}$/); //字符串正则表达式 4到14位(字母,数字,下划线,减号)
      if (this.username == '') {
        this.username_message = '用户名不能为空'
        this.username_error = true
        return false
      }
      if (!reg.test(this.username)) {
        this.username_message = '用户名格式不正确'
        this.username_error = true
        return false
      } else {
        // 去后端检查用户名使用数量
        user_count({ type: 'username', data: this.username }).then((res) => {
          console.log(res)
          if (res.data.count > 0) {
            this.username_message = '用户名已存在'
            this.username_error = true
          } else {
            this.username_message = ''
            this.username_error = false
          }
        })
      }
    },
}
</script>

2.vue检查手机号是否重复

<template>
  <div>
    <input
    name="phone"
    class="form-control"
    v-model="phone"
    placeholder="请输入手机号"
    @blur="check_phone">
  </div>
</template>

<script>
    // 检查手机号是否使用
   methods: {
    check_phone() {
      console.log('检查手机号')
      var reg = new RegExp(/^[1]([3-9])[0-9]{9}$/)
      if (this.phone == '') {
        this.phone_message = '手机号不能为空'
        this.phone_error = true
      }

      if (!reg.test(this.phone)) {
        this.phone_message = '手机号格式不正确'
        this.phone_error = true
        return false
      } else {
        // 去后端查用户数量
        user_count({ type: 'phone', data: this.phone }).then((res) => {
          console.log(res)
          if (res.data.count > 0) {
            this.phone_message = '手机号已存在'
            this.phone_error = true
          } else {
            this.phone_message = ''
            this.phone_error = false
          }
        })
      }
    },
}
</script>
