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>
