element-UI中el-form带有检验功能，用法如下：

<template>
    <div>
        <el-form size="small" ref="userform" :rules="rulesForm" :model="form">
            <el-form-item label="用户名" prop="userName">
                <el-input v-model.trim="form.userName"  :disabled="addUserDialogTitle == '编辑用户'"></el-input>
            </el-form-item>
            <el-form-item label="联系方式" prop="phone">
                <el-input v-model.number="form.phone"></el-input>
            </el-form-item>
            <el-form-item>
                <el-button type="primary" @click="onSubmit">立即创建</el-button>
            </el-form-item>
        </el-form>
    </div>
</template>
<script>
import { checkSpecialKey,validateInputPhone } from '@/api/check'
export default {
    name: 'userList',
    data () {
        let validateInputSpecialKey = (rule, value, callback) => {
            if (!checkSpecialKey(value)) {
                callback(new Error("不能含有特殊字符！！"));
            } else {
                callback();
            }
        };
        let validateInputPhone = (rule, value, callback) => {
            if (!checkPhone(value)) {
                callback(new Error("请正确输入联系方式！！"));
            } else {
                callback();
            }
        };
        return {
            form：{},
            rulesForm: {//弹窗输入框检验
                userName: [
                  { required: true,message: "请输入用户名",trigger: "blur"},
                  { min: 3,max: 10,message: "长度在 3 - 10 字符" },
                  { validator: validateInputSpecialKey, trigger: "blur" }
                ],
                phone:[
                  { required: true,message: "请输入联系方式",trigger: "blur"},
                  { validator: validateInputPhone, trigger: "blur" }
                ]
            }
        }
    },
    methods:{
        //提交表单
        onSubmit(){
            this.$refs['userform'].validate((valid) => {
                if (valid) {
                    //TODO 调用接口提交数据
                }else{
                    return false
                }
            })
        }
    }
}
</script>

校验方法有：

校验是否包含特殊字符

export function checkSpecialKey(str) {
    let specialKey =
    "[`~!#$^&*()=|{}':;'\\[\\].<>/?~！#￥……&*（）——|{}【】‘；：”“'。，、？]‘'";
    for (let i = 0; i < str.length; i++) {
        if (specialKey.indexOf(str.substr(i, 1)) != -1) {
        return false;
        }
    }
    return true;
}

校验是否包含特殊字符(路径专用)

export function checkSpecialKeyPath(str) {
    let specialKey =
    "[`~!#$^&*()=|{}';'<>?~！#￥……&*（）——|{}【】‘；”“'。，、？]‘'";
    for (let i = 0; i < str.length; i++) {
        if (specialKey.indexOf(str.substr(i, 1)) != -1) {
        return false;
        }
    }
    return true;
}

校验是否包含中文

export function checkChinese(val) {
    // 正则匹配非中英文及数字的字符
    let reg = /[\u4e00-\u9fa5]/;
    let n = reg.test(val);
    if ( n ) {
        return false
    }
    return true
}

校验是否手机号码或者固话

export function checkPhone(val) {
    let reg = /^((0\d{2,3}-\d{7,8})|(1[34578]\d{9}))$/;
    let n = reg.test(val);
    if ( !n ) {
        return false
    }
    return true
}

校验密码是否合格

export function checkPassword(val) {
    let reg = /^(?![\d]+$)(?![a-zA-Z]+$)(?![^\da-zA-Z]+$)([^\u4e00-\u9fa5\s]){6,20}$/;
    let n = reg.test(val);
    if ( !n ) {
        return false
    }
    return true
}

校验非负浮点数

export function checkNumberNotNegative(val) {
    let reg = /^\d+(\.\d+)?$/;
    let n = reg.test(val);
    if ( !n ) {
        return false
    }
    return true
}
