<el-form :model="changePassword" ref="ruleForm" label-width="100px">
                <el-form-item label="新密码：" prop="password">
                    <el-input
                        @input.native="onInput($event, 'newPassword')"
                        type="text"
                        v-model="newPassword"
                        maxlength="12"
                        placeholder="6-12位字符，支持数字、大小写英文" >
                    </el-input>
                </el-form-item>
                <el-form-item label="重复新密码：" prop="repeatPassword">
                    <el-input
                        @input.native="onInput($event, 'repeatPassword')"
                        type="text"
                        maxlength="12"
                        v-model="repeatPassword"
                        placeholder="再次输入登录密码">
                    </el-input>
                </el-form-item>
            </el-form>

js代码

data () {
        return {
            verifyData: {},
            changePassword: {
                step: 1,
                type: 'message',
                tel: '',
                verifyCode: '',
                password: '',
                newPassword: '',
                repeatPassword: ''
            },
            password: '',
            newPassword: '',
            repeatPassword: ''
        }
    },
      methods: {
        // 监听输入
        onInput (e, type) {
            if (e.data) {
                if (this.changePassword[type].length < 12) {
                    this.changePassword[type] += e.data
                    setTimeout(() => {
                        this[type] = this[type].replace(/./g, '*')
                    }, 700)
                }
            } else {
                if (this.changePassword[type].length > 0) {
                    this.changePassword[type] = this.changePassword[type].substring(0, this.changePassword[type].length - 1)
                }
            }
        }
       }

**也可以使用下面这种**

// 监听输入
    onInput (e, type) { 
        if (e.data) { 
            if (this.changePassword[type].length < 12) { 
                this.changePassword[type] += e.data
            }
        } else { 
            if (this.changePassword[type].length > 0) { 
                this.changePassword[type] = this.changePassword[type].substring(0, this.changePassword[type].length - 1)
            }
        }
    },
    onKeyUp (type) { 
        this[type] = this[type].replace(/./g, '*')
    },
