好家伙，本篇将继续完善前端界面

 

效果展示:

1.注册登陆

(后端已启动)

 

 

 

 

2.注册表单验证

(前端实现的表单验证)

 

 

 

 

在此之前:

我的第一个项目(二)：使用Vue做一个登录注册界面 - 养肥胖虎 - 博客园 (cnblogs.com)

后端部分:

我的第一个项目(三)：注册登陆功能(后端) - 养肥胖虎 - 博客园 (cnblogs.com)

 

1.前端发送网络请求(axios)

请求部分:

{
                //发起网络请求,
                this.axios.post('http://localhost:3312/sys-user/register', this.ruleForm).then((resp) => {
                    console.log(resp);
                    
                    let data = resp.data;
                    console.log(data);
                    //检验注册是否成功
                    if (data.success) {
                        //清空表单数据
                        this.ruleForm = {};
                        //发送成功通知
                        this.$message({
                            message: '恭喜你,注册成功,点击去登陆按钮进行登陆吧!!!',
                            type: 'success'
                        });
                    }
                })
                this.$router.push({ path: '/login' })
            }

 

2.表单验证:

if (this.ruleForm.password != this.ruleForm.checkPass) {
                this.$message({
                    message: '两次输入密码不一致!!!',
                    type: 'error'
                });
            }
            else if(this.ruleForm.loginName==""){
                this.$message({
                    message: '请输入账户!!!',
                    type: 'error'
                });
            }
            else if(this.ruleForm.name==""){
                this.$message({
                    message: '请输入昵称!!!',
                    type: 'error'
                });
            }
            else if(this.ruleForm.password==""){
                this.$message({
                    message: '请输入密码!!!',
                    type: 'error'
                });
            }

这个没什么好解释的,就是很简单的验证

如果使用的是组件的表单(比如:element之类的)也可以编辑相应的表单验证方法(规则)

当然,自己手写也没什么问题

 

 

补充:数据库建表

(前面好像一直都忘了)
