我现在有个登陆的功能，管理员登录时会正常显示Notification 通知如下图：但是学生和教师登陆的时候会显示这样，如下图：还有的时候直接不显示，这是什么原因？userlogin() { var reg = /[\u4E00-\u9FA5]|[\uFE30-\uFFA0]/g; //匹配汉字 var ret = /^[a-zA-Z0-9]{6,}$/; //匹配数字和字母最少五次 if (this.form.account == "") { this.$notify.error({ title: "错误", message: "用户名不能为空", duration: 1500, }); } else { if (this.form.password == "") { this.$notify.error({ title: "错误", message: "密码不能为空", duration: 1500, }); } else { if (reg.test(this.form.account)) { this.$notify.error({ title: "错误", message: "用户名不能出现汉字", duration: 1500, }); } else { if (ret.test(this.form.account)) { if (ret.test(this.form.password)) { this.axios .login(this.form) .then((res) => { if (res.data.code == 202) { this.$notify.error({ title: "错误", message: res.data.msg, duration: 1500, }); }else if(res.data.code == 203){ this.$notify.success({ title: "正确", message: "登录成功", duration: 1500, }); console.log(res.data.data.role) if (res.data.data.role == 3) { //商城后台用户 window.location.href = "/student.html#/studentIndex"; //学生账号 this.$store.dispatch( "DataStorage/studentId", res.data.data.userTrain.id ); //实训id this.$store.dispatch( "DataStorage/trainId", res.data.data.trainId ); } else if (res.data.data.role == 1) { //管理员账号 window.location.href = "/index.html#/administrator"; this.$store.dispatch( "DataStorage/teacherId", res.data.data.id ); //管理员/教师id } else if (res.data.data.role == 2) { //教师账号 window.location.href = "/teacher.html#/"; this.$store.dispatch( "DataStorage/teacherId", res.data.data.id ); //教师id } } }) .catch((err) => {}); } else { this.$notify.error({ title: "错误", message: "密码不能少于6位", duration: 1500, }); } } else { this.$notify.error({ title: "错误", message: "用户名不能少于6位", duration: 1500, }); } } } } },
