login(){
    this.$refs.loginFormRef.validate(  valid =>{
        console.log(valid);
        if (!valid) return;
        const result=  this.$axios.post("login/loginCheckOut",this.loginForm);
        console.log(result);
    });
}

login(){
    this.$refs.loginFormRef.validate( async valid =>{
        console.log(valid);
        if (!valid) return;
        const result= await this.$axios.post("login/loginCheckOut",this.loginForm);
        console.log(result);
    });
}

login(){
    this.$refs.loginFormRef.validate( async valid =>{
        console.log(valid);
        if (!valid) return;
        const {data:res}= await this.$axios.post("login/loginCheckOut",this.loginForm);
        console.log(res);
