NodeJS：发送套接字但没有回调

Question

当info.password1和info.password2不相同时，我发送一个套接字：

if(info.password1 != info.password2) {
    socket.emit('registerError', {value: 'passwordNotTheSame'});
    console.log("Register errors");
}

在客户端：

socket.on('registerError', function(error) {
    console.log("error!");
});

但是当我发送套接字用于注册而不是相同的密码它不会工作时，它应该显示在控制台日志中'错误！'：

完整代码： server.js：

socket.on('requestRegister', function(info) {
    if(!info.username || !info.password1 || !info.password2 || !info.email) {
        socket.emit("rebuild", {value: true});
        socket.emit('startChatInfo', { rooms: rooms, users: users });
        return;
    }

    var checks = ['username', 'password1', 'password2', 'email'];
    var check = [];
    for(var i = 0; i < checks.length; i++) {
        if(checks[i].trim() == "") {
            check.push(checks[i]);
        }
    }

    if(check.length != 0) {
        for(var index = 0; index < check.length; index++) {
            socket.emit('registerError', {value: check[i]});
            var indexOf = check.indexOf(check[index]);
            if(indexOf > -1) {
                check.splice(indexOf, 1);
            }
        }
    } else {
        if(info.password1 != info.password2) {
            socket.emit('registerError', {value: 'passwordNotTheSame'});
            console.log("Register errors");
        } else if(!validateEmail(info.email)) {
            socket.emit('registerError', {value: 'emailNotValid'});
        } else {
            mysql.query("SELECT COUNT(username) as founds FROM users WHERE username = "+mysql.escape(info.username)+" LIMIT 1", function(result) {
                if(result[0].founds == 0) {
                    mysql.query("INSERT INTO users(username, password, email, ip_registed, ip_last) VALUES ("+mysql.escape(info.username)+", "+mysql.escape(info.password)+", "+mysql.escape(info.email)+", "+address.address+", "+address.address+" )", function(err) {
                        socket.emit('requestLogin', {username: info.username, password: info.password});
                    });
                } else {
                    socket.emit('registerError', {value: 'usernameFull'});
                }
            });
        }
    }
});

客户端：

function register() {
    var checks = ['#inputUsernamer', '#inputPasswordr1', '#inputPasswordr2', '#inputEmailr'];
    var shakes = [];
    for(var i = 0; i < checks.length; i++) {
        if($( ""+checks[i]+"" ).val().trim() == "") {
            shakes.push(checks[i]);
        }
    }

    for(var index = 0; index < shakes.length; index++) {
        $( ""+shakes[index]+"" ).effect( "shake" );
        var indexOf = shakes.indexOf(shakes[index]);
        if(indexOf > -1) {
            shakes.splice(indexOf, 1);
        }
    }

    if(shakes.length == 0) {
        if($("#inputPasswordr1" ).val() != $( "#inputPasswordr1" ).val()) {
            alert("De wachtwoorden komen niet overeen!");
        } else if(!validateEmail($( "#inputEmailr" ).val())){
            alert("Het email adres is niet geldig!");
        } else {
            socket.emit("requestRegister", {
                username: $( "#inputUsernamer" ).val(),
                password1: $( "#inputPasswordr1" ).val(),
                password2: $( "#inputPasswordr2" ).val(),
                email: $( "#inputEmailr" ).val()
            });
        }
    }

    socket.on('registerError', function(error) {
        console.log("error!");
    });
}
