actually i'm trying to call the function demandConnexion after an event, but it is working for me , it telles me that "this.demandeConnexion is not a function" . how can i get it to work ? help , this is the code :
Serveur.prototype.demandConnexion = function(idZEP) {
if (this.ZP.createZE(idZEP))
{
console.log(' ==> socket : demande de creation ZE pour '+idZEP +' accepte');
}
else
{
console.log(' ==> socket : demande de creation ZE pour '+idZEP +' refuse');
}
};
Serveur.prototype.traitementSurConnection = function(socket) {
// console.log('connexion');
console.log(' ==> socket connexion');
// traitement de l'evenement DEMANDE DE CONNEXION D'UNE ZE
socket.on('connection', (function(idZEP) { this.demandConnexion(idZEP)
console.log('good')
}))
It's because when the callback is called "this" isn't your "Serveur" instance. In your case try something like
var that = this;
socket.on('connection', (function(idZEP) {
that.demandConnexion(idZEP)
console.log('good')
}))or
socket.on('connection', this.demandConnexion.bind(this));An other solution (the best in my opinion) would be to use the arrow functions to keep the same scope as the closure
socket.on('connection', ()=>{
//here this refers to your Serveur (the enclosing scope)
});
