VisualizaçõesVue.js error: TypeError: Cannot read properties of undefined
My knowledge of vue.js is limited but as far as i'm aware this should work, for some reason when I try to access my variable in the data property it can't find it.
data: function() {
return {
id: 0,
clients: []
}
},
methods: {
getClientData(){
fetch('/view-clients/' + this.id).then(function (response) {
return response.text();
}).then(function (data) {
this.clients = JSON.parse(data);
this.id = this.clients[clients.length - 1].id;
}).catch(function (error) {
console.log('Error: ' + error);
});
}
}

Function scope is most likely the culprit. Use arrow functions instead so this refers to the Vue component.
data() {
return {
id: 0,
clients: []
}
},
methods: {
getClientData(){
fetch('/view-clients/' + this.id).then((response) => response.text())
.then((data) => {
this.clients = JSON.parse(data);
this.id = this.clients[this.clients.length - 1].id;
}).catch((error) => {
console.log('Error: ' + error);
});
}
}
