var app = new Vue({

},
methods: {
change: function () {
this.show = false;
setTimeout("", 5000);
this.show = true;
}
}
});
</script>

Why does the element not hide for 5 seconds after pressing the button and then show again? And how can I change the code to achieve this function?

Answer
This directly sets show to true:
console.log(false);
setTimeout(() => console.log("done"), 5000);
console.log(true);setTimeout takes a function to be executed after the timeout, this is where you need to change the variable:
new Vue({
el: "#app",
data: { show: true },
methods: {
change: function () {
this.show = false;
setTimeout(() => this.show = true, 5000);
}
}
