How can I make the playerinit remove the seat used from emptyseats?
lets say seatid is 1, then it will remove seat: 1 from emptyseats?
vm.emptyseats = [
{seat: 1},
{seat: 2},
{seat: 3},
{seat: 4},
{seat: 5},
{seat: 6},
{seat: 7},
{seat: 8},
{seat: 9},
];
vm.playerinit = function(x) {
console.log("init user data");
var seatid = x.position;
// vm.emptyseats remove where seat: seatid
};
Using native Array#filter function:
vm.playerinit = function(x) {
console.log("init user data");
var seatid = x.position;
// vm.emptyseats remove where seat: seatid
//Using ES6 arrow function syntax
vm.emptyseats = vm.emptyseats.filter( (empty_seat) => empty_seat.seat !== seatid);
//Or regular syntax
vm.emptyseats = vm.emptyseats.filter( function(empty_seat) { return empty_seat.seat !== seatid});
};
Array.filter() is IE9+. Still a good answer, though.Array#push method. Example: vm.emptyseat.push({seat: 3})First, you need to find the index of the array you want to remove. Then, use Array.splice():
var seatid = x.position;
angular.forEach(vm.emptyseats, function(emptyseat, i) {
if(emptyseat.seat !== seatid) return;
vm.emptyseats.splice(i, 1);
});
A native JS approach, IE 9+
vm.emptyseats = vm.emptyseats.filter(function(a) { return a.seat != seatid; });
You can remove it with a simple for loop:
for(var i = 0; i < emptyseats.length; i++) {
if(vm.emptyseats[i].seat == seatid) vm.emptyseats.splice(i, 1);
}
With your full code:
vm.playerinit = function(x) {
console.log("init user data");
var seatid = x.position;
// vm.emptyseats remove where seat: seatid
for(var i = 0; i < emptyseats.length; i++) {
if(vm.emptyseats[i].seat == seatid) {
vm.emptyseats.splice(i, 1);
console.log(seatid + " removed!");
}
}
};
Try using .splice() to do this.
vm.emptyseats.splice(0,1);
