javascript - Angularjs 从数组中删除项目的方法

Question

如何让 playerinit 从 emptyseats 中删除使用的座位？假设 seatid 为 1，那么它将从 emptyseats 中删除 seat: 1?

   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

    };

使用原生 Array#filter 函数:

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});

    };
