我正在寻找一种好的算法来获取一个数组中的所有元素，而不是另一个数组中的元素。所以给定这些数组：

var x = ["a","b","c","t"];
var ​​​​​​​​​y = [​​​​​​​"d","a","t","e","g"];

我想结束此数组：

var z = ["d","e","g"];

我正在使用jquery，因此可以利用$.each()and的优势$.inArray()。这是我想出的解决方案，但似乎应该有一个更好的方法。

// goal is to get rid of values in y if they exist in x
var x = ["a","b","c","t"];
var y = ["d","a","t","e","g"];

var z = [];
$.each(y, function(idx, value){
  if ($.inArray(value,x) == -1) {
    z.push(value);
  }
});
​alert(z);  // should be ["d","e","g"]

这是运行中的代码。有任何想法吗？
