javascript中数组中删除阵列 [英] javascript remove array from array

问题描述

假设我们有以下的数组：

Assume we have the following arrays:

a = [1, 2, 3, 4, 5]

和

b = [2, 3]

我怎样才能从减去B？所以，我们有 C = A - B 这应该是等于 [1，4，5] 。 jQuery的解决方案也将被罚款。

How can I subtract b from a? So that we have c = a - b which should be equal to [1, 4, 5]. jQuery solution would also be fine.

推荐答案

假设你在有<一个浏览器href=\"https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Array/filter\"><$c$c>Array.prototype.filter和<一个href=\"https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Array/indexOf\"><$c$c>Array.prototype.indexOf,你可以使用这样的：

Assuming you're on a browser that has Array.prototype.filter and Array.prototype.indexOf, you could use this:

var c = a.filter(function(item) {
    return b.indexOf(item) === -1;
});

如果有问题的浏览器没有这些方法，您可能能够垫片它们。

If the browser in question does not have those methods, you may be able to shim them.
