如何从值中删除数组中的项目？

如果不允许添加到本机原型，则可以是全局函数或自定义对象的方法。它从数组中删除与任何参数匹配的所有项目。

Array.prototype.remove = function() { var what, a = arguments, L = a.length, ax; while (L && this.length) { what = a[--L]; while ((ax = this.indexOf(what)) !== -1) { this.splice(ax, 1); } } return this; };

var ary = ['three', 'seven', 'eleven'];

ary.remove('seven');

/* returned value: (Array) three,eleven */

为了使其成为全球性的

function removeA(arr) { var what, a = arguments, L = a.length, ax; while (L > 1 && arr.length) { what = a[--L]; while ((ax= arr.indexOf(what)) !== -1) { arr.splice(ax, 1); } } return arr; } var ary = ['three', 'seven', 'eleven']; removeA(ary, 'seven');

/* returned value: (Array) three,eleven */

并照顾IE8及以下版本-

if(!Array.prototype.indexOf) { Array.prototype.indexOf = function(what, i) { i = i || 0; var L = this.length; while (i < L) { if(this[i] === what) return i; ++i; } return -1; }; }
