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;
};
}
