非常常用的一段代码

 1 //数组移除指定对象或下标i
 2 Array.prototype.remove = function (obj) {
 3     for (var i = 0; i < this.length; i++) {
 4         var temp = this[i];
 5         if (!isNaN(obj)) {
 6             temp = i;
 7         }
 8         if (temp == obj) {
 9             for (var j = i; j < this.length; j++) {
10                 this[j] = this[j + 1];
11             }
12             this.length = this.length - 1;
13         }
14     }
15 }
