        for(var i=0;i<this.length;i++){
            var temp = this[i];
            if(!isNaN(obj)){
                temp=i;
            }
            if(temp == obj){
                for(var j=i ;j<length;j++){
                    this[j] = this[J+1];
                }
                this.length = this.length-1 ;
            }
