JavaScript實用函數：移除陣列元素 (Java script function: remove element from Array )

function array_removeAt(array,index)
  {
   var newArr=new Array(array.length-1);
   
   var idx=0;
   for(var i=0;i<array.length-1;i++)
    {
     if(i==index)continue;
     
     newArr[idx]=array[i];
     idx++;
    }
   return newArr;   
  }
