JavaScript对象数组的排序处理方法

<script language=javascript>
 var myArray = new Array();
 for(var i=0;i<10;i++ ){
 myArray[i]=new Array();
 myArray[i][0]=Math.floor(Math.random()10); 
 myArray[i][1]=Math.floor(Math.random()10);
 myArray[i][2]=Math.floor(Math.random()10);
 myArray[i][3]=Math.floor(Math.random()10);
 myArray[i][4]=Math.floor(Math.random()10);
 myArray[i][5]=Math.floor(Math.random()10);
 myArray[i][6]=Math.floor(Math.random()10);
 myArray[i][7]=Math.floor(Math.random()10);
 myArray[i][8]=Math.floor(Math.random()10);
 }
 myArray.sort(
   function(x, y) {
    if(x[4]!=y[4]){
      return x[4]-y[4];
    } else if(x[8]!=y[8]){
      return x[8]-y[8];
    } else if(x[6]!=y[6]){
      return x[6]-y[6];
    } else {
      return 1;
    }
  }
  );
 for(var i=0;i<myArray.length;i++ )...{
 document.write(myArray[i].join(",") + "<br/>");
 }
</script>

function sortFunction(array) {
 return array.sort( function(x, y) ...{
 return (x[0]==y[0])?(x[1].localeCompare(y[1])):(x[0].localeCompare(y[0]))
 });
}
