Sorting multidimensional array

1

I have an array of objects (the first member of each object is a string which records the object’s name) The other members of the objects contain various numerical information. I need to sort each category of information and display the names next to their related information in correct numerical order:
ie. AName 4235
AnotherOne 3962
OneMore 1576

Can anyone suggest some code which would do this? I checked out .sort and .onSort, built in methods of array but I can’t get my head round it.There are thirteen objects in my array. The fourth element (population) needs to be sorted. I tried
x=0;
for (i=0;i<14;i++) {//counts through objects in array
if ( EmpireList * [3] >x)
x= EmpireList * [3];//loops through array to find greatest numerical value
} //and writes it into x
LargestInArray = x;

This gave me the biggest numerical element in the array. I figured I needed some kind of nested for loop to find the next largest and so on but I can’t get it to work.

Ideally I need to copy the information into a new array with two dimensions (for name and information)

Thanks

arrays have various built-in sort functions. check them out in Flash help.

// simulation of your array of objects
ary = [{name:"sheep", id:101},
	 {name:"elephants", id:56},			 
	 {name:"aardvarks", id:300}];

// sort by the field 'id'
ary.sort( function(a,b) { return a.id - b.id; } );

// display the results
for (var i = 0; i < ary.length; ++i) {
	trace(ary*.id + ": " + ary*.name);
}

Output:

56: elephants
101: sheep
300: aardvarks

Note to admin: The [ as ] tag doesn’t handle indents very well…

Yep. That did the trick. Thanks a lot. C:-)
