Remove duplicate object values in array

[JTreefrog]

Hello - I've read a ton of stuff about deleting duplicate values in an array. They are all very useful - they just haven't addressed an array of objects.

Here's my array:
[HTML]
var sDat = [{
sid:12,
scode:"code",
sname:"Sam"
},
{
sid:12,
scode:"code",
sname:"Sam"
},
{
sid:139,
scode:"code",
sname:"Jake"
}];
[/HTML]
The array is produced from JSON sent to me from a database query. I can't do a "group by" in the sql query - i actually need the repeats in a different array.

Anyway - I want to be able to remove duplicate sDat.sid entries in my sDat array - but I'm having difficulties discovering a way to handle it.

Any ideas?

hi ...

for such tasks we may use something like the following example:

[CODE=javascript]var sDat = [
{ sid:12, scode:"code", sname:"Sam" },
{ sid:12, scode:"code", sname:"Sam" },
{ sid:139, scode:"code", sname:"Jake"}
];

function cleanup(arr, prop) {
var new_arr = [];
var lookup = {};

for (var i in arr) {
lookup[arr[i][prop]] = arr[i];
}

for (i in lookup) {
new_arr.push(lo okup[i]);
}

return new_arr;
}

var n = cleanup(sDat, 'sid');
[/CODE]
that makes use of javascript objects and the for-in loop construct ...

kind regards
