array sort by value - easy?

[podenphant]

hi there,

I pulling data from a DB split it into to array and now I would like to sort it depending on a specific value.

myArr[0] = ["nameA",0,"mail"]
myArr[1] = ["nameB",2,"mail"]
myArr[2] = ["nameC",1,"mail"]
myArr[3] = ["nameD1",1,"mail"]
myArr[4] = ["nameE",0,"mail"]
myArr[5] = ["nameF",2,"mail"]

I would like to sort the array depending on the second value.
All values of '1' should go first. Followed by all values of '0' and then all values of '2'.

To make it look like this
myArr[0] = ["nameC",1,"mail"]
myArr[1] = ["nameD",1,"mail"]
myArr[2] = ["nameA",0,"mail"]
myArr[3] = ["nameE",0,"mail"]
myArr[4] = ["nameB",2,"mail"]
myArr[5] = ["nameF",2,"mail"]

Am I making myself understandable?

Looks like it's possible with sortOn(), but you'd have to enter the array elements as objects instead of arrays.

From the help files on sortOn() method of arrays:

This following example creates a new array and sorts it based on the field city:

var recArray = new Array();
recArray.push( { name: "bob", city: "omaha", zip: 68144 } );
recArray.push( { name: "greg", city: "kansas city", zip: 72345 } );
recArray.push( { name: "chris", city: "burlingame", zip: 94010 } );
recArray.sortOn("city");
// results in the following:
recArray[0] = name: "chris", city: "burlingame", zip: 94010
recArray[1] = name: "greg", city: "kansas city", zip: 72345
recArray[2] = name: "bob", city: "omaha", zip: 68144


Maybe this helps?

Try this....

myArr = new Array();
myArr[0] = ["nameA",0,"mail"];
myArr[1] = ["nameB",2,"mail"];
myArr[2] = ["nameC",1,"mail"];
myArr[3] = ["nameD1",1,"mail"];
myArr[4] = ["nameE",0,"mail"];
myArr[5] = ["nameF",2,"mail"];

// Storing the order in array (first 1, then 0, then 2)
var theOrder = new Array(1, 0, 2);
// Storing an increment value for use with theOrder
var whichElement = 0;

// Declaring array that store newly sorted array values.
var newMyArr = new Array();
// Increment for use with newMyArr
var elementIncrement = 0;

// Looping though all patterns from theOrder
for (var j=0;j<=theOrder.length;j++) {

// Looping though all the elements of myArr
for (var i=0;i<myArr.length;i++) {

// If the 1 element of myArr[i] matches the first pattern(theOrder[0])
// Add that elements elements to the new array (newMyArr)
// then increment elementIncrement ready to write newMyArr
//next element
if (myArr[i][1]==theOrder[whichElement]) {
newMyArr[elementIncrement] = [myArr[i][0], myArr[i][1], myArr[i][2]];
elementIncrement++;
}
}

// If there is no match, increment whichElement, (to start looking //for the next pattern (theOrder[1]), etc)
whichElement++;
}
// Re-assign the value of myArr with newly contructed array newMyVar

myArr = newMyArr;
// Cleaning up temp variables.....
delete newMyArr;
delete whichElement;
delete theOrder;
