Why Does My Code Return [object Object]?

[Guest]

I want it to return what I enter in the text boxes but the price, size, and username all have to remain paired up. The data also needs to remained stored so the next time someone comes and enters in their own data the previous data isn't deleted. Later on I want to be able to sort columns by Price, by Size, and by Username. So why does it keep returning [object Object] with anything I enter? Thank you so much for any help you can give me!!

var wheat:Array = new Array()

var priceS:String

var price:int

var sizeS:String

var size:int

var username:String

submit_btn.addEventListener(MouseEvent.CLICK, wheatBidSubmit);

function wheatBidSubmit(event:MouseEvent):void

{   

    priceS = (price_txt.text)

    price = int(priceS)

    sizeS = (size_txt.text)

    size = int(sizeS)

    username = (username_txt.text)

    wheat.push({Price:price, Size:size, Username:username})

    trace (wheat)

}

that's expected.

to inspect an array of objects, use:

function traceF(a:Array):void{

for(var i:int=0;i<a.length;i++){

for(var s:String in a){

trace(i,s,a);

}

}

}

How do I access one of the items, say Price for example. I want to see just what the Price is. What you gave me works great, but it shows me all three components

[kglad · Accepted solution]

use:

function traceF(a:Array):void{

for(var i:int=0;i<a.length;i++){

trace(i,a.price);

}

}

(p.s when using the adobe forums, please mark helpful/correct responses, if there are any.)

So I have a 2 column DataGrid with Price in the left column and Size in the right column. How do I sort it so that it sorts Price in ascending order but Size in descending order? Like this...

$1.00     2

$2.00     4

$2.00     3

[kglad]

like this:

wheat.sort(sortF);

function sortF(a:Object,b:Object):int{

if(numberF(a.price)<numberF(b.price)){

return -1;

} else if(numberF(a.price)>numberF(b.price)){

return 1;

} else if(numberF(a.price)==numberF(b.price)){

if(a.size<b.size){

return -1;

} else if(a.size>b.size){

return 1;

} else {

return 0;

}

}

}

function numberF(price):Number{

//convert your price into a number and return it.  i'm not sure if your price is a string like $1.00 or something else

}

[Guest]

What is "numberF" in this example?

[Guest]

Oh oh oh!!! I see it now! Thank you sooo very much, you are absolutely amazing! If I could help you I would but with this stuff your miles ahead. Thanks  so much, I'm sure I'm not finished with all my questions yet

[kglad]

you're welcome.

If I have two arrays, one for bid prices and one for sell prices, how do I tell the computer to check and see when the price of one matches the price of the other at any point and then get rid of that price. As with before there is also "Size" and "Username" within each array element so they will have to be removed as well. So you could enter $2, $3, $4, $3 to the bid array and $6, $5, $1, $4 to the sell array and the computer sorts it perfectly thanks to your advice earlier. But now how to I get it to remove a $4 from both arrays because it shows up on both sides?

[kglad]

you can use the splice() method to remove an array element.  eg, to remove the ith element

wheat.splice(i,1)

Hey again! Hopefully you still follow this question because I've got another problem. So right now I have two arrays that consist of a Price, Size, and Username in each element. One array is for buying (Bids) and the other is for selling (Ask). When data gets entered, it is displayed in two datagrids, one for Bids, one for Asks. But what I need now is a way to check and see if the same price has been entered on both sides of the table. So if $10.00 is entered on a Bid and $10.00 is entered on an Ask. If the prices are the same I need to delete that row on both the Bid side and the Ask side. What is giving me problems is that I can delete elements no problem, but if there are only 3 elements on the Bid side and say 2 elements on the ask side, I can't get the computer to "search". Plus! In the future I want this to happen. If there are prices that are the same the next thing is to look at Sizes. If the prices and the sizes are the same, the whole element is to be deleted. But if say there is an Ask for $10.00, Size 10, and a Bid for $10.00, Size 5, I need the bid to be removed and the ask to go to $10.00, Size 5. Just subtracting the original Ask size from the Bid size. Good luck, you're my only hope right now. I'll send you my code so you're not stabbing in the dark. If there's anything I can do for you, let me know, thanks!

that's getting a bit more involved than i do for free.  if you can narrow your question, i'll answer it here.

but i won't go through more than 20-30 lines of code and lengthy questions that require more than a minute or two to understand, unless i'm hired.

[Guest]

Totally understand! So say I have two arrays, ArrayOne and ArrayTwo. In each element there is a Price and a Size. All I'm concerned about is Price. So say I enter $10, $30, $20 into ArrayOne (in that order). The computer sorts it like you taught me. And then someone enters $40, $20 into ArrayTwo. computer sorts it. How can I make it so that the computer looks at the two arrays and determines if there is a point where the same price appears in both arrays and deletes them. So in this case it would delete the element with $20 in ArrayOne and ArrayTwo

[kglad]

// sellBidF will remove one matched price in both arrays and return an array of two objects removed: the matched bid object and the matched ask object

function bidSellF(bidA:Array,askA:array):Array{

for(var i:int=bidA.length-1;i>=0;i--){

for(var j:int=askA.length-1;j>=0;j--){

if(bidA.price==askA.price){

return [bid.splice(i,1),askA.splice(j,1)];

}

}

}

}
