Sorting Array Changes Keys?
Jan 26, 2010
Firstly, apologies for my terrible JavaScript knowledge! I'm getting there! I have an array that is made up of the results of a few SQL queries. The queries return the record id and an integer. I need to sort the results of the queries by the integer. I am trying to store them in an array, using the record is as the key, then sorting the array. However, when I try to get the data out of the array, it has changed the key!
E.g.
Original results
[10605] = 141
[10744] = 116
[18835] = 166
[15304] = 166
[Code]...

I have an associative array like this:
arr[x1]=30; arr[x2]=20;arr[x3]=40;arr[x4]=10;
I want the sort function to sort keys in ascending order of the values
on the right hand side with the following result:
x4,x2,x1,x3

I am passing some equity option contract data from my PHP processing page to the UI. I am attempting to use the JSON response to populate a matrix. Along the far right column are the strike prices (22, 23, 24, 25, 26, etc) and along the top row are the expiration dates (Jun 2008, Jul 2008, Aug 2008, etc.). My struggle is how to match the option data to the correct strike and expiration date. An example of the JSON response is below:
Code:
{"calls":
[
{"row_id":119,"type":"call","expiration":"JUN 20, 2009","t1":22,"strike":"25.00","symbol":"JSAFE"},
{"row_id":127,"type":"call","expiration":"JUN 20, 2009","t1":22,"strike":"26.00","symbol":"JSAFI"},
[code]....
Would be a JSON returned object that has all the option prices for all the expirations as properties.

I am really hoping someone is willing to take the time to read this post and take a minute to take a look at my code. What is happening is there are some matches for a script I made and then an area for segments during an event. If you notice on the segment part of the form is that there is a dropdown that asks for where in the event that segment needs to go. With the Introduction or the different numbered matches. What I need to happen for a subArray I need it to take the introduction, all the matches, and all the segments and order them accordingly. With the introduction first, the matches in order based off there match number and then the segments in between the introduction or matches based off the user's input.[URL]..

Given a JavaScript "array" (ok, so really they are "objects" but it's being treated as an array...) in the format
HTML Code:
var patient_code = "0"
var header_id = "1";
var question_id = "1000";
fake_data_array["patients"][patient_code][header_id][question_id]
HTML Code:
var fake_data_array = new Array();
fake_data_array["heading_information"] = new Array();
[Code]...
What's happening is, '1000', '1001', '1003', '1004' are being cast as integers, not strings, and it's "filling in" the first ~999 keys as 'undefined' so the length is returning something like 1005, not 7. I'm manually writing the arrays now, and will eventually be building this massive js array from a collection of existing PHP arrays. Is there a way to forcibly cast the values as strings?

I would like to have an array and define which element goes to what key. Something like this:
Code:
var test = [][];
test[0][0] = "foo";
test[0][1] = "bar";
However I am wondering if its possible to write it in one statement? Something like this:
Code:
var test[0] = [
[0] => "foo",
[1] => "bar"
];
The code up doesn't work of course.

I'm trying to present a collapsible list if keys which when expanded will have a delete button at the end of it. My problem is that when this code runs, the confirmation alert shows the key name as the last one read from the array for all items. Here's the complete function:

why this code invokes the deleteNote function with the last key name for all notes?

in PHP I can create a multi-dimensional array with strings for keys,eg
$arr['key'] = array("item 1","item 2");
This works if the string is a variable as well, like
$key = "MyKey";
$arr[$key] = array("item 1","item 2");
I'm trying to something similar in javascript, but with no luck

I am trying to setup a textbox to only accept specific keys. The problem is, some of the Function keys are reading as the same values as letters.Ex.
112 - F1 - p
113 - F2 - q
114 - F3 - r[code]....
Is there another way to allow the function keys without enabling all matching letters as well?

For example if I have this function name: function sortScores(myscores){ I would like to take an array of score records (each containing a score and a page number) and return a sorted version where the records are arranged in descending order of score.
so if I have this example call: sortScores( [ { score:0, Number:0 }, { score:2, Number:1 }, { score:1, NUmber:2 } ] )
I would get the example result:[ { score:2, Number:1 }, { score:1, Number:2 }, { score:0, Number:0 } ]
Where the results have been sorts in descending order of score. I've looked at this example, but it only deals with one one value -->[URL]..

I am declaring a 2D array like this...
Code:
var myArray = [];
myArray[0] = [];
myArray[1] = [];
So now the first dimension will have a size of two (0 or 1) and the second dimension will have an unlimited size. I want to sort this array by the integer values held in myArray[1][x], where x is any number between zero and the size of my result set. That is, I want to reorder the array such that

I am making a php/mysql epos system for my shop which will be run from a browser on my shop PC. I have large buttons which I would like to be able to 'click' by pressing something like the F-buttons at the top of the keyboard. Is it possible to override the standard button shortcuts for a web page. This is only going to be on my shop computer so accessibility is not a problem.

Say I have two arrays with the same number of elements that are related:
var a1 = [1,3,2];
var b2 = ["a","b","c"];
I need to sort a1 but have the order of the elements in b2 reflect the
any new order in a1. So if a1 sorts as
[1,2,3] then b2 becomes
["a","c","b"]
or if a1 sorts as
[3,2,1] then b2 becomes
["b","c","a"]

I have written this program:
var scores=[];
function sortScores(scoreRecs){
for(i=0;i<scoreRecs.length;i++)
[code]...
to take an array of variables in calling the function (ie sortScores), place these variables into an empty array("scores"), apply the bubble sort to scores, and then alert scores in sorted form. When I use test values like I have above, where they are all just numbers, this program works perfectly and alerts the "scores" array, correctly sorted. However, what I would like to do is to call the function with an array of records, each containing two fields, and apply the same sort to the array of records, based on the value in the first field of each record.To illustrate, i'd like to be able to call the function thus:
sortScores([{score:0,index:0},{score:2, index:1},{score:1,index:2}]);
and for it to sort the records in descending order of the value of the "score" field. So the above call would alert:
[{score:2,index:1},{score:1,index:2},{score:0,index:0}]
however, i'm not sure how i'd reference the numeric part of the f1 of each record in the sort?

I'm writing some stuff where I wish to allow the cursor keys to control
elements in a page. This has not been a problem except with Safari
which appears to duplicate the keydown and keyup events which are fired
when the cursor keys are pressed. I.e. pressing and releasing say, K,
results in one keydown event followed by one keyup event. Press any of
the cursor keys results in two keydown events followed by two keyup
events.....

Does anybody know why doesn't onkeypress catch up/down arrow keys
while it catches left/right arrows? My only supposition is that up/
down keys are used for moving between form elements, anyway does
anybody know any solution to this problem?

I have a little problem that i hope can be solved. You start to type in an <input> field and a list of results show based on what you type, I have a list of Airports in MySQL that is check for LIKE of what is typed in and the matches show that can be selected. But you can only scroll with the mouse and not the arrow keys.
Does anyone know how I may allow arrow keys as well as the mouse to select their choice?
