I'm fetching all the contacts from the device using the code from phonegap api (http://docs.phonegap.com/en/3.3.0/cordova_contacts_contacts.md.html)
I'm trying to work out how to sort the contacts alphabetically. There are some questions already on here about it but they don't have full and comprehensive answers.
Can anyone help?
Thanks
try this
var cSort = function(a, b)
{
aName = a.lastName + ' ' + a.firstName;
bName = b.lastName + ' ' + b.firstName;
return aName < bName ? -1 : (aName == bName ? 0 : 1);
};
function contactSuccess(contacts) {
contacts = contacts.sort(cSort);
...
};
The cSort function needs to reference the correct object (eg a.name.familyName), like this:
function onSuccess(contacts) {
var cSort = function(a, b) {
aName = a.name.familyName + ' ' + a.name.givenName;
bName = b.name.familyName + ' ' + a.name.givenName;
return aName < bName ? -1 : (aName == bName ? 0 : 1);
};
contacts = contacts.sort(cSort);
for (var i = 0; i < contacts.length; i++) {
var contact = contacts[i];
$scope.phoneContacts.push(contact);
}
};
This is an efficient method (that i'm using).
1. contact.name.formatted property is rather more reliable.
2. The contacts names are grouped together, irregardless of the letter's case
var cSort=function(a,b){
var an=a.name.formatted.toUpperCase();
var bn=b.name.formatted.toUpperCase();
return (an<bn)?-1:(an==bn)?0:1;
};
function contactSuccess(contacts) {
contacts = contacts.sort(cSort);
...
};

I want to compare my list of stocks price with my set Stoploss which is stored and once the condition trigger alert by email. Below is my code
function emailAlert()
{
var stock1nameRange = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Watchlist").getRange("A5");
var stock1name = stock1nameRange.getValues();
var stock1cmpRange = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Watchlist").getRange("B5");
var stock1cmp = stock1cmpRange.getValues();
var stock1s1Range = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Watchlist").getRange("AK5");
var s1 = stock1s1Range.getValues();
var stock1s2Range = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Watchlist").getRange("AL5");
var s2 = stock1s2Range.getValues();
var ui = SpreadsheetApp.getUi();
if(stock1cmp<s1)
{
if(stock1cmp<s2)
{
ui.alert( stock1name + stock1cmp + 'is less than' +s2 );
var message = stock1name + stock1cmp + 'is less than' +s2 ;
MailApp.sendEmail("#gmail.com", "Stock Watchlist alert", message)
return s2
}
else
{
ui.alert( stock1name + stock1cmp + 'is less than' +s1 );
var message = stock1name + stock1cmp + 'is less than' +s1 ;
MailApp.sendEmail("#gmail.com", "Stock Watchlist alert", message )
return s1
}
}
}
This is for single stock. How can I make it more generic and compile all the stock list which pass the condition into single mail. Thanks.

In order to be able to select all the values you will be needing a for loop.
Snippet
function emailAlert() {
var ui = SpreadsheetApp.getUi();
var sheet = SpreadsheetApp.getActive().getSheetByName("Watchlist");
var stockName = sheet.getRange("A5:FINAL_RANGE").getValues();
var stockCmp = sheet.getRange("B5:FINAL_RANGE").getValues();
var s1 = sheet.getRange("AK5:FINAL_RANGE").getValues();
var s2 = sheet.getRange("AL5:FINAL_RANGE").getValues();
for (var i = 0; i < stockName.length; i++) {
if (stockCmp[i][0] < s1[i][0]) {
if (stockCmp[i][0] < s2[i][0]) {
ui.alert(stockName[i][0] + stockCmp[i][0] + ' is less than ' + s2[i][0]);
var message = stockName[i][0] + stockCmp[i][0] + ' is less than ' + s2[i][0];
MailApp.sendEmail("#gmail.com", "Stock Watchlist Alert", message);
return s2[i][0];
} else {
ui.alert(stockName[i][0] + stockCmp[i][0] + ' is less than ' + s1[i][0]);
var message = stockName[i][0] + stockCmp[i][0] + ' is less than ' + s1[i][0];
MailApp.sendEmail("#gmail.com", "Stock Watchlist Alert", message);
return s1[i][0];
}
}
}
}
Explanation
The above code loops through all the values from your columns by using a for loop and then based on the conditions you set, is sending the email and alerting the user. The range is retrieved by using the getRange() method with the a1Notation parameter. The a1Notation parameter here is represented by the start and the end of the range in which you have the values you need for the script.
Note
The above script is built considering the fact that the stockName, stockCmp, s1, s2 are all associated, meaning that they all have the same number of values stored in them.
Reference
Apps Script Range Class - getValues();
Apps Script Sheet Class - getRange(a1Notation);

GAS is quite powerful and you could write a full fledged web-app using a Google Sheet as the DB back-end. There are many reasons not to do this but I figure in some cases it is okay.
I think the biggest issue will be performance issues when looking for rows based on some criteria in a sheet with a lot of rows. I know there are many ways to "query" a sheet but I can't find reliable information on which is the fastest.
One of the complexities is that many people can edit a sheet which means there are a variable number of situations you'd have to account for. For the sake of simplicity, I want to assume the sheet:
Is locked down so only one person can see it
The first column has the row number (=row())
The most basic query is finding a row where a specific column equals some value.
Which method would be the fastest?
I have a sheet with ~19k rows and ~38 columns, filled with all sorts of unsorted real-world data. That is almost 700k rows so I figured it would be a good sheet to time a few methods and see which is the fastest.
method 1: get sheet as a 2D array then go through each row
method 2: get sheet as a 2D array, sort it, then using a binary search algorithm to find the row
method 3: make a UrlFetch call to Google visualization query and don't provide last row
method 4: make a UrlFetch call to Google visualization query and provide last row
Here are the my query functions.
function method1(spreadsheetID, sheetName, columnIndex, query)
{
// get the sheet values excluding header,
var rowValues = SpreadsheetApp.openById(spreadsheetID).getSheetByName(sheetName).getSheetValues(2, 1, -1, -1);
// loop through each row
for(var i = 0, numRows = rowValues.length; i < numRows; ++i)
{
// return it if found
if(rowValues[i][columnIndex] == query) return rowValues[i]
}
return false;
}
function method2(spreadsheetID, sheetName, columnIndex, query)
{
// get the sheet values excluding header
var rowValues = SpreadsheetApp.openById(spreadsheetID).getSheetByName(sheetName).getSheetValues(2, 1, -1, -1);
// sort it
rowValues.sort(function(a, b){
if(a[columnIndex] < b[columnIndex]) return -1;
if(a[columnIndex] > b[columnIndex]) return 1;
return 0;
});
// search using binary search
var foundRow = matrixBinarySearch(rowValues, columnIndex, query, 0, rowValues.length - 1);
// return if found
if(foundRow != -1)
{
return rowValues[foundRow];
}
return false;
}
function method3(spreadsheetID, sheetName, queryColumnLetterStart, queryColumnLetterEnd, queryColumnLetterSearch, query)
{
// SQL like query
myQuery = "SELECT * WHERE " + queryColumnLetterSearch + " = '" + query + "'";
// the query URL
// don't provide last row in range selection
var qvizURL = 'https://docs.google.com/spreadsheets/d/' + spreadsheetID + '/gviz/tq?tqx=out:json&headers=1&sheet=' + sheetName + '&range=' + queryColumnLetterStart + ":" + queryColumnLetterEnd + '&tq=' + encodeURIComponent(myQuery);
// fetch the data
var ret = UrlFetchApp.fetch(qvizURL, {headers: {Authorization: 'Bearer ' + ScriptApp.getOAuthToken()}}).getContentText();
// remove some crap from the return string
return JSON.parse(ret.replace("/*O_o*/", "").replace("google.visualization.Query.setResponse(", "").slice(0, -2));
}
function method4(spreadsheetID, sheetName, queryColumnLetterStart, queryColumnLetterEnd, queryColumnLetterSearch, query)
{
// find the last row in the sheet
var lastRow = SpreadsheetApp.openById(spreadsheetID).getSheetByName(sheetName).getLastRow();
// SQL like query
myQuery = "SELECT * WHERE " + queryColumnLetterSearch + " = '" + query + "'";
// the query URL
var qvizURL = 'https://docs.google.com/spreadsheets/d/' + spreadsheetID + '/gviz/tq?tqx=out:json&headers=1&sheet=' + sheetName + '&range=' + queryColumnLetterStart + "1:" + queryColumnLetterEnd + lastRow + '&tq=' + encodeURIComponent(myQuery);
// fetch the data
var ret = UrlFetchApp.fetch(qvizURL, {headers: {Authorization: 'Bearer ' + ScriptApp.getOAuthToken()}}).getContentText();
// remove some crap from the return string
return JSON.parse(ret.replace("/*O_o*/", "").replace("google.visualization.Query.setResponse(", "").slice(0, -2));
}
My binary search algorithm:
function matrixBinarySearch(matrix, columnIndex, query, firstIndex, lastIndex)
{
// find the value using binary search
// https://www.w3resource.com/javascript-exercises/javascript-array-exercise-18.php
// first make sure the query string is valid
// if it is less than the smallest value
// or larger than the largest value
// it is not valid
if(query < matrix[firstIndex][columnIndex] || query > matrix[lastIndex][columnIndex]) return -1;
// if its the first row
if(query == matrix[firstIndex][columnIndex]) return firstIndex;
// if its the last row
if(query == matrix[lastIndex][columnIndex]) return lastIndex;
// now start doing binary search
var middleIndex = Math.floor((lastIndex + firstIndex)/2);
while(matrix[middleIndex][columnIndex] != query && firstIndex < lastIndex)
{
if(query < matrix[middleIndex][columnIndex])
{
lastIndex = middleIndex - 1;
}
else if(query > matrix[middleIndex][columnIndex])
{
firstIndex = middleIndex + 1;
}
middleIndex = Math.floor((lastIndex + firstIndex)/2);
}
return matrix[middleIndex][columnIndex] == query ? middleIndex : -1;
}
This is the function I used to test them all:
// each time this function is called it will try one method
// the first time it is called it will try method1
// then method2, then method3, then method4
// after it does method4 it will start back at method1
// we will use script properties to save which method is next
// we also want to use the same query string for each batch so we'll save that in script properties too
function testIt()
{
// get the sheet where we're staving run times
var runTimesSheet = SpreadsheetApp.openById("...").getSheetByName("times");
// we want to see true speed tests and don't want server side caching so we a copy of our data sheet
// make a copy of our data sheet and get its ID
var tempSheetID = SpreadsheetApp.openById("...").copy("temp sheet").getId();
// get script properties
var scriptProperties = PropertiesService.getScriptProperties();
// the counter
var searchCounter = Number(scriptProperties.getProperty("searchCounter"));
// index of search list we want to query for
var searchListIndex = Number(scriptProperties.getProperty("searchListIndex"));
// if we're at 0 then we need to get the index of the query string
if(searchCounter == 0)
{
searchListIndex = Math.floor(Math.random() * searchList.length);
scriptProperties.setProperty("searchListIndex", searchListIndex);
}
// query string
var query = searchList[searchListIndex];
// save relevant data
var timerRow = ["method" + (searchCounter + 1), searchListIndex, query, 0, "", "", "", ""];
// run the appropriate method
switch(searchCounter)
{
case 0:
// start time
var start = (new Date()).getTime();
// run the query
var ret = method1(tempSheetID, "Extract", 1, query);
// end time
timerRow[3] = ((new Date()).getTime() - start) / 1000;
// if we found the row save its values in the timer output so we can confirm it was found
if(ret)
{
timerRow[4] = ret[0];
timerRow[5] = ret[1];
timerRow[6] = ret[2];
timerRow[7] = ret[3];
}
break;
case 1:
var start = (new Date()).getTime();
var ret = method2(tempSheetID, "Extract", 1, query);

I have a global variable searchList that is an array of various query strings -- some are in the sheet, some are not.
I ran testit on a trigger to run every minute. After 152 iterations I had 38 batches. Looking at the result, this is what I see for each method:
| Method | Minimum Seconds | Maximum Seconds | Average Seconds |
|---------|-----------------|-----------------|-----------------|
| method1 | 8.24 | 36.94 | 11.86 |
| method2 | 9.93 | 23.38 | 14.09 |
| method3 | 1.92 | 5.48 | 3.06 |
| method4 | 2.20 | 11.14 | 3.36 |
So it appears that, at least for my data-set, is using Google visualization query is the fastest.
I have created the three text type custom options and one dropdown type custom option. If i changed the select box value
"height * width" after this calculation, I want to set the calculated result in one input box
this all done in jQuery but now i want to set that value as custom option price
Magento.
Can you please help??
jQuery("#paper_size").on( "change", '#drop', function(){
var reg = jQuery('#paper_size').find("#drop").val();
var str = jQuery('#options_3_text').val();
var str1 = jQuery('#options_2_text').val();
var total = (str * str1 * 11) + 7;
var totalmts = (str * str1 * 3.53) + 7;
if (reg == '2') {
jQuery('#options_4_text').val(total);
}
else{
jQuery('#options_4_text').val(totalmts);
});
}
});
I guess this will work cause there was a Bracket mismatch in your code I found out after I copied the code to VS Code
jQuery("#paper_size").on("change", '#drop', function () {
var reg = jQuery('#paper_size').find("#drop").val();
var str = jQuery('#options_3_text').val();
var str1 = jQuery('#options_2_text').val();
var total = (str * str1 * 11) + 7;
var totalmts = (str * str1 * 3.53) + 7;
if (reg == '2') {
jQuery('#options_4_text').val(total);
}
else {
jQuery('#options_4_text').val(totalmts);
}});
I've written the script below, so Sheets automatically inserts a new row and copies a formula to that new row.
I've specified that I'd like for this function to run only if changes are made to Columns 2 or 4, but the script runs regardless of the Column number or whether e.oldValue === undefined or not.
Two questions:
1) What is wrong with my code that it is ignoring the Column number and the data validation?
2) If a value is given into a cell and erased, does that cell revert back to undefined or is its value now " "?
Here is a link to the sheet: https://docs.google.com/spreadsheets/d/1m58J7vg_xfkrxK_9pxPSHAlBYULXbqNIiF8H2-KVBgE/edit#gid=1496977189
Code:
function onEdit(e) {
var sheet = SpreadsheetApp.getActiveSheet();
var activeCell = sheet.getActiveCell();
var activeColumn = activeCell.getColumn();
var walkoutRange = sheet.getRange(7, 17, 1);
var walkoutFormula = walkoutRange.getFormulas();
Logger.log(walkoutFormula);
var newRange = sheet.getRange((activeCell.getRow() + 1), 17, 1)
if (sheet.getName() != "Form") {
if (activeColumn === 2 || 4) {
if (e.oldValue === undefined) {
sheet.insertRowAfter(activeCell.getRow());
newRange.setFormula(walkoutFormula);
}
}
}
};
There is an uncaught error in the following line:
if (activeColumn === 2 || 4) {
Should be:
if (activeColumn === 2 || activeColumn === 4) {
The conditional test:
activeColumn === 2 || 4
Is always returning true;
function test() {
var activeColumn = 9;
Logger.log('is it true: ' + Boolean(activeColumn === 2 || 4))//returns true
if (activeColumn === 2 || 4) {
Logger.log(Boolean(activeColumn === 2 || 4))
};
};
I am working on a game in Construct2 at the moment.
It is a HTML5 Javascript Engine.
I probably implement clay.io inside it.
My question however is about "Rooms"
Clay.io also helps with Rooms. However I am not sure If I will take that offer.
https://clay.io/docs/rooms
So when I want to limit the users per game to 10 for example. Would I then need to run two servers?
The socket.io server recives and returns data.. But would two games running with each 10 people not confuse the servers data? When person A on server A shoots some1, that this information could somehow end up on Person B on server B?
Or do the assigned ID's prevent this somehow?
Here is the Example Server that I want to upgrade for my needs:
var entities = [], count = 0;
var io = require("socket.io").listen(8099);
var INITIAL_X = 5;
var INITIAL_Y = 5;
var INITIAL_VEL_X = 0;
var INITIAL_VEL_Y = 0;
io.set('log level', 1);
io.sockets.on("connection", function (socket) {
var myNumber = count++;
//assign number
var mySelf = entities[myNumber] = [myNumber, INITIAL_X, INITIAL_Y, INITIAL_VEL_X, INITIAL_VEL_Y];
//Send the initial position and ID to connecting player
console.log(myNumber + ' sent: ' + 'I,' + mySelf[0] + ',' + mySelf[1] + ',' + mySelf[2]);
socket.send('I,' + mySelf[0] + ',' + mySelf[1] + ',' + mySelf[2]);
//Send to conencting client the current state of all the other players
for (var entity_idx = 0; entity_idx < entities.length; entity_idx++) {
//send initial update
if (entity_idx != myNumber) {
entity = entities[entity_idx];
if (typeof (entity) != "undefined" && entity != null) {
console.log(myNumber + ' sent: C for ' + entity_idx);
socket.send('C,' + entity[0] + ',' + entity[1] + ',' + entity[2]);
//send the client that just connected the position of all the other clients
}
}
}
//create new entity in all clients
socket.broadcast.emit("message",
'C,' + mySelf[0] + ',' + mySelf[1] + ',' + mySelf[2]);
socket.on("message", function (data) {
//if (myNumber == 0)
// console.log(myNumber + ' sent: ' +data);
var new_data = data.split(',');
if (new_data[0] == 'UM') {
mySelf[1] = new_data[1];
mySelf[2] = new_data[2];
mySelf[3] = new_data[3];
mySelf[4] = new_data[4];
//Update all the other clients about my update
socket.broadcast.emit("message",
'UM,' + mySelf[0] + ',' + mySelf[1] + ',' + mySelf[2] + ',' + mySelf[3] + ',' + mySelf[4]);
}
else if (new_data[0] == 'S') { // a s message
var shoot_info = [];
shoot_info[0] = new_data[1]; //ini x
shoot_info[1] = new_data[2]; //ini y
shoot_info[2] = new_data[3]; //degrees
//Update all the other clients about my update
socket.broadcast.emit("message",
'S,' + mySelf[0] + ',' + shoot_info[0] + ',' + shoot_info[1] + ',' + shoot_info[2]);
}
});
});
Socket.io has rooms that you can limit the broadcasts to, see: https://github.com/LearnBoost/socket.io/wiki/Rooms
Then rather than use socket.broadcast.emit you would use io.sockets.in('roomname').emit
A good way to mesh this with Clay.io is to have the room name be the room.id (in the Construct 2 plugin that's the RoomId expression). When the Clay.io room fills up (in C2 there's a condition for that), create the Socket.io room using that unique ID and put the players who "Rooms Filled" was just called for in that room.
I know it's a bit different since it's a game written in CoffeeScript instead of Construct 2, but we're using Clay.io rooms + Socket.io rooms in our Slime Volley game. Here is the code.
