Multidimensional array showing duplicate values

I'm adding values to a multidimensional array using loops
var leg_array = {};
var enc_array = [];
for (var c = 0; c < result.routes[0].legs.length; c++) {
leg_array[c] = {};
for (var b = 0; b < result.routes[0].legs[c].steps.length; b++) {
//var lat_lngs = result.routes[0].legs[c].steps[b].encoded_lat_lngs; //encoded polyline representation
var start_location_A = result.routes[0].legs[c].steps[b].start_location.A;
var start_location_F = result.routes[0].legs[c].steps[b].start_location.F;
var end_location_A = result.routes[0].legs[c].steps[b].end_location.A;
var end_location_F = result.routes[0].legs[c].steps[b].end_location.F;
enc_array[b] = start_location_A + "," + start_location_F + ":" + end_location_A + "," + end_location_F;
leg_array[c] = enc_array;
}
}
console.log(leg_array);
When i check the console log, the arrays in the first level of the multi dimensional array are identical.
How can i solve this? Values of enc_array are duplicate in every leg_array
e.g. leg_array[0] = enc_array, leg_array[1] = enc_array
enc_array is the same when the values should be different.

You are referencing the same array multiple times. If you want to create different arrays for each leg_array[c] value, use the Array.prototype.slice method instead:
leg_array[c] = enc_array.slice()
This will create a new copy of enc_array (in it's current form) to store in leg_array[c].
Of course, if you do that in the current location, it will set that same value multiple times (because it's inside the loop). Moving it to be inside the outer for loop will probably get the result you want.

Netsuite Javascript Grab Last Array Value

So I found some info on this site on how to go about grabbing the value of the last index of an array. I have an Array that is of an unknown length. It builds based on a search of results. For example:
var custid = nlapiGetFieldValue('entity');
var custRecord = nlapiLoadRecord('customer', custid);
var itemPriceLineCount = custRecord.getLineItemCount('itempricing');
for (var i = 1; i <= itemPriceLineCount; i++) {
var priceItemId = [];
priceItemId = custRecord.getLineItemValue('itempricing', 'item', i);
if (priceItemId == itemId) {
var histCol = [];
histCol[0] = new nlobjSearchColumn('entity');
histCol[1] = new nlobjSearchColumn('totalcostestimate');
histCol[2] = new nlobjSearchColumn('tranid');
histCol[3] = new nlobjSearchColumn('trandate');
var histFilter = [];
histFilter[0] = new nlobjSearchFilter('entity', null, 'is', custid);
histFilter[1] = new nlobjSearchFilter('item', null, 'is', itemId);
var histSearch = nlapiSearchRecord('invoice', null, histFilter, histCol);
for (var h = 0; h <= histSearch.length; h++) {
var itemRate = new Array();
var histSearchResult = histSearch[h];
itemRate = histSearchResult.getValue('totalcostestimate');
}
}
}
Now when I use:
var last_element = itemRate[itemRate.length - 1];
It gives me the number of digits/placeholders in each element of the array. So as per my example I know my array holds the values of .00 and 31.24 because I put them there for a test. So last_element will result in 3 and 5. How can I grab the value 31.24 or the last element period? I need the value not the number of digits.

var itemRate = new Array();// Not sure what you intend to do with this array
var histSearchResult = histSearch[h];
itemRate = histSearchResult.getValue('totalcostestimate'); // but note `itemRate` is no more an array here. Its a variable having the value of `totalcostestimate` in string format
Now coming to your use case
/* you're trying to get the length of the string value and subtracting -1 from it.
So its very obvious to get those number of digits */
var last_element = itemRate[itemRate.length - 1]; // returns you that index value of the string
If you want to get the last array value of your search i.e histSearch
You may want to do something like this
var last_element = histSearch[histSearch.length-1].getValue('totalcostestimate');
As a side note it is always recommended to validate the returning value from a saved search result. Because on a successful search it returns you an array object on the other hand if no result founds it'll return you null.
//likely to get an error saying can't find length from null
for (var h = 0; h <= histSearch.length; h++) {
}
You can use something like this
// Never enter into the loop if it is null
for (var h = 0; histSearch!=null && h <= histSearch.length; h++) {
}

Send emails from two distinct columns using data in google spreadsheets

Good morning.
Very new coder with little background. I need to merge data from a google spreadsheet into an email, without using an add-on. I borrowed this code from a site and I'm able to produce an email but it will only pull from the first email address column. I need to send an email to both the manager and director. Their email address will be stored in two separate columns with unique labels. I can't change the spreadsheet data as the spreadsheet is storing responses pulled from a survey form that is already in progress (example column layout below):
Name / Email Address / Director Name / Director Email Address / Response 1 / Response 2 / etc...
Everything I've researched will send an email from one column, but not two, or a "cc".
Below is the borrowed code. Would very much appreciate any help on how to modify the code to send the "response" data to both the Manager and Director in one email.
kind regards,
KA
function sendEmails() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var dataSheet = ss.getSheets()[0];
var dataRange = dataSheet.getRange(2, 1, dataSheet.getMaxRows() - 1, 15);

var emailTemplate = templateSheet.getRange("A1").getValue();
// Create one JavaScript object per row of data.
var objects = getRowsData(dataSheet, dataRange);
// For every row object, create a personalized email from a template and send
// it to the appropriate person.
for (var i = 0; i < objects.length; ++i) {
// Get a row object
var rowData = objects[i];
// Generate a personalized email.
// Given a template string, replace markers (for instance ${"First Name"}) with
// the corresponding value in a row object (for instance rowData.firstName).

// simply removed.
function fillInTemplateFromObject(template, data) {
var email = template;
// Search for all the variables to be replaced, for instance ${"Column name"}

// normalizeHeader ignores ${"} so we can call it directly here.
var variableData = data[normalizeHeader(templateVars[i])];
email = email.replace(templateVars[i], variableData || "");

According to the documentation : Mail App, the recipent represents the addresses of the recipients, separated by commas
So in order to send to several recipents, just make a string separated by comma:mike#example.com, mike2#example.com
You could pick the rows you want and do something like this:
MailApp.sendEmail(rowData[0].emailAddress + ',' + rowData[1].emailAdress, emailSubject, emailText);

Text Analysis webpage does not work

For a homework assignment, I have to make a web page that has a text area. The user inputs some text, hits the analyse button, and the output is supposed to be a list of the frequency of words of a given number of characters. For example, "one two three" would be two words of three characters and one word of five characters. The text area works fine, but I can"t seem to get the output to appear.
Here is the html:
<body>
<textarea id="text" rows="26" cols="80"></textarea>
<form>
<input type="button" id="analyse" value="Analyse Text">
</form>
<div id="output"></div>
</body>
The JavaScript file has 6 functions. The first function returns an array that stores the number of characters for each word in the input textarea:
function getWordInfo() {
var text = document.getElementById("text").value;
//the variable wordArray uses a regular expression to parse the input
var wordArray = text.split("/\w\w+/g");
var arrayLength = wordArray.length;
var charArray = [];
for (var i = 0; i < arrayLength; i++) {
var splitWord = wordArray[i].split("");
var wordLength = splitWord.length;
charArray.push(wordLength);
}
return charArray;
}
The second function is a simple object constructor that has a name property and a count property. The count property has a default value of 0.
function obCon(name,count) { //object constructor
this.name = name;
this.count = count;
count = typeof count !== "undefined" ? count : 0;
}
The third function returns an array that stores word objects. Each object has a name property and a count property. The name property is the number of characters in a word. The count property counts how many times an object with a given name property appears.
function arCon() { //array constructor
var charNum = getWordInfo();
var arrayLength = charNum.length;
var obArr = [];
for (var i = 0; i < arrayLength; i++) {
if (typeof obArr.indexOf( newOb.name === charNum[i] ) != "undefined" ) { // checks if the object needed exists
obArr.indexOf( newOb.name === charNum[i] ).count = obArr.indexOf( newOb.name === charNum[i] ).count + 1;
}else{
var newOb = new obCon(charNum[i]);
newOb.count = newOb.count + 1;
obArr.push(newOb);
}
}
return obArr;
}
The fourth function is a string formatter, meant format the objects from arCon into a single readable string, then store it in an array.
function formatter() {
var strAr = arCon();
var arrayLength = strAr.length;
var formatStr = [];
for (var i = 0; i < arrayLength; i++) {
var str = "Number of characters: " + strAr[i].name + ", Number of words with this length: " + strAr[i].count;
formatStr.push(str);
}
return formatStr;
}
The fifth function is called for an event handler, meant to handle the click of the analyse button. On click, it is meant to get the div tag, get the formatted array, then loop though each element in the array, where it creates a p element element, pulls the formatted string, sets the p element value to the formatted string, then appends the p element to the div tag.
function analyseButtonClick() {
var div = document.getElementById("output");
var str = formatter();
var arrayLength = str.length;
for (var i = 0; i < arrayLength; i++) {
var par = document.createElement("p");
var format = str[i];
par.value = format;
div.appendChild(par);
}
}
The sixth function is an init function that handles the button click.
function init() {
var button = document.getElementById("analyse");
button.onclick = analyseButtonClick;
}
window.onload = init;
I have run this though a validator, and it shows me that there are no syntax errors, so it must be a logic error. However, all the functions seem to do what they are supposed to do, so I am not sure where I went wrong.
edit1: ok, have replaced the third function with four new functions. a function that returns the highest number in the array returned by getWordInfo, a function that constructs objects with name properties from 2 up to that number, a function that update the count properties of the objects, and a function that removes unused objects. here they are:
function maxNum() {
var array = getWordInfo();
var num = Math.max.apply(Math, array);
return num;
}
function objArrCon() { //object array constructor
var num = maxNum();
var array1 = [];
for (var i = 2; i === num; i++) {
var myObj = new objCon(i,0);
array1.push(myObj);
}
return array1;
}
function objArrParse() { //updates the object with word info
var array1 = getWordInfo();
var array2 = objArrCon();
var loopLength1 = array1.length;
var loopLength2 = array2.length;
for (var i = 0; i < loopLength1; i++) {
for (var m = 0; m < loopLength2; m++) {
if (array2[m].name === array1[i]) {
array2[m].count++;
}
}
}
return array2;
}
function objArrTrun() { //removes unused objects
var array1 = objArrParse();
var loopLength = array1.length;
for (var i = 0;i < loopLength; i++) {
if (array1[i].count === 0) {
array.splice(i, array1);
}
}
return array1;
}
still does not work, but im getting there!

I have written this in jQuery because 1) it's not my homework assignment and 2) it would be good practice (for you) to translate it back into normal JavaScript. You'll need to rewrite the event handler, along with the two getters/setters ($("text area").val() and $("tbody").append()).
Your main problem is that you have made your solution too complicated! If all you want to do is display the number, Y, of words with length, X, then you should do the following:
Grab the value of the text area and store in text
Remove all non-alphanumeric characters.
Split the text string wherever one or more spaces is present and store it in text
Loop through the array and map each array element, based on its length, to wordMap
Loop through wordMap and append it to wherever in the DOM you want the results to be
fiddle
JavaScript
$("#analyze").click(function () {
var text = $("textarea").val().replace(/[^\d\w ]+/g," ").split(/[ ]+/);
// this grabs the value of the text area, replaces all non-numerical
// and non-alphabetical characters with "", and then splits it into an array
// wherever one or more spaces is present.
var wordMap = {};
// makes an object that will be used as an associative array
text.forEach(function (d) {
// loops through the array
// if there is no key called d.length in wordMap
if (!wordMap[d.length])
wordMap[d.length] = 1; // set its count to one
else
wordMap[d.length]++; //otherwise, increment it
})
// loop through all the properties of wordMap
for (var x in wordMap) {
$("tbody").append("<tr><td>" + x + "</td><td>"
+ wordMap[x] + "</td></tr");
}
console.log(wordMap);
})
HTML
<textarea placeholder="type something..."></textarea>
<button id="analyze">Click to analyze</button>
<div id="results">
<table>
<thead>
<th>Length of Word</th>
<th>Number of Occurrences</th>
</thead>
<tbody>

</table>
</div>

JavaScript - Pushing a value on an array after clearing it keeps the old values

I'm using JavaScript (prototype and ajax), PHP and MySQL to display some values from a database in textfields and a dropdown list, but I ran into a problem with JavaScript.
Every time a user clicks on an option in a list the values should update. These values are pushed in an array, but even after clearing it or setting its length to 0, the values get pushed to the end of how the array was before.
It all works fine the first time, but after that the array keeps on getting bigger and it adds more and more values to the dropdown list. Here's the code:
function artSelect(art){
//perform an Ajax request
var artRequest = new XMLHttpRequest();
//If the output is returned successfully, add it in the document
artRequest.onreadystatechange = function() {
if (artRequest.readyState==4) {
//Get the text
var text = artRequest.responseText;
//Create an array
var x = new Array();
//Create a variable for storing the position of the last semicolon (the values are seperated by semicolons)
var lastSemCol = 0;
//Split the text by scanning for semicolons and put them in an array
for (var i=0; i<text.length; i++) {
//If the current char is ";"
if (text[i] === ";") {
//Create a substring of the chars between the last ; and current ;
var value = text.substr(lastSemCol + 1, i-lastSemCol-1);
//Add the value to the array
Array.prototype.push(value);
lastSemCol = i;
}
}
//Set the values in the document
$("beschrijving").value = x[1];
$("kleur").value = x[2];
$("voorraad").value = x[3];
$("prijs").value = x[4];
$("srtc").value = x[5];
//Set the departments
for (var i=6; i < Array.prototype.size(x); i++) {
var option = document.createElement("option");
option.text = x[i];
$("afd").add(option);
}
//Clear the array (no effect)
x.clear();
x.length = 0;
x = new Array();
}
};
artRequest.open("GET", "server.php?mode=getArtikel&artikel=" + selected.value.substr(0,7), true);
artRequest.send(null);
}
