I'm trying to filter in an array by data in another array using concat in a for loop. The elements of the following code are logging correctly, but the final array is logging an empty array.
function Shipments (){
var app = SpreadsheetApp;
var movementSS = app.getActiveSpreadsheet();
var infoSheet = movementSS.getSheetByName("Update Info");
var orderInfoSheet = movementSS.getSheetByName("Order Info");
var targetSheet = movementSS.getSheetByName("Shipments");
var ShipLogSS = app.openByUrl(URL).getSheetByName("Shipping Details");
var ShipArr = ShipLogSS.getRange(3,1,ShipLogSS.getLastRow(),ShipLogSS.getLastColumn()).getValues().
filter(function(item){if(item[1]!=""){return true}}).
map(function(r){return [r[0],r[1],r[2],r[4],r[10],r[11],r[16],r[18],r[23]]});
var supplierData = orderInfoSheet.getRange(3,6,orderInfoSheet.getLastRow(),1).getValues().
filter(function(item){if(item[0]!=""){return true}});
var supplierList = [];
for (var i in supplierData) {
var row = supplierData[i];
var duplicate = false;
for (var j in supplierList) {
if (row.join() == supplierList[j].join()) {
duplicate = true;
}
}
if (!duplicate) {
supplierList.push(row);
}
}
var supplierFilter = [];
for(var i = 0; i < supplierList.length; i++){
var shipments = ShipArr.filter(function(item){if(item[4]===supplierList[i][0]){return true}});
supplierFilter.concat(shipments);
}
Logger.log(supplierFilter);
}
Any help would be greatly appreciated!
You need to assign the result of concat onto the supplierFilter in order to see the changes in later iterations and in the outer scope.
You can also return the comparison done inside the .filter callback immediately, instead of an if statement - it looks a bit cleaner.
var supplierFilter = [];
for (var i = 0; i < supplierList.length; i++) {
var shipments = ShipArr.filter(function (item) { return item[4] === supplierList[i][0]; });
supplierFilter = supplierFilter.concat(shipments);
}
Logger.log(supplierFilter);
I wanted to practice my vanilla javascript skills since I've been so library-heavy lately. My goal was to filter an array of JSON data (by events after 10/01/2015), and then append them as list items to the DOM, with the class being "events", and give the ability to delete events. Why isn't this working?
https://jsfiddle.net/youngfreezy/7jLswj9b/
function convertToJSData(arr) {
for (var i = 0; i < arr.length; i++) {
// var from = "10-11-2011";
var from = arr[i].date;
var numbers = from.match(/\d+/g);
var date = new Date(numbers[2], numbers[0] - 1, numbers[1]);
arr[i].date = date;
}
console.log(arr[0].date);
return arr;
}
function getByDate(data) {
convertToJSData(data);
var filterDate = new Date(2015, 09, 01);
return data.filter(function (el) {
return el.date >= filterDate;
});
}
var filteredDates = getByDate(events);
filteredDates.sort(function (a, b) {
return a.date - b.date;
});
console.log(filteredDates.length); //returns 6
var appendHTML = function (el) {
var list = document.getElementById("events");
for (var i = 0; i < filteredDates.length; i++) {
var listItem = filteredDates[i].name;
listItem.className = "event-list";
list.appendChild(listItem);
}
};
appendHTML(document.body);
var deleteEvent = function () {
var listItem = this.parentNode;
var ul = listItem.parentNode;
//Remove the parent list item from the ul
ul.removeChild(listItem);
}
when you do:
var listItem = filteredDates[i].name;
listItem.className = "event-list";
list.appendChild(listItem);
listItem is a string. You cannot append it as a child, you need to create a DOM element and append that:
var newEl = document.createElement('div');
newEl.className = "event-list";
newEl.innerHTML = filteredDates[i].name;
list.appendChild(newEl);
On a separate note, to just focus on the vanilla JS part of the question, maybe something like the following should illustrate the idea more generally:
let newElement = document.createElement("div");
newElement.innerHTML += `<ul><li>Item 1</li><li>Item 2</li></ul>`;
newElement.className = "item-list";
document.getElementById("root").append(newElement);
I have a javascript object as below
var mydata=[
{"Club":"Blackburn","EventNo":1,"Pnts":3,"CumPnts":0},
{"Club":"Blackburn","EventNo":2,"Pnts":1,"CumPnts":0},
{"Club":"Blackburn","EventNo":3,"Pnts":4,"CumPnts":0},
{"Club":"Preston","EventNo":1,"Pnts":2,"CumPnts":0},
{"Club":"Preston","EventNo":2,"Pnts":4,"CumPnts":0},
{"Club":"Preston","EventNo":3,"Pnts":2,"CumPnts":0},]
I want to update the object so that CumPnts contains a running points total for each Club as below
{"Club":"Blackburn","EventNo":1,"Pnts":3,"CumPnts":3},
{"Club":"Blackburn","EventNo":2,"Pnts":1,"CumPnts":4},
{"Club":"Blackburn","EventNo":3,"Pnts":4,"CumPnts":8},
{"Club":"Preston","EventNo":1,"Pnts":2,"CumPnts":2},
{"Club":"Preston","EventNo":2,"Pnts":4,"CumPnts":6},
{"Club":"Preston","EventNo":3,"Pnts":1,"CumPnts":7},]
Any help would be much appreciated
Here is a function that loops through the list and updates it after it's been added. But I suspect that the events come in one at a time so there could be another function that can look the cumPtns obj and take from that. Here is for the current list.
var cumData = {};
var mydata=[
{"Club":"Blackburn","EventNo":1,"Pnts":3,"CumPnts":0},
{"Club":"Blackburn","EventNo":2,"Pnts":1,"CumPnts":0},
{"Club":"Blackburn","EventNo":3,"Pnts":4,"CumPnts":0},
{"Club":"Preston","EventNo":1,"Pnts":2,"CumPnts":0},
{"Club":"Preston","EventNo":2,"Pnts":4,"CumPnts":0},
{"Club":"Preston","EventNo":3,"Pnts":2,"CumPnts":0}];
function updateMyData() {
for (var i = 0; i < mydata.length; i++) {
var item = mydata[i];
if(cumData[item.Club] == undefined) {
cumData[item.Club] = {};
cumData[item.Club] = item.Pnts;
} else {
cumData[item.Club] = cumData[item.Club] + item.Pnts;
}
mydata[i].CumPnts = cumData[item.Club];
};
console.log(mydata);
//if you want to return it you can have this line below. Otherwise the object is updated so you'll probably want to do something with it once it's updated. Call back maybe?
return mydata;
}
updateMyData();
The first time it encounters a team it adds it to an array and so does with the corresponding cumPnts, so we can keep track of whether we checked a team earlier or not.
var tmArr = [];
var cumArr = [];
for(var i = 0; i < mydata.length; i++) {
var elm = mydata[i];
var club = elm.Club;
var points = elm.Pnts;
var idx = tmArr.indexOf(club);
if(idx > -1) {
cumArr[idx] += points;
elm.CumPnts = cumArr[idx];
}
else {
elm.CumPnts = points;
tmArr[tmArr.length] = club;
cumArr[cumArr.length] = points;
}
}

I have to fetch data from the PHP web service in an array and then display it on HTML page using JavaScript. I have used a for loop to do so. But it doesn’t render proper output. Due to innerHTML the output gets replaced. Please help with your suggestions. Here is my code:
function jsondata(data){
alert("JSONdata");
var parsedata = JSON.parse(JSON.stringify(data));
var main_category = parsedata["main Category"];
for (var i = 0; i <= main_category.length; i++) {
menu = JSON.parse(JSON.stringify(main_category[i]));
menu_id[i] = menu['mcatid'];
menu_title[i] = menu['mcattitle'];
menu_img[i] = menu['mcatimage'];
pop_array.push(menu_id[i], menu_title[i], menu_img[i]);
//alert(pop_array);
for (var i = 0; i < main_category.length; i++) {
alert("for start");
var category = document.createElement("li");
document.getElementById("mylist").appendChild(category);
//document.getElementById("mylist").innerHTML='<table><tr><td>'+pop_array[i]+'</td></tr></table>';
document.write(pop_array.join("<br></br>"));
alert("for end");
}
}
}
Although I don't get why pop_array was used here but I assume that you are trying to display the category info as a li tag.
You should set category.innerHTML instead of document.getElementById("mylist").innerHTML.
function jsondata(data){
var parsedata = JSON.parse(JSON.stringify(data));
var main_category = parsedata["main Category"];
for (var i = 0; i < main_category.length; i++) {
var menu = main_category[i];
var category = document.createElement("li");
category.innerHTML = menu['mcattitle']; // construct your own html here
document.getElementById("mylist").appendChild(category);
}
}
When I try var a = ar_url2.concat(ar_desc2); to join my arrays into one it returns null. I'm sure it's trivial but I spent a few hours stuck on this now and an explanation as why this is happening would be great. In my code bellow I tried while(ar_url2.length)a.push(ar_url2.shift()); and it returns same null...
function agregar() {
var i = 0,
textarea;
var ar_desc = [];
while (textarea = document.getElementsByTagName('textarea')[i++]) {
if (textarea.id.match(/^desc_([0-9]+)$/)) {
ar_desc.push(textarea.id);
}
}
var desc_count_demo = document.getElementById('desc_count').value;
var desc_count = desc_count_demo - 1;
i = 0;
var ar_desc2 = [];
var campo = null;
while (i <= desc_count) {
campo = document.getElementById(ar_desc[i]).value;
ar_desc2[ar_desc[i]] = campo;
i++;
}
i = 0;
var input;
var ar_url = [];
while (input = document.getElementsByTagName('input')[i++]) {
if (input.id.match(/^url_([0-9]+)$/)) {
ar_url.push(input.id);
}
}
var url_count_demo2 = document.getElementById('url_count').value;
var url_count2 = url_count_demo2 - 1;
i = 0;
var ar_url2 = [];
while (i <= url_count2) {
campo = document.getElementById(ar_url[i]).value;
ar_url2[ar_url[i]] = campo;
i++;
}
// var a = Array.prototype.concat.call(ar_url2, ar_desc2);
while (ar_url2.length) a.push(ar_url2.shift());
function url(data) {
var ret = [];
for (var d in data)
ret.push(encodeURIComponent(d) + "=" + encodeURIComponent(data[d]));
return ret.join("&");
}
window.open('alta1.php?'+url(a));
}
EDIT: If I pass to function url(ar_url2) or url(ar_desc2) the returned values in the URL are
http://localhost/proj1/alta1.php?url_0=inpit&url_1=input
and
http://localhost/proj1/alta1.php?desc_0=input&desc_1=input
But still cannot merge both into one...
One thing I see is your ar_url Array is filled by:
while(input=document.getElementsByTagName('input')[i++]){
if(input.id.match(/^url_([0-9]+)$/)){
ar_url.push(input.id);
}
}
Since you the putting the whole id in the array, it will be filled with things like: 'url_0', 'url_1', 'url_2', etc...
Later you do:
ar_url2[ar_url[i]] = campo;
When you index into ar_url, you get out the 'url_XXX' strings. That means you are setting the 'url_XXX' properties on ar_url2 instead of filling in the elements of the array.
Try changing your second loop to:
while(input=document.getElementsByTagName('input')[i++]){
var result;
if(result = input.id.match(/^url_([0-9]+)$/)){
ar_url.push(+result[1]);
}
}
To use the value captured in the ([0-9]+) portion of the RegExp instead of the entire 'url_XXX' string.
