above is extract of my javascript code. What the code do is to create a table of inviting group from the xml file with accept and decline button. when user press accept, the table will disappear and the table below will move up. For now I am only testing my accept invitation button to see if it works.But
my onclick function in the accept button does not work for some reason I don't understand. the alert in acceptInvitation() is not read. Any help will be appreciated. Thanks
What about:
cellContent += "[...] onclick='acceptInvitation("+i+")'>"
This ensures that i is evaluated with the value of the variable instead of as a literal
Try to call it like this
onclick='acceptInvitation();'
Not like this
onclick='acceptInvitation(i)'
dont know if that's what's causing your problem but your outputting onclick='acceptInvitation(i)' Im guessing you want to output acceptInvitation(value-of-i), that is acceptInvitation(" + i + ")
while perhaps not addressing the central problem,
onclick='acceptInvitation(i)'
in this case i would be undefined.
onclick='acceptInvitation("+i+")'
would solve at least one problem. Also, you're using an unusual mixture of innerHTML and DOM methods. Why not stick to the DOM methods and use attachEvent/AddEventListener?
edit: A list apart has a good article on binding of variables at http://www.alistapart.com/articles/getoutbindingsituations/
The following is a somewhat specialized example. See the article for more generalized case (or use a library like Prototype)
var click_hdlr = function() {
return function() {
return acceptInvitation.apply(this,arguments);
}
}
var acc_btn = document.createElement("input");
acc_btn.setAttribute("type","button");
acc_btn.setAttribute("id","accept");
acc_btn.setAttribute("value","Accept");
acc_btn.addEventListener("click",click_hdlr(i),false);

I am new to the world of * AppScript * I am currently designing a ** WepApp ** which is made up of html lists that connect to Mysql, when I individually test my lists paint correctly and their icons modify and update the data, without However ** the problem is ** when I join all my lists and call them through their corresponding url only the last one paints me the others are blank. For example of 10 lists I call # 2 the log tells me to call 10; I call 5 the same thing happens and if I call 10 it paints the data and they are allowed to be modified.
Within what I have searched I find that my problem lies in the way I render my pages but I cannot find the right path, so I ask for your support.
function doGet(e) {
var template ;
var view = e.parameters.v;
if(view == null){
template = HtmlService.createTemplateFromFile("Index");
}if(view == "Index"){
template = HtmlService.createTemplateFromFile("Index");
}if(view != null && view != "Index"){
template = HtmlService.createTemplateFromFile(view);
}
return template.evaluate()
.setTitle('Documental')
.setSandboxMode(HtmlService.SandboxMode.IFRAME)
.setXFrameOptionsMode(HtmlService.XFrameOptionsMode.ALLOWALL);
}
function getTemplate(view){
return HtmlService.createTemplateFromFile(view);
}
and with this JavaScript method I connect my appscript code to pass it to my html
window.onload = function () {
google.script.run

.withFailureHandler(onFailure)
.readAreaPRE();

Thank you in advance, any correction to ask my question will be welcome.
I'm trying to send a telegram message to myself, every morning, with a different quote that I have listed in a Google Sheet. I wrote some code that adds messages to the list, but I can't seem to generate a random row from the list to send daily.
var token = "TOKEN";
var telegramAPI = "https://api.telegram.org/bot" + token;
var webAppAPI = "https://script.google.com/macros/s/GOOGLE_WEB_APP_ADDRESS";
var ssId = "SPREADSHEET_ID";
function getMe() {
var url = telegramAPI + "/getMe";
var response = UrlFetchApp.fetch(url);
Logger.log(response.getContentText());
}
function setWebhook() {
var url = telegramAPI + "/setWebhook?url=" + webAppAPI;
var response = UrlFetchApp.fetch(url);
Logger.log(response.getContentText());
}
function sendText(id,text) {
var url = telegramAPI + "/sendMessage?chat_id=" + id + "&text=" + text;
var response = UrlFetchApp.fetch(url);
Logger.log(response.getContentText());
}
function doGet(e) {
return HtmlService.createHtmlOutput("Test Data" + JSON.stringify(e,null,4));
}
function doPost(e) {
Logger.log(e);
var data = JSON.parse(e.postData.contents);
var text = data.message.text;
var what = data.message.text.split("-")[0]
var who = data.message.text.split("-")[1]
var id = data.message.chat.id;
var name = data.message.chat.first_name;
var response = "Hi " + name + ", this quote has been added to your database: " + text;
sendText(id,response);
SpreadsheetApp.openById(ssId).getSheets()[1].appendRow([new Date(),id,name,text,response,what,who]);
All of this works fine. I added a query that pulls them over to my Quote sheet from my Telegram Feed sheet, that I'll put here to help someone:
=IFERROR(QUERY('Telegram Feed'!$G$1:$G$98,"",-1),"Error")
Now that I'm pulling in quotes, I want to generate a random one from the list and schedule it to send to myself on a daily basis. I've included what I've tried below, but I can't seem to figure out what I'm doing wrong.
The randomizer is partially working, but seems to be grabbing all of the content, which I need to refactor to say something along the lines of:
message = f"{quote} + ' - ' + {author}"
Randomizer:
function randomizer() {
var ssa = SpreadsheetApp.openById(ssId);
var ss = ssa.getSheetByName('Quotes');
var range = ss.getRange(1,1,ss.getLastRow(), 2);
var data = range.getValues();
for(var i = 0; i < data.length; i++)
{
var j = Math.floor(Math.random()*(data[i].length));
var element = data[i][j];
ss.getRange(i+1, 6).setValue(element);
Logger.log(element);
}
}
Up until this point, it mostly works (even though I need to figure out how to fix the randomizer function as mentioned above. It's when I try to send a random message from the script to Telegram that I run into problems.
function sendQuote(what,who) {
var data = randomizer();
var dataJSON = JSON.parse(data.postData.contents);
var url = telegramAPI + "/sendMessage?chat_id=" + 'CHAT_ID_NUM' + "&text=" + what + " - " who;
}
I'm getting nothing back. Anyone know what I'm doing wrong?
EDIT:
I followed the suggestions from Дмитро-Булах & carlesgg97, and I refactored a bunch of my randomize code to give me a quote and author. For some reason, I'm now getting the error "TypeError: Cannot read property "postData" from undefined.: from the line that reads var dataJSON = JSON.parse(data.postData.contents);
Does anyone know why this is happening?
I'll close the issue within 24hrs regardless. Thanks for the help everybody!
function sendQuote(quote,author) {
var data = randomize();
var dataJSON = JSON.parse(data.postData.contents);
var encodedText = encodeURIComponent(quote + " - " + author);
var url = telegramAPI + "/sendMessage?chat_id=" + 'CHAT_ID' + "&text=" + encodedText;
UrlFetchApp.fetch(url);
}
function randomize() {
var sss = SpreadsheetApp.openById(ssId);
var ss = sss.getSheetByName('Quotes');
var length = ss.getLastRow();
var overshoot = 97 //monitor for changes as list size increases
var true_length = length-overshoot;
var line = (Math.random() * ((true_length - 2) + 1)) + 2;
var quote_cell = ss.getRange(line,2);
var quote = quote_cell.getValue();
var author_cell = ss.getRange(line,1);
var author = author_cell.getValue();
Logger.log(quote + " - " + author);
}
Seems like you may be having two different problems:
You are not encoding the text as URL-safe. To safely append data (in this case the text URL Query string parameter) to your URL, you should use encodeURIComponent().
You don't seem to actually be sending the request. Did you miss the UrlFetchApp.fetch() call?
See below an example that fixes both issues:
function sendQuote(what,who) {
var data = randomizer();
var dataJSON = JSON.parse(data.postData.contents);
var encodedText = encodeURIComponent(what + " - " + who);
var url = telegramAPI + "/sendMessage?chat_id=" + 'CHAT_ID_NUM' + "&text=" + encodedText;
UrlFetchApp.fetch(url);
}
I am creating a 'photos' page on a website. It uses PHP to retrieve the filenames in a directory, and then attempts to create divs (with images in them) programmatically with javascript. However, when I try to create 'w3-third' divs, edit the innerHTML so that it embeds an image, and (the problematic step) add them to the 'w3-row' div, it removes the existing children. Hence, there is only one image per row.
I have been looking for alternate code / solutions, but the element.appendChild() function seems to be the only method; I have tried element.children.push(), but element.children is an [HTMLCollection] which (I guess) is read-only.
$.getJSON("content/photospage/get_filenames.php", function(data){
var photoFileNames = data;
console.log(photoFileNames.length + " images to display.");
var photosDiv = document.getElementById("divPhotos");
for(var i = 0; i < photoFileNames.length; i += 3){
console.log("Loop! i=" + i);
var newRow = document.createElement("div");
newRow.classList.add("w3-row");
newRow.classList.add("w3-padding-8")
var newImg1 = newImg2 = newImg3 = document.createElement("div");
newImg1.classList.add("w3-third")
newImg2.classList.add("w3-third")
newImg3.classList.add("w3-third")
newImg1.innerHTML = "<img src='" + dir + photoFileNames[i] + "' class='w3-round w3-margin-bottom constrained'>";
newRow.appendChild(newImg1);
console.log("displayed img " + (i))
if(i+1 < photoFileNames.length){
newImg2.innerHTML = "<img src='" + dir + photoFileNames[i+1] + "' class='w3-round w3-margin-bottom constrained'>";
newRow.appendChild(newImg2);
console.log("displayed img " + (i+1))
}
if(i+2 < photoFileNames.length){
newImg3.innerHTML = "<img src='" + dir + photoFileNames[i+2] + "' class='w3-round w3-margin-bottom constrained'>";
newRow.appendChild(newImg3);
console.log("displayed img " + (i+2))
}
console.log(newRow.children);
photosDiv.appendChild(newRow);
}
The html element that exists by default:
<div class="w3-container w3-content w3-center w3-padding-32 " id="divPhotos">
</div>
Sorry for the large amount of code above. Thanks for any assistance, and I'm happy to clarify anything that I failed to mention. :)
Also, I am aware that the code is clunky and inefficient, so let me know if you pick up on anything I could do better. Thanks again! :)
With
var newImg1 = newImg2 = newImg3 = document.createElement("div");
you've created one object (an HTMLDivElement) in memory, which 3 variable names (newImg1, newImg2, newImg3) refer to. You do not have 3 separate elements. When you call appendChild with one of the elements, you remove it from wherever it previously existed in the DOM.
Since you want separate elements, you should do so explicitly:
var newImg1 = document.createElement("div");
var newImg2 = document.createElement("div");
var newImg3 = document.createElement("div");
You could make the code less repetitive by using another for loop instead of creating separate standalone elements:
for (let j = 0; j < 3; j++) {
const thisIndex = i + j;
if (thisIndex >= photoFileNames.length) {
break;
}
const img = document.createElement("div");
img.innerHTML = "<img src='" + dir + photoFileNames[thisIndex] + "' class='w3-round w3-margin-bottom constrained'>";
newRow.appendChild(img);
}
Premise:
I'm playing around with javascript and have been trying to display a populated JSON file with an array of people on the browser. I've managed to display it through ajax, but now I'm trying to perform the same task with jQuery.
Problem:
The problem is that it keeps saying customerdata[i] is undefined and can't seem to figure out why.
$(function() {
console.log('Ready');
let tbody = $("#customertable tbody");
var customerdata = [];
$.getJSON("MOCK_DATA.json", function(data) {
customerdata.push(data);
});
for (var i = 0; i < 200; i++) {
//Cell for name
let nameTD = $('<td>').text(customerdata[i].first_name + ", " + customerdata[i].last_name);
//Cell for birthdate
let mDate = moment(customerdata[i].birthdate);
let formattedmDate = mDate.format('YYYY-MM-DD');
let birthdateTD = $('<td>').text(formattedmDate);
//Cell for Address
let addressTD = $('<td>').html("City: " + customerdata[i].city + '<br>' + "Email: " + customerdata[i].email + '<br>' + '<a href=' + customerdata[i].website + '>Website</a>');
//Cell for Credits
let creditTD = $('<td>').text(customerdata[i].credits);
let row = $('<tr>').append(nameTD).append(birthdateTD).append(addressTD).append(creditTD);
tbody.append(row);
}
})
SAMPLE CONTENT OF MOCK_DATA.json
[
{"id":1,"first_name":"Tracey","last_name":"Jansson","email":"tjansson0#discuz.net","gender":"Female","ip_address":"167.88.183.95","birthdate":"1999-08-25T17:24:23Z","website":"http://hello.com","city":"Medellín","credits":7471},
{"id":2,"first_name":"Elsa","last_name":"Tubbs","email":"etubbs1#uol.com.br","gender":"Female","ip_address":"61.26.221.132","birthdate":"1999-06-28T17:22:47Z","website":"http://hi.com","city":"At Taḩālif","credits":6514}
]
Firstly, you're pushing an array into an array, meaning you're a level deeper than you want to be when iterating over the data.
Secondly, $.getJSON is an asynchronous task. It's not complete, meaning customerdata isn't populated by the time your jQuery is trying to append the data.
You should wait for getJSON to resolve before you append, by chaining a then to your AJAX call.
$.getJSON("MOCK_DATA.json")
.then(function(customerdata){
for(var i = 0; i < 200; i++){
//Cell for name
let nameTD = $('<td>').text(customerdata[i].first_name + ", " + customerdata[i].last_name);
//Cell for birthdate
let mDate = moment(customerdata[i].birthdate);
let formattedmDate = mDate.format('YYYY-MM-DD');
let birthdateTD = $('<td>').text(formattedmDate);
//Cell for Address
let addressTD = $('<td>').html("City: " +
customerdata[i].city + '<br>' + "Email: " +
customerdata[i].email + '<br>' + '<a
href='+customerdata[i].website+'>Website</a>');
//Cell for Credits
let creditTD = $('<td>').text(customerdata[i].credits);
let row = $('<tr>').append(nameTD).append(birthdateTD).append(addressTD).append(creditTD);
tbody.append(row);
}
})
You also won't need to define customerdata as an empty array at all with this approach.
The problem is that data is already an array.
so you should use:
customerdata = data;
otherwhise you are creating an array in the pos 0 with all the data
So I'm trying to insert one div into another both created with Javascript
I have the following code,
// Assign tool attributes to Javascript Variables
var tool_name = String(tool['tool_name']);
tool_name = tool_name.replace(/'/g, '');
var tool_inventory_number = String(tool['tool_inventory_number']);
tool_inventory_number = tool_inventory_number.replace(/'/g, '');
var tool_recnum = String(tool['tool_recnum']);
tool_recnum = tool_recnum.replace(/'/g, '');
// Create the divs for the search results
var toolDiv = document.createElement("div");
var toolDivPicture = document.createElement("div");
//todo: Insert picture into this toolDivPicture div
var toolDivDescription = document.createElement("div");
toolDivDescription = toolDivDescription.innerHTML + "<h2>" + tool_name + "</h3>" + " <br>" + "Inventory Number: " + tool_inventory_number;
// Assign class to search result toolDiv and add content to it.
toolDiv.className = "toolDiv";
toolDiv.appendChild(toolDivDescription);
I keep getting the following error,
Uncaught NotFoundError: Failed to execute 'appendChild' on 'Node': The new child element is null.
Could this be because I have to refrence the child div by id? I really just want to have javascript create a div that contains two other divs and then insert it into the page. Any help/suggestions are appreciated!
Since you marked the question with the jQuery tag, I assume that you have the jQuery library loaded:
// Create the divs for the search results
var toolDiv = $("<div/>");
var toolDivPicture = $("<div/>");
var toolDivDescription = $("<div/>");
toolDivDescription.html("<h2>" + tool_name + "</h3>" + " <br>" + "Inventory Number: " + tool_inventory_number);
// Assign class to search result toolDiv and add content to it.
toolDiv.addClass("toolDiv");
toolDiv.append(toolDivDescription);
Note that you start a h2 but end a h3.
jsFiddle
Try this:
Wrap up your JavaScript in an onload function. So first add:
<body onload="loadJS()">
Then put your javascript in the load function, so:
function loadJS() {
// Assign tool attributes to Javascript Variables
var tool_name = String(tool['tool_name']);
tool_name = tool_name.replace(/'/g, '');
var tool_inventory_number = String(tool['tool_inventory_number']);
tool_inventory_number = tool_inventory_number.replace(/'/g, '');
var tool_recnum = String(tool['tool_recnum']);
tool_recnum = tool_recnum.replace(/'/g, '');
// Create the divs for the search results
var toolDiv = document.createElement("div");
var toolDivPicture = document.createElement("div");
//todo: Insert picture into this toolDivPicture div
var toolDivDescription = document.createElement("div");
toolDivDescription = toolDivDescription.innerHTML + "<h2>" + tool_name + "</h3>" + " <br>" + "Inventory Number: " + tool_inventory_number;
// Assign class to search result toolDiv and add content to it.
toolDiv.className = "toolDiv";
toolDiv.appendChild(toolDivDescription);
}
