how can i alternate row class after api data

I have tried everything i know and can't get an alterate tablerow class to work , without having all the rows duplicated or having a bunch of dummy rows inserted
Here is what i have
<script>
fetch("https://www63.myfantasyleague.com/2021/export?TYPE=league&L=43570&JSON=1").then(
res => {
res.json().then(
data => {
console.log(data.league.franchises.franchise);
if (data.league.franchises.franchise.length > 0) {
var temp = "";
temp += "<table id='league_emails'>";
temp += "<tbody>";
temp += "<tr><th>Franchise</th><th>Owner Name</th><th>Email</th></tr>";
data.league.franchises.franchise.forEach((itemData) => {
for (var i = 0; i < data.league.franchises.franchise.length; i++) {
if (i % 2)
temp += '<tr class="eventablerow">';
else
temp += '<tr class="oddtablerow">';
}
temp += "<td>" + itemData.name + "</td>";
temp += "<td>" + itemData.owner_name + "</td>";
temp += "<td>" + itemData.email + "</td>";
});
temp += "</tbody>";
temp += "</table>";
document.getElementsByClassName('commish_league_safe')[0].innerHTML = temp;
}
}
)
}
)
</script>
<div class="commish_league_safe"></div>
The issue lays here and i have tried a dozen things and wrapped it different ways
for (var i = 0; i < data.league.franchises.franchise.length; i++) {
if (i % 2)
temp += '<tr class="eventablerow">';
else
temp += '<tr class="oddtablerow">';
}

<script>
fetch(https://www63.myfantasyleague.com/2021/export?TYPE=league&L=43570&JSON=1).then(
res => {
res.json().then(
data => {
console.log(data.league.franchises.franchise);
if (data.league.franchises.franchise.length > 0) {
var temp = "";
temp += "<table id='league_emails'>";
temp += "<tbody>";
temp += "<tr><th>Franchise</th><th>Owner Name</th><th>Email</th></tr>";
data.league.franchises.franchise.forEach((itemData,i) => {
/* for (var i = 0; i < data.league.franchises.franchise.length; i++) { */
if (i % 2)
temp += '<tr class="eventablerow">';
else
temp += '<tr class="oddtablerow">';
/* } */
temp += "<td>" + itemData.name + "</td>";
temp += "<td>" + itemData.owner_name + "</td>";
temp += "<td>" + itemData.email + "</td>";
temp += "</tr>";
});
temp += "</tbody>";
temp += "</table>";
document.getElementsByClassName('commish_league_safe')[0].innerHTML = temp;
}
}
)
}
)
</script>
<div class="commish_league_safe"></div>
Just before ending the loop close the tr tag.
temp += "" + itemData.email + ""; after this line just add closing tag to append that to temp variable.

Pulling data from SQLite, but data is undefined

I have a class project where I need to pull data from my SQLite DB and place it into <table>.
But every time I reload the page I get this Table image and I was hoping for some help. I'm new to JavaScript and I need to finish this task in a few hours, I've tried to pull the data into an object and from the object into this line str += "<td>" + results.rows.item(i).Firstname + "</td>" and still it didn't work.
db.transaction(function (tx) {
tx.executeSql('SELECT * FROM Customers_Table ', [], function (tx, results) {
var len = results.rows.length, i;
document.getElementById("tablea").innerHTML = '';
var str = '';
str += "<th>FirstName</th>";
str += "<th>LastName</th>";
str += "<th>Address</th>";
str += "<th>City</th>";
str += "<th>Email</th>";
for (i = 0; i < len; i++) {
str += "<tr>";
str += "<td>" + results.rows.item(i).Firstname + "</td>";
str += "<td>" + results.rows.item(i).Lastname + "</td>";
str += "<td>" + results.rows.item(i).Address + "</td>";
str += "<td>" + results.rows.item(i).City + "</td>";
str += "<td>" + results.rows.item(i).Email + "</td>";
str += "</tr>";
document.getElementById("tablea").innerHTML += str;
str = '';
}
});
});

Well, considering that you have data in results. It should be used as:
results.rows.item[i].Firstname
NOT
results.rows.item(i).Firstname

Finally figured out the problem, the .Firstname and the rest didn't match the column names from the Db table, it was lowercase,look carefully at your code guys!!

How to get the specific item from array on click in javascript table created using javascript

My code is this
var html = "<table>";
for (var i = 0; i < data.length; i++) {
html += "<tr>";
html += "<td>" + data[i].personName + "</td>";
html += "<td>" + data[i].fatherName + "</td>";
html += "<td>" + data[i].personPhone + "</td>";
html += "<td>" + data[i].personCnic + "</td>";
html += "<td>" + data[i].deliveryDate + "</td>";
html += "<td>" + data[i].submissionDate + "</td>";
html += "<td>" + data[i].year + "</td>";
html += "<td>" + data[i].session + "</td>";
html += "<td>" + data[i].board + "</td>";
html += "<td>" + data[i].amount + "</td>";
html += "</tr>";
}
html += "</table>";
document.getElementById("box").innerHTML = html;
How can I use an event listeners using this approach?
I have seen many methods but none of that match my scenario.

You need to add an onClick which is different for every row, in there you pass as parameter the row index :) than you can handle it on the function.
var html = "<table>";
for (var i = 0; i < data.length; i++) {
html+="<tr onclick='myFunction("+i+")'>";
html+="<td>"+data[i].personName+"</td>";
html+="<td>"+data[i].fatherName+"</td>";
html+="<td>"+data[i].personPhone+"</td>";
html+="<td>"+data[i].personCnic+"</td>";
html+="<td>"+data[i].deliveryDate+"</td>";
html+="<td>"+data[i].submissionDate+"</td>";
html+="<td>"+data[i].year+"</td>";
html+="<td>"+data[i].session+"</td>";
html+="<td>"+data[i].board+"</td>";
html+="<td>"+data[i].amount+"</td>";
html+="</tr>";
}
html+="</table>";
function myFunction(x) {
console.log('index' + x + 'was clicked')
// do the handling here
}
HERE YOU HAVE YOUR DEMO
let data = [{ personName: "test1"}, {personName: "test2"}]
var html = "<table>";
for (var i = 0; i < data.length; i++) {
html+="<tr onclick='myFunction("+i+")'>";
html+="<td>"+data[i].personName+"</td>";
html+="</tr>";
}
html+="</table>";
document.getElementById("demo").innerHTML = html;
function myFunction(i) {
console.log('index ' + i + ' was clicked')
// do the handling here
console.log(data[i])
}
<p id="demo"></p>

You can add the event listeners after you adding their html into the DOM.
Like this:
document.getElementById("box").querySelectorAll('tr').forEach(tr => {
tr.addEventListener('click', function() {
console.log(tr.textContent);
});
});
And working demo: (I added some dumb data so the demo will work)
const data = new Array(5).fill(0).map((_, idx) => ({
personName: `personName-${idx}`,
fatherName: `fatherName-${idx}`,
personPhone: `personPhone-${idx}`,
personCnic: `personCnic-${idx}`,
deliveryDate: `deliveryDate-${idx}`,
submissionDate: `submissionDate-${idx}`,
year: `year-${idx}`,
session: `session-${idx}`,
board: `board-${idx}`,
amount: `amount-${idx}`
}));
var html = "<table>";
for (var i = 0; i < data.length; i++) {
html += "<tr>";
html += "<td>" + data[i].personName + "</td>";
html += "<td>" + data[i].fatherName + "</td>";
html += "<td>" + data[i].personPhone + "</td>";
html += "<td>" + data[i].personCnic + "</td>";
html += "<td>" + data[i].deliveryDate + "</td>";
html += "<td>" + data[i].submissionDate + "</td>";
html += "<td>" + data[i].year + "</td>";
html += "<td>" + data[i].session + "</td>";
html += "<td>" + data[i].board + "</td>";
html += "<td>" + data[i].amount + "</td>";
html += "</tr>";
}
html += "</table>";
const box = document.getElementById("box");
box.innerHTML = html;
box.querySelectorAll('tr').forEach(tr => {
const _tr = tr;
tr.addEventListener('click', () => {
console.log(_tr.textContent);
});
});
<div id="box"></div>

display multiple image into HTML table using jquery [duplicate]

This question already has answers here:
How to return an image from http source in Javascript
(5 answers)
Closed 3 years ago.
Hi I want to display multiple image into html table using jquery check my code for more clearification.
In Console i get only image source as
<img src="uploads/">
$.ajax({
url : 'check.php',
success: function (data) {
data = $.parseJSON(data);
var html = "";
for(var a = 0; a < data.length; a++) {
var firstName = data[a].first_name;
var email = data[a].email;
var dob = data[a].dob;
var country = data[a].country;
var gender = data[a].gender;
var meal= data[a].meal;
var img = data[a].profile_pic;
var array = img.split(',');
for (var i = 0; i < array.length; i++) {
var src = "uploads/"+ array[i];
var img1 = '<img src='+ src +'>';
}
html += "<tr>";
html += "<td>" + firstName + "</td>";
html += "<td>" + email + "</td>";
html += "<td>" + dob + "</td>";
html += "<td>" + country + "</td>";
html += "<td>" + gender + "</td>";
html += "<td>" + meal + "</td>";
html += "<td>" + img1 + "</td>";
html += "</tr>";
document.getElementById("data").innerHTML += html;
}
},

Just move your img content inside for loop.
$.ajax({
url : 'check.php',
success: function (data) {
data = $.parseJSON(data);
var html = "";
for(var a = 0; a < data.length; a++) {
var firstName = data[a].first_name;
var email = data[a].email;
var dob = data[a].dob;
var country = data[a].country;
var gender = data[a].gender;
var meal= data[a].meal;
var img = data[a].profile_pic;
var array = img.split(',');
html += "<tr>";
html += "<td>" + firstName + "</td>";
html += "<td>" + email + "</td>";
html += "<td>" + dob + "</td>";
html += "<td>" + country + "</td>";
html += "<td>" + gender + "</td>";
html += "<td>" + meal + "</td>";
html += "<td>";
for (var i = 0; i < array.length; i++) {
var src = "uploads/"+ array[i];
var img1 = '<img src='+ src +'>';
html += img1
}
html += "</td>";
html += "</tr>";
document.getElementById("data").innerHTML += html;
}
},

Create a table in javascript from returned JSON object by http get

This is the function in my javascript. Triggered by an onclick function by an another function.
function getValueUsingParentTag(){
var tv_type = [];
var screen_size = [];
var connectivity = [];
var features = [];
var chkArray = [tv_type,screen_size,connectivity,features];
$("#tvtype input:checked").each(function() {
tv_type.push($(this).val());
});
$("#screensize input:checked").each(function() {
screen_size.push($(this).val());
});
$("#connection input:checked").each(function() {
connectivity.push($(this).val());
});
$("#feature input:checked").each(function() {
features.push($(this).val());
});
console.log(chkArray);
//alert(JSON.stringify(chkArray));
alert('hello');
$.get("output-tv.php",{tv_type:tv_type,screen_size:screen_size,connectivity:connectivity,features:features},function(chkArray){
});
}
This is the sample json object returned
{"result":[
{"product_code":"B2810","tv_name":"32B2810","size":"32","tv_type":"INTERNET TV"},
{"product_code":"B2610","tv_name":"48B2610","size":"48","tv_type":"INTERNET TV"}
]}
I need to create a table in javascript based on the json object returned. I dont know how. Please Help.

following function builds the table in a string.
function getTable(data) {
var html = "";
html += "<table><tr><td>product_code</td><td>tv_name</td><td>size</td><td>tv_type</td></tr>";
html += "<tr>";
for(var i = 0, ceiling = data.result.length; i < ceiling; i++) {
var row = data.result[i];
html += "<td>" + row.product_code + "</td>";
html += "<td>" + row.tv_name + "</td>";
html += "<td>" + row.size + "</td>";
html += "<td>" + row.tv_type + "</td>";
}
html += "</tr>";
html += "</table>";
return html;
}
suppose you have a div with id mydiv, you can add the table to this div with following code:
document.getElementById("mydiv").innerHTML = getTable(data);

Here's a simple Javascript only loop example:
http://jsfiddle.net/mCLVL/
var tableData = {"result":[
{"product_code":"B2810","tv_name":"32B2810","size":"32","tv_type":"INTERNET TV"},
{"product_code":"B2610","tv_name":"48B2610","size":"48","tv_type":"INTERNET TV"}
]};
var tableHTML = "<table>";
for (var i = 0; i < tableData["result"].length; i++) {
tableHTML += "<tr>";
tableHTML += "<td>" + tableData["result"][i]["product_code"] + "</td>";
tableHTML += "<td>" + tableData["result"][i]["tv_name"] + "</td>";
tableHTML += "<td>" + tableData["result"][i]["size"] + "</td>";
tableHTML += "<td>" + tableData["result"][i]["tv_type"] + "</td>";
tableHTML += "</tr>";
}
tableHTML += "</table>";
console.log(tableHTML);

It will be so simple by using JSRender. I made a fiddle using jsrender template check it.
