Tds automation in Javascript - javascript

const q3Msg = document.getElementById('tableq3');
var value = [{
id: 1,
result: 65,
situation: 'YES'
}, {
id: 2,
result: 22,
situation: 'NO'
}];
function q3Calc() {
q3Msg.classList.remove('hidden');
var table = document.createElement('tbody'), tr, td, row, cell;
for (row = 0; row < value.length; row++) {
console.log(value);
tr = document.createElement('tr');
for (cell = 0; cell < 3; cell++) {
td = document.createElement('td');
tr.appendChild(td);
td.innerHTML = value;
}
table.appendChild(tr);
}
document.getElementById('tableq3').appendChild(table);
}
I have the above code for automate tds in html. But I have the below image as a result.
How can I show each array index in a separate td?
For example, in the first row, I would like show 1 65 YES, and next row 2 22 NO

Your porblem is in td.innerHTML = value;. Replace it with td.innerHTML = value[row][Object.keys(value[row])[cell]]; to get expected value.
const q3Msg = document.getElementById('tableq3');
var value = [{
id: 1,
result: 65,
situation: 'YES'
}, {
id: 2,
result: 22,
situation: 'NO'
}];
function q3Calc() {
q3Msg.classList.remove('hidden');
var table = document.createElement('tbody'),
tr, td, row, cell;
for (row = 0; row < value.length; row++) {
console.log(value);
tr = document.createElement('tr');
for (cell = 0; cell < 3; cell++) {
td = document.createElement('td');
tr.appendChild(td);
td.innerHTML = value[row][Object.keys(value[row])[cell]];
}
table.appendChild(tr);
}
document.getElementById('tableq3').appendChild(table);
}
q3Calc();
td {
padding: 10px;
border: solid 1px #ddd;
}
<div id="tableq3"></div>

The main problems were that you weren't accessing each element (object in this case) in the array (you never used row after assigning it).
Then you never used the keys within each object (you were just calling value which means each time you were basically grabbing the entire array each time).
const q3Msg = document.getElementById('tableq3');
var value = [{
id: 1,
result: 65,
situation: 'YES'
}, {
id: 2,
result: 22,
situation: 'NO'
}];
function q3Calc() {
q3Msg.classList.remove('hidden');
var table = document.createElement('tbody'), tr, td, row, cell;
for (row = 0; row < value.length; row++) {
console.log(value[row]);
tr = document.createElement('tr');
for (let key in value[row]) {
td = document.createElement('td');
td.innerHTML = value[row][key];
tr.appendChild(td);
}
table.appendChild(tr);
}
document.getElementById('tableq3').appendChild(table);
}
q3Calc();
td {
padding: 5px;
}
<div id='tableq3'>
</div>

Do you want that?
const q3Msg = document.getElementById('tableq3');
var value = [{
id: 1,
result: 65,
situation: 'YES'
}, {
id: 2,
result: 22,
situation: 'NO'
}];
function q3Calc() {
// q3Msg.classList.remove('hidden');
var table = document.createElement('tbody'), tr, td, row, cell;
for (row = 0; row < value.length; row++) {
console.log(value);
tr = document.createElement('tr');
for (cell = 0; cell < 3; cell++) {
td = document.createElement('td');
tr.appendChild(td);
td.innerHTML = '['+value[row].id+','+value[row].result+','+value[row].situation+']';
}
table.appendChild(tr);
}
document.getElementById('tableq3').appendChild(table);
}
q3Calc();
<div id="tableq3"></div>

Trying to find a way to make new columns with JS

I am building a table with JavaScript. If you check the link you can see it is all in one column, but I need the name. prices, and images in separate columns. I am honestly not sure where to start to do this, so I'm looking for some help.
https://jsfiddle.net/wL28gd10/
JS
window.addEventListener("load", function(){
// ARRAYs
var itemName = ["BLT", "PBJ", "TC", "HC", "GC"];
var itemPrice = ["$1", "$2", "$3", "$4", "$5"];
var itemPhoto =
["images/blt.jpg","images/pbj.jpg","images/tc.jpg","images/hc.jpg","images/gc.jpg"];
//Create HTML Table
var perrow = 1,
table = document.createElement("table"),
row = table.insertRow();
// Loop through itemName array
for (var i = 0; i < itemName.length; i++) {
// Add cell
var cell = row.insertCell();
cell.innerHTML = itemName[i];
// Brreak into next row
var next = i + 1;
if (next%perrow==0 && next!=itemName.length) {
row = table.insertRow();
}
}
// Loop through itemPrice array
for (var i = 0; i < itemPrice.length; i++) {
// Add cell
var cell = row.insertCell();
cell.innerHTML = itemPrice[i];
// Break into next row
var next = i + 1;
if (next%perrow==0 && next!=itemPrice.length) {
row = table.insertRow();
}
}
// Loop through itemPhoto array
for (var i = 0; i < itemPhoto.length; i++) {
// Add cell
var cell = row.insertCell();
cell.innerHTML = itemPhoto[i];
// Break into next row
var next = i + 1;
if (next%perrow==0 && next!=itemPhoto.length) {
row = table.insertRow();
}
}
// Attach table to HTML id "menu-table"
document.getElementById("menu-table").appendChild(table);
});
Just create all of your columns in one loop, like:
for (var i = 0; i < itemName.length; i++) {
var row = table.insertRow();
// Add cell
var cell = row.insertCell();
cell.innerHTML = itemName[i];
cell = row.insertCell();
cell.innerHTML = itemPrice[i];
// Add cell
cell = row.insertCell();
cell.innerHTML = itemPhoto[i];
}
You only really need one loop.
window.addEventListener("load", function(){
// ARRAYs
var itemName = ["BLT", "PBJ", "TC", "HC", "GC"];
var itemPrice = ["$1", "$2", "$3", "$4", "$5"];
var itemPhoto = ["images/blt.jpg","images/pbj.jpg","images/tc.jpg","images/hc.jpg","images/gc.jpg"];
//Create HTML Table
var perrow = 1,
table = document.createElement("table");
// Loop through itemName array
for (var i = 0; i < itemName.length; i++) {
let row = table.insertRow();
// Add cell
var cell = row.insertCell();
cell.innerHTML = itemName[i];
var cell = row.insertCell();
cell.innerHTML = itemPrice[i];
var cell = row.insertCell();
cell.innerHTML = itemPhoto[i];
}
// Attach table to HTML id "menu-table"
document.getElementById("menu-table").appendChild(table);
});
table { border-collapse: collapse; }
table tr td {
border: 1px solid black;
padding: 10px;
background-color: white;
}
<div id="menu-table"></div>

Search Function to table

I have used the following code that takes my array and converts it to a HTML table.
const MOUNTAINS = [
{name: "Kilimanjaro", height: 5895, place: "Tanzania"},
{name: "Everest", height: 8848, place: "Nepal"},
{name: "Mount Fuji", height: 3776, place: "Japan"},
{name: "Vaalserberg", height: 323, place: "Netherlands"},
{name: "Denali", height: 6168, place: "United States"},
{name: "Popocatepetl", height: 5465, place: "Mexico"},
{name: "Mont Blanc", height: 4808, place: "Italy/France"}
];
function buildTable(data) {
let table = document.createElement("table");
let fields = Object.keys(data[0]);
let headRow = document.createElement("tr");
fields.forEach(function(field) {
let headCell = document.createElement("th");
headCell.appendChild(document.createTextNode(field));
headRow.appendChild(headCell);
});
table.appendChild(headRow);
data.forEach(function(object) {
let row = document.createElement("tr");
fields.forEach(function(field) {
let cell = document.createElement("td");
cell.appendChild(document.createTextNode(object[field]));
if (typeof object[field] == "number") {
cell.style.textAlign = "right";
}
row.appendChild(cell);
});
table.appendChild(row);
});
return table;
}
document.querySelector("#mountains").appendChild(buildTable(MOUNTAINS));
I am now trying to make a filter/search function to this table. When a user types in "K", only mountains starting with the letter K should be displayed. I have tried the following:
function searchTable() {
var input, filter, table, tr, td, i;
input = document.getElementById(myInput);
filter = input.value.toUpperCase();
table = document.getElementsByTagName("table");
tr = tr.getElementsByTagName("tr");
for(i = 0; < tr.length; i++;){
td = tr[i].getElementsByTagName("td")[0];
if(td.innerHTML.toUpperCase().indexOf(filter)>-1){
tr[i].style.display=""
}else{
tr[i.style.display="none";]
}
}
}
When I link the list and use an input tag in my HTML document it does not work. I am very new to javascript and hope any of you can help me to where I go wrong or what I should do differently.
Thanks!
try following jquery. txtSearch is the ID of input text field
$("#txtSearch").on("keyup", function () {
$("#mountains .divnodata").remove();
var value = $(this).val().toLowerCase();
$("#mountains tr td:nth-of-type(1)").filter(function () {
$(this).parent().toggle($(this).text().toLowerCase().indexOf(value) ==0);// >-1
});
if ($("#mountains tr:not(:first):visible").length == 0) {
$("#mountains").append("<tr class='divnodata'><td colspan='3'>No data</td></tr>");
}
});
Or try following Javascript
var bb = document.getElementById('txtSearch');
bb.addEventListener('keyup', function() {
var filter = this.value.toUpperCase();
var mm = document.getElementById('mountains');
var input = document.getElementById(txtSearch);
var tr = mm.getElementsByTagName("tr");
var td;var index=0;
for(i = 1; i< tr.length; i++){
index++;
td = tr[index].getElementsByTagName("td")[0];
if(td.innerHTML.toUpperCase().indexOf(filter)==0){
tr[index].style.display=""
}else{
tr[index].style.display="none";
}
}
});

onclick td element, only this one will change

I have an issue with onclick events.
I have a 3*3 table and when I click on a td element I want only this one to be change.
The code :
var CaseID = new Array(1, 2, 3, 4, 5, 6, 7, 8, 9);
var table = document.createElement("table");
for (a = 0; a < 3; a++) {
var tr = document.createElement("tr");
for (b = 0; b < 3; b++) {
var td = document.createElement("td");
td.onclick = function() {
// here I want to change backgroundColor into red, but only for the one I pressed
};
tr.appendChild(td);
}
table.appendChild(tr);
}
document.body.appendChild(table);
for (c = 0; c < CaseID.length; c++) {
document.getElementsByTagName("td")[c].id = CaseID[c];
}
table {
border-collapse:collapse;
}
tr, td {
height:50px;
width:50px;
border:1px #000 solid;
}
You can just set its style property's backgroundColor, as shown below. Within that onclick function, this refers to the element.
var CaseID = new Array(1, 2, 3, 4, 5, 6, 7, 8, 9);
var table = document.createElement("table");
for (a = 0; a < 3; a++) {
var tr = document.createElement("tr");
for (b = 0; b < 3; b++) {
var td = document.createElement("td");
td.onclick = function() {
this.style.backgroundColor = 'red';
};
tr.appendChild(td);
}
table.appendChild(tr);
}
document.body.appendChild(table);
for (c = 0; c < CaseID.length; c++) {
document.getElementsByTagName("td")[c].id = CaseID[c];
}
table {
border-collapse:collapse;
}
tr, td {
height:50px;
width:50px;
border:1px #000 solid;
}

Create table column-headers dynamically

Right now I cannot figure out how to add headers for all the columns in this code where a html-table are created dynamically
function createTableAndInsert(sqlArray) {
//create table dynamically - only one row by the moment
var table = document.createElement('table');
for (var i = 1; i < 2; i++) {
var tr = document.createElement('tr'); // row
for (var j = 0; j < 8; j++) {
var td = document.createElement('td'); //column
var text = document.createTextNode(sqlArray[j]); //cell
td.appendChild(text);
tr.appendChild(td);
}
table.appendChild(tr);
}
document.getElementById('single_fine_view').appendChild(table);
}
You can pass the header list separately to your function and add following code
function createTableAndInsert(sqlArray,headerList) {
var table = document.createElement('table');
var tr = document.createElement('tr'); // Header row
for (var j = 0; j < 8; j++) {
var th = document.createElement('th'); //column
var text = document.createTextNode(headerList[j]); //cell
th.appendChild(text);
tr.appendChild(th);
}
table.appendChild(tr);
for (var i = 1; i < 2; i++) {
var tr = document.createElement('tr'); // row
for (var j = 0; j < 8; j++) {
var td = document.createElement('td'); //column
var text = document.createTextNode(sqlArray[j]); //cell
td.appendChild(text);
tr.appendChild(td);
}
table.appendChild(tr);
}
document.getElementById('single_fine_view').appendChild(table);
}
Your structure is:
<tr>
<td>
<div></div>
<div></div>
</td>
</tr>
thead should be appended before each row.
<thead></thead>
<tr>
<td>
<div></div>
<div></div>
</td>
</tr>
Solution:
var thead = document.createElement('thead');
thead.innerHTML = 'Header';
Before table.appendChild(tr);, add this line table.appendChild(thead);
THEAD needs one or more TR elements:
var table = document.createElement('table'); // 'table' may be a reserved word
var tblHead = document.createElement('thead');
var rowHead = document.createElement('tr');
table.appendChild(tblHead);
tblHead.appendChild(rowHead)
for(j=0; j<8; j++) {
var celHead = document.createElement('th');
//the array txtHeaders[] should be passed to your function if you have the values in advance
// otherwise, you can access the header cells later by:
// table.getElementsbyTagName('th')[].innerHTML
celHead.innerHTML = txtHeaders[j]
rowHead.appendChild(celHead)
}
// now do your row & table loops

Giving unique id to table cell

I have created a table.
I have text input where I type some text. It refers to some element with special values.
When I click a button the productname is added to the table (using insertCell()).
I want to give a unique id to every new table element.
function add1() {
var row, cell;
var productname = document.getElementById("produkt1").value; // text input
var table = document.getElementById("pos1"); // button near text input
if(productname === "Egg") {
p = ["Egg", "", 20, 10, 11, 101];
}
if(productname === "Milk") {
p = ["Milk", "", 30, 5, 12, 75];
}
row = table.insertRow(2);
var c_id = 0;
for (var i = 0; i < p.length ; i++) {
cell = row.insertCell(i);
cell.innerHTML = p[i];
for (var j = 0; j < 1 ; j++) {
cell.id = 'tdp1' + k_id;
c_id++;
}
} // It only works for one element, and the others have the same id as elements from row1
}
a. There seems to be a type in the line cell.id = 'tdp1' + k_id; It is supposed to be c_id instead of k_id
b. You do not need the second for loop for anything and just can remove it.
The following code gives me a new row with ids for each cell (tdp10 to tdp15)
function add1() {
var row, cell;
var productname = document.getElementById("produkt1").value; // text input
var table = document.getElementById("pos1"); // button near text input
if(productname === "Egg") {
p = ["Egg", "", 20, 10, 11, 101];
}
if(productname === "Milk") {
p = ["Milk", "", 30, 5, 12, 75];
}
row = table.insertRow(2);
var c_id = 0;
for(var i = 0; i < p.length ; i++){
cell = row.insertCell(i);
cell.innerHTML = p[i];
cell.id = 'tdp1' + c_id;
c_id++;
}
}
I found solution:
function add1() {
var row, cell;
var productname = document.getElementById("produkt1").value;
var table = document.getElementById("pos1");
if(productname === "Egg") {
p = ["Egg", "", 20, 10, 11, 101];
}
if(productname === "Milk") {
p = ["Milk", "", 30, 5, 12, 75];
}
var cells = document.getElementsByClassName("pos");
row = table.insertRow(2);
for(var i = 0; i < p.length ; i++){
cell = row.insertCell(i);
cell.innerHTML = p[i];
cell.className = "pos";
for(var j = 0; j < cells.length ; j++){
cell.id = 'tdp1' + j;
}
}
I gave created cell a className. It's working, but thank you for help. :)
