Im making a blackjack game for an assignment and have arrays for leaderboard and cards.
I want to print the leader board like this. CARDS(in individual cells)| TOTAL.
help would be appreciated, thanks
function makeTable(leaderBoard) {
var table = document.createElement('table');
for (var i = 0; i < leaderBoard.length; i++) {
var row = document.createElement('tr');
for (var j = 0; j < leaderBoard[i].length; j++) {
var cell = document.createElement('td');
cell.textContent = leaderBoard[i][j];
row.appendChild(cell);
}
table.appendChild(row);
}
document.getElementById('leaderBoard').innerHTML = table;
}
Maybe the example input isn't in the correct format, but reusing a predefined table and html table functions such as insertRow and insertCell (not necessarily better, but they can be easier on the eye than createElement and append) :
<div id="leaderBoard"><table id=leaderTable></table></div>
function updateleaderboard(leaderBoard) {
var table = document.getElementById('leaderTable');
while(table.rows.length > 0) table.deleteRow(0); //remove prev values, if any
for (var i = 0; i < leaderBoard.length; i++) { //If the function is always used on a winner (no ties), the loop isn't really needed
var row =table.insertRow();
var arrCards = leaderBoard[i++];
var total = row.insertCell();
total.className = 'res';
total.textContent = leaderBoard[i];
arrCards.forEach(function(c,ind){
row.insertCell(ind).textContent = c;
});
}
}
var cards = [['Q','4','5'],19];
updateleaderboard(cards);
Fiddle
function makeTable(leaderBoard) {
var table = document.createElement('table');
var row = document.createElement('tr');
for (var i = 0; i < leaderBoard[0].length; i++) {
var cell = document.createElement('td');
cell.textContent = leaderBoard[0][i];
row.appendChild(cell);
}
var cell = document.createElement('td');
cell.textContent = "Total: " + leaderBoard[1];
row.appendChild(cell);
table.appendChild(row);
document.getElementById('leaderBoard').appendChild(table);
}
var userCards = ["Card 1", "Card 2", "Card 3"];
var userTotal = 10;
makeTable([userCards, userTotal]);

I want to type text inside the cell but I tried to set attribute with td but it doesn't work. Please help me how can I set attribute to type text in the cell. Thank you for your help!
function addTable() {
rn = window.prompt("Input number of rows", 1);
cn = window.prompt("Input number of columns",1);
var myTableDiv = document.getElementById("myDynamicTable");
var table = document.createElement('TABLE');
table.border = '1';
var tableBody = document.createElement('TBODY');
table.appendChild(tableBody);
for (var i = 0; i < parseInt(rn, 10); i++) {
var tr = document.createElement('TR');
tableBody.appendChild(tr);
for (var j = 0; j < parseInt(cn, 10); j++) {
var td = document.createElement('TD');
td.width = '75';
td.appendChild(document.createTextNode("text"));
tr.appendChild(td);
}
}
myTableDiv.appendChild(table);
}
addTable();
You need to create an input element and then append that to td:
rn = window.prompt("Input number of rows", 1);
cn = window.prompt("Input number of columns", 1);
var myTableDiv = document.getElementById("myDynamicTable");
var table = document.createElement('TABLE');
table.border = '1';
var tableBody = document.createElement('TBODY');
table.appendChild(tableBody);
for (var i = 0; i < parseInt(rn, 10); i++) {
var tr = document.createElement('TR');
tableBody.appendChild(tr);
for (var j = 0; j < parseInt(cn, 10); j++) {
var td = document.createElement('TD');
td.width = '75';
var input = document.createElement('input');
input.setAttribute('type', 'text');
input.setAttribute('value', 'text');
td.appendChild(input);
tr.appendChild(td);
}
}
myTableDiv.appendChild(table);
<div id="myDynamicTable">
</div>
You can use contenteditable attribute: td.contenteditable = 'true';.
Depending on how you want to use this value, you might also insert an input element.
You are perhaps looking for contentEditable?
function addTable() {
const rn = +window.prompt("Input number of rows", 1);
const cn = +window.prompt("Input number of columns", 1);
const myTableDiv = document.getElementById("myDynamicTable");
const table = document.createElement('table');
table.border = '1';
const tableBody = document.createElement('tbody');
table.appendChild(tableBody);
for (let i = 0; i < rn; i++) {
var tr = document.createElement('tr');
tableBody.appendChild(tr);
for (let j = 0; j < cn; j++) {
var td = document.createElement('td');
td.width = '75';
td.contentEditable = true;
td.appendChild(document.createTextNode("text"));
tr.appendChild(td);
}
}
myTableDiv.appendChild(table);
}
addTable();
<div id="myDynamicTable"></div>
if you want to operate on tables, use corrects javascript instructions ...
const
DynTb = document.getElementById('myDynamicTable')
rn = +window.prompt("Input number of rows", 1)
, cn = +window.prompt("Input number of columns", 1)
;
if( isNaN(rn) || isNaN(cn))
throw 'bad integer input value (s)'
const myTable = addTable(DynTb, rn, cn )
function addTable(tDiv, rn, cn)
{
let
tab = tDiv.appendChild( document.createElement('table') )
, tBy = tab.createTBody()
;
for(let r=0;r<rn;++r)
{
let row = tBy.insertRow()
for(let c=0;c<cn;++c)
{
row.insertCell().innerHTML =
`<input type="text" placeHolder="${r}-${c}">`
} }
return tab
}
table {
border-collapse : collapse;
margin : 2em 1em;
}
td {
padding : .2em;
border : 1px solid darkblue;
}
input {
width : 5em;
}
<div id="myDynamicTable"></div>
I have a table generated from an array. I'm looking to add a hyperlink to the entire first column of the <tbody> and only the first column.
I am able to add the <a> after the table is created, but then it doesn't actually contain the url within it, it simply appends to what already exists.
Specifically, how can I add a hyperlink to the first column of the
<tbody>?
Generally, as the table is being made, how can I specify different
things (anchors, classes, styles, etc.) for different columns?
http://jsfiddle.net/nateomardavis/n357gqo9/10/
$(function() {
google.script.run.withSuccessHandler(buildTable)
.table();
});
//TABLE MADE USING for
function buildTable(tableArray) {
var table = document.getElementById('table');
var tableBody = document.createElement('tbody');
var tbodyID = tableBody.setAttribute('id', 'tbody');
for (var i = 0; i < tableArray.length; ++i) {
var column = tableArray[i];
var colA = column[0];
var colB = column[1];
var colC = column[2];
var colD = column[3];
if (colA != "") {
var row = document.createElement('tr');
var getTbody = document.getElementById('tbody');
for (var j = 0; j < column.length; ++j) {
var cell = document.createElement('td');
cell.appendChild(document.createTextNode(column[j]));
row.appendChild(cell);
//NEXT TWO LINES DO NOT WORK
var firstCol = getTbody.rows[i].cells[0];
firstCol.setAttribute('class', 'TEST');
}
}
tableBody.appendChild(row);
}
table.appendChild(tableBody);
document.body.appendChild(table);
/* WORKS AFTER TABLE IS CREATED BUT CAN'T CAPUTRE INTERNAL LINK
var getTbody = document.getElementById('tbody');
for (var i = 0; i < getTbody.rows.length; i++) {
var firstCol = getTbody.rows[i].cells[0]; //first column
//firstCol.style.color = 'red';
//firstCol.setAttribute('class', 'TEST');
var link = document.createElement('a');
firstCol.appendChild(link);
}
*/
}
I'm checking for duplicates in a table. What I'm trying to accomplish is when I display the first column if it is the same value as the previous row I don't want to display the value. I'm finding the duplicates but I get an error when I try to hide them by using display. style ="none"; My code is below.
I'm Thanking You In Advance
PD
var data=[['e',0,1,2,3,4], ['a',54312,235,5,15,4], ['a',6,7,8,9,232],
['a',54,11235,345,5,6], ['b',0,1,2,3,4], ['b',54312,235,5,15,4],
['c',62,15,754,93,323], ['d',27,11235,425,18,78], ['d',0,1,2,3,4],
['d',54312,235,5,15,4], ['e',6,7,8,9,232], ['e',54,11235,345,5,6],
['e',0,1,2,3,4], ['e',54312,235,5,15,4], ['e',62,15,754,93,323],

//Create a HTML Table element.
var table = document.createElement("TABLE");
var somedata = document.createElement("TD");
var dvTable = document.getElementById("dvTable");
var elems = document.getElementsByClassName("tableRow");
//Get the count of columns.
var columnCount = data[0].length;
//Add the data rows.
for (var i = 0; i < data.length; i++) {
var row = table.insertRow(-1);
for (var j = 0; j < columnCount; j++) {
//Searching for duplicates
var num = data[i][0];
for (var otherRow = i + 1; otherRow < data.length; otherRow++) {
var dup = data[otherRow][0];
console.log("What is the dup" + dup);
if (num === dup)
{
console.log("duplicate");
dvTable[i].style.display = "none";
}
}
var cell = row.insertCell(-1);
cell.innerHTML = data[i][j];
cell.innerHtml = myZero;
}
}
dvTable is an HTML table element. You can't access the row using dvTable[i].
Try -
dvTable.rows(i).cells(j).style.display = none;
I am trying to create a minefield game with javascript.
When I click on clear ro**w it gives "passed" but sometimes "died" too or clicking on **mined row gives sometimes "passed". It's supposed to give only "passed" with clear and "died" with mined row.
I can't figure out the reason..
Could you see it?
Here is my code so far:
var level = 9;
// create the table
var body = document.getElementsByTagName("body")[0];
var tbl = document.createElement("table");
tbl.setAttribute('id', 'myTable');
var tblBody = document.createElement("tbody");
//Create 2d table with mined/clear
for (var i = 1; i <= 10; i++) {
var row = document.createElement("tr");
document.write("<br/>");
for (var x = 1; x <= 10; x++) {
var j = Math.floor(Math.random() * 50);
if (j <= 15) {
j = "mined";
} else {
j = "clear";
}
var cell = document.createElement("td");
var cellText = document.createTextNode(j + "");
cell.appendChild(cellText);
row.appendChild(cell);
}
tblBody.appendChild(row);
}
tbl.appendChild(tblBody);
body.appendChild(tbl);
tbl.setAttribute("border", "1");
//Check which row is clicked
window.onload = addRowHandlers;
function addRowHandlers() {
var table = document.getElementById("myTable");
var rows = table.getElementsByTagName("td");
for (p = 0; p < rows.length; p++) {
var currentRow = table.rows[p];
var createClickHandler = function (row) {
return function () {
var cell = row.getElementsByTagName("td")[1];
var id = cell.innerHTML;
if (id == "mined") {
alert("Died");
} else {
alert("Passed!");
}
};
}
currentRow.onclick = createClickHandler(currentRow);
}
}
JSFiddle Here:

Thanks in advance!
Its' this line, which causes the faulty behaviour: var cell = row.getElementsByTagName("td")[1]; Everytime a click is made, the [1] selects the 2nd cell of a column, no matter which cell was actually clicked.
I modified your fiddle: http://jsfiddle.net/ykuyE/1
The onclick handler is now applied to the individual cell directly, when the table is created.
cell.onclick = function() {
if (this.innerHTML == "mined") {
alert("Died");
} else {
alert("Passed!");
}
}
I am trying to write a Javascript function which writes the text to (eventually) create the following html tables (I will be passing different length arguments to it to create hundreds of tables):
<table>
<tr><td><u>School</u></td>
<td><u>Percent</u></td>
<tr><td>School 1: </td>
<td>Percent1</td></tr>
<tr><td>School 2: </td>
<td>Percent2</td></tr>
<tr><td>School 3: </td>
<td>Percent3</td></tr>
</table>
The inputs that I have are comma separated strings:
var school_list = "School 1, School 2, School 3"
var pct_list = "Percent1, Percent2, Percent3"
The function needs to be passed school_list and pct_list, and return a string of the html table code above.
Something like this:
var schoolArr = school_list.split(',');
var pctArr = pct_list.split(',');
var table = "<table>";
for (var i=0; i< schoolArr.length; i++) {
table = table + "<tr><td>"+ schoolArr[i]+"</td><td>"+ pctArr[i] +"</td></tr>";
}
table = table + "</table>";
return table;
You can try below code with Jsfiddle demo ::
function createTable(tab) {
var tar = document.getElementById(tab);
var table = document.createElement('TABLE');
table.border = '1';
var tbdy = document.createElement('TBODY');
table.appendChild(tbdy);
for (var j = 0; j < 4; j++) {
var tr = document.createElement('TR');
tbdy.appendChild(tr);
for (var k = 0; k < 2; k++) {
var td = document.createElement('TD');
td.width = '100';
if (k == 0) td.innerHTML = "School" + (j + 1);
else td.innerHTML = "Percent" + (j + 1);
tr.appendChild(td);
}
}
tar.appendChild(table);
}
createTable('tab');
<div id="tab"></div>
var schools = school_list.split(/,\s*/g).join('</td><td>');
var pcts = pct_list.split(/,\s*/g).join('</td><td>');
return '<table><tr><td>' + schools + '</td></tr><tr><td>' + pcts + '</td></tr></table>'
or a better approach is to construct the whole table in DOM and place it in document directly.
function appendTD(tr, content) {
var td = document.createElement('td');
td.appendChild(document.createTextNode(content));
tr.appendChild(td);
}
var table = document.createElement('table');
school_list.split(/,\s*/g).forEach(appendTD.bind(null, table.appendChild(document.createElement('tr'))));
pct_list.split(/,\s*/g).forEach(appendTD.bind(null, table.appendChild(document.createElement('tr'))));
someParent.appendChild(table);
var numberOfSchools = school_list.split(',');
var numberOfPercent = pct_list.split(',');
var htmlOutput= '<table><tr><td><u>School</u></td><td><u>Percent</u></td>';
for(var i = 0 ; i < numberOfSchools.length; i++)
{
htmlOutput += "<tr><td>" + numberOfSchools[i] + "</td>";
htmlOutput += "<td>"+numberOfPercent[i] +"</td></tr>"
}
htmlOutput += "</table>"
And return htmlOutput
Here's a DOM method, highlighs why innerHTML is so popular. DOM methods are pretty fast in execution lately, but the amount of code is a bit tiresome unless there's a good reason to use it.
The amount of code can be significantly reduced with a couple of helper functions so it is on par with innerHTML methods:
var school_list = "School 1, School 2, School 3"
var pct_list = "Percent1, Percent2, Percent3"
function makeTable(schools, percents) {
// Turn input strings into arrays
var s = schools.split(',');
var p = percents.split(',');
// Setup DOM elements
var table = document.createElement('table');
var tbody = table.appendChild(document.createElement('tbody'));
var oRow = document.createElement('tr');
var row;
oRow.appendChild(document.createElement('td'));
oRow.appendChild(document.createElement('td'));
table.appendChild(tbody);
// Write header
row = tbody.appendChild(oRow.cloneNode(true));
row.childNodes[0].appendChild(document.createTextNode('School'));
row.childNodes[1].appendChild(document.createTextNode('Percent'));
// Write rest of table
for (var i=0, iLen=s.length; i<iLen; i++) {
row = tbody.appendChild(oRow.cloneNode(true));
row.childNodes[0].appendChild(document.createTextNode(s[i]));
row.childNodes[1].appendChild(document.createTextNode(p[i]));
}
document.body.appendChild(table);
}
It can be called after the load event, or just placed somewhere suitable in the document:
window.onload = function() {
makeTable(school_list, pct_list);
}
