I have a table where the user is able to add customers and when a customer is added, a unique ID is given to the row and each cell within the row.
As you can see, when you add a row, I have logged the row.id and the cell.id, however, the cell.id is supposed to be 'cell_' + rowCount + '_' + i but the rowCount in the cell does not match the one in the row.
// add customer or item
// append row to the HTML table
var rowCount = 1;
var cellCount = 0;
function appendRow(id, style) {
var table = document.getElementById(id); // table reference
length = table.length,
row = table.insertRow(table.rows.length); // append table row
row.setAttribute('id', style);
var i;
row.id = 'row' + rowCount;
rowCount++
// insert table cells to the new row
for (i = 0; i < table.rows[0].cells.length; i++) {
createCell(row.insertCell(i), i, 'cell_' + rowCount + '.' + i); // starts over when row changes
cellCount++
}
}
function createCell(cell, text, style) {
var div = document.createElement('div'), // create DIV element
txt = document.createTextNode('_'); // create text node
div.appendChild(txt); // append text node to the DIV
div.setAttribute('id', style); // set DIV class attribute
div.setAttribute('idName', style); // set DIV class attribute for IE (?!)
cell.appendChild(div); // append DIV to the table cell
console.log(row.id + ' ' + div.id);
}
table {
text-align: center;
}
td {
width: 100px;
}
tr:nth-child(even) {
background-color: #fff;
}
tr:nth-child(odd) {
background-color: #eee;
}
<button id="addCust" class="addSort" onclick="appendRow('custList')">add customer</button>
<div class="custScroll">
<table id="custListTop" contenteditable="false">
<tr>
<td style="border-top-left-radius: 5px;">Customers</td>
<td>Work #</td>
<td>Cell #</td>
<td style="border-top-right-radius: 5px;">Main Location</td>
</tr>
</table>
<table id="custList" contenteditable="true">
<tr>
<td>Someone</td>
<td>903-636-0000</td>
<td>903-626-0000</td>
<td>something</td>
</tr>
</table>
</div>
You have
row.id = 'row' + rowCount;
rowCount++
followed by
'cell_' + rowCount
You are first using rowCount on the row when it's set to 1, then setting it to 2, then using it on the cell when it's set to 2.
I want to create a table by click a button,and i need to save the table to the database .this is the code to create table but i think this is so long,how can i create it fast?
var div = document.createElement("div");
var table1 = document.createElement("table");
var table2 =document.createElement("table");
var thead = document.createElement("thead");
var th1 = document.createElement("th");
var th2 = document.createElement("th");
var th3 = document.createElement("th");
th1.innerHTML="Count";
th2.innerHTML="Date";
th3.innerHTML="Price";
document.body.appendChild(div);
div.appendChild(table1);
div.appendChild(table2);
table2.appendChild(thead);
thead.appendChild(th1);
thead.appendChild(th2);
thead.appendChild(th3);
If the code is too long then I recommend creating an html table structure inside a div that is not displayed. Then when the user clicks the button then you could
Display the table that is hidden.
Clone the table and append it to something (if you expect to create the table multiple times)
Your code would then look like so (cloning wise):
jQuery:
$('#myButton').on('click', function(){
$(document.body).append($('original').clone());
});
Javascript:
document.getElementById('myButton').onclick = function(){
document.body.appendChild(document.getElementById('original').cloneNode());
}
And here is the html table you can have hidden.
<div style="display: none;">
<table id="original">
<tr>
<td>Jill</td>
<td>Smith</td>
<td>50</td>
</tr>
<tr>
<td>Eve</td>
<td>Jackson</td>
<td>94</td>
</tr>
</table>
</div>
This reduces greatly your javascript code.
If you want to make some enhancement than you can use precompiled template like muchtache.js :
<table>
<tr>
<th> Count </th>
<th> Date </th>
<th> Price </th>
</tr>
{{#jsonObject}}
<tr>
<td>{{Count1}}</td>
<td>{{Date1}}</td>
<td>{{Price1}}</td>
</tr>
{{/jsonObject}}
</table>
in javascript, you can write your javascript jsonobject as :
jsonobject : [{
count1 : 1,
date1 : 12/12/2012,
price1 : 100
},
{
count1 : 2,
date1 : 12/12/2013,
price1 : 200
}
]
for full muchtache example visit Json Object into Mustache.js Table
The following function might help:
function html2dom (html) {
var div = document.createElement('div');
div.innerHTML = html;
return div.removeChild(div.firstChild);
}
Here is how to use it:
document.body.appendChild(html2dom(''
+ '<div>'
+ '<table></table>'
+ '<table>'
+ '<thead>'
+ '<th>Count</th>'
+ '<th>Date</th>'
+ '<th>Price</th>'
+ '</thead>'
+ '</table>'
+ '</div>'
));
Live demo:
document.body.appendChild(html2dom(''
+ '<div>'
+ '<p>Paragraph.</p>'
+ '<ul>'
+ '<li>Item 1.</li>'
+ '<li>Item 2.</li>'
+ '<li>Item 3.</li>'
+ '</ul>'
+ '</div>'
));
function html2dom (html) {
var div = document.createElement('div');
div.innerHTML = html;
return div.removeChild(div.firstChild);
}
I'm trying to figure out how to use javascript to add rows to a table dynamically. I tested without the table and can get the data but am stumped on populating the table.
I have a function call on a button that is supposed to populate the table. below is my code so far:
<table id="tblData" class="pure-table">
<thead>
<tr>
<th>Staff</th>
<th>Orders</th>
</tr>
</thead>
<tbody>
<!--<tr class="pure-table-odd">
<td>Jim</td>
<td>2</td>
</tr>-->
</tbody>
</table>
function getData()
{
var soData = JSON.parse(staffOrders);
var i = 0;
var c = getRowCount();
//build table
var table = document.getElementById("tblData");
while (i <= c) {
//alert(soData[i].staffName + " had " + soData[i].orders + " orders.");
//"<td>" + soData[i].staffName + "</td>"
//"<td>" + soData[i].orders + "</td>"
i++;
}
}
You need to use the DOM API for the HTML table element. It's documented at
http://www.w3schools.com/jsref/dom_obj_table.asp
Here's an example taken from http://www.w3schools.com/jsref/met_table_insertrow.asp :
// Find a <table> element with id="myTable":
var table = document.getElementById("myTable");
// Create an empty <tr> element and add it to the 1st position of the table:
var row = table.insertRow(0);
// Insert new cells (<td> elements) at the 1st and 2nd position of the "new" <tr> element:
var cell1 = row.insertCell(0);
var cell2 = row.insertCell(1);
// Add some text to the new cells:
cell1.innerHTML = "NEW CELL1";
cell2.innerHTML = "NEW CELL2";
function getData() {
var responseData = [{
"staffName": "Wilkerson Bowman",
"orders": 26
}, {
"staffName": "Finley Nunez",
"orders": 26
}, {
"staffName": "Katie Estrada",
"orders": 7
}];
var thead = document.querySelector('#tblData thead');
responseData.forEach(function(data) {
var row = document.createElement('tr');
row.innerHTML = '<td>' + data.staffName + '</td><td>' + data.orders + '</td>';
thead.appendChild(row);
});
}
getData();
<table id="tblData" class="pure-table">
<thead>
<tr>
<th>Staff</th>
<th>Orders</th>
</tr>
</thead>
<tbody></tbody>
</table>
try this code
window.onload = function(){
function getData() {
var soData = [{orders : 'order1', staffName : 'staffName1'}, {orders : 'order2', staffName : 'staffName2'}]
var i = 0;
var c = 2;
//build table
var table_body = document.getElementById("tblData").getElementsByTagName('tbody')[0];
while (i <= c) {
var tr = document.createElement('tr');
tr.className = "pure-table-odd"; // add class in tr
var td1 = document.createElement('td');
td1.innerHTML = soData[i].orders;
var td2 = document.createElement('td');
td2.innerHTML = soData[i].staffName;
tr.appendChild(td1);
tr.appendChild(td2);
table_body.appendChild(tr);
i++;
}
};
getData();
}
<table id="tblData" class="pure-table">
<thead>
<tr>
<th>Staff</th>
<th>Orders</th>
</tr>
</thead>
<tbody>
<!--<tr class="pure-table-odd">
<td>Jim</td>
<td>2</td>
</tr>-->
</tbody>
</table>
I have a JavaScript function which creates a table with 3 rows 2 cells.
Could anybody tell me how I can create the table below using my function (I need to do this for my situation)?
Here is my javascript and html code given below:
function tableCreate() {
//body reference
var body = document.getElementsByTagName("body")[0];
// create elements <table> and a <tbody>
var tbl = document.createElement("table");
var tblBody = document.createElement("tbody");
// cells creation
for (var j = 0; j <= 2; j++) {
// table row creation
var row = document.createElement("tr");
for (var i = 0; i < 2; i++) {
// create element <td> and text node
//Make text node the contents of <td> element
// put <td> at end of the table row
var cell = document.createElement("td");
var cellText = document.createTextNode("cell is row " + j + ", column " + i);
cell.appendChild(cellText);
row.appendChild(cell);
}
//row added to end of table body
tblBody.appendChild(row);
}
// append the <tbody> inside the <table>
tbl.appendChild(tblBody);
// put <table> in the <body>
body.appendChild(tbl);
// tbl border attribute to
tbl.setAttribute("border", "2");
}
<table width="100%" border="1">
<tr>
<td> </td>
<td> </td>
</tr>
<tr>
<td> </td>
<td rowspan="2"> </td>
</tr>
<tr>
<td> </td>
</tr>
</table>
Slightly shorter code using insertRow and insertCell:
function tableCreate() {
const body = document.body,
tbl = document.createElement('table');
tbl.style.width = '100px';
tbl.style.border = '1px solid black';
for (let i = 0; i < 3; i++) {
const tr = tbl.insertRow();
for (let j = 0; j < 2; j++) {
if (i === 2 && j === 1) {
break;
} else {
const td = tr.insertCell();
td.appendChild(document.createTextNode(`Cell I${i}/J${j}`));
td.style.border = '1px solid black';
if (i === 1 && j === 1) {
td.setAttribute('rowSpan', '2');
}
}
}
}
body.appendChild(tbl);
}
tableCreate();
Also, this doesn't use some "bad practices", such as setting a border attribute instead of using CSS, and it accesses the body through document.body instead of document.getElementsByTagName('body')[0];
This should work (from a few alterations to your code above).
function tableCreate() {
var body = document.getElementsByTagName('body')[0];
var tbl = document.createElement('table');
tbl.style.width = '100%';
tbl.setAttribute('border', '1');
var tbdy = document.createElement('tbody');
for (var i = 0; i < 3; i++) {
var tr = document.createElement('tr');
for (var j = 0; j < 2; j++) {
if (i == 2 && j == 1) {
break
} else {
var td = document.createElement('td');
td.appendChild(document.createTextNode('\u0020'))
i == 1 && j == 1 ? td.setAttribute('rowSpan', '2') : null;
tr.appendChild(td)
}
}
tbdy.appendChild(tr);
}
tbl.appendChild(tbdy);
body.appendChild(tbl)
}
tableCreate();
function addTable() {
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 < 3; i++) {
var tr = document.createElement('TR');
tableBody.appendChild(tr);
for (var j = 0; j < 4; j++) {
var td = document.createElement('TD');
td.width = '75';
td.appendChild(document.createTextNode("Cell " + i + "," + j));
tr.appendChild(td);
}
}
myTableDiv.appendChild(table);
}
addTable();
<div id="myDynamicTable"></div>
Here is the latest method using the .map function in javascript.
You create a table in html and then insert body with javascript.
const data = [{Name:'Sydney', Day: 'Monday', Time: '10:00AM'},{Name:'New York', Day: 'Monday',Time: '11:00AM'},]; // any json data or array of objects
const tableData = data.map(value => {
return (
`<tr>
<td>${value.Name}</td>
<td>${value.Day}</td>
<td>${value.Time}</td>
</tr>`
);
}).join('');
const tableBody = document.querySelector("#tableBody");
tableBody.innerHTML = tableData;
<table border="2">
<thead class="thead-dark">
<tr>
<th scope="col">Tour</th>
<th scope="col">Day</th>
<th scope="col">Time</th>
</tr>
</thead>
<tbody id="tableBody">
</tbody>
</table>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<table id="myTable" cellpadding="2" cellspacing="2" border="1" onclick="tester()"></table>
<script>
var student;
for (var j = 0; j < 10; j++) {
student = {
name: "Name" + j,
rank: "Rank" + j,
stuclass: "Class" + j,
};
var table = document.getElementById("myTable");
var row = table.insertRow(j);
var cell1 = row.insertCell(0);
var cell2 = row.insertCell(1);
var cell3 = row.insertCell(2);
cell1.innerHTML = student.name,
cell2.innerHTML = student.rank,
cell3.innerHTML = student.stuclass;
}
</script>
</body>
</html>
This solution will be perfect when you want rows and columns dynamic. You can accept rows and columns as arguments.
function tableCreate(row, col){
let body = document.body;
let tbl = document.createElement('table');
tbl.style.width = '200px';
tbl.style.border = '1px solid black';
for(let i = 0; i < row; i++){
let tr = tbl.insertRow();
for(let j = 0; j < col; j++){
let td = tr.insertCell();
td.appendChild(document.createTextNode(`${i},${j}` ));
td.style.border = '1px solid black';
}
}
body.appendChild(tbl);
}
tableCreate(4,4);
Output -
<!DOCTYPE html>
<html>
<body>
<p id="p1">
<b>Enter the no of row and column to create table:</b>

function create() {
var row = parseInt(document.getElementById("row").value);

var tableend = "</table>";
var trstart = "<tr bgcolor=#ff9966>";
var trend = "</tr>";
var tdstart = "<td>";

var data="data in cell";
var str1=tablestart + trstart + tdstart + data + tdend + trend + tableend;
document.write(tablestart);
for (var r=0;r<row;r++) {
document.write(trstart);
for(var c=0; c<col; c++) {
document.write(tdstart+"Row."+r+" Col."+c+tdend);

}
document.write(tableend);
document.write("<br/>");

}
function deleteTable() {

Might not solve the problem described in this particular question, but might be useful to people looking to create tables out of array of objects:
function createTable(objectArray, fields, fieldTitles) {
let body = document.getElementsByTagName('body')[0];
let tbl = document.createElement('table');
let thead = document.createElement('thead');
let thr = document.createElement('tr');
fieldTitles.forEach((fieldTitle) => {
let th = document.createElement('th');
th.appendChild(document.createTextNode(fieldTitle));
thr.appendChild(th);
});
thead.appendChild(thr);
tbl.appendChild(thead);
let tbdy = document.createElement('tbody');
let tr = document.createElement('tr');
objectArray.forEach((object) => {
let tr = document.createElement('tr');
fields.forEach((field) => {
var td = document.createElement('td');
td.appendChild(document.createTextNode(object[field]));
tr.appendChild(td);
});
tbdy.appendChild(tr);
});
tbl.appendChild(tbdy);
body.appendChild(tbl)
return tbl;
}
createTable([
{name: 'Banana', price: '3.04'},
{name: 'Orange', price: '2.56'},
{name: 'Apple', price: '1.45'}
],
['name', 'price'], ['Name', 'Price']);
I hope you find this helpful.

I wrote a version that can parse through a list of objects dynamically to create the table as a string. I split it into three functions for writing the header columns, the body rows, and stitching it all together. I exported as a string for use on a server. My code uses template strings to keep things elegant.
If you want to add styling (like bootstrap), that can be done by adding more html to HEAD_PREFIX and HEAD_SUFFIX.
// helper functions
const TABLE_PREFIX = '<div><table class="tg">';
const TABLE_SUFFIX = '</table></div>';
const TABLE_HEAD_PREFIX = '<thead><tr>';
const TABLE_HEAD_SUFFIX = '</tr></thead>';
const TABLE_BODY_PREFIX = '<tbody><tr>';
const TABLE_BODY_SUFFIX = '</tr></tbody>';
function generateTableHead(cols) {
return `
${TABLE_HEAD_PREFIX}
<td>#</td>
${cols.map((col) => `<td>${col}</td>`).join('')}
${TABLE_HEAD_SUFFIX}`;
}
function generateTableBody(cols, data) {
return `
${TABLE_BODY_PREFIX}
${data.map((object, index) => `
<tr><td>${index}</td>
${cols.map((col) => `<td>${object[col]}</td>`).join('')}
</tr>`).join('')}
${TABLE_BODY_SUFFIX}`;
}
/**
* generate an html table from an array of objects with the same values
*
* #param {array<string>} cols array of object columns used in order of columns on table
* #param {array<object>} data array of objects containing data in a single depth
*/
function generateTable(data, defaultCols = false) {
let cols = defaultCols;
if (!cols) cols = Object.keys(data[0]); // auto generate columns if not defined
return `
${TABLE_PREFIX}
${generateTableHead(cols)}
${generateTableBody(cols, data)}
${TABLE_SUFFIX}`;
}
Here's an example use:
const mountains = [
{ height: 200, name: "Mt. Mountain" },
{ height: 323, name: "Old Broken Top"},
]
const htmlTableString = generateTable(mountains );
var btn = document.createElement('button');
btn.innerHTML = "Create Table";
document.body.appendChild(btn);
btn.addEventListener("click", createTable, true);
function createTable(){
var div = document.createElement('div');
div.setAttribute("id", "tbl");
document.body.appendChild(div)
document.getElementById("tbl").innerHTML = "<table border = '1'>" +
'<tr>' +
'<th>Header 1</th>' +
'<th>Header 2</th> ' +
'<th>Header 3</th>' +
'</tr>' +
'<tr>' +
'<td>Data 1</td>' +
'<td>Data 2</td>' +
'<td>Data 3</td>' +
