Insert Table Row Using JavaScript

mosko · 2025-02-27T03:11:04+0000

In this article we will create Insert Table Row using JavaScript. The program will dynamically create and insert a row in a HTML table. The trick of this code is to bind the form value as an id then create a table element using dot notation createElement(). To learn more about this, just follow the steps below.

Getting started:

First you have to download bootstrap framework, this is the link for the bootstrap that I used for the layout design https://getbootstrap.com/.

The Main Interface

This code contains the interface of the application. To create this just write these block of code inside the text editor and save this as index.html.

<!DOCTYPE hmtl>
<html

lang

=

"en"

>
<head

>
<meta

charset

=

"UTF-8"

name

=

"viewport"

content

=

"width=device-width, initial-scale=1"

/

>
<link

rel

=

"stylesheet"

type

=

"text/css"

href

=

"css/bootstrap.css"

/

>
</

head

>
<body

>
<nav class

=

"navbar navbar-default"

<div

=

"container-fluid"

<a

nav>
<div

class

"col-md-3"

></

div

<div

class

"col-md-6 well"

<h3

<center

><button

type

=

"button"

class

=

"btn btn-primary"

onclick

=

"insertRow();"

>

Insert row</

button

></

center

</

form

>
</

div

>
</

div

>
<script

src

=

"js/script.js"

></

script

>
</

body

>
</

html

Creating the Script

This code contains the script of the application. The code will dynamically insert a new row. To do this just copy and write these block of codes inside the text editor, then save it as script.js inside the js folder.

function

insertRow(

)

{
var

firstname=

document.getElementById

(

'firstname'

)

.value

;
var

lastname=

document.getElementById

(

'lastname'

)

.value

;
if

(

firstname ==

""

||

lastname ==

""

)

{
alert(

"Please enter something first!"

)

;
}

else

{
var

parent=

document.createElement

(

'tr'

)

;
var

col1=

document.createElement

(

'td'

)

;
var

col2=

document.createElement

(

'td'

)

;
var

text1=

document.createTextNode

(

firstname)

;
var

text2=

document.createTextNode

(

lastname)

;
col1.appendChild

(

text1)

;
col2.appendChild

(

text2)

;
parent.appendChild

(

col1)

;
parent.appendChild

(

col2)

;
document.getElementById

(

'result'

)

.appendChild

(

parent)

;
document.getElementById

(

'firstname'

)

.value

=

""

;
document.getElementById

(

'lastname'

)

.value

=

""

;
}
}
