Auto Search Using JavaScript

Jonny · Thursday at 3:10 AM

In this code we will tackle about Auto Search using JavaScript. The program will enable to automatically search a row data. You are free to modify, and use this code. 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 html>
<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

class

=

"container-fluid"

>
<a

class

=

"navbar-brand"

href

=

"https://sourcecodester.com"

>

</

nav>
<div

<div

<label

<div

<div

"input-group-addon"

><span

class

"glyphicon glyphicon-search"

></

span

></

div

<input

type

=

"text"

id

=

"search"

placeholder=

"Search here..."

onkeyup

=

"autoSearch()"

class

=

"form-control"

<script

"js/script.js"

</

</

html

Creating the Script

This code contains the script of the application. The code will automatically search a specific keyword. 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.

var

members =

[

'Tony Stark'

,

'Jin Mori'

,

'Luke Cage'

]

;
displayMember(

)

;
function

displayMember(

)

{
members.sort

(

function

(

a,

b)

{
if

(

a <

b)

{
return

-

1

;
}
if

(

a >

b)

{
return

1

;
}
return

0

;
}

)

;
data =

""

;
for

(

var

i=

0

;

i <

members.length

;

i++

)

{
data +=

"<tr><td>"

+

members[

i]

+

"</td></tr>"

;
}
document.getElementById

(

'result'

)

.innerHTML

=

data;
}
function

autoSearch(

)

{
var

search=

document.getElementById

(

'search'

)

.value

.toLowerCase

(

)

;
var

parent=

document.getElementById

(

"result"

)

;
var

children=

parent.getElementsByTagName

(

'tr'

)

;
for

(

var

i=

0

;

i<

children.length

;

i++

)

{
var

keyword=

children[

i]

.innerText

;
if

(

keyword.toLowerCase

(

)

.indexOf

(

search)

>-

1

)

{
children[

i]

.style

.display

=

""

;
}

else

{
children[

i]

.style

.display

=

"none"

;
}
}
}
