Hello Guys,
Have you thinking of Creating | Inserting | Fetching of data in HTML5. If yes then this
Blog will helps you a lot.
Yesterday I worked on a phonegap Application where my need is to provide offline
Access to my mobile Apps. Its very Simple using HTML5 offline access to local
Database .
Here , I am sharing with a sample code:
1. Creating Database and Table in HTML5:
This is, just a simple form. Of course, when you have a form, you want to capture the form submission somehow. In our case, we’ll use the new HTML5 local SQL database. We don’t need any servers or HTTP requests or anything except a compatible browser .
Here’s how we initialize the database:
Below can see that all we did here was add an
2. Inserting Data into the Table:
Now we’ll write a couple functions to help us insert subject into this table:
Hope this will helps some one.....

Here’s how we initialize the database:
Below can see that all we did here was add an
openDatabase
call and some SQL statements to create tables. These are just standard SQL statements (the reference SQL is from SQLite).
<!DOCTYPE html>
<html>
<head>
<title>Offline Storage</title>
<script src="http://www.google.com/jsapi"></script>
<script>
google.load("jquery", "1.4.1");
</script>
<script>
var db = window.openDatabase("Student", "", "Previous Course", 1024*1000);
$(document).ready(function() {
db.transaction(function(tx) {
tx.executeSql('CREATE TABLE IF NOT EXISTS Course(id INTEGER PRIMARY KEY, course_id
INTEGER, subject_one TEXT, subject_two TEXT, email TEXT)', []);
INTEGER, subject_one TEXT, subject_two TEXT, email TEXT)', []);
});
});
</script>
</head>
<body>
<form method="get" id="course_form">
<div>
<label for="1">Subject 1</label>
<input type="text" value="" id="subject1" name="subject1" placeholder="subject"/>
</div>
<div>
<label for="2">Subject 2</label>
<input type="text" value="" id="subject2" name="subject2" placeholder="subject" />
</div>
<div>
<input type="email" id="email" placeholder="Enter your email address" size="40"/>
</div>
<div>
<input type="submit" value="Upload Data" />
</div>
</form>
</body>
</html>
2. Inserting Data into the Table:
Now we’ll write a couple functions to help us insert subject into this table:
<!DOCTYPE html>
<html>
<head>
<title>OffLine Storage</title>
<script src="http://www.google.com/jsapi"></script>
<script>
google.load("jquery", "1.4.1");
</script>
<script>
var db = window.openDatabase("Student", "", "Previous Course", 1024*1000);
function insertSubject(subject_one, subject_two, course_id, email) {
db.transaction(function(tx) {
tx.executeSql('INSERT INTO Course (course_id, subject_one, subject_two, email)
VALUES (?, ?, ?, ?)', [course_id, subject_one, subject_two, email]);
VALUES (?, ?, ?, ?)', [course_id, subject_one, subject_two, email]);
});
}
$(document).ready(function() {
db.transaction(function(tx) {
tx.executeSql('CREATE TABLE IF NOT EXISTS Course(id INTEGER PRIMARY KEY, course_id
INTEGER, subject_one TEXT, subject_two TEXT, email TEXT)', []);
INTEGER, subject_one TEXT, subject_two TEXT, email TEXT)', []);
});
$('#course_form').submit(function() {
course = { 1: $('#subject1').val(), 2: $('#subject2').val() };
insertSubject($('#subject1').val(), $('#subject2').val(), 1, $('#email').val());
return false;
});
});
</script>
</head>
<body>
<form method="get" id="course_form">
<div>
<label for="1">Subject 1</label> <input type="text" value=""
id="subject1" name="subject1" placeholder="subject" />
</div>
<div>
<label for="2">Subject 2</label> <input type="text" value=""
id="subject2" name="subject2" placeholder="subject" />
</div>
<div>
<input type="email" id="email" placeholder="Enter your email address"
size="40" />
</div>
<div>
<input type="submit" value="Upload Data" />
</div>
</form>
</body>
</html>
</html>
3. Displaying | Fetching of data from the table :
Getting data inserted into our database was trivial, but now we want to show previously submitted data, right? This is easy, too. We’ll start with two changes: (1) show ALL previously submitted data upon loading the page, and (2) update this list whenever new data are submitted.

1024*1000);
function
insertSubject(subject_one, subject_two, course_id, email) {

{
tx.executeSql('INSERT

[course_id, subject_one, subject_two, email]);
});
}

renderResults(tx, rs) {
e

e.html("");
for(var

subject_two:
'
+ r['subject_two']
+ ',
email: '

+ '<br

}
}
function
displayData(email) {
db.transaction(function(tx)
{
if
(!(email === undefined)) {
tx.executeSql('SELECT
* FROM Course WHERE email = ?',
[email], renderResults);
}
else
{
tx.executeSql('SELECT

[], renderResults);
}
});
}
$(document).ready(function()
{
db.transaction(function(tx)
{
tx.executeSql('CREATE

course_id
INTEGER, subject_one TEXT, subject_two TEXT, email TEXT)',
[]);
});
$('#course_form').submit(function()
{
course
= { 1: $('#subject1').val(),
2: $('#subject2').val()
};
insertSubject($('#subject1').val(),
$('#subject2').val(),

displayData();

displayData();

Hello Android
Guys,
Have you
facing issue in Integrating QR Code scanner ?
Please follow
this steps:
Run this command from your terminal(for
mac/linux os)
svn
checkout http://zxing.googlecode.com/svn/trunk/
zxing-read- only
zxing-read- only
Also you can
find the full source code at this url
Step 2 : Build
zxing core using Apache Ant
You will need to
build the core project into a jar file using apache
ant
(download from here
http://ant.apache.org/ivy/download.cgi).
Using a shell or cmd prompt navigate to the root directory of
the downloaded zxing src and execute “ant -f core/build.xml”.
This will produce a file core/core.jar which
Using a shell or cmd prompt navigate to the root directory of
the downloaded zxing src and execute “ant -f core/build.xml”.
This will produce a file core/core.jar which
Step 3: Build
ZXing Android using Eclipse
Create a New Android
Project (File –> New –> Android Project).
Set the project name
to ZXing (or similar).
Select the “Create
project from existing source” radio button
Click “Browse” and
navigate to the android project that you downloaded
from
zxing and click
“OK” Select “Finish”
The project will not
currently build. We need to add the core.jar file (that
we
produced
in the previous step) into our project.
Right-click on ZXing
project –>
properties –> Java Build Path –> Add External Jars
–> Navigate to
and select core.jar
–> Open –> OK.
Actually, while we’re
here we should do one more very important thing!
Right-click on ZXing
project –> properties –> Android –> Scroll down
and
check/tick the “Is
Library” checkbox –> OK
Step 4:
Include ZXing Android into your project.
Within
Eclipse, Right-click on YOURPROJECTNAMEHERE project
–>
properties
–>Android –> Scroll down to Libraries section –>
Click Add –>
Select ZXing
(which should appear as an option as a result of
completing
previous
step).
Here ,I am sharing you a
full running Sample code . Just download it,
import
it into your Eclipse and
Run.
1. AndroidManifest.xml
1. AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.testqrcode" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="8" /> <uses-permission android:name="android.permission.CAMERA" /> <application android:icon="@drawable/ic_launcher" android:label="@string/app_name" > <activity android:name=".TestQRCodeActivity" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name="com.google.zxing.client.android.CaptureActivity" android:configChanges="orientation|keyboardHidden" android:screenOrientation="landscape" android:theme="@android:style/Theme.NoTitleBar.Fullscreen" android:windowSoftInputMode="stateAlwaysHidden" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> <intent-filter> <action android:name="com.google.zxing.client.android.SCAN" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> </activity> </application> </manifest>
2. TestQRCodeActivity.java
package com.testqrcode; import com.google.zxing.client.android.CaptureActivity; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.Toast; public class TestQRCodeActivity extends Activity { /** Called when the activity is first created. */ Button b1; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); b1 = (Button) findViewById(R.id.submit); b1.setOnClickListener(new OnClickListener() { public void onClick(View arg0) { // TODO Auto-generated method stub Intent intent = new Intent(TestQRCodeActivity.this, CaptureActivity.class); // Intent intent = new // Intent("com.google.zxing.client.android.SCAN"); intent.putExtra("SCAN_MODE", "QR_CODE_MODE"); startActivityForResult(intent, 0); } }); } public void onActivityResult(int requestCode, int resultCode, Intent intent) { if (requestCode == 0) { if (resultCode == 1) { // Handle successful scan String capturedQrValue = intent.getStringExtra("RESULT"); // String format = intent.getStringExtra("SCAN_RESULT_FORMAT"); Toast.makeText(TestQRCodeActivity.this, "Scan Result:" + capturedQrValue, Toast.LENGTH_SHORT) .show(); } else if (resultCode == RESULT_CANCELED) { // Handle cancel } } else { } } }I am also sharing the screen shot which helps you in configuring the build path and zxing as a library project.
May this will Helps you.
Enjoy
