Json + JqueryThere is no direct way to iterate over a Java List with jQuery, see the following case study : Spring controller @RequestMapping(value = “/”, method = RequestMethod.GET) public ModelAndView getPages() { List list = new ArrayList(); list.add(“List A”); list.add(“List B”); list.add(“List C”); list.add(“List D”); list.add(“List E”); ModelAndView model = new ModelAndView(“somepage”); model.addObject(“list”, list); return model; } JSP page, you can…

I received lot of requests from my readers that asked to me how to implement Pagination with jQuery, PHP and MySQL. so I had developed a simple tutorial. It’s looks big but very simple script. Take a look at this live demo
Pagination with jQuery, MySQL and PHP.


The tutorial contains three PHP files and two js files includes jQuery plugin.

-config.php (Database Configuration)
-pagination.php
-pagination_data.php
-jquery.js

English: A download symbol.

When our application does a task that takes a considerable amount of time, it is common sense to show the progress of the task to the user.
This is a good User Experience practice. In this tutorial i will be discussing the implementation of a process-progress dialog.

As an example, i am displaying a progress bar that runs while the app downloads an image from the web. And once the image is downloaded
completely i am showing the image in a image view. You could modify this example and try it with any file type you may wish. That could be fun!

Download Code

Creating new Project

1. Create a new project and fill all the details. File ⇒ New ⇒ Android Project
2. Open your main.xml are create a button to show download progress bar. Also define a ImageView to show downloaded image. Paste the following code in your main.xml

main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >
    <!-- Download Button -->
    <Button android:id="@+id/btnProgressBar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Download File with Progress Bar"
        android:layout_marginTop="50dip"/>
    <!-- Image view to show image after downloading -->
    <ImageView android:id="@+id/my_image"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"/>
</LinearLayout>

3. Now in your main activity class import necessary classes and buttons. I am starting a new asynctask to download the file after clicking on show progress bar button.

public class AndroidDownloadFileByProgressBarActivity extends Activity {
    // button to show progress dialog
    Button btnShowProgress
    // Progress Dialog
    private ProgressDialog pDialog;
    // Progress dialog type (0 - for Horizontal progress bar)
    public static final int progress_bar_type = 0;
    // File url to download
    private static String file_url = "http://api.androidhive.info/progressdialog/hive.jpg";
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        // show progress bar button
        btnShowProgress = (Button) findViewById(R.id.btnProgressBar);
        // Image view to show image after downloading
        my_image = (ImageView) findViewById(R.id.my_image);
        /**
         * Show Progress bar click event
         * */
        btnShowProgress.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // starting new Async Task
                new DownloadFileFromURL().execute(file_url);
            }
        });
    }

4. Progress Dialog can be shown using ProgressDialog class. It is a subclass of normal AlertDialog class. So add an alert method in your main activity class.

/**
 * Showing Dialog
 * */
@Override
protected Dialog onCreateDialog(int id) {
    switch (id) {
    case progress_bar_type:
        pDialog = new ProgressDialog(this);
        pDialog.setMessage("Downloading file. Please wait...");
        pDialog.setIndeterminate(false);
        pDialog.setMax(100);
        pDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
        pDialog.setCancelable(true);
        pDialog.show();
        return pDialog;
    default:
        return null;
    }
}

5. Now we need to add our Async Background thread to download file from url. In your main activity add a asynctask class and name it as DownloadFileFromURL(). After downloading image from the web i am reading the downloaded image from the sdcard and displaying in a imageview.

/**
 * Background Async Task to download file
 * */
class DownloadFileFromURL extends AsyncTask<String, String, String> {
    /**
     * Before starting background thread
     * Show Progress Bar Dialog
     * */
    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        showDialog(progress_bar_type);
    }
    /**
     * Downloading file in background thread
     * */
    @Override
    protected String doInBackground(String... f_url) {
        int count;
        try {
            URL url = new URL(f_url[0]);
            URLConnection conection = url.openConnection();
            conection.connect();
            // getting file length
            int lenghtOfFile = conection.getContentLength();
            // input stream to read file - with 8k buffer
            InputStream input = new BufferedInputStream(url.openStream(), 8192);
            // Output stream to write file
            OutputStream output = new FileOutputStream("/sdcard/downloadedfile.jpg");
            byte data[] = new byte[1024];
            long total = 0;
            while ((count = input.read(data)) != -1) {
                total += count;
                // publishing the progress....
                // After this onProgressUpdate will be called
                publishProgress(""+(int)((total*100)/lenghtOfFile));
                // writing data to file
                output.write(data, 0, count);
            }
            // flushing output
            output.flush();
            // closing streams
            output.close();
            input.close();
        } catch (Exception e) {
            Log.e("Error: ", e.getMessage());
        }
        return null;
    }
    /**
     * Updating progress bar
     * */
    protected void onProgressUpdate(String... progress) {
        // setting progress percentage
        pDialog.setProgress(Integer.parseInt(progress[0]));
   }
    /**
     * After completing background task
     * Dismiss the progress dialog
     * **/
    @Override
    protected void onPostExecute(String file_url) {
        // dismiss the dialog after the file was downloaded
        dismissDialog(progress_bar_type);
        // Displaying downloaded image into image view
        // Reading image path from sdcard
        String imagePath = Environment.getExternalStorageDirectory().toString() + "/downloadedfile.jpg";
        // setting downloaded into image view
        my_image.setImageDrawable(Drawable.createFromPath(imagePath));
    }
}

6. Open your AndroidManifest.xml file and add internet connect permission and writing to sdcard permission.

AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
    package="com.example.androidhive"
    android:versionCode="1"
    android:versionName="1.0" >
    <uses-sdk android:minSdkVersion="8" />
    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name=".AndroidDownloadFileByProgressBarActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
    <!-- Permission: Allow Connect to Internet -->
    <uses-permission android:name="android.permission.INTERNET" />
    <!-- Permission: Writing to SDCard -->
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
</manifest>

7. Run your Application and click on show progress bar button to see your progress bar. You can see the downloaded image in imageView once it is downloaded.

English: The text "jQuery" in the of...

Google Chrome has had extensions for a while now, but because the Linux client is a little farther behind I never got farther than the simple hello world tutorial. Today, however, I am pleased to announce that Chrome extensions are totally boss, and it is extremely easy to get a jQuery UI skinned template app going in 15 minutes, just by following three easy steps.

Step 1 – Brushing up on the Hello World Extension Tutorial

Follow the Getting Started (Hello World) tutorial. The tutorial is very well written and will help you get your bearings about what extensions can do and the minimum you need to get started. A key part is the manifest.json

CrashPlan for Business

{
  "name": "My First Extension",
  "version": "1.0",
  "description": "The first extension that I made.",
  "browser_action": {
    "default_icon": "icon.png"
  },
  "permissions": [
    "http://api.flickr.com/"
  ]
}

The name, version, and description fields are all self explanatory. The browser action one is interesting. It means that your extension will add a button to the browser (right after the address bar) with the specified icon. So far as I can tell the only thing that the button can do now is display a popup, though this popup can communicate with other parts of your extension. Permissions are also important, they specify what domains you can access via xmlhttprequests.

At this point you should have a working hello world tutorial, if not please continue to follow the rest of the directions on the full tutorial page, I’ll wait.

Step 2 jQuerying it up

After you finish the tutorial you may come to feel that raw JS is pretty harsh stuff and it would be great to get a little jQuery action in there. No need to fear, just add this to your “popup.html” file:

// <![CDATA[
src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js" type="text/javascript">
// ]]>

You don’t even need to add a file anywhere in your extension. Neat! Now you can rewrite the part of the tutorial that connects to the Flickr API like so:

$.get("http://api.flickr.com/services/rest/", {
    method: "flickr.photos.search",
    api_key: "90485e931f687a9b9c2a66bf58a3861a",
    text: "hello world",
    safe_search: 1,
    content_type: 1,
    sort: "relevance",
    per_page: 20
  }, function(data, status, request) {
    var photos = request.responseXML.getElementsByTagName("photo");    for (var i = 0, photo; photo = photos[i]; i++) {
      var img = document.createElement("image");
      img.src = constructImageURL(photo);
      document.body.appendChild(img);
    }
  }
);

Love that fresh jQuery scent. Note that I left the constructImageURL function unchanged, so you’ll still need it if you want the extension to continue working.

Step 3 Adding jQuery UI (It’s Easy!)

This is the easy part. Go to the jQuery UI custom build your own download. Keep all the UI stuff checked and choose your favorite theme, you’ll have plenty of time later to choose exactly what you want or need, but for now just focus on seeing how easy it is to integrate. Now download the zip and extract in into your extensions root directory.

You can go to chrome-extension://extensionId/index.html and see all the magic of the jQuery UI demo, but working from inside a Chrome Extension. Of course extensionId is whatever that giant random string of characters that Chrome assigned to your extension was, something like opnnhifacfpohionnikhlecfgheooenk. (Learn more here)

Congratulations!

Although getting a simple skeleton/hello world extension up only takes a short amount of time, learning about all the possibilities and actually making an extension that does great things will take much longer. I hope that with this tutorial that starting will be very easy and nothing will stand in the way of your dreams.

Peace!
