Hello,

You may use following code:

var backEventListener = null;

var unregister = function() {
    if ( backEventListener !== null ) {
        document.removeEventListener( 'tizenhwkey', backEventListener );
        backEventListener = null;
        window.tizen.application.getCurrentApplication().exit();
    }
}

//Initialize function
var init = function () {
    // register once
    if ( backEventListener !== null ) {
        return;
    }
    
    // TODO:: Do your initialization job
    console.log("init() called");
    
    var backEvent = function(e) {
        if ( e.keyName == "back" ) {
            try {
                if ( $.mobile.urlHistory.activeIndex <= 0 ) {
                    // if first page, terminate app
                    unregister();
                } else {
                    // move previous page
                    $.mobile.urlHistory.activeIndex -= 1;
                    $.mobile.urlHistory.clearForward();
                    window.history.back();
                }
            } catch( ex ) {
                unregister();
            }
        }
    }
    
    // add eventListener for tizenhwkey (Back Button)
    document.addEventListener( 'tizenhwkey', backEvent );
    backEventListener = backEvent;
};

$(document).bind( 'pageinit', init );
$(document).unload( unregister );

Hello,

Also you can find sample if create new project in IDE using Multi Page Application template

Seoghyun Kang

Hello,

 

If you want to use the hardware back button, please refer the following code.

// Bind hardware back button.
window.addEventListener('tizenhwkey', function onTizenHwKey(e) {
    if (e.keyName === 'back') {
        // TODO
    }
});

 

There are many solution to return the previous page. It depends on your page movement processing.

Ex 1. Normal type

window.history.back();

 

Ex 2. TAU

tau.back();

 

 

Please refer it.

What is the meaning of "share"?

 

Do you want to share the timeline for Advertising on Facebook?

Hello,

For example you can use following in Web app:

Open facebook url from app with browser (better in separate window)
for example: https://www.facebook.com/sharer/sharer.php, 
perform authentication,
share any url

Hello,

add this code to init function:

// add eventListener for tizenhwkey
document.addEventListener('tizenhwkey', function(e) {
	if(e.keyName == "back") {
		try {
			tizen.application.getCurrentApplication().exit();
		} catch (error) {
			console.error("getCurrentApplication(): " + error.message);
		}
	}
});

Hello,

You can use Application API to exit from you app. More info:

https://developer.tizen.org/dev-guide/2.3.0/org.tizen.web.apireference/html/device_api/mobile/tizen/application.html#Application::exit

Tharun Reddy

hi am tharun,

in my application i have to provide the back button after seeing this mails i got the code for back button but,now where should i write this code??do i should write to each and every of my html page??

Armaan-Ul- Islam

If you use the comple solution shared by AVSukhov in first response you can set the code anywhere in js file, just include the file in html.

 

Or you can write code inside window onload() function then include the js file.

 

window.addEventListener("load",function(event) {
   
    tizen.application.getCurrentApplication().exit();
    // OR
    window.history.back();
    // OR
    tau.back();
    // based on need

},false);

hi, currently almost all of the sample/template apps come with this feature in Tizen Studio. If you define your home/main page id as 'main' and check a condition for this ID to exit the app. And for other id simply call window.history.back(); to go to previous page. 

window.addEventListener( 'tizenhwkey', function( ev ) {
    	if( ev.keyName === "back" ) {
		var page = document.getElementsByClassName( 'ui-page-active' )[0],
			pageid = page ? page.id : "";
		if( pageid === "main" ) {
			try {
			   tizen.application.getCurrentApplication().exit();
			} catch (ignore) {
		}
		} else {
			window.history.back();
		}
	  }
	} );

 

 

<div class="ui-page ui-page-active" id="main">
    	<header class="ui-header">
			<h2 class="ui-title">First Page</h2>
		</header>
		<div class="ui-content content-padding">
			
		</div>
</div>
