Onsen UI 1.0.4 Released with Tabbar and Navigator Enhancements

Hope you are having a good day! Today, we released a new version of Onsen UI with a few new enhancements and bug fixes.

Tabbar Improvements

New event for a changed tab item

Now you can get notified when active tab is changed. To do so, specify a function to on-active-tab-changed attribute.

    on-active-tab-changed="onTabChanged($index, $tabItem)">

And write the callback in the controller.

$scope.onTabChanged = function($index, $tabItem){
    console.log('tab changed to', $index);

As illustrated on the code above, we can get the $index and the $tabItem of the new tab.

Activate a tab from the code

Before 1.0.4, tab can be activated only by tapping the tab. Now you can activate the tab from your controller using setActiveTab(INDEX).

Calling from the controller:

$scope.ons.tabbar.setActiveTab(0); // Show first tab

Or, calling from ng-click or similar directives:

<ons-button ng-click="ons.tabbar.setActiveTab(1)">
    Show second tab

CSS class for active tab item

When a tab is activated, an active class is added to the topcoat-tab-bar__item element.This make it easy to customize tabbar appearance.

For example:


CSS definition:

.home-icon {    
    background-image: url(icon.png);
    background-size: 100%;
    width: 30px;
    height: 30px;
    margin: 0 auto !important;

.active .home-icon { /* When active state */
    border: 1px solid red;

Pass and retrieve parameters between pages

You can now add parametters into navigator push page’s options and retrieve them back via getCurrentPage() method.

// Pass parameters to another page
ons.navigator.pushPage("path/to/page.html", {foo: "bar"})

// Retrieve parameters from the other page
ons.navigator.getCurrentPage() //  "bar"

// Retrieve the current page
ons.navigator.getCurrentPage() //  "path/to/page.html"

// Retrieve the entire stack
ons.navigator.getPages() //  [pageObj1, pageObj2, ... , pageObjN]

An example to change the behavior of the back button:

 document.addEventListener("backbutton", function (e) {
        if ($rootScope.ons.navigator.getPages().length > 1) {
        } else {
}, false);

Ons-text-input with type

Now you can use type attribute to change the keyboard layout.

<ons-text-input type="number"/>
<ons-text-input type="password"/>
<ons-text-input type="email"/>
<ons-text-input type="tel"/> // Telephone
<ons-text-input type="date"/>
