Angular 2 Router No Base Href Set

Image
Answer : https://angular.io/docs/ts/latest/guide/router.html Add the base element just after the <head> tag. If the app folder is the application root, as it is for our application, set the href value exactly as shown here. The <base href="/"> tells the Angular router what is the static part of the URL. The router then only modifies the remaining part of the URL. <head> <base href="/"> ... </head> Alternatively add >= Angular2 RC.6 import {APP_BASE_HREF} from '@angular/common'; @NgModule({ declarations: [AppComponent], imports: [routing /* or RouterModule */], providers: [{provide: APP_BASE_HREF, useValue : '/' }] ]); in your bootstrap. In older versions the imports had to be like < Angular2 RC.6 import {APP_BASE_HREF} from '@angular/common'; bootstrap(AppComponent, [ ROUTER_PROVIDERS, {provide: APP_BASE_HREF, useValue : '/' }); ]); < RC.0

Android: StopService Doesn't Call OnDestroy

Answer : First, it's onDestroy, not OnDestroy . Second, you must use the @Override annotation for compile-time checking, so your Service code should look somewhat like this: @Override public void onDestroy(){ Log.v("SERVICE","Service killed"); player.stop(); super.onDestroy(); } First, you need to clarify how many types of services in Android. AFAIK, there are: Foreground service. Background service. Bound service. Intent service. These services stop in different ways. Foreground: only stop when you intentionally stop it by calling stopService() in activity or fragment where you start that service or call stopSelf() in its own service. And Please note only these methods trigger service's onDestroy() . Background: stopService() and stopSelf() do in the same way as foreground. Moreover, you should know this service is in the same thread with activity or fragment calling it, so if you destroy activity or fragment, this ser

Control The Dashed Border Stroke Length And Distance Between Strokes

Image
Answer : The native dashed border property value does not offer control over the dashes themselves... so bring on the border-image property! Brew your own border with border-image Compatibility : It offers great browser support (IE 11 and all modern browsers). A normal border can be set as a fallback for older browsers. Let's create these These borders will display exactly the same cross-browser! Step 1 - Create a suitable image This example is 15 pixels wide by 15 pixels high and the gaps are currently 5px wide. It is a .png with transparency. This is what it looks like in photoshop when zoomed in: This is what it looks like to scale: Controlling gap and stroke length To create wider / shorter gaps or strokes, widen / shorten the gaps or strokes in the image.

Add A Quantity Field To Ajax Add To Cart Button On WooCommerce Shop Page

Answer : Updated on May 2020 For WooCommerce versions from 3.2 to 4+, Optimized jQuery code and Removed a quantity bug. The following custom function is hooked in woocommerce_loop_add_to_cart_link filter hook and adds a quantity input field to each product on WooCommerce archives pages and other product loops. We use here mostly the original WooCommerce code. A bit of jQuery code is necessary to update the data-quantity attribute on the add to cart button when customer changes the quantity. Some styling might be needed, depending on your client wishes (and on your theme) . An additional section to hide the "View cart" button is located at the end. The code: add_filter( 'woocommerce_loop_add_to_cart_link', 'quantity_inputs_for_loop_ajax_add_to_cart', 10, 2 ); function quantity_inputs_for_loop_ajax_add_to_cart( $html, $product ) { if ( $product && $product->is_type( 'simple' ) && $product->is_purchasable() &&am
