Answer : In backend there is global ajaxurl variable defined by WordPress itself. This variable is not created by WP in frontend. It means that if you want to use AJAX calls in frontend, then you have to define such variable by yourself. Good way to do this is to use wp_localize_script . Let's assume your AJAX calls are in my-ajax-script.js file, then add wp_localize_script for this JS file like so: function my_enqueue() { wp_enqueue_script( 'ajax-script', get_template_directory_uri() . '/js/my-ajax-script.js', array('jquery') ); wp_localize_script( 'ajax-script', 'my_ajax_object', array( 'ajax_url' => admin_url( 'admin-ajax.php' ) ) ); } add_action( 'wp_enqueue_scripts', 'my_enqueue' ); After localizing your JS file, you can use my_ajax_object object in your JS file: jQuery.ajax( { type: "post", dataType: "json", url: my...

Answer : Today I had the same problem with some Espresso tests and it was getting me crazy because everything seemed normal. Finally I discovered the problem was because the method annotated with @BeforeClass was throwing an exception. If something goes wrong in that method, the stacktrace of the exception is not shown in the Log window of the Run tab but in the Log window of the Android Monitor tab If you want to reproduce the problem just add this to your testing class: @BeforeClass public static void setupClass() { throw new RuntimeException("Sorry dude, you won't find any test!"); } This can happen when the type of your run configuration is incorrect. With me, this goes wrong when running an Espresso test which used to be a unit test. For some reason it still uses the Android JUnit test configuration when running this test. Manually creating an Android Instrumented Test solves the problem. Just for posterity sakes, here's the solution that worke...

Answer : Try it with a keydown or keyup event to capture the Esc key. In essence, you can replace document:keypress with document:keydown.escape : @HostListener('document:keydown.escape', ['$event']) onKeydownHandler(event: KeyboardEvent) { console.log(event); } It worked for me using the following code: const ESCAPE_KEYCODE = 27; @HostListener('document:keydown', ['$event']) onKeydownHandler(event: KeyboardEvent) { if (event.keyCode === ESCAPE_KEYCODE) { // ... } } or in shorter way: @HostListener('document:keydown.escape', ['$event']) onKeydownHandler(evt: KeyboardEvent) { // ... } Modern approach, event.key == "Escape" The old alternatives ( .keyCode and .which ) are Deprecated. @HostListener('document:keydown', ['$event']) onKeydownHandler(event: KeyboardEvent) { if (event.key === "Escape") { // Do things } }

Answer : [Update: as of Go 1.8, GOPATH defaults to $HOME/go , but you may still find this useful if you want to understand the GOPATH layout, customize it, etc.] The official Go site discusses GOPATH and how to lay out a workspace directory. export GOPATH="$HOME/your-workspace-dir/" -- run it in your shell, then add it to ~/.bashrc or equivalent so it will be set for you in the future. Go will install packages under src/ , bin/ , and pkg/ , subdirectories there. You'll want to put your own packages somewhere under $GOPATH/src , like $GOPATH/src/github.com/myusername/ if you want to publish to GitHub. You'll also probably want export PATH=$PATH:$GOPATH/bin in your .bashrc so you can run compiled programs under $GOPATH . Optionally, via Rob Pike, you can also set CDPATH so it's faster to cd to package dirs in bash: export CDPATH=.:$GOPATH/src/github.com:$GOPATH/src/golang.org/x means you can just type cd net/html instead of cd $GOPATH/src/golang....
