<div class="description"><div class="ng-window-page"><p>A reference to the browser's <code>window</code> object. While <code>window</code>
|
|
is globally available in JavaScript, it causes testability problems, because
|
|
it is a global variable. In angular we always refer to it through the
|
|
<code>$window</code> service, so it may be overridden, removed or mocked for testing.</p>
|
|
<p>Expressions, like the one defined for the <code>ngClick</code> directive in the example
|
|
below, are evaluated with respect to the current scope. Therefore, there is
|
|
no risk of inadvertently coding in a dependency on a global value in such an
|
|
expression.</p>
