<p id="shortdesc">Example of using the Select interaction.</p>
|
|
<div id="docs"><p>Choose between <code>Single-click</code>, <code>Click</code>, <code>Hover</code> and <code>Alt+Click</code> as the event type for selection in the combobox below. When using <code>Single-click</code> or <code>Click</code> you can hold do <code>Shift</code> key to toggle the feature in the selection.</p>
|
|
<p>Note: when <code>Single-click</code> is used double-clicks won't select features. This in contrast to <code>Click</code>, where a double-click will both select the feature and zoom the map (because of the <code>DoubleClickZoom</code> interaction). Note that <code>Single-click</code> is less responsive than <code>Click</code> because of the delay it uses to detect double-clicks.</p></p>
|
|
<p><p>In this example, a listener is registered for the Select interaction's <code>select</code> event in order to update the selection status below. <form class="form-inline">
